DOI: 10.1039/d2cc05606b
Abstract: The closed-shell nature of Xe atoms precludes the formation of Xe-Xe bonds other than based on van der Waals interactions. Here, we present experimental evidence showing that the complexation of Xe atoms to a Au+… read more here.

DOI: 10.1111/1556-4029.15039
Abstract: Friction ridge analysis would not have been one of the most recognized branches of forensics without molecular spectroscopy. The phenomenon of fluorescence is used on daily basis to develop latent fingerprints and to enhance those… read more here.
