Abstract

This project entitled, “Development of nanocrystalline materials for solid oxide fuel cells working at 600o C” aims to develop alternate electrolyte, cathode and anode materials from nanoceramics with improved specific functional characteristics in order to reduce the operating temperature of SOFC from 1000o C to about 600o C (low temperature range). In order to reduce the cathode polarization loss, a novel strategy of using nanocrystalline cathodes with composition Ln1-xSrxCo1-yFeyO3-δ (where Ln = Nd or Gd; x=0.05, 0.10, 0.15 &0.20 and y = 0.05, 0.10, 0.15 and 0.20) is prepared. The anode performance is improved by adopting nano-structured composite material based on NiO - Ce1-xNdxO2-δ - Ce1-yGdyO2-δ (where x = 0.05, 0.10, 0.15, 0.20 and y = 0.05, 0.10, 0.15, 0.20).

Abstract

The development of metal functionalized carbazole and fluorene are challenging task for advancing the research progress in this emerging field of opto electronic applications. Because, metal-organic dyes have their unique advantage, the dye including metal is easier to capture electron and slow electron–hole recombination, good thermal stability, processibility, so it is easier to promote its solar-to-electricity conversion efficiency. Moreover, the dyes with strong absorption in the near-infrared (NIR) region have received increasing attention in the past decades owing to their potential applications including NIR light-emitting diodes, biosensing, photovoltaic cells, and telecommunication. The introduction of both donor and acceptor substituents into the parent chromosphere with π-electron delocalization leads to charge transfer (CT) absorption band in the NIR region, which is a simple but promising strategy to achieve NIR absorbing dyes. In this context, metal dithiolene complexes are promising dyes, which gives rise to a strong absorption in the near-IR region, but inadequately explored. Further, metal dithiolene complexes form a well-known class of compounds whose peculiar electronic structures determine their conducting, magnetic, and optical properties. Envisions, metal-dithiolene-carbazole and fluorene based planar and π-extended dyes could exhibit the prompt change in the structure, electrical, optical and conducting properties with respect to metal oxidation state. Where, the electron donor part is represented by the carbazole or/and fluorene units and electron acceptor part is represented by metal -dithiolene unit, thereby, HOMO-LUMO energy levels minimization will occur, which lead the absorpton to longer wavelength. So, it should be possible to achieve NIR absorbing optoelectronic materials through tuning electron donor moieties, metal oxidation state and extended π-conjugation.

Abstract

In this project, we have synthesized and characterized the different type of Non-haem Based mono and bimetallic complexes of transition metal (Cu(I), Co(II), Mn(II), Ni(II) and Ru(II)) ions. The catalytic activity of cobalt-NNN pincer complexes have been investigated for N-alkylation of both aromatic and aliphatic amines with alcohols via BH as well as ADC of alcohols and amines to imine. We have also developed molecularly defined NNN-type cobalt pincer complex catalyzed transfer semi-hydrogenation of unbiased alkynes to Z-selective alkenes. This unified process is highly stereo-, and chemo-selective and exhibits a broad scope as well as wide functional group tolerance. Ammonia-borane (AB), a bench-stable substrate with high gravimetric hydrogen capacity was used as a safe and practical transfer hydrogenating source. Besides, the catalytic activity of arene ruthenium(II)-NNN pincer complexes have been investigated for the reduction of nitrobenzene in presence of NaBH4 in ethanol at room temperature. Furthermore, we are under the progress of the utilization of the complexes for various oxidation reactions like Olefin epoxidation, alcohol oxidation with different supporting oxidants like O2 and H2O2, etc,

Abstract

Cobaloximes are extensively used as model compounds of vitamin B12. The synthesis of cobaloximes with new synthetic routes and modified structural features continues to be a major focus in the field of research since they find applications in various fields. A series of inorganic cobaloxime complexes with pyridine and aniline based ligands substituted with carboxylic acid group have been synthesized and characterized. The crystal structures of the complexes show that the cis influence exerted by both chloride and bromide ions are approximately same. The complexes have been synthesized with various dioximes. In both dimethyl glyoxime and diphenyl glyoxime complexes, the Co-Nax distance is slightly higher in aniline substituted complex compared to the pyridine analogue. The catalytic activity of the complexes towards proton reduction in various solvents and acids have been studied. The complexes have been attached to the electrode surface and characterized. The catalytic activity of the modified electrode has been studied. The studies show that the catalyst is stable on the electrode surface. In additions, the complexes show potential application as antibacterial agents. The cobaloxime complexes were screened for their antibacterial activity against Methicilin Resistant Staphylococcus aureus (MRSA) and Acinetobacter baumannii by well diffusion method and found to exhibit inhibition against both gram positive and gram negative bacteria. The study also evaluated the efficacy of cobaloxime which could inhibit the formation of biofilms on Congo red agar medium.

Abstract

The development of artificial receptors for the recognition of Chiral species is currently of great interest as highly selective chiral sensing is imperative for many areas, including environmental, biological, clinical, and waste management applications. Fluorescent sensors have been recognized as indispensable tools for monitoring ions and biomolecules with high sensitivity in cells and tissues and their potential for progress can be explained by the distinct advantages offered by fluorescence detection in terms of sensitivity, selectivity, response time, local observation, etc. Since the enantiomeric recognition of chiral compounds was pioneered by Cram et al. in the early 1970s, investigations on highly sensitive and selective enantioselective recognition of chiral organic molecules have received increasing attention. Various techniques have been applied to detect these species, such as NMR, UV/vis, and fluorescence spectroscopy. Fluorescent and colorimetric sensors allow for the real time and space detection of analytes. Accordingly, fluorescence and colorimetric changes have been actively adopted for chiral recognition. Chiral fluorescence and colorimetric sensors can be used for rapid determination of the enantiometric composition of chiral compounds with high sensitivity and high-throughput screening (HTS) determination. The fluorescent chemosensors composed of an amino acid recognition unit (ionophore) together with a fluorogenic reporting unit (fluorophore) and thus the conjugate is described as fluoroionophore. In this present study, we describe the synthesis of a novel heterocycles based colorimetric Fluorescent chemosensors for the selective detection and chiral discrimination of naturally occurring amino acids by the dual mode experimentation of both fluorimetry and colorimetry using the supramolecular principles. Fluorophores like pyrene, anthracence, naphthalene and modular spacers like xylelene dibromide, 1,2-dibromo ethane will be used. The chiral recognition unit like amino alcohols, amino acids or other small heterocycle based chiral molecules will be inducted as the recognition unit in the fluoroionophore.

Abstract

Metal-organic frameworks (MOFs) receive great attention, due to their high porosity which promises applications in gas storage, separations, catalysis and heat transformation etc. Metal-organic framework materials (MOFs) combine the bulk phase properties of the MOFs together with the additional physical/chemical properties derived from nano-sized particles, which can display improved properties. The MOFs will be synthesized by facile hydrothermal process and ultra sonication method. The synthesized MOFs were characterized by various techniques in order to examine the structural, morphological and adsorption-desorption properties. Some of the techniques employed will be TEM, SEM, PXRD, XPS, BET and FT-IR spectroscopy. The electrochemical, photochemical properties of the MOF are determined for supercapacitor applications, phenol degradation applications. The carcinogenic cationic, anionic dyes and Phenol in contaminated water can be degraded using Novel MOFs. The degradation pathway of the pollutant molecule will be studied by LC-MS spectroscopy. The mineralization efficiency of the pollutants will be evaluated using TOC analysis. The recyclability and stability of the MOFs will be investigated by recycling the catalyst and PXRD spectroscopy.

Abstract

Among the model complexes of vitamin B12, it has been observed that the Cobaloximes RCo (L)2B simulate the reaction of vitamin B12 more closely, both qualitatively and quantitatively where R=Organo group, L=dimethyl gloxime and B= base. Since small structural changes in the molecule have a profound effect on the Co-C bond reactivity, the synthesis of new or modified Cobaloximes continues to attract the attention. A series of inorganic Cobaloximes containing aniline and substituted anilines as a neutral base have been synthesized. The complexes have been synthesized by two methods. The compounds have been characterized by IR spectroscopy. The results show that electron donating substituents weakens the Co-N bond. Co-N (base) bond is stronger in pyridine compared to aniline complexes. However more examples and characterization techniques should be taken for bringing a general conclusion.

Abstract

Ampoules are inevitable in the scientific and medical field. In the fast-moving world, simple grinding or breaking up of ampoules to utilize the medicines in it, is unsafe to humans and environment. A very small glass micro or even nano particle from ampoule may create momentum crucial death of patient. These micro glass particles are difficult to remove from the body after it has been injected along with medicine into the body such as human, animals, birds etc. Besides, there is every chance of losing the lifesaving medicines during the breaking of these ampoules. Herein, we report a new ampoule glass penetrator which does not produce any micro glass particles and cause of any injury to our body and also zero wastage of medicines during the process of work. Moreover, this glass apparatus abide the rule of green technology, because upon breaking of ampoules no glass pieces will come out of ampoules. Even after the usage of these ampoules it can be reused in a simple way of fusing it for any purpose except medical purpose. In addition, in our ampoule bottle penetrator, a temperature regulator is fixed to produce different temperature on the tungsten tip. This ensures to create a hole on different types of bottles like soda, borosilicate, lead or plastics ampoule bottles at the same time when ampoules bottles are approaching at emergency period in hospitals or Pharmaceutical industries. An indicator led light is also used to ensure the current in the AB penetrator.
