Autor: Xuban Gastearena, Jesus M. Ugalde, German E. Pieslinger, Eider San Sebastian, Elisa Jimenez-Izal
Publikováno v: Communications Physics, Vol 7, Iss 1, Pp 1-6 (2024)
Abstract Recently, a three dimensional metal-organic framework (MOF) based on Dy(III) and the L-tartrate ligand was experimentally shown to exhibit a spin polarization (SP) power of 100% at room temperature. The material’s spin filtering ability wa

Publikováno v: Physical Chemistry Chemical Physics. 24:5323-5329
The mechanism for the photocatalytic activation of Pt(IV) anticancer prodrugs by riboflavin in the presence of NADH has been investigated by DFT. In the first step of the reaction, the oxidation kinetics of NADH to afford the catalytically active rib
