A COMBINED FIRST PRINCIPLES AND MOHR-COULOMB CRITERION FOR THE DETERMINATION OF THE NANOHARDNESS OF AMORPHOUS SILICON

A combined first principles and Mohr-Coulomb criterion for the determination of the nanohardness of amorphous silicon

Although, the evaluation of the nanohardness Sea Food of amorphous silicon (a-Si) has been the subject of a few experimental works but, to date, it has not been addressed theoretically yet.In this work, first principles Kohn-Sham density functional theory (DFT)-based molecular dynamics (MD) in combination with Mohr-Coulomb criterion is employed to

Biocompatible wear-resistant thick ceramic coating

Sensitisation to immunologically active elements like chromium, cobalt or nickel and debris particle due to wear are ORG COFFEE SUBSTITUTE serious problems for patients with metallic implants.We tested the approach of using a hard and thick ceramic coating as a wear-resistant protection of titanium implants, avoiding those sensitisation and Eggs fo
