Biomass-derived composite aerogel for arsenic removal from water
Spent coffee grounds present a valuable resource for natural reducing agents and cellulose. This work demonstrates the valorization of spent coffee grounds (CG) to produce composite aerogels for arsenic removal from wastewater. Phenolic compounds extracted from CG were used as a natural reducing agent to produce iron particles in the aerogel. Cellulose (CC) was further …

Shape-Adaptive Bio-based Sponge: An Alternative Material for Safer Bleeding Control
In situations involving wounds or surgical procedures, rapid and effective hemostasis is critical. Even injuries that appear minor and are commonly encountered in daily life such as knife cuts, tooth extractions, or wisdom tooth surgery, can lead to increased risks if bleeding cannot be controlled. These risks include excessive blood loss, infection, and other complications, …
