Title: quantitative analysis of micelle catalyzed reaction between complex with ninhydrin
Time : 10:30-11:00
Biography:
Dr. Neelam Hazoor Zaidi is working as a Senior Lecturer at UPSM & HS, Fiji. She has done BSc. (Hons.), MSc., and PhD in Chemistry from Aligarh Muslim University, Aligarh, UP, INDIA, and having more than 15 years of teaching and research experience in universities including 10 years at Fiji National University. In addition, she also worked for two years as Post Doctorate Research Fellow in Nanotechnology project at Indian Institute of Technology Delhi, sponsored by Council of Scientific and Industrial Research (CSIR-HRDG)–New Delhi, India. She has published numerous research papers in reputed Schimago and Scopus ranked international journals and also published book Chapters.
Abstract:
In the present paper, the kinetics of interaction of dipeptide glycyl leucine (Gly-Leu) metal complex, [Cu(II)-Gly-Leu]+ with ninhydrin has been studied by following the reaction spectrophotometrically at 70ºC and a specific pH 5.0 in the absence and presence of conventional cetyltrimethylammonium bromide (CTAB). The order of the reaction with respect to [Cu(II)-Gly-Leu]+ was unity while concerning [ninhydrin] was fractional. Furthermore, the reaction constants involved in the mechanism were obtained and experimental results have been derived on the basis of the proposed mechanism. Quantitative kinetic analysis of kψ–[CTAB] data was explained in terms of pseudo-phase of the micelles.

Abstract:
The COVID-19 pandemic has caused unforeseen adverse circumstances around the world, affecting the agricultural area, economy, human well-being, and food security. This study analyzed research on Coronavirus according to agricultural creation and food security. Pacific Island Nations (Kiribati, Fiji, Samoa, and numerous others) depend on fisheries and horticultural frameworks for their work and monetary turn of events. However, the situation with the Coronavirus has caused a significant decline in the farming stockpile, economy, and food security framework, leading to neediness, an increase in the unemployment rate, and a reduction in the trip business.

Abstract:
Renewable energy alternative promising with Organic photovoltaic cells convert sunlight into electricity. They are several polymeric materials that are light, flexible, inexpensive to manufacture and adjustable at molecular level. To this end, an investigation of charge transport by ADF/PBE0/DZ and TD-DFT quantum methods in the molecule-to-molecule hopping regime through charge transfer integrals and reorganisation energies was performed on an OLED α-NPD semiconductor in amorphous and crystalline structure, exposing its optoelectronic properties in aggregate configurations. For each α-NPD configuration with 1050 isolated monomers molecules, the transfer integrals of more than 10.000 dimers were determined and rationalised by overlapping HOMO or LUMO orbitals, for both hole and electron transport. The comparison of the average charge transfer integrals in the two structures suggests that holes move as fast in amorphous structure then in crystalline structure, which allows to propose in the performance the aggregate in amorphous structure for Organic Electronic Devices.
