Abstract:

Sustainability and environmental safety management involves managing the natural resources optimally and with minimal impact on environment. Human-induced climate change has become a major focus of scientific research because of the potential catastrophic effects on biodiversity, food security and human communities. As a consequence corporate spending on environmental health and safety is increasing. A marked effect of climate change on the global scale demand more intervention of environmental biotechnology and green chemistry to understand the issues at micro-level. The formulation of adaptive strategies together with assessment of the impact of climate change forms the base for climate resilient agriculture globally. With this the cropping pattern of rice growing areas has changed and after harvest a large volume of rice plant residue is left behind which has limited use. This plant residue is rich in enzymes which remains untapped. The present work showcases the use of a plant residue for the development of a dopamine sensor for use of human subjects as a sustainable approach towards management of neurological patients without compromising with the food supply or nature at large.

Abstract:

Curcumin is a well-known anti-inflammatory and antioxidant agent that significantly reduces the nicotine-induced toxicity both at cellular and genetic levels. However, the poor aqueous solubility of curcumin makes it less bio-available that hinders the more possible remediation of curcumin against nicotinic abuse in the target cells. An attempt was made to synthesize nano-curcumin (20-50 nm) that would be more soluble in water with enhanced bioavailability. The prepared nanoparticles of curcumin (Cur-NPs) were characterized by ultraviolet-visible (UV-Vis) spectroscopy, field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) and Zetasizer techniques. Investigations were performed on the structural modifications of nicotine-triggered two important mammalian proteins (α-lactalbumin: α-LA and Cytochrome-c: Cyt-c) via the interaction of concentration dependent curcumin nanoparticles. It was observed that nicotine significantly affected the structural conformation and optical properties of α-LA and Cyt-c proteins by modifying their structural integrity. Cur-NPs significantly regained the structural integrity of those nicotine-treated proteins as reveled by the results from UV-Visible absorption, intrinsic fluorescence emission and circular dichroism (CD) studies. The isothermal titration calorimetric (ITC) investigation demonstrated that Cur-NPs prevented the nicotine molecules for binding in the active site of those proteins. This was due to the greater binding affinity of curcumin towards α-lactalbumin (-4.87 KCal/mol) and Cytochrome c (-7.64 KCal/mol) proteins in comparisons to nicotine (-4.24 KCal/mol; ~ -5.26 Kcal /mol respectively) as observed in molecular docking studies. This study clearly demonstrated that curcumin in its nano particulate form acted as an efficient ameliorative against nicotine-induced toxicity at cellular levels.

Abstract:

Quantum dots (QDs) are spherical or close spherical nanoparticles often consisting of elements from groups II–VI or III–V of the periodic table. Their grain diameter is general less than 10 nm. They have many advantages over traditional organic dyes, such as high quantum yield, good photochemical stability and high photobleaching threshold. Recently, QDs as a new kind of fluorescence probe for small molecular compound, biomacromolecule and heavy metal iron have interested analytical workers. Fluorescence quenching of QDs is often used in common application. In our study, water-soluble CdTe QDs were synthesized with TGA as a modifying agent in aqueous solution. Based on the quenching effect of carbazochrome sodium sulfonate on the fluorescence of CdTe quantum dots, a new method for determination of carbazochrome sodium sulfonate was developed with CdTe quantum dots as a fluorescence probe. Under the optimal condition, fluorescence quenching of CdTe QDs had a good liner with concentration of carbazochrome sodium sulfonate, in the concentration range of 1~12 ug/ml. The equation was: ln(F₀/F)=44.577-0.0139C, R²=0.9999. The detection limit is 0.67 ug/ml. Average recovery was 100.1%. In this paper, water-soluble CdTe QDs were synthesized and capped with TGA by using a simple method. Reaction between QDs and carbazochrome sodium sulfonate was studied. A new method based on the fluorescence quenching of CdTe QDs was developed for carbazochrome sodium sulfonate determination. All experimental data indicated that this method was simple, rapid and exact.

Abstract:

Chinese rice wine sensory attributes including color, aroma, taste and style play a major role in product acceptability by directly influencing the success of a product in the marketplace. The estimation of the sensory attributes is generally done by human sensory analysis. However, the use of human for sensory evaluation entails several drawbacks, such as fatigue, stress and inconsistence etc. This study aimed to assess the feasibility of using near infrared (NIR) spectroscopy technique as an instrumental evaluation technique for predicting the sensory attributes (i.e., color, aroma, taste and style) in Chinese rice wine. Synergy interval partial least squares (si-PLS) was used to select the optimal spectral intervals and construct models between the NIR spectra and the reference scores of each sensory attribute, respectively. The performance of model was evaluated by the correlation coefficient (Rp) and the root mean square error (RMSEP) in the prediction set. The optimal performance by the si-PLS model for color was Rp=0.8735, RMSEP=0.274; the aroma was Rp=0.8316, RMSEP=0.893; the taste was Rp=0.8791, RMSEP=1.22; and the style was Rp=0.7784, RMSEP=0.557. This work demonstrated that the instrumental test using NIR spectroscopy technique has a high potential in predicting the sensory attributes in Chinese rice wine; it can overcome the drawbacks of human sensory analysis and achieve the objective measurements in a short time in a consistent and cost-effective manner.

Abstract:

Green chemistry, also called sustainable technology, is a major challenge in industry and research. In fact, there is a growing need for more environmentally acceptable processes in the chemical industry. Industrial vegetable by-products contain high levels of valuable phytochemicals that can be use as a great source of biomolecules. The main objective of this project was to develop a sustainable, safe and ecological process, to extract and separate lutein and chlorophyll from spinach by-products respecting the main principles of green chemistry. A saponification in an aqueous medium was carried out in order to hydroxylate the ester bond of the aliphatic chain of chlorophyll. Polar chlorophyll derivatives were thus formed, remaining in the aqueous medium. Lutein, remaining apolar, stayed in the residue and was finally extracted by maceration in 95% ethanol. However, the saponification step was responsible of a significant degradation of lutein. This last stage of separation was consequently studies through response surface methodology in order to determine which saponification parameters gave the highest recovery of lutein in the final ethanolic extract with the lowest amount of chlorophyll. Through this procedure, using the Derringer’s desirability function, the optimal conditions for separation were 16 h of saponification, at 20°C and with 17.2% of sodium hydroxide. This procedure can be streamlined in a commercial extraction process for these compounds.

Abstract:

Glucose biofuel cells are considered a promising power supply with a competent long-term stability and power density. In this respect, novel modified electrodes were fabricated for biofuel cell based on electrochemical polymerization of organic monomer on glassy carbon electrodes. An investigation was carried out on the catalytic electrooxidation of glucose in alkaline media utilizing conducting polymer electrodes modified by incorporation of palladium-nanoparticles (PdNPs) and platinum-nanoparticles (PtNPs) onto poly(1,8-aminonaphthalene) (1,8-PDAN). SEM and EDX analysis depict the homogenous distribution of the metal nanoparticles onto the polymer film. The prepared Pd/PDAN/GC, Pt/PDAN/GC and Pt-Pd/PDAN/GC modified electrodes showed an excellent electro-analytical performance with excellent operation/storage stability. The voltage response exhibited a linear relationship with increase in glucose concentration (2.0 μM to 25.0 mM), with a sensitivity of 160 μA/mM/cm². Higher activity and stability of Pt-Pd/PDAN/GC composite electrode were observed. These versatile kind of modified electrodes render the potential candidates for developing a new generation of glucose biofuel cells.

Abstract:

The development of rapid method for green synthesis of nanomaterials is day by day becoming popular among nanotechnologists. In the present study the author has reported synthesis of silver nanoparticles at room temperature using N. tabacum leaf extract. The synthesized nanoparticles have been found to be stable for several months. UV-Visible spectroscopic analysis carried out revealed the formation of silver nanoparticles in reaction mixture. Similarly, the X-ray diffraction analysis confirmed the formation of silver nanoparticles. SEM and TEM imaging unveiled the structural morphology of synthesized nanoparticles to be spherical, non-uniform and polydispersed. EDX analysis of nanoparticles indicated the presence of elemental silver. The synthesized nanoparticle is multi-applicative and showing potential activity against gram negative bacterium Salmonella typhimurium. Synthesized AgNPs can be used for variety of applications such as antifungal, wound healing, textile nanocoating, efficient catalyst for organic transformation and dye degradation, etc. In near future, silver nanoparticles synthesized using green methods may be used in the treatment of infections caused by highly antibiotic resistant microorganisms. The main mechanism considered for green synthesis is plant assisted reduction due to presence of phytochemicals. The major phytochemicals involved are terpenoids, flavones, ketones, aldehydes, amides and carboxylic acids. Flavones, organic acids and quinones are water soluble phytochemicals that are responsible for the immediate reduction of the ions. Studies have revealed that xerophytes contain emodin, an anthroquinone that undergoes tautomerization, leading to formation of the silver nanoparticles. The major mechanism involved is phytochemical assisted reduction of the ions.

Abstract:

Enzymes are preferred over chemical catalyst for the synthesis of various chemicals as it requires mild reactions conditions. Additionally since enzyme catalyzed processes do not generate any waste material due to high selectivity of enzyme; the process can be labelled as “green process”. This work deals with synthesis of cinnamyl adipate by esterification between cinnamyl alcohol and adipic acid catalyzed by immobilized lipase B from Candida antarctica, commercially known as Novozym 435 in a conventional batch reactor using standard mechanical mixing and in solvent free system. Effects of various parameters such as nature of lipase, speed of agitation, mole ratio, catalyst loading, temperature and reusability of catalyst on the conversion was studied and optimized. Overall conversion of 94.05% was achieved at optimized conditions as reaction time of 12 h, mole ratio of adipic acid to cinnamyl alcohol of 1:3, catalyst loading 1% and reaction temperature of 60°C. It is also observed that the enzyme can be recycled seven times without marginal loss of enzyme activity. To the best of our knowledge, this is first report where enzyme is used as a catalyst for synthesis of cinnamyl adipate. From the progress curve analysis, it was established that the reaction followed the random bi-bi mechanism. There was an excellent agreement between the experimental data and stimulated data. This work will be very useful for synthesis of cinnamyl adipate and many other such chemicals via green route as well as design of batch rector.

Abstract:

Microbial fuel cells (MFC) are in the focus of interest for last few decades as an alternative source of electricity generation. These bio-electrochemical systems depends on bacterial metabolism of a variety of organic substrates [1]. The electricity generation in MFC mainly depends upon the microbial electrogenicity. Mixed cultures have been reported to generate greater power using specific compounds or organic matter in wastewater and marine sediment in mediator-less MFCs [2]. In the present study, Pseudomonas sp. BT 302 (NCBI Acc. No.JQ782891) and Comamonas sp. BT UA (NCBI Acc. No.GU265556) were used for utilization of uric acid and generation of electricity. Poultry waste soil contains mainly uric acid along with crude protein, crude fibre, calcium, phosphorous etc. Synthetic media with uric acid were prepared as prototype of poultry waste soil and MFC was constructed in a dual-chamber continuous flow design. Three sets of experiments were continuously run with BT UA pure culture, BT 302 pure culture and both microbes mixed culture for comparative study with respect to power generation. Current generation, cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) were recorded for investigating the anode-biofilm electron transfer behaviour. Total organic carbon (TOC) was determined to evaluate the feasibility of substrate utilization by bacterial strains. The continuous input flow of fresh media and subsequent discard of waste helped to maintain the bacterial growth at equilibrium (average O.D.600 = 1.879 ± 0.095). Microbes were found acclimatized in the fuel cell within 15-18 h having an average CFU of 2×1012 for M-1, 2.16×1014 for M-2 and 1.51×1016 for M-3. Within this time interval the open circuit voltage (OCV) reached a maximum of 582mV for mixed microbes. After 7 days, utilization of substrate resulted in low uric acid, much higher allantoin and highest amount of urea in the waste soup of MFC. The maximum current density and power density were found to be 78.12 mA m-2 and 13.65mW m-2 respectively for mixed culture with the total anodic volume of 1liter against external load of 10kΩ. The optimal external resistance was found to be 806Ω for all three sets. A uric acid-MFC was successful in achieving moderate cell efficiency and continuous power generation. This continuous flow fuel cell would have potential application in power generation and valuable by-product formation through green route.

Abstract:

Introduction: Magnetic resonance imaging have been used nowadays as one of the accepted tool for diagnosis, estimation, and evaluation of many of human diseases; in dentistry, many of prosthodontics patients and "maxillofacial-prosthesis" patients may fall under the category who might be subjected to routine MRI check-up either for follow-up of certain disease or cancer patient for determining the degree of healing or metastasis; thus, there has been growing interest in the research of the possible effect of MRI procedure on different component of dental appliances worn by the patients and one of these components is heat cured acrylic resin.

Aim: The aim of this study is to evaluate the effects of magnetic resonance imaging on mechanical (tensile strength, hardness) physical (color change) chemical (FTIR, NMR) properties at different periods of time exposure.

Materials & Methods: In this study, total 454 samples were prepared from acrylic based heat cured denture material, which were divided into two main groups clear and pink. Each main group was subdivide into 4 groups according to the exposure to MRI control; (5,15 ,30) minute each of the 4 sub-groups underwent different tests like tensile strength, hardness (Rockwell) test, dimensional accuracy test, color change by spectrophotometer, surface roughness, water sorption, residual monomer release by FTIR and NMR.

Results: The results were analyzed by descriptive analysis, analysis of variance, Duncan's multiple range tests and student’s t-test. The results showed that there were changes in the physical properties of heat cured acrylic resin weather it is in pink or clear after exposure to MRI and these changes happened at different levels and variable degrees. It was also shown that there was a slight tendency to change order of arrangement of atoms within each molecular with no well and clear evidence of chemically altering of the main material itself, at least, at circumstances of experiment.

Abstract:

The synthesis of new conjugated electroluminescent polyquinoline derivative Poly (2,2-(p-phenyl)-6,6-bis(4-phenylquinoline) [PPPQ], which are soluble in organic solvents and its incorporation in light-emitting diodes as the emissive layer are reported. These electroluminescent devices, containing 1, 1-bis (di-4-tolylaminopphenyl) cyclohexane (TAPC) dispersed in polystyrene as the hole-transport layer, emit bright yellow light (λ_max=554 nm) with quantum efficiency of 0.26% photons/electron and a luminance of 280 cd/m² at a current density of 100 mA/cm². Electroluminescence of moderate brightness was achieved with blue-green, green, yellow, orange, and deep red colors depending on the arylene linkage of the copolymer. The thermal, electrochemical, photophysical, and electroluminescent properties of new polyquinolines varied with the arylene linkage, including p-phenylene, 4, 4-biphenylene, 5, 5-bithienylene. These results also demonstrate that the new polyquinoline is a good electron transport electroluminescent material. Large enhancement in electroluminescence efficiency and brightness of light-emitting diodes fabricated from binary blends of conjugated polyquinolines was observed compared to devices made from the homopolymers. The polymers have thermal properties with glass transitions temperature of 161-339^â—¦C. The electrical properties of the diodes and electric field modulated photoluminescence spectroscopy results confirmed that the enhancement of electroluminescence in the blends originated from spatial confinement of excitons which leads to increased exciton stability and electron hole recombination efficiency. Voltage tunable and composition –tunable multicolor electroluminescence was observed in the polymer blend devices. The observed composition dependent new emission bands and enhanced fluorescence lifetimes in the blends were suggested to originate from exciplex formation and molecular miscibility between the blend components. These results demonstrate new phenomena in the electroluminescence and photophysics of multicomponent conjugated polymers.

Abstract:

Industrial chemical products and machinery are part of the technology that is causing major environmental problem. Their assessment at all stages, from raw materials acquisition, to manufacture and disposal need to be evaluated and quantified. For a holistic approach of the subject scientists established the scientific method called Life Cycle Analysis (LCA). LCA is also known as life-cycle eco-balance. It is a technique to assess environmental impacts associated with all the stages of a product's life, from-cradle-to-grave (i.e., from raw material extraction, manufacture, distribution, use, repair, disposal or recycling). The process of LCA of a product is a systematic process which takes into account all the stages in the making of a product. It starts from the raw materials, the step by step industrial processes, the useful life as a consumer product and its final stages through maintenance, recycling or disposal. The LCA process is a systematic, phased approach and consists of four components: goal definition and scoping, inventory analysis, impact assessment, and interpretation of the results. Herein, we will attempt to give insights into the currently Role of green chemistry in life cycle analysis of industrial products as a systematic process and summarize the resulting findings in this area, emphasizing on components of this process.

Abstract:

Metals play an important role as catalyst in organic synthesis and have been instrumental in many key transformations. Several noble and expensive metals such as platinum, gold, silver and palladium have been demonstrated to catalyze many important reactions. However, for better cost management and environmental concern use of less expensive and more environment friendly metals is desirable. Thus, the main focus of our group’s activity is directed to benign and inexpensive metal catalyzed C-C and carbon-heteroatom bond formation leading to the synthesis of bioactive molecules. For example, we have developed a recyclable heterogeneous catalyst of Cu(II) anchored on Al2O3 surface, that has been successfully used for several reactions. One of them is Cu(II)/Al2O3 catalyzed solvent controlled selective N-arylation of cyclic amides and amines leading to important scaffolds of potent therapeutic agents (Chem-Euro J., 2013, 19, 15759). We have also developed a novel concept of using two appropriate inexpensive metals in place of expensive metal like palladium and ligand, where one metal takes active part in catalysis and other one is assisting the process. Using this protocol copper-assisted nickel catalyzed ligand free Csp-Csp and Csp-Csp2 cross-coupling providing a direct access to unsymmetrical 1,3-diynes and en-ynes (Chem. Commun. 2014, 50, 15784), and Co/Cu catalyzed C(sp2)-O cross-coupling (Chem-Euro J. 2015, 21, 8727) have been achieved among others, Our another approach is to design metal free reaction which is traditionally mediated by metals. Thus, we have developed a visible light photocatalyzed direct conversion of aryl/heteroaryl amines to selenides at room temperature ( Org. Lett., 2014, 16, 1814)

Metal-organic frameworks (MOFs) are exciting class of materials which showed their potential in variety of applications such as gas adsorption, magnetism, catalysis etc. We are trying to explore the possibilities of converting as synthesized MOFs towards energy conversion materials. A variety of porous carbon (PC) samples were prepared by direct carbonization of variety of porous metal-organic frameworks at various temperatures under inert atmosphere. The synthesized carbon materials were checked for super capacitive behavior. Furthermore high surface area PC was deposited with PtM (M = Fe, Ni, Co and Cu (20%) metal loading) nanoparticles by using polyol reduction method and different catalysts were designed for direct ethanol and methanol fuel cell (DEFC) applications. The results showed that PtFe/PC catalyst combination exhibited superior performance amongst the other options. The electrocatlytic capability of the catalyst for ethanol electroxidation was investigated using cyclic voltammetry, and direct ethanol single cell testing. The results were compared with that of Pt-Fe and Pt supported on Vulcan XC 72 carbon catalysts (Pt-Fe/XC-72 and Pt/XC-72) prepared via same method. The catalyst PtFe/PC developed in this work showed outstanding normalized activity per gram of Pt (6.8 mA/gPt) and superior power density (121 mW/cm2 at 90 °C) compared to commercially available carbon supported catalysts. The current work is in progress for the testing of other cheap metal combinations. The new field has attractive position in the field of fuel cell applications.

Abstract:

Corrosion has been a perennial issue of concern for the manufacturing industry. Chromate (VI) conversion coatings are well known pre-treatment coatings for steel but due to environmental concerns and legislations, their use and application has been restricted. This has led to a growing demand and need for an economically viable and eco-friendly pre-treatment coating. Graphene based anti corrosion coatings have been developed which can provide an eco-friendly alternative while also improving the overall performance of the coating system. Energy and Environment are key areas of technology for many Tata Group companies such as Tata Steel. Coating plays a vital role in improving surface quality and providing protection for the metal substrates. Graphene, a newly discovered carbon allotrope, received worldwide attention due to its exceptional properties owing to its unique structure. It is a very promising new generation of material that can trigger the fabrication of advanced coatings with much different functionality. In this work, utilization of graphene in advanced coatings for metal, Tata patented technology will be presented giving emphasis on the corrosion protection. A corrosion inhibitive coating composition was developed for metal substrate, which comprises monolayer and multi-layer graphene stacks and a coupling agent consists of an organo functional siloxane. Durability performance were studied this Cr(VI) free system against the commercially available system using electrochemical and accelerated corrosion testing. The future perspectives of graphene based coatings for industrial application and the importance with academics collaborations on specific areas of graphene research will be briefly discussed.

Abstract:

The talk will concentrate on various approaches being used to engineer materials at the nanoscale for various applications in future technologies. In particular, the case of clay, carbon nanostructures (e.g. nanotubes, graphene), metal oxides, bionanomaterials (cellulose, starch and chitin) will be used to highlight the challenges and progress. Several polymer systems will be considered such as rubbers, thermoplastics, thermoetts and their blends for the fabrication of functional polymer nanocomposites. The interfacial activity of nanomaterials in compatibilising binary polymer blends will also be discussed. Various self assembled architectures of hybrid nanostructures can be made using relatively simple processes. Some of these structures offer excellent opportunity to probe novel nanoscale behavior and can impart unusual macroscopic end properties. I will talk about various applications of these materials, taking into account their multifunctional properties. Some of the promising applications of clay, metal oxides, nano cellulose, chitin, carbon nanomaterials and their hybrids will be reviewed.

Abstract:

Glucose biofuel cells are considered a promising power supply with a competent long-term stability and power density. In this respect, novel modified electrodes were fabricated for biofuel cell based on electrochemical polymerization of organic monomer on glassy carbon electrodes. An investigation was carried out on the catalytic electrooxidation of glucose in alkaline media utilizing conducting polymer electrodes modified by incorporation of palladium-nanoparticles (PdNPs) and platinum-nanoparticles (PtNPs) onto poly(1,8-aminonaphthalene) (1,8-PDAN). SEM and EDX analysis depict the homogenous distribution of the metal nanoparticles onto the polymer film. The prepared Pd/PDAN/GC, Pt/PDAN/GC and Pt-Pd/PDAN/GC modified electrodes showed an excellent electroanalytical performance with an excellent operation/storage stability. The voltage response exhibited a linear relationship with increase in glucose concentration (2.0μM to 25.0mM), with a sensitivity of 160 μA/mM/cm2. Higher activity and stability of Pt-Pd/PDAN/GC composite electrode were observed. These versatile kind of modified electrodes render the potential candidates for developing a new generation of glucose biofuel cells.

Abstract:

The development of rapid method for green synthesis of nanomaterials is day by day becoming popular among nanotechnologists. In the present study the author has reported synthesis of silver nanoparticles at room temperature using N. Tabacum leaf extract. The synthesized nanoparticles have been found to be stable for several months. UV- Visible spectroscopic analysis carried out revealed the formation of silver nanoparticles in reaction mixture. Similarly, the X-ray diffraction analysis confirmed the formation of silver nanoparticles. SEM, and TEM imaging unveiled the structural morphology of synthesised nanoparticles to be spherical, non-uniform, and polydispersed. EDX analysis of nanoparticles indicated the presence of elemental silver. The synthesized nanoparticle is multi-applicative and showing potential activity against gram negative bacterium Salmonella typhimorium. Synthesized AgNPs can be used for variety of applications such as Antifungal, Wound Healing, Textile Nanocoating, efficient catalyst for organic transformation and dye degradation etc. In near future, silver nanoparticles synthesized using green methods may be used in treatment of infections caused by highly antibiotic resistant microorganisms. The main mechanism considered for green synthesis is plant assisted reduction due to presence of phytochemicals. The major phytochemicals involved are terpenoids, flavones, ketones, aldehydes, amides and carboxylic acids. Flavones, organic acids and quinones are water soluble phytochemicals that are responsible for the immediate reduction of the ions. Studies have revealed that xerophytes contain emodin, an anthroquinone that undergoes tautomerization, leading to formation of the silver nanoparticles. The major mechanism involved is phyto-chemical assisted reduction of the ions.

Abstract:

Three different deep eutectic solvents (DESs) synthesized from ammonium salts are employed as electrolytes for an H-type redox battery using vanadium acetylacetonate [V(acac)3] as the electro-active species. Preliminary investigation show that the highest solubility of [V(acac)3] is in a DES made from choline chloride and ethylene glycol (ethaline). Cyclic voltammetry indicate that ethaline is stable in an operating potential range of -1.8 to +1 V. The diffusion coefficients of V(acac)3 in the electrolyte has been estimated to 0.69 cm2s-1 at room temperature. Charge/discharge performance using the static H-type electrochemical cell gives coulombic efficiencies near 50%. In comparison to results obtained with acetonitrile as a solvent, the DES seems to show similar performance (despite being cycled at least 12 times). This is encouraging because DES is safer to work with and significantly more environment friendly than acetonitrile.

Abstract:

According to the WHO, pure natural drinking waters, are scarce (less than 2% in nature). Water is contaminated with different hazards, including organic compounds (dyes, phenol derivatives, chlorinated hydrocarbons, industrial dyes, pharmaceutical wastes, humic acid, etc.) and microorganisms (bacteria). Small and large-scale purification techniques, such as chlorination, ozonation, hydrogen peroxide oxidation, reverse osmosis, UV irradiation, etc, are used. Such processes are effective, but costly, and not available to many third world countries. Chlorination produces chlorinated hydrocarbons in the municipality sewage. Advanced Oxidation Processes (AOP) which involve oxidation of contaminants by solar radiation are promising alternative. AOPs rely on the safe stable low cost TiO2 and ZnO nano-particle, as catalysts in photo-degradation of contaminants. Such materials have large wide bad gap values (~3.2 eV, 387 nm) and demand UV radiations to function. In this plenary, the feasibility of using TiO2 and ZnO nano-particles in complete mineralization of organic contaminants will be assessed. Ongoing activities to sensitize TiO2 and ZnO to visible solar light (main part of solar light), with synthetic dyes or quantum dots, will be critically assessed. Using natural dye sensitizers, as safe alternatives, will also be highlighted. Complete mineralization of organic contaminants with natural-dye sensitized photo-catalysts will be discussed. Ability of the sensitized particles to completely mineralize gram negative bacteria, and the organic matters that result from their death, will also be presented for the first time. Feasibility of using these safe practices at large scale will be assessed.
