Fluorine‐Free Ionic Liquid Electrolytes Featuring Biomass‐Derived Heterocyclic Anions for Variable Temperature Supercapacitors

Advanced Energy and Sustainability Research, Volume 7, Issue 2, February 2026.
This study introduces two new fluorine‐free ionic liquids (ILs) produced by coupling biomass‐derived heterocyclic anions, i.e., THP and 3‐FuA, with P4444 cation. Both the ILs display enhanced capacitance with increasing temperature, underscoring their potential as fluorine‐free electrolytes for supercapacitors.

Synthesis of α‐Pentafluorosulfanylated‐β2,3‐Amino Esters

ChemistryEurope, Volume 4, Issue 2, February 2026.
De novo α‐SF5‐β2,3‐amino esters are now accessible through a straightforward aza‐Michael reaction using a series of newly developed (E)‐α‐SF5‐α,β‐unsaturated esters. Two new, highly functionalized, contiguous tertiary stereocenters are formed with diastereodivergence governed by the choice of solvent and/or base.

19F NMR as a Molecular Reporter: Labelling Strategies and Methods for Probing Biomolecular Motion and Exchange

Chemistry–Methods, Volume 6, Issue 2, February 2026.
This review summarizes the unique benefits 19F NMR spectroscopy has to offer for the study of biological systems. Particular focus is laid on the available strategies for incorporation of fluorinated probes into proteins and the latest applications of the ever‐expanding toolbox of fluorine NMR methodology to study structure and dynamics.

Microbial metabolites in tumor epigenetic regulation

iMeta, Volume 5, Issue 1, February 2026.
The gut microbiome modulates tumor epigenetic regulation through bioactive metabolites derived from dietary substrates. Microbiota‐produced SCFAs, secondary BAs, one‐carbon metabolites, and tryptophan‐derived ligands regulate histone acetylation, DNA methylation, and chromatin remodeling via HDAC, DNMT, AhR, and metabolic cofactor‐dependent pathways ...

Systemic Toxicity of L‐Mimosine in Rabbits: A Non‐Rodent Model for Safety Assessment

Journal of Applied Toxicology, Volume 46, Issue 2, Page 639-651, February 2026.
ABSTRACT L‐mimosine is a non‐protein amino acid primarily found in the Mimosoideae subfamily, with high concentrations in Leucaena leucocephala and Mimosa pudica. These plants are widely used in both human and animal nutrition, as well as in phytotherapeutic applications. While the toxic effects of L‐mimosine have been extensively studied in ruminants,
