The COVID-19 pandemic and the restrictions that came with it led to unprecedented disruptions in learner development and put them at risk of poor developmental outcomes. It is thus important that the extent of the disruption on their development and

High alloyed β-phase stabilised titanium alloys are known to have low elastic moduli comparable to that of the human bone (≈30 GPa). The β-phase in titanium alloys exhibits an elastic modulus of about 60-80 GPa, which is nearly half that of α-ph

Elastic modulus is a very important physical aspect for biomaterials which is impartial to various replacements as artificially hip joints, bone plate, and gum implants since it measures the material’s resistance to be deformed elastically. This is

The stability of the Ti50Pd50-xRux alloy was investigated using first-principles density functional theory within the plane-wave pseudopotential method. Firstly, the Ti50Pd50 gave equilibrium lattice parameter and lowest heats of formation in better
