Synergistic Effect on Enhanced Oil Recovery in High Salinity Carbonate Reservoirs Using a Novel PEI‐Functionalized Carbon Nanotube Nanocomposite

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...

ISAba1‐mediated crp‐osmC amplification enhances host‐associated fitness in Acinetobacter baumannii

mLife, EarlyView.
Abstract Acinetobacter baumannii is a pathogen, highly adaptable to both hospital‐ and host‐associated environments. Understanding the genetic mechanisms underlying its adaptability is critical for controlling its persistence. Our study identified the crp‐osmC gene cluster, flanked by ISAba1 elements, as a significant genetic structure undergoing ...

The toxicity of the quaternary ammonium compound benzalkonium chloride alone and in mixtures with other anionic compounds to bacteria in test systems with Vibrio fischeri and Pseudomonas putida

Ecotoxicology and Environmental Safety, 2008
Mixtures of chemicals are present in the aquatic environment but standard testing methods assess only single compounds. One aspect of this question is the importance of the formation of ionic pairs, for example from quaternary ammonium compounds with organic anions, and the significance of the ionic pairs for bacterial toxicity in the aquatic ...

Benzalkonium Chloride in Eye Drops Causing Allergic Contact Dermatitis: A Case Series

Australasian Journal of Dermatology, EarlyView.
ABSTRACT We present three patients who developed allergic contact dermatitis (ACD) from benzalkonium chloride (BAK) in ophthalmic drops. BAK is a preservative commonly found in ophthalmic formulations and there is a rising trend of ACD to this allergen. The irritant and sensitising properties of BAK on the ocular mucosa will be discussed.
