Experimental Kinetic Study of the Reactions of Hydroxyl Radicals With Three Oxymethylene Ethers and With 1,3,5‐Trioxane, Tetrahydrofuran, and Tetrahydrofuran‐d8

open access: yesInternational Journal of Chemical Kinetics, Volume 57, Issue 8, Page 497-506, August 2025.
ABSTRACT Polyoxymethylene dimethyl ethers, CH3O(CH2O)nCH3 with n ≥ 1 (abbreviated in the literature also as OME‐n, PODEn, POMDMEn, or OMDMEn) are currently discussed as renewable fuels. Despite fuel + OH reactions are crucial for the combustion chemistry and atmospheric degradation of fuels, experimental kinetic data on OME‐n + OH do not exist in the ...

Einfluss von Tensiden auf spontane Tropfenladung

open access: yesAngewandte Chemie, Volume 137, Issue 31, July 28, 2025.
Wassertropfen, die sich über eine hydrophobe Oberfläche bewegen, laden sich elektrisch auf. Diese spontane Aufladung kann durch Zugabe von Tensiden reduziert oder sogar verhindert werden. Abstrakt Wassertropfen akkumulieren spontan Ladungen, wenn sie sich auf hydrophoben dielektrischen Oberflächen bewegen.

Biomineralization‐Inspired Membranization Toward Structural Enhancement of Coacervate Community

open access: yesAdvanced Science, Volume 12, Issue 18, May 15, 2025.
The spontaneous formation of a mineralized membrane on the surface of coacervate droplets is facilitated by Fe3+ ions and redox reaction, accompanied by the aggregation of the coacervate droplets. These membranized coacervate assemblages not only retain the capacity for biomolecule sequestration and enzyme catalysis but also exhibit enhanced structural

Precipitation of Insulin with Rhodamine-B

open access: yesExperimental Biology and Medicine, 1939
A few years ago one of the authors in unpublished results showed that rhodamine-B would precipitate pepsin from solution. Since the well known proteolytic ferment precipitating agent, safranine, also precipitates insulin,1 it was decided to determine if rhodamine-B would precipitate insulin and if so, whether the dye could be removed without ...
