Arne Magnéli, 1914–1996

Redox pioneer: Professor Arne Holmgren.

Dr. Arne Holmgren (Ph.D., 1968) is recognized here as a redox pioneer, because he has published at least one article on redox biology that has been cited over 1000 times and has published at least 10 articles, each cited over 100 times. He is widely known for his seminal discoveries and in-depth studies of thioredoxins, thioredoxin reductases, and glutaredoxins. Dr. Holmgren, active throughout ...

The vanadium Magnéli phases V

To compare the metal-insulator transitions (MITs) of VO2 and V2O3 we analyze the relations between the structural and electronic properties of the vanadium Magnéli phases. These materials set up the homologous series VnO2n−1 (3 ≤ n ≤ 9) and have crystal structures comprising typical dioxide-like and sesquioxidelike regions. As the MITs of the vanadium Magnéli phases are accompanied by structura...

TheMetal - Insulator Transition of the Magnéli phase

– The metal-insulator transition (MIT) of the Magnéli phase V4O7 is studied by means of electronic structure calculations using the augmented spherical wave method. The calculations are based on density functional theory and the local density approximation. Changes of the electronic structure at the MIT are discussed in relation to the structural transformations occuring simultaneously. The ana...

Coulomb-potential-dependent decohesion of Magnéli phases.

Transition metal oxide Magnéli phases are traditionally described as crystallographic shear structures. Some of these phases feature a layered crystal structure based on deformed metal-oxygen octahedra. Here, we describe the correlation between structure, decohesion energies and elastic properties of WO(3), ReO(3), MoO(2), VO(2), V(2)O(5) and TiO(2) using ab initio calculations. Decohesion ener...
