Plasmonic Cu2−xS Nanocrystals: Optical and Structural Properties of Copper-Deficient Copper(I) Sulfides
TL;DR: It is found consistently that under ambient conditions the copper deficient Cu(1.97)S (djurleite) is more stable than Cu(2) S (chalcocite) and this may be the reason behind the traditionally known instability of the bulk Cu( 2)S/CdS interface.

Sonochemical synthesis of amorphous iron
TL;DR: In this paper, the synthesis of metallic glass powders using the microscopically extreme (yet macroscopically mild) conditions induced by high-intensity ultrasound was described, and the results showed that metallic glass powder is a highly active catalyst for the Fischer-Tropsch hydrogenation of carbon monoxide and for hydrogenolysis and dehydrogenation of saturated hydrocarbons.
