Accounts of Chemical Research, 2018 Work on the electronic structures of metal-oxo complexes began in Copenhagen over 50 years ago. This work led to the prediction that tetragonal multiply bonded transition metal-oxos would not be stable beyond the iron-ruthenium-osmium oxo wall in the periodic table and that triply bonded metal-oxos could not be protonated, even in the strongest ...

Placental MRI Predicts Fetal Oxygenation and Growth Rates in Sheep and Human Pregnancy
Advanced Science, 2022 Magnetic resonance imaging (MRI) assessment of fetal blood oxygen saturation (SO2) can transform the clinical management of high‐risk pregnancies affected by fetal growth restriction (FGR). Here, a novel MRI method assesses the feasibility of identifying

Oxygen and Cation Ordered Perovskite, Ba2Y2Mn4O11 [PDF]
, 2004 A three-step route has been developed for the synthesis of a new oxygen-ordered double perovskite, BaYMn2O5.5 or Ba2Y2Mn4O11. (i) The A-site cation ordered perovskite, BaYMn2O5+d, is first synthesized at d ~ 0 by an oxygen-getter-controlled low-O2-pressure encapsulation technique utilizing FeO as the getter for excess oxygen.

Deciphering mechanisms of enhanced-retarded oxygen diffusion in doped Si [PDF]
Appl. Phys. Lett. 103, 251909 (2013), 2013 In this letter, we study enhanced-retarded diffusion of oxygen in doped silicon by means of first principle calculations. We found that the migration of oxygen dimers can not be significantly affected by strain, doping type or rate. We attribute the enhanced oxygen diffusion in p-doped silicon to reduced monomer migration energy, and the retarded ...

Postdiagenetic Changes in Kerogen Properties and Type by Bacterial Oxidation and Dehydrogenation
Molecules, 2022 A significant part of organic carbon found on the earth is deposited as fossil organic matter in the lithosphere. The most important reservoir of carbon is shale rocks enriched with organic matter in the form of kerogen created during diagenesis.

Oxygen and nitrogen abundances in nearby galaxies. Correlations between oxygen abundance and macroscopic properties [PDF]
Astron.Astrophys. 425 (2004) 849-869, 2004 We performed a compilation of more than 1000 published spectra of HII regions in spiral galaxies. The oxygen and nitrogen abundances in each HII region were recomputed in a homogeneous way, using the P-method. The radial distributions of oxygen and nitrogen abundances were derived.

Selective control of oxygen sublattice stability by epitaxial strain in Ruddlesden-Popper films [PDF]
APL Mater. 3, 126102 (2015), 2015 Oxygen-defect control has long been considered an influential tuning knob for producing various property responses in complex oxide films. In addition to physical property changes, modification to the lattice structure, specifically lattice expansion, with increasing oxygen vacancy concentrations has been reported often and has become the convention ...
