13C-NMR Spectroscopic Study of the Kinetics of Formaldehyde Oligomerization Reactions in the System (Formaldehyde + Water + Isoprenol)

open access: yesIndustrial & Engineering Chemistry Research, 2021
Isoprenol (3-methyl-3-buten-1-ol) is an important intermediate in the chemical industry, which is used, for example, in the production of citral. It is produced from aqueous formaldehyde and isobutene and has to be separated from mixtures containing formaldehyde and water in the purification process, which is complicated, as formaldehyde is highly ...

PplD Is a De-N-Acetylase of the Cell Wall Linkage Unit of Streptococcal Rhamnopolysaccharides [PDF]

open access: yes, 2022
The cell wall of the human bacterial pathogen Group A Streptococcus (GAS) consists of peptidoglycan decorated with the Lancefield group A carbohydrate (GAC). GAC is a promising target for the development of GAS vaccines. In this study, employing chemical,

Dynamic interplay of multidrug transporters with TolC for isoprenol tolerance in Escherichia coli [PDF]

open access: yesScientific Reports, 2015
AbstractEngineering of efflux pumps is a promising way to improve host’s tolerance to biofuels such as medium-chain alcohols (CmOHs); however, this strategy is restricted by poor understanding of the efflux pumps engaged in extrusion of solvents. In this study, several Escherichia coli mutants of multidrug transporters were evaluated for isoprenol ...

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 ...

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

Neuroprotection by Drugs, Nutraceuticals and Physical Activity [PDF]

open access: yes, 2023
Acute and chronic neural injuries, including stroke, brain trauma and neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), Parkinson's disease (PD), and Alzheimer's disease (AD) are associated with high ...

Enzyme‐Catalysed Formation of Hydrocarbon Scaffolds from Geranylgeranyl Diphosphate Analogs with Shifted Double Bonds

open access: yesChemistry – A European Journal, Volume 31, Issue 23, April 22, 2025.
Four new geranylgeranyl diphosphate analogs with shifted double bonds were synthesized and together with the known analog iso‐GGPP I converted with 14 diterpene synthases. While two substrate analogs were not accepted by the enzymes, the other three analogs yielded compounds with skeletons that are not observed in nature.

Effect of Polyoxyethylene-Based Nonionic Surfactants on Chemical–Mechanical Polishing Performance of Monocrystalline Silicon Wafers

open access: yesCrystals
The use of surfactants is crucial in the chemical–mechanical polishing fluid system for silicon wafers. This paper examines the impact of the functional group structure of polyoxyethylene-based nonionic surfactants and the variation in the ...
