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 ...

Sustainable and cost‐effective process design for energy‐self‐sufficient ethyl lactate production from sugar mill feedstocks: a techno‐economic approach

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 487-507, March/April 2026.
Abstract Bio‐based ethyl lactate (EL) can replace several fossil‐derived products owing to its low toxicity, high solvent functionality, and environmental advantages. This study assesses the techno‐economic viability and greenhouse gas (GHG) reduction potential of producing EL from sugarcane A‐molasses and lignocelluloses in an energy self‐sufficient ...

Ternary liquid–liquid equilibria for 2-phenylethyl acetate + 2-phenylethanol + water and 2-phenylethyl acetate + acetic acid + water at atmospheric pressure

Results in Chemistry, 2023
2-Phenylethyl acetate can normally be produced by the esterification of 2-phenylethanol with acetic acid via a reactive distillation process. The multiphase coexistence behavior is a component of esterification and is important for the design of the ...

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.

Experimental determination and prediction of solid-liquid phase equilibria for binary (N-(2-acetoxyethyl)-p-nitroaniline (1) + N-ethyle-4-nitroaniline (2)) mixture

MATEC Web of Conferences, 2013
The nitrocellulose based materials are degraded in a natural way during their storage; the processes of degradation are accelerated when the temperature or the humidity increases.
