A method is described for the confirmation of chlorophenols in human urine. A hydrolyzed urine sample is analyzed by both gas chromatography (GC), and liquid chromatography (LC) with electrochemical detection and the results compared. A discussion of these results, including factors affecting separation, detection, and confirmation of chlorophenols in human urine, is included.

Electrocatalytic dehalogenation is a promising method for the remediation of chlorinated organic pollutants. The dehalogenation performance is controlled by catalytic activity, and the underlying electrocatalytic dehalogenation mechanisms need to be carefully investigated for guiding the design of catalyst. Here we report the preparation of a new Pd-based catalyst with a nanosheet structure (Pd NS) by a simple wet-chemical reduction method.

A series of Ag-loaded and oxygen vacancy (OV)-containing BiOBr/BiOI (Ag/BiOBr/BiOI) photocatalysts with varying Ag loading levels were synthesized via the solvothermal-photocatalytic reduction method. As confirmed via optical, photoelectrochemical, and 4-chlorophenol photodegradation experiments, a low Ag loading level significantly enhanced the photogenerated charge carrier (PCC) transfer on the BiOBr/BiOI semiconductor surface and the performance of Ag/BiOBr/BiOI photocatalysts, which was attributable to the synergism between the effect of OVs and the localized surface plasmon resonance (LSPR) of Ag nanoparticles. Additionally, BiOBr/BiOI heterojunctions facilitated efficient visible-light harvesting and PCC separation.

Objective: The objective of this study was to explore the financial consequences of adopting cenobamate as a treatment alternative in epilepsy patients with drug-resistant focal onset seizures (FOS) from a societal perspective in the Netherlands.
Methods: A previous budget impact model with a 5-year time horizon was adapted to the Dutch setting accounting for the eligible population, real-world market shares, treatment effectiveness and resource use in two scenarios: cenobamate with constant market share versus cenobamate with linearly increased market share up to 20%. Clinical inputs included treatment response, seizure reduction and adverse events.

Nanozymes, as promising alternatives to natural enzymes, offer several advantages with biocatalytic functions but remain inferior in catalytic activity. It is crucial to focus on factors that affect the enzymatic activity of nanozymes and develop strategies to make them more competitive with natural enzymes. Herein, CuVO nanorods are confirmed to own the intrinsic laccase-like activity, and an acetonitrile (MeCN)-mediated strategy is proposed for reaction acceleration by mimicking the enzymatic substrate pocket.
