Modeling Dissociation-Vibration Coupling with the Macroscopic Chemistry Method [PDF]

open access: yesAIP Conference Proceedings, 2005
We test the recently developed macroscopic approach to modeling chemistry in DSMC [Lilliley & Macrossan, Physics of Fluids, 16(6), 2054-2066 (2004)], by simulating the flow of rarefied dissociating nitrogen over a blunt cylinder. In this macroscopic method, chemical reactions are decoupled from the collision routine.

Gas phase bond dissociation enthalpies and enthalpies of isomerization/reaction for small hydrocarbon combustion related compounds between 300 and 1500 K: A comparison of Gaussian-4 (G4) theoretical values against experimental data [PDF]

open access: yes, 2010
Gas phase calculations at 1 atmosphere pressure between 300 and 1500 K at 200 K intervals were conducted using the Gaussian-4 (G4) composite method level of theory on a representative set of reactions having broad relevance in hydrocarbon combustion ...

Electrolytic properties of carbonic acid solutions and innovative methods of operational control of water quality such as condensation at TPP

open access: yesAdvanced Engineering Research, 2015
The work objective is to improve the operational conductometric vapor quality control at the thermal power plants. To this end, methods identifying СО2 concentrations in the vapor under the neutral aqueous-chemical mode without ammonia addition are ...

Model for acid-base chemistry in nanoparticle growth (MABNAG) [PDF]

open access: yesAtmospheric Chemistry and Physics, 2013
Climatic effects of newly-formed atmospheric secondary aerosol particles are to a large extent determined by their condensational growth rates. However, all the vapours condensing on atmospheric nanoparticles and growing them to climatically relevant ...

CheMPS2: a free open-source spin-adapted implementation of the density matrix renormalization group for ab initio quantum chemistry [PDF]

open access: yes, 2014
The density matrix renormalization group (DMRG) has become an indispensable numerical tool to find exact eigenstates of finite-size quantum systems with strong correlation.

Optimizing Optical Absorption, Exciton Dissociation, and Charge Transfer of a Polymeric Carbon Nitride with Ultrahigh Solar Hydrogen Production Activity.

open access: yesAngewandte Chemie, 2017
Polymeric or organic semiconductors are promising candidates for photocatalysis but mostly only show moderate activity owing to strongly bound excitons and insufficient optical absorption.
