Nanomoulding with amorphous metals
Nature, 2009Nanoimprinting promises low-cost fabrication of micro- and nano-devices by embossing features from a hard mould onto thermoplastic materials, typically polymers with low glass transition temperature. The success and proliferation of such methods critically rely on the manufacturing of robust and durable master moulds.

Physical Review Letters, 2005
We report cerium-based bulk metallic glasses with an exceptionally low glass transition temperature Tg, similar to or lower than that of many polymers. We demonstrate that, in near-boiling water, these materials can be repeatedly shaped, and can thus be regarded as metallic plastics.

Thermoplastic forming of amorphous metals
Journal of Physics: Condensed Matter, 2020Abstract Amorphous metals display an extraordinary mechanical strength and elasticity and can at the same time be formed like thermoplastic polymers. These properties make them the ideal material for industrial applications where complex parts have to withstand high mechanical loads.

Amorphous Metal–Organic Frameworks
Accounts of Chemical Research, 2014Crystalline metal-organic frameworks (MOFs) are porous frameworks comprising an infinite array of metal nodes connected by organic linkers. The number of novel MOF structures reported per year is now in excess of 6000, despite significant increases in the complexity of both component units and molecular networks.

Relaxation of Amorphous Metallic Alloys
Solid State Phenomena, 1998Two types of relaxation processes in amorphous alloys have been investigated in metal-metalloid systems. One of them has been studied by measuring the static structure factor S(Q) in cobalt boron glass samples that have been previously isothermally treated on temperatures close to crystallization temperature.

Hydrogen in amorphous metals—I
Acta Metallurgica, 1982The solubility and diffusivity of hydrogen in amorphous Pd77.5Cu6Si16.5 and Ni49.9Pd31.8P18.3 have been measured using an electrochemical method. The pressure-concentration isotherms show remarkable deviations from Sievert's Law while the amount of hydrogen dissolved lies in between the solubility of the components of the alloy.

Hydrogen in amorphous and nanocrystalline metals
Materials Science and Engineering, 1988Abstract Experimental results on hydrogen solubility, diffusivity and phase changes are presented for nanocrystalline palladium and compared with those for amorphous PdSi and amorphous NiTi alloys. The solubility of the amorphous alloys can be explained by assuming a gaussian distribution for the site energies.
