Modelling Primordial Gas in Numerical Cosmology [PDF]

, 1996
We have reviewed the chemistry and cooling behaviour of low-density (n H2 + H+, and H- + H -> H2 + e-, is likely to be converted into its para configuration on a faster time scale than the formation time scale.

On-surface light-induced generation of higher acenes and elucidation of their open-shell character

Nature Communications, 2019
The synthesis of large acenes via traditional solution-chemistry routes is hindered by their poor solubility and high reactivity under ambient conditions.

Effects of vibrational excitation on the F + H2O → HF + OH reaction: dissociative photodetachment of overtone-excited [F-H-OH]. [PDF]

, 2017
The reaction F + H2O → HF + OH is a four-atom system that provides an important benchmark for reaction dynamics. Hydrogen atom transfer at the transition state for this reaction is expected to exhibit a strong dependence on reactant vibrational ...

AQUA AMMONIA ELECTROLYTIC CHARACTER AND TPP COOLANT CONDUCTOMETRIC QUALITY CONTROL UNDER HIGH TEMPERATURES AND PRESSURES

Advanced Engineering Research, 2013
To improve the operational conductometric steam quality control at the TPP, CHPP, and NPP, the technique for NaCl and NH4OH concentration in the saturated and superheated steam of the high- and supercritical pressure steam generators is developed, and a ...

Redox driven B12-ligand switch drives CarH photoresponse

Nature Communications, 2023
CarH is a coenzyme B12-dependent photoreceptor involved in regulating carotenoid biosynthesis. How light-triggered cleavage of the B12 Co-C bond culminates in CarH tetramer dissociation to initiate transcription remains unclear. Here, a series of crystal

Controlling Chemical Reactions in Confined Environments: Water Dissociation in MOF-74

Applied Sciences, 2018
The confined porous environment of metal organic frameworks (MOFs) is an attractive system for studying reaction mechanisms. Compared to flat oxide surfaces, MOFs have the key advantage that they exhibit a well-defined structure and present significantly

Formation of ultracold RbCs molecules by photoassociation

, 2011
The formation of ultracold metastable RbCs molecules is observed in a double species magneto-optical trap through photoassociation below the ^85Rb(5S_1/2)+^133Cs(6P_3/2) dissociation limit followed by spontaneous emission.

Broken-Symmetry Unrestricted Hybrid Density Functional Calculations on Nickel Dimer and Nickel Hydride [PDF]

, 2004
In the present work we investigate the adequacy of broken-symmetry unrestricted density functional theory (DFT) for constructing the potential energy curve of nickel dimer and nickel hydride, as a model for larger bare and hydrogenated nickel cluster ...

From planes to bowls: photodissociation of the bisanthenequinone cation

, 2018
We present a combined experimental and theoretical study of the photodissociation of the bisanthenequinone (C28H12O2) cation, Bq+. The experiments show that, upon photolysis, the Bq+ cation does not dehydrogenate, but instead fragments through the ...
