Microhardness of II-VI and III-V Semiconductors
Abstract: A correlation between microhardness and bond hardness of II-VI and III-V semiconductors is presented in this study. Bond hardness is calculated using valence electron number, covalent / ionic radius and co-ordination number of bonded atoms of the tetrahedral semiconductors. The covalent and ionic contributions to bond hardness are separately calculated to get resultant bond hardness. Results obtained using the correlation agrees well with the reported, experimental and theoretical values of …

Elucidating the Role of Temperature in Reproductivity of Plants
Abstract: Analysis on plant counter to temperature stress accumulates interest because of the expanded mindfulness with respect to an unnatural weather change. High and low temperature stresses help in setting up the slight natural division of refined plants, the restricted geographic expansion of some other financially healthfully significant species, and furthermore produce lopsided connection for certain species. All things considered, the view of plant reprisal to temperature stress falls behind other …
