Personal Protective Equipment
The frontline healthcare workers donning personal protective equipment for a prolonged time often face occupational heat strain. In article number 2107636, Xueping Zhang, Swee Ching Tan, and co‐workers address this issue by developing a super‐hygroscopic composite film that absorbs water vapor within the protective suit and enhances sweat evaporation, to create a cooling...
Donning of personal protective equipment (PPE) in the healthcare sector has been intensified by the on‐going COVID‐19 pandemic around the globe. While extensive PPE provides protection, it typically limits moisture permeability and severely hinders the sweat evaporation process, resulting in greater heat stress on the personnel. Herein, a zinc‐poly(vinyl alcohol) (Zn‐PVA) composite film is fabricated...
High temperature brings adverse impacts on the energy efficiency, and even destroys a semiconductor device. Here, a novel and cost‐effective strategy is proposed to boost the energy efficiency of semiconductor devices by using the self‐adaptive evaporative cooling of a lithium‐ and bromine‐enriched polyacrylamide hydrogel. Water inside the hydrogel can quickly evaporate to dissipate the waste heat...
