Metal–Organic Frameworks Based on Copper and Dicarboxy‐Functionalized Imidazole Modified With Halides: Enhancement of Catalysis in Organic Synthesis

Applied Organometallic Chemistry, Volume 38, Issue 11, November 2024.
This study enhanced copper‐based metal–organic frameworks (MOFs) by incorporating chloride and bromide, leading to improved catalytic properties. These halide‐modified MOFs exhibited increased microcrystallinity and superior performance in organic reactions, such as styrene oxide ring opening and the Friedländer reaction, demonstrating enhanced Lewis ...

Noninvasive skin swab analysis detects environmental drug exposure of pharmacy staff

Clinical and Translational Science, Volume 17, Issue 10, October 2024.
Abstract The skin is complex with multiple layers serving protective, regulatory, and detective functions. The skin hosts chemicals originating from consumption, synthesis, and the environment. Skin chemicals can provide insight into one's daily routine or their level of safety in a work environment.

Electrospun Polymeric Nanofibers for Malaria Control: Advances in Slow‐Release Mosquito Repellent Technology

Macromolecular Materials and Engineering, Volume 309, Issue 8, August 2024.
Recent developments in mosquito‐repellent textiles fabricated using the electrospinning method are reviewed. Electrospinning technology is shown to be a remarkably facile method to fabricate polymeric nanofiber‐based repellents. Electrospun polymeric nanofibers delay the release rate of the repellent.

Percutaneous Absorption of Topical N , N -Diethyl- m -Toluamide (Deet): Effects of Exposure Variables and Coadministered Toxicants [PDF]

Journal of Toxicology and Environmental Health, Part A, 2003
Exposure to N,N-diethyl-m-toluamide (DEET) commonly occurs in the general population and has been implicated as a contributory factor to the Gulf War Illness. The focus of the present studies was to determine the effect of coexposure factors, potentially encountered in a military environment, that could modulate transdermal flux of topically applied ...

Studying the adsorption of emerging organic contaminants in zeolites with dispersion‐corrected density functional theory calculations: From numbers to recommendations

ChemistryOpen, Volume 13, Issue 7, July 2024.
The performance of 13 dispersion‐corrected density functional theory methods is compared systematically for adsorption energy calculations of emerging organic contaminants in all‐silica zeolites . While qualitative trends are similar, large differences in absolute values are observed.

DEET occurrence in wastewaters: Seasonal, spatial and diurnal variability - mismatches between consumption data and environmental detection

Environment International, 2019
DEET (N, N-diethyl-m-toluamide) is one of the most frequently detected trace organic contaminants (TOrC) in wastewaters and is used primarily as an insect repellent. It was introduced for use in the general public in 1957.
