Effect of sludge-based biochar on the stabilization of Cd in soil: experimental and theoretical studies.

Soil heavy metal contamination and sludge disposal have become globally environmental issues problems of great concern. Utilizing sludge pyrolysis to produce biochar for remediating heavy metal-contaminated soil is an effective strategy to solve these two environmental problems. In this study, municipal sewage sludge and papermaking sludge were used as feedstock to prepare co-pyrolyzed biochar, which was then applied to reduce the toxicity of Cd in soil.

Sleep structure of short-term insomnia disorder with mild cognitive impairment in older adults and their correlation with cognitive function: a case-control study.

Objectives: This study seeks to delineate the sleep architecture characteristics in older adults with short-term insomnia and mild cognitive impairment (MCI) and to explore their association with cognitive performance.

Methods: Ninety elderly individuals with short-term insomnia were enrolled and stratified into two cohorts based on their Montreal Cognitive Assessment (MoCA) scores: the Short-Term Insomnia Group (STID) comprising 35 participants and the Short-Term Insomnia with Cognitive Impairment Group (STID-MCI) with 55 participants. Demographic data, Pittsburgh Sleep Quality Index (PSQI), MoCA, Hamilton Depression Rating Scale (HAMD-17), Hamilton Anxiety Rating Scale (HAMA), and polysomnography (PSG) parameters were compared between groups.

Extracellular HSP70 facilitated β-glucan induced trained immunity in macrophages to suppress sepsis via TLR2-NF-κB axis.

Sepsis is a common systemic infectious disease followed by extremely high incidence and mortality with no effective treatment and clinical drugs. As a key mediator involved in infection and immunity, it has been reported that sepsis patients are accompanied by increased heat shock protein 70 (HSP70). Trained immunity is a novel innate immunity approach that can be activated by β-glucan to fight against sepsis.

Nanofibrous Ru/SnO heterostructure as robust bifunctional electrocatalyst for high-performance overall hydrazine splitting and Zn-hydrazine battery.

Water electrolysis represents a green and efficient strategy for hydrogen (H) production. However, the four-electron transfer process involved in its anodic oxygen evolution reaction (OER) half-reaction restricts the H generation rate. Employing hydrazine oxidation reaction (HzOR) as a substitute for OER in H generation can dramatically reduce energy consumption.
