Owing to the abundant resources of potassium resources, potassium ion batteries (PIBs) hold great potential in various energy storage devices. However, the poor lifespan of PIBs anodes limit their merchant applications. The exploitation of anode materials with high performance is one of the critical factors to the development of PIBs. Metallic Sn-, Sb-, and Bi-based materials, show promising future thanks to their high theoretical capacities and safe working voltage. However, the rapid capacity decay caused by the large K is still a pivotal challenge. In this review, recent progresses on alloying anodes were summarized. Schemes, such as ultra-small nanoparticles, hetero-element doping, and electrolyte optimization are effective strategies to improve their electrochemical properties. This review provides an outlook on the nanostructures and their synthesis methods for the alloying-type materials, and will stimulate their intensive study for practical application in the near future.

Background: Sedentary behavior (SB) and the absence of physical activity (PA) have become increasingly prevalent in modern societies due to changes in physical and social-environmental conditions, particularly in university students. This cross-sectional study aimed to describe and identify the prevalence and correlates of self-reported and accelerometer-determined SB and PA of German university students.
Methods: A convenience sample of 532 students participated in a questionnaire survey during the lecture period in the summer term 2018.

New evidence has revealed ambient fine particulate matter < 2.5 μm (PM) may have endocrine disrupting effect, such as thyroid hormone disorder, while which PM constituents contributed to the effect was debatable. The study aimed to identify the specific PM constituents regarding to acute endocrine disrupting effect.

Recently, joint replacement surgery is facing significant challenges of patient dissatisfaction and the need for revision procedures. In-situ monitoring of stress stability at the site of artificial joint replacement during postoperative evaluation is important. Mechanoluminescence (ML), a novel "force to light" conversion technology, may be used to monitor such bio-stress within tissues.

Introduction: Irinotecan (CPT-11), a topoisomerase I inhibitor, serves as a prodrug for SN-38, its active metabolite with significantly higher cytotoxic potency. Despite its clinical efficacy, irinotecan's therapeutic potential is limited by low fraction of conversion to SN-38, inefficient tumor targeting, and dose-limiting toxicities such as diarrhea and neutropenia. Nanoparticle-based formulations, such as SNB-101, offer a promising solution by encapsulating irinotecan and SN-38, enhancing solubility, improving drug delivery efficiency, and reducing systemic toxicity through tumor-specific accumulation via the enhanced permeability and retention (EPR) effect.

Background: Strengthening mRNA vaccine development in LMICs is essential for enhancing global pandemic preparedness. This study evaluated the safety and immunogenicity of Comvigen, a bivalent SARS-CoV-2 vaccine, in comparison to the Comirnaty bivalent vaccine (Comirnaty).
Methods: This phase II, randomised, open-label, non-inferiority trial was conducted in Thailand across four centres.
