Abstract:
Some materials take place in class of smart materials with adaptive properties and stimulus response to the external changes. Shape memory alloys take place in this group with shape reversibility character and capacity of responding to changes in the environment. These alloys exhibit a peculiar property called shape memory effect, which is characterized by the recoverability of two certain shapes of material at different temperatures. This property is characterized by the recoverability of two certain shapes of material at different temperatures. These alloys possess two unique abilities: the capacity to recover large strains and to generate internal forces during their activation. Shape memory effect is initiated by successive cooling and deformation treatments, and activated thermally on heating and cooling, with which shape of material cycles between original and deformed shapes in reversible way. Therefore, this behavior can be called Thermoelasticity. The basis of this phenomenon is the stimulus-induced phase transformations, thermal and stress induced martensitic transformations, which govern the remarkable changes in internal crystalline structure and properties of the materials. Thermal induced martensitic transformation occurs on cooling, with cooperative movement of atoms in, <110> type directions on the {110} type planes of austenite matrix, along with lattice twinning and ordered parent phase structures turn into twinned martensite structures. The twinned structures turn into detwinned structures by means of stress induced transformation by stressing the material in the martensitic condition. Martensitic transformations are diffusion less transformations, and movements of atoms are confined into neighbor atom distances.

Keynote: Effect of COVID-19 pandemic on agricultural production and sustainable food system in Fiji
Time : 11:00-11:30
Biography:
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.

Neelam Hazoor Zaidi
The University of Fiji, Fiji
Keynote: Quantitative analysis of micelle-catalyzed reaction between [Cu(II)-gly-leu]+ 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.

Mohammadreza Akbari has completed Ph.D. in Civil Engineering (Structural), and Chemical Engineering (Refining), Tehran University, Tehran, Iran. Specialized in innovator a method for Analytical Solving Nonlinear Differential Equations (Coupled Nonlinear Differential Equations, PDE , ODE) in the all Engineering fields which is entitled ‘’AGM ‘’ so it is abbreviation Akbari-Ganji Method.
Abstract:
In this paper, our aims are accuracy, capabilities and power at solving of the complex non-linear differential at the reaction chemical in the catalyst reactor (heterogeneous reaction ). Our purpose is to enhance the ability of solving the mentioned nonlinear differential equations at chemical engineering and similar issues with a simple and innovative approach which entitled ‘’Akbari-Ganji's Method’’ or ‘’AGM’’. In this article,we proved that with this new method, all kinds of complex practical problems related to nonlinear differential equations can be easily solved analytically for chemical reactors design.Obviously,most of the phenomena in dynamics and aerodynamics are nonlinear, so it is quite difficult to study and analyze nonlinear mathematical equations in this area,also we wanted to demonstrate the strength, capability and flexibility of the new AYM method(Akbari-Yasna Method).This method is newly created and it can have high power in analytical solution of all kinds of industrial and practical problems in engineering fields and basic sciences for complex nonlinear differential equations

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.
