Influence of Polymeric Dispersants on the Dissolution Rate of Tricalcium Silicate and the Nucleation of Calcium‐Silicate‐Hydrate and Portlandite

open access: yesChemistry – A European Journal, Volume 31, Issue 27, May 14, 2025.
Comb‐copolymers with anionic functional groups and poly(ethylene glycol) side chains are concrete dispersants. However, they retard the hydration of the main Portland cement phase Ca3SiO5${\rm Ca}_{3}{\rm S}{\rm iO}_{5}$. Herein, we report on their influence on the dissolution rate of Ca3SiO5${\rm Ca}_{3}{\rm S}{\rm iO}_{5}$ and their nucleation ...

A Pseudomonas putida efflux pump acts on short-chain alcohols

open access: yesBiotechnology for Biofuels, 2018
Background The microbial production of biofuels is complicated by a tradeoff between yield and toxicity of many fuels. Efflux pumps enable bacteria to tolerate toxic substances by their removal from the cells while bypassing the periplasm.

Impact of malodour on health‐related quality of life of patients with chronic wounds due to volatile organic compounds

open access: yesWound Repair and Regeneration, Volume 33, Issue 3, May/June 2025.
Abstract Chronic wounds significantly impact health‐related quality of life (HRQoL). Unpleasant wound odour, caused by bacterial colonisation and necrotic processes, is a distressing symptom. Its exact composition is not well understood, but it could be the basis for a personalised odour avoidance strategy. Therefore, this feasibility study explored 92
