Previous comparative studies on the impact of cryogenic mechanical milling (CMM) of polymers showed significantly changed thermal and mechanical properties and—in the case of some polymer blends (e.g., PMMA/PVDF) an improved miscibility. Those chan

Oxidation kinetics of bulk Zr-based metallic glasses seems to be controlled by oxygen diffusion through the scale towards the ZrO 2 /glass interface. Two modes of oxidation were observed: depending on the alloy either: (1) relative slow growth of hom

Cu–Zr-based bulk metallic glasses are of increasing interest due to their excellent properties. Cu-rich Cu 60 Zr 30 Ti 10 and Zr-rich Zr 69.5 Cu 12 Ni 11 Al 7.5 glasses (numbers indicate at.%) are examples which combine good glass forming ability w

We report on the direct determination of the hydrogen self-diffusion constant D in the hydrogen-storage Zr 69.5 Cu 12 Ni 11 Al 7.5 alloy, prepared in both the icosahedral quasicrystalline and the bulk metallic glass phases, using the technique of NMR

Nanocrystalline Mg powder without and with 2 mol% Nb 2 O 5 catalyst was studied in a 6 M KOH electrolyte as electrode material for electrochemical hydrogen charging processes. Since the hydrogen overpotential of Mg, which is a measure of the hydrogen
