Composite photocatalysts based on metal nanoparticles and functional polymers attract much attention compared to inorganic photocatalysts. In this study, a reusable magnetite/anion exchanger (FeO/PPE-2) functional material is synthesized by a hydrothermal method, and its photocatalytic activity is evaluated for the photocatalytic degradation of Rhodamine B (RhB). The results from materials characterization confirm a well-defined morphology of magnetic FeO/PPE-2 functional material and the formation of FeO nanocrystals with different shapes and sizes on the surface of anion exchange material (PPE-2).

Constructing heterojunctions between phase interfaces represents a crucial strategy for achieving excellent photocatalytic performance, but the absence of sufficient interface driving force and limited charge transfer pathway leads to unsatisfactory charge separation processes. Herein, a doping-engineering strategy is introduced to construct a In─N bond-bridged InS nanocluster modified S doped carbon nitride (CN) nanosheets Z-Scheme van der Waals (VDW) heterojunctions (InS/CNS) photocatalyst, and the preparation process just by one-step pyrolysis using the pre-coordination confinement method. Specifically, S atoms doping enhances the bond strength of In─N and forms high-quality interfacial In─N linkage which serves as the atomic-level interfacial "highway" for improving the interfacial electrons migration, decreasing the charge recombination probability.

Department of Cardiac Rehabilitation, Zhejiang Hospital, Hangzhou, Zhejiang Province, 310007, China.
Objective: the study aimed to analyze the therapeutic effects of neuromuscular electrical stimulation (NMES) combined with respiratory muscle training (RMT) on patients with moderate-to-severe chronic obstructive pulmonary disease (COPD).
Methods: 135 patients with moderate/severe chronic obstructive pulmonary disease were selected as the research object and randomly selected. 72 cases were divided into rehabilitation group and 63 cases in control group.
Wireless system for recording evoked potentials.

Department of Integrative Neuroscience, Graduate School of Medicine and Pharmaceutical Sciences, University of Toyama, Toyama, Japan. Electronic address:
Experiments measuring evoked potentials require flexible and rapid adjustment of stimulation and recording parameters. In this study, we have developed a recording system and an associated Android application that allow making such adjustments wirelessly. The system consists of 3 units: for stimulation, recording and control.

Greenhouse gas (GHG) emissions are creating unprecedented climate-driven extreme weather, with levels of heat and humidity surpassing human physiological tolerance for heat stress. These conditions create a risk of mass casualties, with some populations particularly vulnerable due to physiological, behavioural and socioeconomic conditions (eg, lack of adequate shelter, limited healthcare infrastructure, sparse air conditioning access and electrical grid vulnerabilities). Children, especially young children, are uniquely vulnerable to extreme heat-related morbidity and mortality due to factors including low body mass, high metabolism, suboptimal thermoregulatory mechanisms and behavioural vulnerabilities.
