In today’s world, no one can stand without plastic. These ingredients are enormously dependent on several industries including aerospace, food packaging, automotive, plastic shopping bags, and many more. Landfills are full of plastic waste and the accumulation of plastic waste in the environment caused many problems. Plastic shopping bags are made from polyethylene, which causes... Read More

Authors : Vincent Aroulmoji,Mohamed Mathlouthi,M.O. Portmann-Richardson,

https://doi.org/10.29294/IJASE.8.2.2021.2136-2146

The role of water in sweet taste chemoreception of small carbohydrates and artificial sweeteners was derived from physico-chemical methods and spectroscopic studies of their aqueous solutions. Likewise, surface tension, contact angles with a hydrophobic surface, and the adhesion forces to this type of surface of the aqueous solutions of sapid molecules were found to discriminate between their...

DFT Investigation of Corrosion Inhibition and Nonlinear Optical Behaviour of Phenylimidazolidin-4-One Derivative
Authors : R. Namitha,E. Vidya,

https://doi.org/10.29294/IJASE.8.2.2021.2153-2160

By using Density Functional Theory (DFT/B3LYP) some quantum chemical parameters of the previously synthesized molecule were calculated to determine the relationship between molecular structure and their inhibition efficiencies as corrosion inhibitors. The results of the quantum chemical calculations their inhibition effect are closely related to EHOMO, ELUMO, hardness, polarizability, dipole... Read More

Approach to Increase Integration Rate of Elements of a  Conventional Static Comparator
Authors : E.L. Pankratov,

https://doi.org/10.29294/IJASE.8.2.2021.2161-2180

In this paper, we introduce an approach to increase the integration rate of elements of a conventional static comparator. Framework, the approach we consider a heterostructure with special configuration. Several specific areas of the heterostructure should be doped by diffusion or ion implantation. Annealing of dopant and/or radiation defects should be... Read More

Overall Stability Analysis of Ribb Earthen Dam in Ethiopia
Authors : H. F. Gebregziabher,F. Gebrehiwot,

https://doi.org/10.29294/IJASE.8.2.2021.2181-2187

This study aimed at assessing the static and dynamic slope stability of Ribb Zoned Earthen Dam that is located in the earthquake prone areas of Ethiopia by employing finite element method using the shear strength reduction (SSR) technique of PLAXIS. The slope stability analyses were coupled with seepage analyses by considering different critical loading conditions. The peak ground acceleration... Read More

Stokes and Antistokes Raman Scattering in Heteronuclear  and Homonuclear Molecules
Authors : Rohit Singh,Amrita ,

https://doi.org/10.29294/IJASE.8.2.2021.2194-2199

Raman scattering is a consequence of quantized vibrations or rotations of molecules irradiated with monochromatic light. Some light is scattered at the same frequency (Rayleigh) and some light is scattered at different frequencies (Raman). The difference in frequency corresponds to the energy of vibrational transition. The Raman scattering can be divided into two parts, the Stokes line and the... Read More

On Prognosis of Growth of Epitaxial Layers during  Pulsed Laser Deposition under the Influence of  Changes of Parameters
Authors : E.L. Pankratov,

https://doi.org/10.29294/IJASE.8.2.2021.2219-2223

Pulsed laser deposition is one of the most promising modern approaches for producing epitaxial layers. The approach gives a possibility to apply materials with special properties (metals, carbides, etc.) to the surface of parts, which allows restoring geometry, increasing surface strength and corrosion resistance, etc. This paper considers an analytical approach for solution of partial...
