Electrochemical Reactors for Continuous Decentralized H₂O₂ Production

Angewandte Chemie International Edition, Год журнала: 2022, Номер 61(35)

Опубликована: Июнь 14, 2022

Abstract The global utilization of H 2 O is currently around 4 million tons per year and expected to continue increase in the future. mainly produced by anthraquinone process, which involves multiple steps terms alkylanthraquinone hydrogenation/oxidation organic solvents liquid–liquid extraction . energy‐intensive environmentally unfriendly process does not meet requirements sustainable low‐carbon development. electrocatalytic two‐electron (2 e − ) oxygen reduction reaction (ORR) driven renewable energy (e.g. solar wind power) offers a more economical, low‐carbon, greener route produce However, continuous decentralized electrosynthesis still poses many challenges. This Minireview first summarizes development devices for electrosynthesis, then introduces each component, assembly some optimization strategies.

Chlorination-induced spread of antibiotic resistance genes in drinking water systems

Water Research, Год журнала: 2025, Номер 274, С. 123092 - 123092

Опубликована: Янв. 4, 2025

Chlorine, the most widely utilized disinfectant for drinking water globally, has recently been implicated in facilitating spread of antibiotic resistance genes (ARGs), raising concerns about its underestimated environmental and ecological risks. However, given current fragmented research focus results, a comprehensive understanding potential mechanisms influencing factors behind chlorination-promoted ARGs transmission systems is crucial. This work first to systematically review variations abundance, mechanisms, factors, mitigation strategies related during chlorination process. The results indicated that could induce genetic mutations promote horizontal gene transfer through multiple pathways, including increased reactive oxygen species, enhanced membrane permeability, stimulation SOS response, activation efflux pumps. In addition, this delves into significant discoveries regarding affecting ARG water, such as chlorine concentration, reaction time, disinfection byproducts, pipe materials, biofilms, matrix. A series effective from source point-of-use were proposed aimed at mitigating risks system. Finally, we address existing challenges outline future directions overcome these bottlenecks. Overall, aims advance our role dissemination inspire innovative ideas optimizing techniques, minimizing transmission, enhancing safety water.

In Vitro Evaluation of the Ultraviolet Ceed Mobile Disinfection Device: A Rapid, Portable Approach for Surface Sterilization

Cureus, Год журнала: 2025, Номер unknown

Опубликована: Март 15, 2025

Introduction: Ultraviolet-C (UVC) sterilization technologies have garnered significant attention for their potential to inactivate pathogens. The UVCeed device, a smartphone-enabled UVC tool, offers portable and user-friendly option disinfection. This study investigates the disinfection efficacy of against bacterial viral pathogens, including Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, SARS-CoV-2. Methods: Pathogens were inoculated onto sterile surfaces such as urine cups (bacteria) or glass slides (virus) exposed device at controlled distances (65 mm, 100 165 mm) durations ranging from 0 64 seconds. Laboratory conditions standardized 72°F 40-50% relative humidity. Assessment methods included viable plate counts colonies cytopathic effect (CPE) measurements SARS-CoV-2 using Vero E6 cell cultures. Crystal violet staining confirmed viability post-exposure. Key metrics, log reductions in pathogen concentration, calculated quantify efficacy. Results: achieved reductions, with exceeding 6.0 pneumoniae after seconds 65 mm. For SARS-CoV-2, concentrations decreased by over four log-units within same exposure time. Threshold times effective varied distance, shorter achieving faster. Compared Lysol® wipes, which required up minutes wetness similar effectiveness, disinfected 6"x 6" surface ~15 an 8"x 8" ~37 Discussion: These results highlight UVCeed's efficiency rapid solution. Its ability pathogens makes it valuable alternative chemical disinfectants, especially high-touch surfaces. device's distance time, underscoring importance proper usage. Future research should explore real-world applications expand testing validate these findings further.
