Published in 2018 at "ACS Applied Energy Materials"

DOI: 10.1021/acsaem.8b01345

Abstract: Photocatalysis represents a unique class of chemical transformations. It utilizes the energy delivered by light and drives reactions that are difficult, sometimes even impossible, to carry out in dark. When used for thermodynamically uphill reactions… read more here.

Published in 2020 at "Powder Metallurgy"

DOI: 10.1080/00325899.2020.1834748

Abstract: ABSTRACT The mechanisms of densification during spark plasma sintering (SPS) of spherical copper particles are investigated both experimentally and analytically. Experimentally measured densification rates are compared to expected contributions to densification coming from Coble creep,… read more here.
