Challenges, models, and algorithms for flow and transport simulations in deep reservoirs

open access: yesDeep Underground Science and Engineering, EarlyView.
Deep reservoirs are considered a promising resource for future energy supply, but current reservoir simulation technologies may face certain challenges if they are directly used in specific scenarios in deep reservoir development. Models and algorithms were developed to resolve these challenges, including a better phase equilibrium model, a better ...

Ab initio intermolecular interactions mediate thermochemically real-fluid effects that affect system reactivity [PDF]

open access: yesarXiv
The properties of supercritical fluids are dictated by intermolecular interactions that involve two or more molecules. Such intermolecular interactions were described via intermolecular potentials in historical supercritical combustion modeling studies, but have been treated empirically and with no consideration of radical interactions or multi-body ...

2‐Formyl‐5‐(hydroxymethyl)furan (HMF) Derivatives as Active Complexing Agent for CO2 Insertion Reaction

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Renewable‐based furanics derived from 5‐HMF are used to synthesize cyclic organic carbonates (COCs) via CO2 insertion into epoxides. The BHTHF/NaBr complexing system shows high activity, achieving 94–99% epoxide conversion and 70–99% COC selectivity under mild conditions.

Transition‐Metal‐Free Carboxylation of Aryl Boronates in Supercritical CO2

open access: yesEuropean Journal of Organic Chemistry, Accepted Article.
Carboxylation using stable and abundant CO2 as a carbon source would be an attractive option in synthetic organic chemistry if the use of highly reactive organometals or toxic and expensive transition metals can be avoided. Herein we report a transition‐metal‐free direct carboxylation of aryl trialkoxyboronates in supercritical CO2 (scCO2), promoted by

Insights Into the Enantioseparation of Polyhalogenated 4,4′‐Bipyridines With a Cellulose Tris(3,5‐Dimethylphenylcarbamate)‐Based Chiral Column by Using Supercritical Fluid Chromatography

open access: yesELECTROPHORESIS, EarlyView.
ABSTRACT In the last decade, by integrating experimental and computational analyses, it was demonstrated that halogen bond (HaB) may contribute to binding and enantiorecognition mechanisms underlying the HPLC enantioseparation of halogenated chiral analytes by using cellulose tris(3,5‐dimethylphenylcarbamate) (CDMPC)‐based chiral columns and n‐hexane ...
