Aqueous Supercapacitor with Wide‐Temperature Operability and over 100,000 Cycles Enabled by Water‐in‐Salt Electrolyte

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
This study presents a symmetric supercapacitor with activated carbon electrodes and a “water‐in‐salt” electrolyte (WiSE) based on lithium perchlorate, offering over 100,000 cycles with over 90 % capacity retention. The supercapacitor operates efficiently from −20 to 80 °C, enhancing performance, stability, and all‐season operability.

State‐of‐Art in Studying the Public Health Effects of Heat: A Literature Review

open access: yesGlobal Challenges, EarlyView.
This review aims to consolidate current knowledge about the public health impact of heat. Pathophysiological mechanisms are well‐known, but an ‘environmental epidemiology’ perspective is essential to drive adaptation strategies. Abstract The impact of heat and heatwaves on human health constitutes a significant hazard, disproportionately affecting ...

Viologen phosphoric acid salt modified PEDOT:PSS for high‐performance 3D perovskite photodetectors

open access: yesInfoMat, EarlyView.
A novel viologen derivative, APV, is incorporated into PEDOT:PSS to enhance the performance of 3D perovskite photodetectors. The optimized device achieves an ultra‐low dark current of 5.75 × 10−7 mA cm−2 and a large bandwidth of 1.5 MHz. Integrated into an optical wireless communication system, it achieves a data rate of 12.5 Mbps, demonstrating ...

Illuminating Satellite Cells: Light Sheet Fluorescence Microscopy for 3D Imaging of Murine Skeletal Muscles Damaged by Ex Vivo Forced Eccentric Contraction

open access: yesMicroscopy Research and Technique, EarlyView.
This study presents the light sheet fluorescence microscopy (LSFM) as a tool for 3D‐imaging of whole skeletal muscle to reveal satellite cells (SCs), the muscle stem cells that activate following damage to repair injured tissue. After tissue clearing and whole‐mount staining process aimed to enable optical access and specific cell labeling (1), murine ...

Challenges and opportunities in mitigating sarcoptic mange in wild South American camelids

open access: yesThe Journal of Wildlife Management, EarlyView.
Wild South American camelids—vicuña and guanaco—face threats from sarcoptic mange, a contagious skin disease linked to severe population declines. Despite its impact, major gaps remain in understanding disease dynamics. This review summarizes current knowledge, identifies key data and management gaps, and outlines urgent actions for effective ...
