Modulating Iron Crystals with Lattice Chalcophile‐Siderophile Elements for Selective Dechlorinations Over Hydrogen Evolution

Advanced Science, Год журнала: 2025, Номер unknown

Опубликована: Март 7, 2025

Selective dechlorination of organic chlorides over hydrogen evolution reaction (HER) remains a challenge because their coincidence. Nanoscale zerovalent iron (nFe0) draws promising picture in situ groundwater dechlorination, but its indiscriminate reactivity limits the application. Here, nFe0 crystals are designed with electron shuttles and improved hydrophobic nature based on elemental chalcophile-siderophile characteristics, where S served as bridge to allow impregnating weakly siderophile strongly chalcophile Cu. Even impregnations lattice elements into evidenced at both intraparticle individual-particle levels. The modulated Fe microenvironment physicochemical properties broke reactivity-selectivity-longevity-stability trade-off. Compared nFe0, superhydrophobic Cu─S─nFe0 expansion promoted by 20-fold inhibited HER 150-fold, utilizing ≈80-100% electrons from Fe0 reservoir. This work demonstrates concept engineering tunable structure-property relationships, mimicking reductive dehalogenases selectively interacting halocarbon functional groups for efficient dehalogenation sustainable remediation.

Impregnating Lattice Sulfur into Iron Crystal Allows Anaerobic Degradation of Extracellular Antibiotic Resistance Genes

Small, Год журнала: 2025, Номер unknown

Опубликована: Март 13, 2025

Abstract Lattice sulfur‐impregnated nanoscale zerovalent iron (S‐nFe 0 ) has been recognized as a promising groundwater remediation agent. However, little information is available on its reactivity with ubiquitous extracellular antibiotic resistance genes (eARGs) in anaerobic groundwater, and how S content speciation affect their interactions. Here, the efficient degradation of eARGs by S‐nFe (6 log within 5 min), resulting completely inhibited transformation showed. The removal rate (0.26 mg m −2 min −1 correlated well S‐induced hydrophobicity electron transfer ability materials, this improvement (up to 22‐fold) compared nFe largely depended speciation. Multiple measurements are applied verify interactions where Fe−O−P coordination, hydrophobic interaction, play critical roles. application potential strongly supported long‐term stability real universal multiple eARGs. These findings elucidate mechanistic role lattice , unveil binding sites between will advance understanding toward better design S‐nFe° for eARGs‐contaminated remediation.

The Association Between Per- and Polyfluoroalkyl Substances Exposure and Thyroid Hormones in Men and Non-Pregnant Women: A Systematic Review and Meta-Analysis

Toxics, Год журнала: 2025, Номер 13(3), С. 214 - 214

Опубликована: Март 14, 2025

Studies have shown that per- and polyfluoroalkyl substances (PFAS) may impact thyroid function in human health. While the consistency between PFAS exposure health effects pregnant women has been validated, on men non-pregnant remains inconclusive. To address this, a meta-analysis was carried out this paper, with 14 eligible studies retrieved from Embase, PubMed, Web of Science were published up to 2 June 2024, focusing relationship its effect hormone levels body. The indexes analyzed included stimulating (TSH), triiodothyronine (T3), thyroxine (T4), free T3 (FT3), T4 (FT4). estimated value (β) corresponding confidence interval (95% CI) extracted literature.
