Palladium Membrane with High Density of Large-Angle Grain Boundaries to Promote Hydrogen Diffusivity
Membranes, 2022 A higher density of large-angle grain boundaries in palladium membranes promotes hydrogen diffusion whereas small-angle grain boundaries suppress it. In this paper, the microstructure formation in 10 µm thick palladium membranes is tuned to achieve a ...

Effect of pressure on the crystal structure of L-serine-I and the crystal structure of L-serine-II at 5.4 GPa [PDF]
, 2005 The crystal structure of L-serine has been determined at room temperature at pressures between 0.3 and 4.8 GPa. The structure of this phase ( hereafter termed L-serine-I), which consists of the molecules in their zwitterionic tautomer, is orthorhombic ...
