Electrochemical CO2 Reduction on a Bi–Sn Eutectic Alloy in Acidic Media for Formic Acid Production

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
Acidic CO2 electrolysis enables direct formic acid production with minimal (bi)carbonate formation. A eutectic Bi–Sn gas‐diffusion electrode achieves 81.3% faradaic efficiency (FE) at −100 mA cm−2 and pH 3, retaining selectivity up to −400 mA cm−2 and stable operation for 100 h with < 10% FE loss.

Comment on 'Enhancement in the production of nucleating clusters due to dimethylamine and large uncertainties in the thermochemistry of amine-enhanced nucleation' by Nadykto et al., Chem. Phys. Lett., 609, 42-49 (2014)

, 2014
We comment on a study by Nadykto et al. recently published in this journal. Earlier work from our group has been misrepresented in this study, and we feel that the claims made need to be amended. Also the analysis of Nadykto et al.

Probabilistic performance estimators for computational chemistry methods: Systematic Improvement Probability and Ranking Probability Matrix. I. Theory

, 2020
The comparison of benchmark error sets is an essential tool for the evaluation of theories in computational chemistry. The standard ranking of methods by their Mean Unsigned Error is unsatisfactory for several reasons linked to the non-normality of the ...

Extraction and Optimization of Fucoidan From Sargassum muticum Using Acidic Eutectic Solvents and Evaluation of Their Effects on Fibroblast Cell Lines

ChemistryOpen, Volume 15, Issue 4, April 2026.
Fucoidan, a sulfated polysaccharide extracted from the cell wall of macroalgae such as S. muticum, exhibits promising biological properties. This study investigated a green extraction using deep eutectic solvents (DESs), with an emphasis on process optimization and bioactive evaluation of fucoidan.

A universal chemical potential for sulfur vapours [PDF]

, 2015
The unusual chemistry of sulfur is illustrated by the tendency for catenation. Sulfur forms a range of open and closed S$_n$ species in the gas phase, which has led to speculation on the composition of sulfur vapours as a function of temperature and ...
