Picosecond ultrasonic measurements using an optical mask.

Ultrasonics

Miao Q, Liu LW, Grimsley TJ, Nurmikko AV, Maris HJ.
PMID: 24767174
Ultrasonics. 2015 Feb;56:141-7. doi: 10.1016/j.ultras.2014.04.002. Epub 2014 Apr 13.

In this paper we describe results obtained using a variation of the picosecond ultrasonics technique. We place a transparent optical mask very close to the surface of the sample. The lower surface of the mask has a series of...

Various platinum-free electrocatalysts have been explored for hydrogen evolution reaction in acidic solutions. However, in economical water-alkali electrolysers, sluggish water dissociation kinetics (Volmer step) on platinum-free electrocatalysts results in poor hydrogen-production activities. Here we report a MoNi
