Recent Developments in Sustainable Solubilization

open access: yesChemSusChem, Volume 19, Issue 8, 28 April 2026.
We highlight several recent developments in sustainable solubilization. Particular attention is given to the use of bio‐based solvents derived from renewable resources, the strategic use of water as a solvent, and alternative, sustainable solubilizers such as hydrotropes.

A Sustainable Borrowing Hydrogen Strategy in Natural Deep Eutectic Solvents for the N‐Alkylation of Amines From Alcohols

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 16, 25 April 2026.
A sustainable, ligand‐free Pd‐catalyzed borrowing hydrogen protocol in a biodegradable hydrophobic natural deep eutectic solvent (NADES) (thymol/DL‐menthol) enables the N‐alkylation of primary amines with benzylic alcohols under mild, aerobic conditions, allowing efficient reuse of both catalyst and solvent for seven consecutive cycles. The hydrophobic

Observations of Coherence Changes in C‐Band SAR Linked to Snow Thermodynamics and Wind Redistribution on First‐Year Sea Ice

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract We present novel observations of C‐band Synthetic Aperture Radar (SAR) coherence sensitivities and patterns for snow on first‐year sea ice (FYI) consistent with snow thermodynamics and wind redistribution. Wintertime SAR coherence and backscatter change observations of landfast FYI in Dease Strait, Nunavut, Canada are made using 12‐day repeat ...

Toxicity of Natural Deep Eutectic Solvent Betaine:Glycerol in Rats [PDF]

open access: possibleJournal of Agricultural and Food Chemistry, 2018
Natural deep eutectic solvents (NaDES) are new natural solvents in green chemistry that in some cases have been shown to allow better extraction of plant bioactive molecules compared to conventional solvents and higher phenolic compound absorption in rodents. However, there is a serious lack of information regarding their in vivo safety. The purpose of

Deep eutectic solvents—Teaching nature lessons that it knew already

2021
When Brønsted and Lewis acids and bases are mixed strong hydrogen bonds develop and these deviate from ideal mixtures resulting in a significant depression of freezing point. Many of these mixtures are liquid at ambient temperatures. These so-called deep eutectic solvents have become an area of intense study since their discovery.

Natural Deep Eutectic Solvents – Solvents for the 21st Century

ACS Sustainable Chemistry & Engineering, 2014
Green technology actively seeks new solvents to replace common organic solvents that present inherent toxicity and have high volatility, leading to evaporation of volatile organic compounds to the atmosphere. Over the past two decades, ionic liquids (ILs) have gained enormous attention from the scientific community, and the number of reported articles ...

Natural deep eutectic solvent—A novel green solvent for protein stabilization

International Journal of Biological Macromolecules, 2023
Natural deep eutectic solvents (NADESs) have been explored to provide a favorable environment for protein stabilization. In this context, NADESs were prepared with the molar ratio of trehalose to betaine ranging from 1:3 to 1:9 (NADES 1-3 to NADES 1-9).

Biocatalyzed Vinyl Laurate Transesterification in Natural Deep Eutectic Solvents

Waste and Biomass Valorization, 2023
Abstract: Purpose Natural deep eutectic solvents (NADES) represent a green alternative to conventional organic solvents as reaction medium, offering more benign properties. To efficiently design NADES for biocatalysis, a better understanding of their effect on these reactions is needed.
