Vacancies and sea urchin structure protect cobalt manganese spinel from anion poisoning in peroxymonosulfate activation

open access: yesnpj Clean Water
Peroxymonosulfate (PMS) activation by cobalt manganese spinel (Co-Mn) is always unsatisfactory due to the interference of co-existing anions in water.

Particle Size-Dependent Monthly Variation of Pollution Load, Ecological Risk, and Sources of Heavy Metals in Road Dust in Beijing, China

open access: yesToxics
Road dust carries various contaminants and causes urban non-point source pollution in waterbodies through runoff. Road dust samples were collected in each month in two years and then sieved into five particle size fractions.

Turning Humidity Into Function: Heterojunction Interfaces for Dual‐Mode Removal of Nonpolar Vapors

open access: yesAdvanced Materials Interfaces, EarlyView.
A wire‐grown MIL–88B(Fe)@Fe3(PO4)2 heterojunction converts ambient humidity into a functional mediator for nonpolar VOC purification. Water forms a hydration layer that enhances cyclohexane uptake while simultaneously promoting •OH generation, resulting in synergistic adsorption–photocatalysis under humid conditions.

An integrated approach to indoor contaminant modelling [PDF]

open access: yes, 2006
Air pollutants are those chemicals that are not generally present in the atmosphere because of natural causes but are disseminated into the air by human activity. In most parts of Europe, outdoor pollutants are principally the products of combustion from

CircRNA_1156 Attenuates Neodymium Nitrate-Induced Hepatocyte Ferroptosis by Inhibiting the ACSL4/PKCβII Signaling Pathway

open access: yesAntioxidants
Ferroptosis, a form of regulated cell death driven by lipid peroxidation, has been implicated in the pathogenesis of liver diseases. This study investigates the role of circRNA_1156 in neodymium nitrate (Nd(NO3)3)-induced hepatocyte ferroptosis.

Defect‐Driven Charge Separation in Ba‐Doped SrTiO3: Correlating Photoelectrochemical Performance With Dye‐Selective Photocatalysis

open access: yesAdvanced Materials Interfaces, EarlyView.
Ba‐doped SrTiO3 perovskites establish a direct correlation between photoelectrochemical activity and photocatalytic performance. Optimized Ba0.5Sr0.5TiO3 exhibits enhanced charge separation, photocurrent generation, and visible‐light‐driven dye degradation through defect‐induced oxygen vacancies and lattice distortion.
