IT- 1 Upgrading Underutilized Biomass Resources for the Growing Low-Carbon Bioeconomy

Lew P. Christopher Biorefining Research Institute, Lakehead University, Thunder Bay P7B 5Z5, Ontario, Canada

Abstract: The global trend for production of bioenergy and bioproducts from renewable resources is currently steered by three important drivers: 1) diminishing reserves of readily recoverable oil and fluctuating oil prices; 2) growing food and energy needs; and 3) increasing greenhouse gas (GHG) emissions. Lignocellulose Biorefineries are our future oil refineries where oil is inevitably replaced by lignocellulosic biomass – the most abundant and renewable resource on earth. Biorefineries are viewed as one of the major economic pillars of the emerging global Bioeconomy [1]. However, less than 10% of the global fuels and chemicals production is currently biobased as bioproducts are not yet cost-competitive to their petroleum-based counterparts. In response to these challenges, the Biorefinery concept is continuously being updated and enriched with new ideas and innovative approaches that aim to: 1) improve the efficiency of the biorefining technology through smart integration of the thermo-chemical and biochemical conversion routes; 2) develop new value-added bioproducts from biomass with multi-purpose end-uses. Examples include valorization of underutilized hemicellulose, lignin and protein side-streams generated at pulp and paper mills; development of new performance chemicals and advanced fiber materials that expand the markets beyond the traditional pulp and paper value chain to include food, feed, pharmaceutical, automotive and other applications. As the biomass feedstock may comprise half or more the total production costs, upgrading biomass side-streams into value-added products,in alignment with the circular bioeconomy approach, can lower the bioenergy, biochemicals and biomaterials production costs, waste treatment costs, carbon footprint and GHG emissions. This presentation will provide an overview of recent advances in the Biorefinery development and related technological, socio-economic and market challenges that we need to overcome in our transition to a low-carbon bioresource economy. Examples [2-5] for development of advanced cellulose-derived biopolymers, functionalized lignin-based materials and biofuels production of low-cost industrial by-products will be provided and discussed. Keywords: biorefineries; bioeconomy; biomass

IT- 2 Generating Sugar Streams from Pulp and Paper Mill Sludge for Biofuel Application Vasudeo Zambare*, Lew Christopher

Biorefining Research Institute, Lakehead University,Canada *Email: [email protected]

Abstract: Non-ionic surfactants have been reported to enhance the hydrolytic potential of enzymes in bioconversion of cellulosic substrates to glucose. The objective of this investigation was to evaluate the efficiency of enzymatic hydrolysis in production of fermentable sugars from primary sludge using a commercial cellulase preparation (Cellic® CTec2). Sludge contained 22.5% dry solids of which 58.1% was glucan and 16.8% ash. Following a mild pretreatment with hydrochloric acid,the ash content of sludge was reduced to 6.1% ash which reduced the inhibitory effect of ash on enzyme activity. Among the different surfactants studied in this investigation, PEG 4000 facilitated the highest glucose recovery of over 70% from the total available glucose. This represented a 2fold-increase in glucose yield over control without surfactant. Response surface methodological analysis at four variable factors (solid loadings, enzyme loadings, PEG 4000 concentration, and hydrolysis time) revealed that enzymatic hydrolysis was significantly enhanced using interactive effect of all factors whereas ANOVA test indicated solid and enzyme loadings as the most significant factors (p < 0.05). Development of efficient methods for production of renewable fuels from lignocellulosic biomass is necessary to maximize yields and reduce operating costs. One of the main challenges to industrial application of the lignocellulosic conversion process is the high costs of cellulolytic enzymes. Present investigation revealed that up to 37% of the cellulase enzyme can be recovered from the hydrolysate using a 3 kDa ultrafiltration membrane. A glucose yield of nearly 70% from the maximum was achieved using 25% recovered enzyme supplemented with 75% fresh enzyme. This demonstrates the potential of enzyme recycling as a strategy for reduction of glucose production costs. The fermentabilty of sludge hydrolsate containing 20g/L glucose was verified in production of 9.3 g/L bioethanol using Saccharomyces cerevisiae D5A and 13.6% of lipid accumulation in Cutaneotrichosporonoleaginosum.

IT- 3 Trace detection of food adulterant and industrial pollutant using Ag nanostructures SERS substrate S. D. Sartale Thin Films and Nanomaterials Laboratory, Department of Physics,Savitribai Phule Pune University,Pune-411007, INDIA Email: [email protected]

Abstract: Milk always has been the soft target for adulterants. Water, melamine, whey, vegetable oil, urea, soap solution, protein and milk from different speciesare the economically motivated adulterations which are used to adulterate the milk.Melamine consists of 66% of nitrogen by its mass and food industry detects nitrogen content in order to confirm the purity of the milk.Therefore, many adulterant uses melamine as primary choice to adulterate the milk. Adding 1.0 g of melamine in 1.0 kg of liquid milk can falsely increase protein content up to 5%.On the other hand textile industry uses artificial dyes in order to color the fabrics where many of them toxic and harmful to the human life and environment. Waste water produced in textile industries consist of various toxic dyes such as methylene blue, rhodamine b, crystal violet, malachite green, etc. These dyes are toxic and carcinogenic in nature and can be harmful to the human health when comes into contact. Therefore it is much needed to have highly sensitive and real time detection technique to detect the adulteration and industrial pollutant. Capable of detecting almost everything with large Raman scattering cross section SERS proved to be the highly sensitive and real time detection technique. In the SERS technique molecule is adsorbed in the proximity of plasmonic metal nanoparticles surface which results into the huge enhancement in normal Raman peak intensity and quenching of fluorescent background. Plasmonic metal nanoparticles always have been the best candidate for the SERS substrate because of their fascinating plasmonic properties. Au, Ag, Cu are the prominent candidate for the SERS substrate in the visible region of electromagnetic wave. Among the trio Ag nanoparticles serves best SERS substrate giving rise to the large SERS enhancement due to its narrow plasmonic resonance band width in the visible region.

IT- 4 Nanomaterials: Development, Expectations, and Challenges in the 21st Century

Rupesh S. Devan Discipline of Metallurgy Engineering and Materials Science, Indian Institute of Technology Indore, Simrol, 453552, India E-mail: [email protected]

Abstract: Nanoscience, nanotechnology, nanostructure, and nanomaterials have now become common words not only in research publications but also in day to day life. Nanomaterials hold potential to make supercomputers that are small enough to be carried in a shirt pocket or machines that can repair damaged tissues by traveling through the human body. Nanostructured materials are expected to be utilized in many different applications, including displays, supercapacitor, batteries, sensors, optical filters, laser, controlled drug delivery, and biological detection, to name a few. Overall nanomaterials offer the potential to solve some of the humanity’s most vexing challenges and are a critical driver of future economic growth worldwide. With its broad range of prospective uses, nanomaterials offer the promise of transformational change in virtually every industry, from aerospace and energy to healthcare and agriculture. Enormous efforts have been made to synthesize and characterize nanomaterials in the size range of 1-100 nm. Their property varies/enhance with the morphological forms such as 0D, 1D 2D, and 3D, making them suitable for a wide variety of applications. Miniaturization of these structures by physical and mechanical techniques is approaching the theoretical limits of about 50 nm. On the other hand, chemical synthesis techniques are acting as alternative methods to enable further miniaturization of the nanostructures. Even after vast development in the field of nanomaterials, all forms of nanomaterials do still offer some drawbacks. For examples, in comparison with the bulk materials, the low dimension and small size make the melting points lower but the resistivity higher, so the thermal and chemical stability of the nanostructures may be weakened. Therefore, to come up with the expectation of 21st century, we need to face the challenges offered by nanomaterials and should work efficiently for their development.

IT- 5 Surface Modification of Polymers by Low Temperature Plasma

D. P. Subedi*, H. Baniya, U.M.Joshi, G. Panta, R. Guragain Department of Natural Sciences, School of Science, Kathmandu Univrsity, Dhulikhel E-mail: [email protected]

Abstract: Low temperature plasmas have drawn much attention in the past few decades due to their wide range of applications such as thin film technology, polymer and textile processing, ozone generation and most recently to biomedicine. Surface modification of polymers by plasma provides reproducible, uniform, cost-effective and environmentally friendly means compared to conventional methods. In this paper, surface modification of polymers using low temperature plasma generated in the form of Dielectric Barrier Discharge (DBD) in air and air-argon medium is presented. The discharge was produced in parallel plate electrode system using high voltage power supply (18 kVrms) operating at 50 Hz. The main objective of the study was to investigate the change in wettability of the polymers after the treatment under different condition of discharge. Plasma treated samples were characterized by contact angle (CA) measurement, SEM and AFM analysis. Contact angle data were used to calculate surface energy and its polar and non-polar components. The results showed that a significant increase in wettability can be achieved even after a short treatment time of less than one minute in the plasma. It was found that the treatment was more effective with air-argon discharge compared to the air discharge. Keywords: Surface modification, plasma, DBD, wettability, contact angle, surface energy, SEM, AFM

IT- 6 Advanced Functional Materials for Sustainable Energy Storage Technologies

Dr. Deepak Dubal School of Chemical Engineering, University of Adelaide, Australia

Abstract: In the world of energy storage, supercapacitors and batteriesconstitute the most obvious example that you cannot have it all. Orcan you? High-power-density supercapacitors (SCs) are handicappedby low energy densities whereas the best among batteries,Li-ion batteries (LIBs), feature the best energy densities but lagbehind in power. Yet, they both are in the midst of intense developmentsgiven the expansion of energy storage markets [1,2].Thus, the race is on to develop new energy storage materialsand systems, which could deliver high energy at high rates[3-5] and, of course, at low cost.The performance of these energy storage systems (supercapacitors(SCs) and batteries) is strongly controlled by the electrode materials. Therefore, the proper selection, design, and fabrication of electrodematerials and devices are considered to be the most important factorsfor engineering high-performance energy storage devices.In thistalk, we will discuss a number of the technologies that are being developed to address these challenges, based on advances in functional materials- from conventional supercapacitors, Liion batteries to their hybrid combinations (Supercapacitor-Battery), beyond Li-ion battery for small-to-large scale energy storage applications. In all cases,advances in electrode materials, and/or ionic materials as electrolytes and hybrid device designs are enabling these developments.

IT- 7 A. Utilization of CO2 as a C1-Building Block for Fine Chemical Synthesis B. A New Class of PN3*-Pincer Ligands for Metal-Ligand Cooperative Catalysis

Sandeep Gholap KAUST Catalysis Center and Division of Physical Sciences and Engineering King Abdullah University of Science and Technology (KAUST) Thuwal 23955-6900, Saudi Arabia

Abstract: Carbon dioxide, a green and sustainable resource defining new paradigm to synthesis of carboxylic acids is received increasing attention from both academia and industry. Highlight of recent research is to find various substrates for carboxylation reaction via carbometalation reactions because such reactions offer formation of new multiple bonds through C-C bond formation with CO2 in regioselective manner. Herein, I will talk about the potential substrate as ynamides and allenamides having various N-heterocycles which offers, up on carboxylation, the various carboxylic acid derivatives containing N-heterocycles known as amino acid derivatives could be formed selectively. The new investigation of carboxylation of ynamides and allenamides via carbometalation reactions using various less reactive mild alkali reagents such as dialkylzinc and functionalized alkylzinc halides in presence of catalytic amount of copper complexes in one pot. These mild reagents act as alkyl source to which up on reaction of ynamides and allenamides offers perfect regioselectivity for carbon dioxide insertion through the co-ordination of copper complex with the N-carbmate moiety of ynamides and allenamides. Such strategy offers a new direction to control the regioselectivity in product. Pincer transition metal complexes have versatile reactivities to catalyze many organic transformations and to activate strong chemical bonds. In particular, complexes with ligand derived from tridentate pyridine-based framework exhibit interesting reactivities. It has been demonstrated that unique bond activation reactions can be achieved through aromatization– dearomatization of the central pyridine ring. In our group, we prepared a series of transition metal catalysts based on a novel class of pincer-type PN3 ligands which are capable of interacting with the substrates during the reaction. This “metal-ligand cooperative catalysis’’ model offers unprecedented reactivities. References: 1) Takimoto, M.; Gholap, S. S.; Hou, Z.Chem. Eur. J. 2015, 21, 15218. 2) Gholap, S.

IT- 8 Recent developments in Surface Analysis using XPS Dr.Karthick Balasubramanian Molecular Spectroscopy & Surface Analysis, Thermo Fisher Scientific India Pvt. Ltd. Email: [email protected]

Abstract:Over the past decade improved instrument reliability and automation has led to a broader use of X-ray Photoelectron Spectroscopy (XPS); changing from a specialist technique only performed by dedicated practitioners to a routine analysis tool that is widespread throughout academia and industry. The basic process is shown here.

As the X-rays radiate the sample, the electrons become excited and are emitted as photoelectrons. The kinetic energy of these are then measured by the analyser to determine the electron's binding energy. The binding energy depends on the element, the orbital from which the electron was ejected, and the chemical state of the element as well. So these three factors determine how much binding energy an electron has, and so we can hence determine what our sample is composed of. In typical operation, with the use of a monochromated aluminium anode, XPS has an information depth of approximately 10 nm. Depth profiling(shown below) allows determining the chemical composition further within the bulk is to sputter away layers of material, exposing the underlying substrate, allowing a profile of the chemical composition with substrate depth to be generated through iterative cycles of sputtering and spectra reacquisition.These methods for analysis are common on XPS systems.

XPS systems are controlled by a software that is available on all systems, and this provides everything from system control, data acquisition, experiment options, to the collecting of the data. Then once the data is collected it can be processed and even reported out to other software. It has a full suite of tools to help processing; from peak fitting, to principal component analysis, to maximum entropy calculators for angle resolved data. Software is also continuously being updated, and there are some new features that will be highlighting here.This presentation will discuss the theory and technical developments available with the new generation XPS systems from Thermo Fisher Scientific and the many benefits it provides to the user. This presentation will also discuss the different capabilities of the individual techniques and look on several applications, including metals, coatings, activated carbon, semi-conductors and polymers.

IT- 9 Integrated proteomics and metabolomics approach to elucidate the apomictic pathway in Cenchrus polystachion (L.)

Deepti Somayajula and Neetin Desai* Amity Institute of Biotechnology, Amity University Mumbai, India Email: [email protected]

Abstract: Indian agriculture has been a paradox, since production is growing up and also exports are growing. Seed is one of the key factors of crop productivity. The role of seed industry is not only to produce adequate quantity of quality seeds but also to achieve varietal diversity to suit various agro-climatic zones of the country. Therefore, a comprehension of the mechanisms underlying seed formation in cultivated plants is crucial for the quantitative and qualitative progress of agricultural production. Apomixis is an intriguing trait in plants that results in maternal clones through seed reproduction. It is an elusive, but potentially revolutionary, trait for plant breeding and hybrid seed production & has the potential to revolutionize agriculture if its basis can be elucidated. The availability of omics technology is a boon for providing such data sets that provide systems-level measurements for virtually all types of cellular components involved in apomixis. To address this dearth, we developed an integrated approach combining the two techniques to study the factors governing the process of apomixis. We studied the differential expression of proteins and metabolites in six tissues of the plant and their role in apomictic pathway. High throughput analysis by LC Q TOF MS and GC GC TOF MS were used for differential expression studies. 45, 38, 41, 30, 23 and 17 proteins and 6118, 6784, 6192, 6615, 5797 and 5791 metabolites were identified in Leaf, Stigma, Ovary, Seed , anther sac and pollen respectively. This data was further annotated by the use of pathway analysis tools Metaboanalyst and ImPaLa. This work gave a fine picture of general signalling, regulatory and metabolic pathways that appear to be linked with apomictic mechanism. In particular, we conclude on having the prominent role of sphingolipid metabolism, glycerol phospholipid metabolism, Pantothenate & CoA biosynthesis and Inositol Phosphate metabolism along with other short cycles on the process of apomixis. Thus the advantage of employing different approaches of global proteome and metabolome‐wide techniques, combined with more targeted analysis can unravel biological networks for apomixis in plants.

IT- 10 Spintronics – A new approach in Nano Devices Rajeev Shesha Joshi Department of Physics, Central University of Karnataka, Kalaburagi – 585367

Abstract: Spintronics is a budding area of active research which has contributed significantly to the development of new conceptual devices with tremendous potential of innovation ahead, both in terms of fundamental science and technology. Here, one exploits the spin degree of freedom of the electrons along with its charge. So, spintronics combines standard electronics with spin dependent effects1,2. In standard electronics one manipulates the electrons by using their charge to store or process information. In spintronics one manipulates electrons by using their spin along with their charge to process or store information. Hence one can expect a new generation of devices with completely different functionality3. In the talk I will try to explain the basic concepts of Spintronics and the devices presently used in the field, at a popular level. Further I will try to put forth the idea of Magnetic Anisotropy based Spintronic devices. I will try to elaborate our work in the area of magnetic nano wire based devices. I will explain the efforts

using NiFe based Nano wires4. The

micromagnetic simulation results and the related experimental outputs will be presented5. I will conclude with the glimpse of recent developments and future scope in the area of Spintronics.

IT- 11 Designing time and cost-effective upstream process for antibody fragment production: rHu biosimilar Ranibizumab a case study Dr. Rahul Bhambure* Chemical Engineering and Process Development Division, CSIR-National Chemical Laboratory (NCL), Dr. Homi Bhaba Road, Pune-411008 Email: [email protected]

Abstract: This investigation was focussed on developing high throughput cloning, expression and high cell density fermentation process for time and cost-effective manufacturing of biosimilar rHu Ranibizumab. The amino acid sequence for light and heavy chain of Ranibizumab was adopted from the drug bank database. Escherichia coli BL21 (DE3) and two redox mutants of E. coli with an oxidative cytoplasm were cloned using the codon-optimized light and heavy chain genes inserted into a T7 promoter-based expression vector for expressing the antibody fragment. Preliminary studies were performed at the shake flask culture scale followed by subsequent scale-up to a 1 L bioreactor. In the batch as well as fed-batch fermentation processes, cell mass and productivity were maximized by optimizing the experimental parameters like media composition and devising an optimal feeding strategy. A novel induction strategy was adopted for controlling the equal expression of light and heavy chain genes of rHu Ranibizumab.

IT- 12 Stem Cells, Cell Therapy and Their Applications Dr. Vinayak Kedage, Lab. Director Address: Regrow Biosciences Pvt. Ltd., 22, Shah Industrial Estate Nangargaon, Lonavala 410401 MS INDIA Email: [email protected]

Abstract: The potential impact of stem cell technology and cell therapy on medical practice is vast as stem cell technology combines the efforts of cell biologists, geneticists, and clinicians that provide the foundation for future therapies for a variety of malignant and non-malignant diseases and also reveal unique insights into basic disease mechanisms. Therefore, an understanding of stem cell technology is necessary for clinicians in the future. Stem cells are defined as totipotent progenitor cells capable of self-renewal and multilineage differentiation and now days their uses in malignant and nonmalignant diseases are very common. Apart from that, Cell therapy is being considered for, or has already shown to aid in, the repair of multiple tissue types in such wide-ranging therapeutic areas as cardiovascular disease, peripheral arterial disease, liver disease, diabetes, neurodegenerative disorders, bone/cartilage repair, and spinal cord injuries. The two types cellular therapies are vying for the emerging cell therapy market: autologous (patient specific) and allogeneic (patient independent). Stem cells and adult cell therapy have great potential in tissue regeneration and repair but much still needs to be learned about their biology, manipulation and safety before their full therapeutic potential can be achieved.

IT- 13 Photocatalysis for water treatment K.Y. Rajpure Electrochemical Materials Laboratory, Professor in Physics, Coordinator, SAIF, Head, USIC/ USIC-CFC Shivaji University, Kolhapur 416 004, Maharashtra, India www.rajpure.com [email protected]

Abstract: One of the most persistent problems bothering people worldwide is inadequate access to clean water. Over one billion people are exposed to unsafe drinking water due to poor source water quality and lack of adequate water treatment, a problem expected to grow worse in the coming decades. Photocatalysis is the acceleration of a photo-reaction in the presence of a catalyst. Heterogeneous photocatalysis involve the acceleration of photoreaction in presence of semiconductor photocatalyst; particularly metal oxides. This reaction could be degradation various organic species existing in water into relatively less toxic chemicals. It is based on the double aptitude of the photocatalyst to simultaneously adsorb both reactants and to absorb efficient photons. In mobile catalysis, there is difficulty in separating and recycling the catalyst and other few issues which needs to be addressed. Photoelectrocatalysis is the process wherein, in addition to illumination of radiation for photo-reaction, a separate electrical bias is applied between counter electrode and photo-catalyst (immobile) for effective improvement in IPCE of photoelectrochemical cell so formed due to impure water. TiO2 and ZnO are well studied catalysts for this purpose, which utilize the UV light due to their wide band gap energies. New catalysts, with appropriate band gap (e.g. Fe2O3, WO3), which would be useful for harnessing the visible part of light spectrum are been investigated. The focus is been to develop cost-effective visible light nano-composite thin films obeying the principles of green chemistry. Use of an efficient reactor for purification of domestic water using solar energy is revealed. The anti-bacterial activity of the reactor are also tested. It has been investigated that the reactor is effective in treating chemical and sugarcane factory wastewater and even the sea water. The underlying principles and the influence of the main parameters governing the kinetics are described. The current research activities that concentrate on the role of hydroxyl radicals in heterogeneous photocatalysis by transition metal oxides have been discussed.

Abstract: Globally, levels of air pollutions and releases of nutrients from agriculture and wastewater remain high, causing acidification and eutrophication in ecosystem, and losses in agriculture yield. Similarly, emission of toxic gases in to the environment poses severe pollution problem leading to global warming. In the coming decades, overall pollution levels are projected to increase strongly, particularly in Asia. Since the start of the industrial revolution in the 19th century environmental pollution has grown into a global transboundary problem that affects air, water, soil and ecosystem, and is linked to human health and well being. Nanomaterials and nanotechnology are being used in several applications to improve the environment. In trying to help our ailing environment, nanotechnology researchers are pursuing plethora of strategies. In this talk, I would like to put an emphasis on solar cells, supercapacitors and toxic gas sensors. These technologies help alleviate environmental pollutions problems, to some extent.

Abstract: In recent years, advanced material processing techniques have allowed scientists to research and document the properties of nanostructured metal oxides. One such material system, zinc oxide (ZnO), has emerged as a favorable option for a multitude of applications. In this study, thin films of ZnO with nanorod-like architectures were hydrothermally formed on a glass substrate and their physical and chemical properties were thoroughly characterized. X-ray diffraction confirmed the wurtzite structure and a scanning electron microscope was used to verify the vertical alignment of the rods. Defects due to the high oxygen vacancy concentration were revealed through photoluminescence studies. The high surface area of the nanorods works in conjunction with these defects and an optimal inter-rod spacing create conditions for effective gas adsorption and diffusion. With this in mind, the nanorods were used to fabricate a gas sensor which demonstrated excellent NO 2 sensitivity and selectivity at a relatively low operating temperature.

Abstract: Synthesis of Pectin-graft-poly(2-acrylamido-2-methylpropane sulfonic acid) gel was made in the form of beads by subjecting the solution containing pectin (Pec), 2-acrylamido-2-methylpropane sulfonic acid (AMPS) and ammonium peroxodisulphate (APS) to microwave irradiation followed by ionic crosslinking in CaCl2 solution. Silver nanoparticles containing gel beads were also prepared by the same method but with the addition of silver nitrate and trisodium citrate solution prior to microwave irradiation to obtain the nanocomposite gel beads. The synthesized Pectin-graft-poly(2-acrylamido-2-methylpropane sulfonic acid) gel (Pec-g-PAMPS) and the silver nanocomposite (Pec-g-PAMPS-SN) beads were characterized by FTIR, TGA, XRD, SEM and TEM techniques. The swelling and in vitro release experiments performed in pH 1.2 and 7.4 buffer media indicated significant pH responsive swelling in the gel samples. The in vitro drug release profiles of the parent gel and its composite were analyzed using dichlofenac sodium (DS) drug to study the effect of incorporation of Ag NPs on the drug release behavior of the Pec-g-PAMPS. The presence of silver nanoparticles enhanced both swelling of the gel beads and the extent of drug release significantly. The release process followed zero order kinetics and the mechanism of release was observed to change from non-Fickian to case–II transport on incorporation of nanoparticles in the gel sample.

Abstract: Polymer electrolytes are the subject of intensive study, in part because of their potential use as the electrolyte in all-solid-state rechargeable lithium batteries. These materials are formed by dissolving a Li 2SO4 salt in a solid host polymer such as poly (ethylene oxide), and be prepared by using solutions casting method. The structural properties were examined by XRD studies. The variation in film morphology is examined by scanning electron microscopy (SEM) micrographs indicated that the lithium salt particles were dispersed and embedded well within the polymer matrix. The absorption spectra were measured in the wave range from 200-800 nm at 303 K. The optical band gaps (Eg) for allowing direct transition decrease to increase the concentration of lithium sulfate. The optical activation energy was evaluated using Urbach-edges method. The thermal properties of these films were investigated by differential scanning calorimetry (DSC). The emission spectrum of the PEO emerged at 359 nm. The 50 wt% showed an emission peak at 384 nm, 25 nm red-shifts than that of the PEO. The rise of the conductivity is significant with increased concentration of Li2SO4; this is meant the decrease in the degree of crystalline and increase in the degree of crystalline and increase in the degree of amorphosity. This suggests that, Li2SO4 is a good dopant to improve the electrical properties, the maximum conductivity was found to be 2.25×105 S/cm.

Abstract: Al2O3 and ZnS-Al2O3 multilayers have been deposited on sapphire substrates using atomic layer deposition. The concentration of ZnS in ZnS-Al2O3 multilayers was varied to understand the effect of ZnS variations on the optical properties of the ALD deposited multilayers. The optical properties of ZnS-Al2O3 films were analyzed by using spectroscopic ellipsometry to evaluate optical parameters such as refractive index, extinction coefficient. To obtain more accurate optical constants the surface roughness effect was included in the model assuming Bruggman effective medium approximation (EMA). The simulation was conducted based on 4layer model (air/roughness layer/ZnS-Al2O3/sapphire). The conducted simulations on ellipsometric spectra for ZnS-Al2O3 multilayers using Forouhi Bloomer model and Bruggman effective medium approximation (EMA) revealed the best fit with low mean square error (2) value. In case of bare Al2O3 films, zero absorption was observed in wavelength range 400 nm to 800 nm, assures the use of this material as a transparent coating in optoelectronic devices.

Abstract: Encapsulation of small noble metal nanoparticles has received attention owing to the resulting highly increased stability and high catalytic activity and selectivity. In this study, we have developed a novel and facile synthesis strategy to construct the Rh/CeO2 nanostructures by a hydrothermal method. The structural insights of the obtained Rh/CeO2 nanostructure are investigated by various characterization techniques. Rh nanoparticles core encapsulated with a shell self-assembled by nanocubic CeO2, which has the advantages of low cost and high stability, and more importantly, the unique electronic configuration of ceria has a strong capability to provide active oxygen to the reforming reaction. The resulting Rh/CeO2 catalysts exhibit high catalytic activity and selectivity in the oxidative stream reforming of polyalcohol in microreactors, which reduce the heat and mass transfer limitations when operated under the conditions of the highly endothermic steam reforming reaction.

Abstract: Fluorescent pyrene nanoparticles (PyNPs) were prepared by a reprecipitation method for detection of fluorescein sodium (Fl-Na) in aqueous solution by fluorescence resonance energy transfer (FRET) approach. The formation of PyNPs was confirmed by dynamic light scattering (DLS), UV-visible absorption spectroscopy, fluorescence spectroscopy and excited state lifetime measurements. DLS results of PyNPs shows a narrow size distribution with average particle size of 77.4 nm and negative zeta potential. The systematic FRET experiments performed by measuring fluorescence quenching of PyNPs with successive addition of Fl-Na analyte exploited the use of PyNPs as nanoprobe for detection of Fl-Na in aqueous solution. The fluorescence of PyNPs was quenched by Fl-Na and quenching is in accordance with the Stern-Volmer relation. The Fl-Na and PyNPs were brought close enough, typically to 4.89 nm, which was less than the distance of 7 nm required for efficient FRET between the donor–acceptor molecules. The fluorescence quenching results were used further to develop an analytical method for estimation of Fl-Na from ophthalmic sample available commercially in the market.

For sample temperature variations the holder is inserted into a box furnace. A thermocouple based temperature measurement system meassures the furnace temperature and its integration with the temperature controller via the micro controller facilitated the required furnace heating in desired format by a suitable pre-set programmed heating cycle.The constant current arrangement employed in to function as a constant current source is derived from a set of SMPS power supply units which provide adequate emf required to push sufficient current through the high resistance film samples and generate measurable voltage across the voltage probe. For the maintenance of constant current,the variations occurring in circuit current were rectified by continuous monitoring and instantaneous corrections in supply voltage using a specially designed feedback circuit integrated on to the microcontroller. The current fed to the sample and the voltage generated across probes were gauged using calibrated sensors designed and fabricated with Texas instruments chopper amplifier based circuits. 20

Abstract: In optoelectronic devices, optical signal transmission gets more affected due to used materials and their properties. Here, vacuum evaporated magnesium oxide (MgO) thin films were studied for optical waveguide application by measuring their optical signal transmission loss (OSTL). Novel vapor chopping technique (VCT) was used to prepare vapor chopped (VC) MgO thin films and properties of those films were compared with as deposited or non-chopped (NC) films. Various oxidation temperatures (573, 623 and 673 K) and thin film thickness variation effect on the OSTL were studied. The VC MgO thin film waveguide showed a smaller transmission loss as compared to the NC MgO thin film waveguides. An AFM study showed that, surface roughness of VC thin films was lower than the NC MgO thin films and it increases with increase in oxidation temperatures. Keywords: Thin films, Oxide materials, Vapor deposition, Optical waveguide, Optical transmission loss.

Abstract: MnFe2O4 and CoFe2O4 magnetic nanoparticles (MNPs) were synthesized using simple polyol method by refluxing in diethylene glycol. The size of obtained CoFe2O4 MNPs was found to be 4.0 nm and MnFe2O4 MNPs was found to be 7.0 nm with surface area 291.04 M2/g and 165.39 M2/g respectively. These MNPs due to its high surface area and nanosize were used in the hemoglobin based biosensor for the detection of H2O2 as a mediator. The EIS measurements show that the CoFe2O4 MNPs are more conducting than the MnFe2O4 MNPs. The surface area of CoFe2O4 MNPs was found to be higher than the MnFe2O4 MNPs. The GCE/CS/CoFe2O4/Hb modified biosensor shows wider linearity range (1×10-7 to 8×10-4 M) than the GCE/CS/MnFe2O4/Hb modified biosensor (1×10-6 to 4×10-4 M) because of higher conductivity and greater surface area of CoFe 2O4 which increases the catalytic activity.

Abstract: A number of automakers and battery companies have been focussing on the development of hard carbon for use in electric vehicles, mainly motivated by its high reversible capacity. Recently, anode capacity between 200 and 600 mAh/g has been reported. This high capacity is associated to the material porous nature, number of graphene sheets and surface area. Titanium based oxides have drawn significant attention in the lithium battery community because they allow the designing of operational devices with minor safety concerns. Moreover, this class of active materials shows other interesting features such as inexpensiveness, low toxicity, low volume change (2–3%) on both lithium insertion and de-insertion, along with an excellent cycling life. Researchers at North Carolina State University have demonstrated the use of silicon coated carbon nanotubes for in anodes for lithium-ion batteries. They are predicting that the use of silicon can increase the capacity of lithium-ion batteries by up to 10 times.

Abstract: Solar energy is commonly seen as a clean energy source and an alternative to the fossil fuels. Considering the growing use of solar cells, the problem of recycling spent solar cells, whose quantities will increase rapidly in the coming years is yet to be solved. Establishing a technology for recycling the same is thus a necessity. They contain many precious and hazardous metals. Limited recycling will result in disposal of these recoverable metals in the waste. This paper presents the eco-friendly method for recovery of valuable metals like Te from spent solar cells. The recovery of metals from solar cells was investigated using culture supernatant of Acidithiobacillusferrooxidans. B, Mg, Si, Ni and Zn were removed with 100% efficiency within a reasonable time. Further optimization of process parameters resulted in nearly 95% recovery of valuable metal Te at 20 °C, 50 rpm and 1% pulp density. The recovered Te from this process can be further purified according to its future use. The possible success in this endeavor will allow reuse of waste solar cells without affecting the environment.

Abstract: Magnesium-doped ZnO (MZO) nanoparticles were synthesized by simple chemical co precipitation method by using zinc acetate (Zn (CH3COO)2·2H2O) and magnesium acetate Mg (C2H3O2)2. Ammonium hydroxide was used to precipitate Zn2+ and Mg2+ cations simultaneously. Crystallization of MZO was investigated by X-ray diffraction (XRD) technique. X-ray diffraction analysis reveals that the MZO crystallizes in a wurtzite structure. Also XRD studies point toward a significant c-axis compression and reduced crystallite sizes for MZO samples in contrast to undoped ZnO. Textural properties of these MZO samples obtained at various calcination temperatures were superior in comparison to the undoped ZnO. The microstructural features shows nanopaticles are self-aggregated themselves into depressed spheres. The formation of depressed spheres indicates the Mg2+ is successfully substituted into the ZnO host structure of the Zn2+ site. Keywords: Co-precipitation, Mg doping; zinc oxide; Microstructure.

Abstract: This work considers classical problem of surface-groundwater interaction between a sloping aquifer and a rising water stream in the presence of a thin clogging sedimentary layer. The mathematical model uses nonlinear Boussinesq equation subjected to nonlinear Robin boundary condition. Closed form analytical solution is derived for estimate the water table in the aquifer. The solution is represented in such a manner that the several other configurations such as zero slope, absence of clogging layer and abrupt change in stream-stage can be deduced as limiting case of main result. Advantages of using a nonlinear Robin boundary condition and combined effects of aquifer parameters on the bank storage characteristic of the aquifer are illustrated with a numerical example.

Abstract Gallium nitride is a wide band gap semiconductor material. Gallium nitride has find potential application in optoelectronic devices. The low energy ion implantation of semiconductor is one of the most important methods of surface modification. The negative ion implantation technique remarkably improve the charging problem since the incoming negative charge of implanted negative ions is easily balanced by the outgoing negative charge of a part of secondary electrons [1]. In the present work, Gallium nitride film grown on sapphire substrate samples were implanted with 100 keV Si-1 ions for ion fluence 5 x 1015 and 5 x 1016 cm-2 at room temperature using the SNICS ion source at Low Energy Ion Beam Facility (LEIBF) at Inter University Accelerator Centre (IUAC), New Delhi. Atomic force microscopy, X-ray diffraction, Raman spectroscopy and UV-Vis spectroscopy techniques have been used to study the effects of silicon negative ions in gallium phosphide. AFM studies showed the presence of nanostructure on the surface of silicon implanted gallium nitride Keywords: Ion implantation; Silicon negative; Gallium phosphide; AFM

Abstract : In present study, nickel oxide (NiO) nanoplatelets (NPs) were synthesized by a simple, cost-effective, eco-friendly and low-temperature successive ionic layer adsorption and desorption method, annealed for 300 °C for 1h, scratched from the supporting substrate i.e. glass and envisaged for the antimycobacterial, antioxidant and cytotoxic activity studies. The structural investigation of synthesized NiO NPs was carried out with the help of X-ray diffraction (XRD) and Raman shift spectra. Reflection planes i.e. (111), (200), (220), and (311), obtained from the interatomic spacing based on individual the ring diameter, of selected area electron diffraction (SAED) pattern and Raman shift peaks at 550 cm -1 and 1095 cm-1, which were due to the one and two phonon longitudinal optical modes of Ni-O oscillation, corroborated for the XRD analysis i.e. NiO formation. Platelets-type morphology of NiO was corroborated from the FESEM and TEM measurements. From BET analysis, poresize and surface area assigned to these platelets were 33.56 nm and 57.84 m 2/g, respectively. The grain size of an individual nanoplate was 4-8 nm. NiO NPs demonstrated a dose-dependent cytotoxicity against the human blood cells, once exposed to a microbial activity measurement. The inhibitory concentration was found to be 10 µg/ml for NiO NPs against the human blood cells; biofilm formation by M. tuberculosis (MTCC-300) and M. pheli (MTCC-1723). Only 0–95% hemolysis response was obtained for 10 µg/ml tested concentration while Rifampicin showed 100% haemolysis activity at 10 µg/ml. Competitive 63.44% for NiO NPs over 88.23% for standard i.e. di(phenyl)—(2, 4, 6-trinitrophenyl) iminoazaniun antioxidant performance through in-vitro antioxidant assays was recorded. Antimycobacterial assay results suggested that inorganic NiO NPs can be a potential material against two Mycobacterium species and an open new avenue for nanostructures of other metal oxides/chalcogenides.

Abstract: A simple rectangular photoreactor of 10-L capacity was fabricated in glass plates. The performance of the reactor in the degradation of Orange M2R dye was evaluated under sunlight with ZnO as a photocatalyst. The Orange M2R dye was selected in the study as it is used for cotton dying. Analytical reagent grade ZnO was used as photocatalyst as it displayed higher photocatalytic activity than synthesized ZnO. The degradation study of dyes was performed under sunlight. Different parameters that influence the degradation of the dye in the reactor were optimised. The pH of the dye solution, catalyst dose, and height of the dye solution in the reactor were identified as crucial experimental parameters affecting the dye degradation. The pseudo first-order decolourisation rate constant under optimised reaction conditions was evaluated by applying the Langmuir– Hinshelwood equation. Chemical oxygen demand measurement revealed that at the decolourisation stage complete mineralisation of the dye does not take place. Furthermore, a flat slurry reactor-based process was found effective for the degradation of dyes from the actual effluent. Keywords: photoreactor, OM2R, dye effluent, degradation, ZnO Photocatalyst

Abstract: Electronic waste is the most rapidly growing problem across the globe. Though the statistics portrays an enormous increase in e- waste, the amortization of electrical and electronic equipment (EEE) in market is relatively high. The Basel Convention has warned of serious environmental repercussion if it is continued to be disposed off in an unscientific manner. Besides there are risks to women and child labourers who are involved in sizable number in illegal recycling of e-waste. ICP-OES abbreviated for Inductively coupled plasma optical emission spectroscopy is a highly sensitive technique used to analyse multiple elements in ppm concentration with highest accuracy in minimum time. ICP-OES is based on the principle of plasma energy which excites the element at 10000 K temperature which further emits rays while returning to low energy position. In current study, 0.5 mm fraction of PCB of mobile phones was analysed for its elemental composition using ICP. The study revealed the presence of base metals Co< Mg< Pb < Zn < Ni < Al
