Researchers from the University at Buffalo (UB) have developed a novel 3D printed water-purifying graphene aerogel. Their intent is for the gel to be deployed and scaled for use at large wastewater treatment plants.
To create this gel, the team added “bio-inspired polydopamine”, or PDA, and bovine serum albumin (BSA) to a powder, allowing for the 3d printing of graphene products. The scientists then printed a test sample before freezing and freeze-drying it, creating a G-PDA-BSA aerogel.
