Tungsten sulfide sheets with tunable layered structures: Piezocatalysis via multi-channels to generate HO.

Driven by the urgent need for eco-friendly, safe and facile production processes for hydrogen peroxide (HO), piezocatalysis shows significant potential due to its accessible energy supply and capacity for on-site HO preparation. Owing to their tunable surface properties and unique electronic structures, transition metal dichalcogenides (TMDCs) are regarded as promising piezocatalysts. Nevertheless, the uneven distribution of active sites, poor stability, and restricted electron transport capabilities hinder the further improvement of their piezocatalytic performance.

A Biomimetic Soft Actuator Achieves Efficient Fluorescence via Covalent Cross-Linking.

The bioluminescence mechanisms of deep-sea organisms provide innovative ideas for biomimetic design. To meet the detection needs in low-light deep-sea environments, the development of soft robots with high-brightness luminescence is crucial for long-term in situ observation. Directly incorporating high-performance fluorescent molecules into hydrogel matrices presents challenges: fluorescent molecules tend to dissociate in physically crosslinked systems, and complex aqueous environments may lead to instability in the material structure.

Metal-Support Interaction Induced Electron Localization in Rationally Designed Metal Sites Anchored MXene Enables Boosted Electromagnetic Wave Attenuation.

The electron localization is considered as a promising approach to optimize electromagnetic waves (EMW) dissipation. However, it is still difficult to realize well-controlled electron localization and elucidate the related EMW loss mechanisms for current researches. In this study, a novel two-dimensional MXene (TiCT) nanosheet decorated with Ni nanoclusters (Ni-NC) system to construct an effective electron localization model based on electronic orbital structure is explored.

Simulated sunlight-enhanced peroxymonosulfate activation via S-scheme BiOBr/g-CN aerogel heterojunction for multi-pollutant remediation: Band structure and interface engineering.

The intricate composition of real-world aquatic systems significantly constrains the improved overall performance of powder catalysts, meanwhile their recyclability is inferior to the bulk counterparts (e.g. aerogels).

Polymorphic relaxor phase and defect dipole polarization co-reinforced capacitor energy storage in temperature-monitorable high-entropy ferroelectrics.

Energy storage high-entropy ceramics are famous for their ultrahigh power density and ultrafast discharge rate. However, achieving a synchronous combination of high energy density and efficiency along with intelligent temperature-monitorable function remains a significant challenge. Here, based on high-entropy strategy and phase field simulation, the polarization response of domains in BiNaTiO-based ceramics is optimized by constructing a concomitant nanostructure of defect dipole polarization and a polymorphic relaxor phase.

Delayed pneumocephalus induced by repeated percutaneous aspiration after spinal surgery: A case report and literature review.

Rationale: Severe tension pneumocephalus can lead to drowsiness, coma, and even brain hernia and death. The occurrence of delayed pneumocephalus after spinal surgery is rarely reported and often ignored. Herein, we report a case of delayed pneumocephalus after repeated percutaneous aspiration following spinal surgery.

A disease progression prediction model and nervous system symptoms in coronavirus disease 2019 patients.

This study aimed to investigate factors affecting coronavirus disease 2019 (COVID-19) progression, also to explore the clinical features and prognosis of nervous system symptom (NSS) involved COVID-19 patients. 417 COVID-19 patients were analyzed in this retrospective study, and they were clinically classified as severe patients and non-severe patients. According to NSS involved status, COVID-19 patients were further divided into NSS patients and non-NSS patients.
