Abstract: Abstract A first-principles calculation reveals that the phase that is precipitated in a grain boundary weakens the cohesiveness of the grain boundary. The hydrogen atom is likely to be trapped in the Al/MgZn2 boundary when… read more here.

Abstract: Introduction: Primitive chondrititc meteorites contain mmto cm-sized assemblages of Caand Albearing oxides and silicates. So-called calcium-aluminum-rich inclusions (CAIs) have radiometric age dates of 4.5673 Ga, exceeding those of all other solar-system materials [1]. Moreover, equilibrium… read more here.
