Immobilized photosensitizers for antimicrobial applications [PDF]

, 2015
Photodynamic antimicrobial chemotherapy (PACT) is a very promising alternative to conventional antibiotics for the efficient inactivation of pathogenic microorganisms; this is due to the fact that it is virtually impossible for resistant strains to ...

Transannular O‐Heterocyclization Reactions of Cyclododeca‐1,5,9‐triene Derivatives: A New Concept for the Preparation of Key Intermediates for Total Syntheses of Annonaceous Acetogenins

Helvetica Chimica Acta, EarlyView.
Four stereogenic centers are formed diastereoselectively in one step from a cyclic (E,E)‐1,5‐diene system using an electrophilic addition reaction. Subsequent ozonolytic cleavage of the intact Z‐double bond, followed by intramolecular nucleophilic substitution, yields an octahydroterfurandione with a threo,cis,threo configuration, an arrangement found ...

Evaluation of fenton and ozone-based advanced oxidation processes as mature landfill leachate pre-treatments [PDF]

, 2011
Fenton treatment (Fe2+/H2O2) and different ozone-based Advanced Oxidation Processes (AOPs) (O3, O3/OH− and O3/H2O2) were evaluated as pre-treatment of a mature landfill leachate, in order to improve the biodegradability of its recalcitrant organic matter

Measuring Molecular Forces With Atomic Force Microscopy 1: Solvent Influence on Hydrophobic Interactions

Microscopy Research and Technique, EarlyView.
Atomic force microscopy enables precise evaluation of the magnitude and range of hydrophobic and van der Waals interactions. This primer presents a protocol for fluorocarbon functionalization of gold surfaces and examines how water: DMSO mixtures affect hydrophobic forces, with data interpreted through an extended van der Waals model.

PTQ10‐based organic photodetectors for visible light detection and their tolerance to impurities

Polymer International, EarlyView.
PTQ10‐based organic photodetectors were found to be very sensitive to the presence of Pd(PPh3)4 catalyst traces, impacting the transport properties and light detection capacities. Abstract PTQ10 donor polymer has attracted a lot of interest in organic optoelectronics, particularly in the field of organic photovoltaics, owing to its ease of synthesis ...

Underwater Plasma‐Driven Decomposition of Tetramethylammonium Hydroxide (TMAH) Under Different Applied Field Strengths

Plasma Processes and Polymers, EarlyView.
Underwater plasma efficiently degrades TMAH via in situ generation of reactive oxygen and nitrogen species. An underwater plasma accelerates mass transfer and radical attack on the quaternary ammonium cation. Time‐resolved analyses show decreasing TOC and conversion of organic carbon toward inorganic species, with concomitant formation of NO3–/NH4+ at ...

Contaminants of emerging concern in agricultural soils: Current understanding, overlooked issues, and future priorities

PLANTS, PEOPLE, PLANET, EarlyView.
Contaminants of emerging concern (CECs) in agriculture represent a growing global challenge for food safety and public health. In this review, we synthesized evidence on how substances such as pharmaceuticals, microplastics, and per‐ and polyfluoroalkyl substances (PFAS) enter soils, accumulate in crops, and affect ecological and human health. We found
