Transport and coarsening of gold nanoparticles in an orogenic deposit by dissolution–reprecipitation and Ostwald ripening

open access: yesCommunications Earth & Environment, 2021
The role of nanoparticle gold in the formation of gold deposits has long been debated. Evidence in support of this process is generally limited to epithermal-, Carlin- and seafloor massive-sulfide-type deposits where gold nanoparticles are associated ...

Sulfide mineralization, native gold and its geochemical connections in the Riphean deposits of the Avzyan ore-bearing region (the Southern Urals) [PDF]

open access: yes, 2018
In the Avzyan ore-bearing region the sulfides from the low-sulfide gold-quartz deposits (Ulyuk-Bar, Kurgashly) are characterized by higher concentrations of As, Co, Ni, Cu, Pb in comparison with sulfides from sediments outside of ore-bearing zones.

Electrophoretic deposition of WS2 flakes on nanoholes arrays. Role of the used suspension medium [PDF]

open access: yeshttps://www.mdpi.com/1996-1944/12/20/3286, 2019
Here we optimized the electrophoretic deposition process for the fabrication of WS2 plasmonic nanohole integrated structures. We showed how the conditions used for the site selective deposition influenced the properties of the deposited flakes. In particular, we investigated the effect of different suspension medium used during the deposition both in ...
