What Is the Mechanism by which the Introduction of Amorphous SeO Effectively Promotes Urea-Assisted Water Electrolysis Performance of Ni(OH)?

Nickel hydroxide (Ni(OH)) is considered to be one of the most promising electrocatalysts for urea oxidation reaction (UOR) under alkaline conditions due to its flexible structure, wide composition and abundant 3D electrons. However, its slow electrochemical reaction rate, high affinity for the reaction intermediate *COOH, easy exposure to low exponential crystal faces and limited metal active sites that seriously hinder the further improvement of UOR activities. Herein it is reported electrocatalyst composed of rich oxygen-vacancy (O) defects with amorphous SeO-covered Ni(OH) (O-SeO/Ni(OH)).

Geographical impact on the distribution of polycyclic aromatic hydrocarbons (PAHs) in hilly terrain topsoil: A case study at Chongqing, SW, China.

The distribution and transport of polycyclic aromatic hydrocarbons (PAHs) in urban environments are influenced by both anthropogenic sources and natural landscape features. While previous research has primarily focused on human activities as drivers of PAH pollution, the role of terrain-especially in cities with complex topographies-remains underexplored. To investigate the effect of terrain features on PAH distribution and transport, we analyzed topsoil samples evenly distributed in Chongqing, a city with hilly terrain (elevation: 48-2300 m).

[Integrated evidence chain: a new strategy and methodology for effectiveness e valuation of traditional Chinese medicines].

The evaluation of the effectiveness of traditional Chinese medicine(TCM) has long been a "bottleneck" issue that restricts the healthy development and internationalization of TCM. This article systematically analyzes the differences in diagnostic and treatment principles, material composition, new drug development pathways, efficacy cognition, and evaluation methodology between Chinese and Western medicine from the underlying logic of medical perspective. On this basis, it integrates the evidence elements of clinical experience, experimental research, and clinical trials, and for the first time proposes and establishes a new strategy and methodology for the evaluation of the effectiveness of TCM: the integrated evidence chain-based effectiveness evaluation of traditional Chinese medicine(iEC-Eff), forming an integrated evaluation and confirmation model of "clinical experience-experimental research-clinical trial" for the effectiveness of TCM.

Crystal OH mediating pathway for hydrogen peroxide production via two-electron water oxidation in non-carbonate electrolytes.

Water oxidation presents a promising avenue for hydrogen peroxide (HO) production. However, the reliance on alkaline bicarbonate electrolytes as an intermediate has limitations, such as HO decomposition and a narrow pH effectiveness range (7-9), restricting its utility across wider pH ranges. This study unveils a crystal OH mediating pathway that stabilizes SOOH* as a crucial intermediate.

Probiotic nanovesicles encapsulating baicalin: a strategy to overcome colorectal cancer.

Escherichia coli Nissle 1917 (EcN) is a unique probiotic utilized to treat inflammatory bowel disease and irritable bowel syndrome. Outer membrane vesicles (OMVs) from EcN can not only deliver pro-biotic anti-inflammatory molecules to cancer cells to exert anti-rectal cancer effects, but also deliver therapeutic drugs, genes, and other "cargoes" encapsulated in the vesicles to specific cells, making them an ideal vehicle for drug delivery. In this study, we successfully isolated OMVs of probiotic origin and obtained BCN-OMVs by encapsulating baicalin (BCN) in EcN-OMVs.

Case report: targeted therapy of malignant pleural mesothelioma with anaplastic lymphoma kinase receptor tyrosine kinase gene fusion mutation by crizotinib.

Malignant mesothelioma is a rare highly invasive tumour originating from the mesothelial cells of the pleura, peritoneum and pericardium. Malignant pleural mesothelioma (MPM) is the most common type in all malignant mesothelioma. The onset of MPM is associated with exposure to asbestos and it can have an incubation period of up to 40 years.

In vitro and in vivo investigation of the inhibitory effects of Sinoporphyrin sodium-mediated Sonodynamic therapy on human oral squamous cell carcinoma.

Methods: Fluorescence spectra, cytotoxicity assessments, uptake mechanisms, and subcellular distributions of DVDMS within the SCC-154 cell line were detected.

A High-Performance Polyimide Composite Membrane with Flexible Polyphosphazene Derivatives for Vanadium Redox Flow Battery.

A sulfonated polyimide, S-F-abSPI, with alkyl sulfonic acid side chains, and a polyphosphonitrile derivative, poly[4-methoxyphenoxy (4-fluorophenoxy) phosphazene] (PFMPP), were designed and synthesized. Composite modification of the S-F-abSPI membrane was carried out using PFMPP, resulting in the preparation of composite membranes with different composite ratios, which were then subjected to performance testing and characterization. Experimental results revealed a significant enhancement in the proton conductivity of the S-F-abSPI membrane, reaching 0.

Characterization of phage HZY2308 against Acinetobacter baumannii and identification of phage-resistant bacteria.

What Limits the Stability Performance of Polymeric Carbon Nitride Photoanode for Photoelectrochemical Water Splitting?

Although many researches have been reported about the high performance of polymeric carbon nitride (PCN) photoanode, but it is still limited by poor stability.

Enhanced Photocatalytic Hydrogen Evolution of InS by Decorating InO with Rich Oxygen Vacancies.

The hydrogen (H) evolution rates of photocatalysts suffer from weak oxidation and reduction ability and low photogenerated charge carrier separation efficiency. Herein, by combining band-gap structure optimization and vacancy modulation through a one-step hydrothermal method, InO containing oxygen vacancy (O/InO) is simply introduced into InS to promote photocatalytic hydrogen evolution. Specifically, the change in the sulfur source ratio can induce the coexistence of O/InO and InS in a high-temperature hydrothermal process.
