Revealing the Overlooked Catalytic Ability of γ-AlO: Efficient Activation of Peroxymonosulfate for Enhanced Water Treatment.

Activated alumina (γ-AlO) is one of the few nanomaterials manufactured at a ton-scale and successfully implemented in large-scale water treatment. Yet its role in advanced oxidation processes (AOPs) has primarily been limited to functioning as an inert carrier due to its inherently nonredox nature. This study, for the first time, presents the highly efficient capability of γ-AlO to activate peroxymonosulfate (PMS) for selectively eliminating electron-rich organic pollutants in the presence of Cl.

Unexpected chloride-triggered organics removal in the zirconium oxide activated peroxymonosulfate system.

Chloride ion (Cl) is ubiquitous in diverse water bodies, yet poses a longstanding challenge in water pollution control by hindering the efficiency of pollutant degradation. Herein, we proposed a novel concept involving the direct utilization of endogenous Cl ions in water for rapid water purification within a non-redox zirconium oxide (ZrO)-activated peroxymonosulfate (PMS) system. In this process, PMS was complexed on the ZrO surface through inner-sphere coordination, and effectively activated by the partial electron cloud deviation from Zr(IV) sites to PMS, thereby forming a metastable surface complex with an elevated redox potential.

Simultaneous effects of nanoscale zero-valent iron on wastewater decontamination and energy generation: Mechanisms of sulfamethoxazole degradation and methanogenesis.

The results showed that the removal of SMX in the reactor pairs with 0.

Targeted apoptosis of senescent cells by valproic acid alleviates therapy-induced cellular senescence and lung aging.

Background: Accumulation of senescent cells in tissues and their downstream effect programs have emerged as key drivers of aging and age-associated pathologies. Recent progresses in senotherapeutics indicated that either selectively killing senescent cells with senolytics or suppressing the senescence-associated secretory phenotype (SASP) secretion using senomorphics contributes to extending of the healthy lifespan and alleviating numerous age-related disorders in mice.

Purpose: However, the potential side-effects and long-term cytotoxicity of the above novel compounds have not yet been determined.

A facile strategy for the preparation of polylactide nano-microspheres with enhanced stereo-complexations.

Stereo-complexed polylactide (sc-PLA) nano-microspheres were separated by adding poor solvent to the poly(l-lactide) (PLLA)/poly(d-lactide) (PDLA) blend solution. The effects of different process parameters (concentration, processing method, ratio of PLLA/PDLA blend solution to poor solvent) on the microsphere particle size were investigated. The microscopic morphology, crystallinity, and thermal properties were investigated by Fourier transform infrared spectroscopy, differential scanning calorimetry, two-dimensional wide-angle X-ray diffraction, transmission electron microscopy and scanning electron microscopy.

Long-term and multiscale assessment of methanogenesis enhancement mechanisms in magnetite nanoparticle-mediated anaerobic digestion reactor.

Magnetite nanoparticles (FeO-NPs) have been demonstrated to be involved in direct interspecies electron transfer between syntrophic bacteria, yet a comprehensive assessment of the ability of FeO-NPs to cope with process instability and volatile fatty acids (VFAs) accumulation in scaled-up anaerobic reactors is still lacking. Here, we investigated the start-up characteristics of an expanded granular sludge bed (EGSB) with FeO-NPs as an adjuvant at high organic loading rate (OLR). The results showed that the methane production rate of R1 (with FeO-NPs) was approximately 1.

Reversible pH-Gated MXene Membranes with Ultrahigh Mono-/Divalent-Ion Selectivity.

Artificial ion channel membranes hold high promise in water treatment, nanofluidics, and energy conversion, but it remains a great challenge to construct such smart membranes with both reversible ion-gating capability and desirable ion selectivity. Herein, we constructed a smart MXene-based membrane via -phenylenediamine functionalization (MLM-PPD) with highly stable and aligned two-dimensional subnanochannels, which exhibits reversible ion-gating capability and ultrahigh metal ion selectivity similar to biological ion channels. The pH-sensitive groups within the MLM-PPD channel confers excellent reversible Mg-gating capability with a pH-switching ratio of up to 100.

Perceived social support mitigates the associations among household chaos and health and well-being in rural early adolescents.

Purpose: Previous studies have demonstrated that early adolescents residing in chaotic households experience adverse health and well-being outcomes. However, the potential protective factors that mitigate the relationship between household chaos and early adolescents' health and well-being remain unknown. Accordingly, this study aims to investigate whether perceived social support moderates the link between household chaos and the health and well-being among Chinese rural early adolescents.

The impact of climate change and human activities to vegetation carbon sequestration variation in Sichuan and Chongqing.

Exploring the vegetation carbon cycle and the factors influencing vegetation carbon sequestration in areas with complex plateau-basin topography and fragile ecosystems is crucial. In this study, spatial and temporal characteristics of carbon sequestration by vegetation in Sichuan and Chongqing from 2010 to 2020 and the influencing factors were investigated through simulations of net primary productivity (NPP) using the modified Carnegie-Ames-Stanford approach (CASA) and the Thornthwaite Memorial (TM) model and using chemical equations of photochemical reactions. The results indicated that: The spatial distribution of carbon sequestration capacity (CSC) trends showed an increase in the east (the most prominent increased trend along the mountainous areas of the basin) and a decrease in the west (western Sichuan plateau).
