Understanding Water Activity in Deep Eutectic Solvents: Experimental Screening, Thermodynamic Modeling, and QSAR Predictions

ChemistrySelect, Volume 11, Issue 21, 4 June 2026.
Water activity (aw) was measured in eight DESs (10–90 wt% water). Strong DES–water interactions persist to ∼50 wt%, after which structure collapses toward aqueous‐like behavior. Redlich–Kister, Wilson, and COSMO‐RS models showed limited performance, whereas QSAR modeling using COSMOtherm‐derived σ‐profile descriptors significantly improved aw ...

Assessing Water Solubility of Ester‐Based Oils and Unravelling Their Mechanisms by a Quantitative Model

High Voltage, Volume 11, Issue 3, Page 797-810, June 2026.
ABSTRACT Moisture is a sensitive issue for transformer oils, as it adversely affects the stability of insulation papers and dielectric strength of the oils. However, the lack of a quantitative model makes it challenging to evaluate the water solubility of ester‐based oils, which is an undesirable restriction for developing novel ester‐based oils ...

Screen ammonium‐based deep eutectic solvents for CO2 capture: Extended UNIFAC‐DES, calibrated COSMO‐RS, and experiment

AIChE Journal, Volume 72, Issue 2, February 2026.
Abstract CO2 solubility in deep eutectic solvent (DES) is a critical property to indicate the competence of using DESs for carbon capture. This work presents a systematic screening framework with computational and experimental procedures to identify the promising ammonium‐based DESs for CO2 absorption.

Predicting Liquid Organic Hydrogen Carrier Saturation in Dehydrogenation Cell Gas Diffusion Layers for Hydrogen Storage

ChemCatChem, Volume 17, Issue 16, August 18, 2025.
The influence of gas diffusion layer (GDL) microstructures on mass transport and methylcyclohexane saturation (MCH) in a dehydrogenation cell was investigated using pore network modeling. We reveal that GDLs with larger pore diameters (dpore) and lower tortuosity (τ) enable enhanced MCH invasion, thereby improving reactant concentration at the catalyst.

Prediction of vapor-moisture equilibriums for a wood-moisture system using a modified UNIQUAC model

, 2006
A modified UNIQUAC model has been extended to describe and predict the equilibrium relative humidity and moisture content for wood. The method is validated over a range of moisture content from oven-dried state to fiber saturation point, and over a ...
