Mapping the Catalytic Cycle of Ru‐Catalyzed Ammonia Oxidation
Angewandte Chemie, EarlyView.The graph illustrates the complete electrochemical ammonia oxidation catalytic cycle by a ruthenium complex, capturing most intermediates. The pathways bifurcate at [RuIII(NH2)]2+ and [RuII(N2H4)]2+, highlighting competitive steps including dimerization, nucleophilic attack, and disproportionation.

Photodestruction of Diatomic Molecular Ions: Laboratory and Astrophysical Application
Molecules, 2020 In this work, the processes of photodissociation of some diatomic molecular ions are investigated. The partial photodissociation cross-sections for the individual rovibrational states of the diatomic molecular ions, which involves alkali metals, as well ...

The effects of nitric oxide cooling and the photodissociation of molecular oxygen on the thermosphere/ionosphere system over the Argentine Islands [PDF]
Annales Geophysicae, 1997 In the past the global, fully coupled, time-dependent mathematical model of the Earth's thermosphere/ionosphere/plasmasphere (CTIP) has been unable to reproduce accurately observed values of the maximum plasma frequency, foF2, at extreme geophysical ...

Photogeneration and Visualization of a Surface‐Stabilized Dinitrene
Angewandte Chemie, EarlyView.In this communication we report the formation of a stable, surface‐supported dinitrene achieved through the photolysis of a diazide precursor on an Au(111) metal substrate. We combine high‐resolution scanning probe techniques with theoretical calculations, providing the first real‐space imaging of a metal nitrene adsorbed on a surface and exploring the

Experimental Study of the Laser-Induced Oxyhemoglobin Photodissociation in Cutaneous Blood Vessels
Acta Medica Bulgarica, 2015 A new optical method for reduction of local tissue hypoxia is proposed. It is shown that this method of phototherapy allows the control of a local oxygen concentration in tissue.

Determination of photodissociation and radiative association cross sections from the same time-dependent calculation [PDF]
, 2013 We illustrate some of the difficulties that may be encountered when computing photodissociation and radiative association cross sections from the same time-dependent approach based on wavepacket propagation. The total and partial photodissociation cross sections from the thirty-three vibrational levels of the b triplet {\Sigma}+ state of HeH+ towards ...

Model for Atomic Oxygen Visible Line Emissions in Comet C/1995 O1 Hale-Bopp
, 2012 We have recently developed a coupled chemistry-emission model for the green and red-doublet emissions of atomic oxygen on comet Hyakutake. In the present work we applied our model to comet Hale-Bopp, which had an order of magnitude higher H2O production ...
