Comparative study on the gas to solution phase solvation free energies of model combustion flue gas compounds (N~2~, O~2~, CO~2~, H~2~O, SO~2~, and CO) in 178 organic solvents using the IEFPCM-UFF, CPCM, and SMD implicit solvent models at the Gaussian-4 (G4) level of theory [PDF]

open access: yes, 2010
Gas to solution phase Gibbs free energies of solvation at 298.15 K for transfer of six representative combustion flue gas compounds (N~2~, O~2~, CO~2~, H~2~O, SO~2~, and CO) were calculated at the Gaussian-4 (G4) level of theory using the IEFPCM-UFF ...

Rhodium colloidal suspension deposition on porous silica particles by dry impregnation: Study of the influence of the reaction conditions on nanoparticles location and dispersion and catalytic reactivity [PDF]

open access: yes, 2009
Rhodium composite nanomaterials were synthesized by an innovating process called dry impregnation in a fluidized bed. It consists in spraying an aqueous colloidal suspension of rhodium on silica porous particles.

Energy efficiency of a hydrogen supply system using the reaction cycle of methylcyclohexane-toluene-hydrogen

open access: yesMechanical Engineering Journal, 2017
In this research, we investigated an energy supply system based on hydrogen derived from renewable energy. We modeled the energy flow and efficiency of a system using the MCH-toluene-hydrogen reaction cycle (MTHR) by methylcyclohexane (MCH, C6H11CH3) and

Study of Cyclohexane and Methylcyclohexane Functionalization Promoted by Manganese(III) Compounds

open access: yesInorganics, 2023
Alkane functionalization using safe and low-energy processes is of great interest to industry and academia. Aiming to contribute to the process of saturated hydrocarbon functionalization, we have studied a set of three manganese(III) complexes as ...

Convergent Total Synthesis of 16β‐Hydroxylpseudobufarenogin

open access: yesAngewandte Chemie, EarlyView.
We present a novel convergent strategy that integrates Pd/Ag‐promoted Suzuki–Miyaura coupling with Ir‐catalyzed radical‐relay cyclization, enabling the first total synthesis of 16β‐hydroxylpseudobufarenogin. This approach is broadly applicable to the total synthesis of various oxygenated bufadienolides by simply modifying the fragment structures ...

Methyl-Cyclohexane Methanol (MCHM) Isomer-Dependent Binding on Amorphous Carbon Surfaces

open access: yesMolecules, 2021
In January 2014, over 10,000 gallons of methyl-cyclohexane methanol (MCHM) leaked into the Elk River in West Virginia, in a chemical spill incident that contaminated a large portion of the state’s water supply and left over 300,000 residents without ...

Conformational Landscapes in the Ground and Excited States Dictate Circularly Polarized Excimer Emission: A Thermodynamic–Kinetic Interplay in Carbazole Dimer Systems

open access: yesAngewandte Chemie, EarlyView.
Covalently linked carbazole dimers exhibit intense excimer‐based circularly polarized luminescence (CPL). A simple propylene‐tethered dimer achieves glum ≈ 0.01 in the violet region—among the highest for small organic emitters without heavy atoms. Conformational mapping reveals CPL is governed by thermodynamic/kinetic control of emissive conformers ...

Ozone and alkyl nitrate formation from the Deepwater Horizon oil spill atmospheric emissions [PDF]

open access: yes, 2012
Ozone (O3), alkyl nitrates (RONO2), and other photochemical products were formed in the atmosphere downwind from the Deepwater Horizon (DWH) oil spill by photochemical reactions of evaporating hydrocarbons with NOx (=NO+NO2) emissions from spill response

Simultaneous free-volume modeling of the self-diffusion coefficient and dynamic viscosity at high pressure [PDF]

open access: yes, 2004
International audienceA free-volume model of the dynamic viscosity and the self-diffusion coefficients was discussed. The temperature-pressure variations of the dynamic viscosity and the self-diffusion coefficients of small molecules were predicted.
