UrduResearchers who previously demonstrated a cooling fabric coating now report on additional tests of a treated polyester fabric in ACS Applied Materials & Interfaces. Fabric treated with the team’s chalk-based coating kept the air underneath up to 6 degrees Fahrenheit cooler in warmer urban environments.

Sandia tests heat shields for space
For decades, Sandia National Laboratories’ National Solar Thermal Test Facility has harnessed the power of the sun to expose aerospace materials to intense heat, replicating the harsh conditions of faster-than-sound flight and atmospheric reentry to ensure the materials’ ability to protect the rest of the vehicle. The most recent of these tests is in support of two exciting NASA missions.
Hitting this stretchy, electronic material makes it tougher
Dropping wearable electronics, or hitting them really hard, usually breaks the devices. Now, researchers report on a flexible and electrically conductive material with “adaptive durability,” getting stronger when it is hit. They will present their results at ACS Spring 2024.
This loofah-inspired, sun-driven gel could purify all the water you’ll need in a day
Devices currently in development that clean up dirty water using sunlight can only produce a few gallons of water each day. But now, researchers in ACS Central Science report how a sunlight-powered porous hydrogel could potentially purify enough water to meet daily needs — even when it’s cloudy.
Designing better water filters with AI
Researchers in ACS Central Science report that artificial intelligence (AI) could speed up the development of promising water filtration materials. In a proof-of-concept study, they simulated different patterns of water-attracting and water-repelling groups and found optimal arrangements.
Haim Waisman: Then and Now / 2012 Early Career Award Winner
Haim Waisman develops computational models of the mechanics of materials. He focuses on fracture phenomena, such as ice breaking due to climate warming, infrastructure aging and deteriorating, energy extraction from rocks, and fractures in biomaterials such as bones.
