Toward broadband mechanical spectroscopy. [PDF]
Proc Natl Acad Sci U S A, 2017 Significance Viscous liquids of all kinds, from honey to glycerol to common polymers, display remarkably similar dynamical properties upon cooling from high temperatures at which local structural relaxation and flow occur quickly, to moderate temperatures at which key components of the dynamics slow down dramatically, to cold temperatures at ...

Damping of Fe-Al Alloy Electrodeposited in an Ionic Liquid [PDF]
Materials Research, 2018 Iron-Aluminium alloys were produced by the electro-deposition of iron-aluminium on a copper substrate. The electro-deposition process was done in the ionic liquid 1-butyl-1-methylpyrrolidinium trifluoromethylsulfonate, [Py1,4]TfO.
