INVESTIGATION OF THE DISSOCIATION CHEMISTRY OF -NF2 COMPOUNDS

open access: yes, 1962
: Thermal dissociation experiments using adiabatic compression as the means of heating were discontinued. A study of the adiabatic compression process in the TEI apparatus showed that because of the mechanical properties of the compressor and the high ...

Computational chemistry considerations in catalysis: Regioselectivity and metal-ligand dissociation

open access: bronzeCatalysis Today, 2020
Abstract The utility of a range of computational chemistry approaches for the prediction of the regioselectivity for hydroformylation processes and metal-ligand dissociation in a model organometallic system is considered to provide insight about computational strategies for use in catalysis.

Impact of High Methane Flux on the Properties of Pore Fluid and Methane-Derived Authigenic Carbonate in the ARAON Mounds, Chukchi Sea

open access: yesFrontiers in Marine Science, 2022
We investigated the pore fluid and methane-derived authigenic carbonate (MDAC) chemistry from the ARAON Mounds in the Chukchi Sea to reveal how methane (CH4) seepage impacts their compositional and isotopic properties.

Migration of Salt Ions in Frozen Hydrate-Saturated Sediments: Temperature and Chemistry Constraints

open access: yesGeosciences, 2022
Migration of dissolved salts from natural (cryopeg brines, seawater, etc.), or artificial sources can destabilize intrapermafrost gas hydrates. Salt transport patterns vary as a function of gas pressure, temperature, salinity, etc. The sensitivity of the

Probing electron localization during molecular dissociation by femtosecond strong-field ion momentum spectroscopy

open access: yesCommunications Physics, 2023
The study of molecular valence electron dynamics and their coupling with nuclear motion is one of the frontiers of ultrafast physics and ultrafast chemistry. With time-resolved strong-field ion momentum spectroscopy, we study electron valence and nucleus

The terminator "toy" chemistry test: a simple tool to assess errors in transport schemes [PDF]

open access: yesGeoscientific Model Development, 2015
This test extends the evaluation of transport schemes from prescribed advection of inert scalars to reactive species. The test consists of transporting two interacting chemical species in the Nair and Lauritzen 2-D idealized flow field. The sources
