Chlorothiophenols are key precursors for polychlorinated dibenzothiophenes, which are a class of persistent organic pollutants environmentally, but little is known about their electronic and spectroscopic properties. We report a high-resolution spectroscopic investigation of the cryogenically cooled 2-chlorothiophenoxide (2-CTP) anion using photoelectron imaging, photodetachment spectroscopy, and resonant photoelectron spectroscopy. High-resolution photoelectron spectroscopy yields an accurate electron affinity of 21,005 ± 5 cm (2.

Bisphenol A (BPA) is a persistent organic pollutant with toxic effects on human health and ecosystems. In this study, the performance of MWCNT-OH functionalized with iron nanoparticles (MWCNT-OH@Fe) using sugarcane bagasse extract as a reducing agent (green synthesis) was evaluated for BPA adsorption. The kinetics are fast, between 10 and 20 min in the range of concentrations evaluated and the resistance to external film diffusion (external film mass transfer) identified as the rate-limiting step of the process.

With the rapid advancement of communication technologies, issues of electromagnetic pollution and electromagnetic compatibility have become increasingly severe, heightening the demand for high-performance electromagnetic wave absorption materials. Metal-organic frameworks (MOFs) have flourished in this field owing to their chemical tunability, high porosity, tailored topological structures, and functionality. MOF-derived composites exhibit diverse loss mechanisms and heterogeneous structures, achieving lightweight, broadband, and highly efficient absorption.

Diabetic wounds present persistent challenges due to impaired healing, recurrent infection, oxidative stress, and dysregulated glucose metabolism. Bioinspired polymeric microneedle (MN) patches have emerged as multifunctional platforms capable of penetrating the stratum corneum to deliver therapeutics directly into the dermis, enabling glucose regulation, antimicrobial action, reactive oxygen species (ROS) modulation, and proangiogenic stimulation. Recent experimental evidence has demonstrated that the integration of glucose oxidase-loaded porous metal-organic frameworks, photothermal nanomaterials, and antioxidant hydrogels within dissolvable MNs achieves synergistic bactericidal effects, accelerates collagen deposition, and enhances neovascularization in diabetic wound models.

Background And Aim: Hospital effluents are a major source of environmental contaminants, harboring pathogenic bacteria, toxic trace metals, and high organic loads. This study aimed to evaluate the bacteriological and physicochemical profiles of wastewater discharged from three coastal hospitals in Oran, Algeria, and to assess the associated public and livestock health risks under the One Health approach.
Materials And Methods: A cross-sectional study was conducted from January 2023 to February 2024, involving monthly sampling at three hospitals and one drainage collector.
