Researchers tune thermal conductivity of materials "on the fly" for more energy-efficient devices
A team led by University of Minnesota Twin Cities scientists and engineers discovered a new method for tuning the thermal conductivity of materials to control heat flow "on the fly." Their tuning range is the highest ever recorded among one-step proc.....»»
River diversions may cause microplastics to remain longer on land and in streams before reaching oceans
Diverting streams and rivers to irrigate crops or provide drinking water may significantly extend the time microplastics spend in river catchments before they flow into our oceans, a new study reveals......»»
Discovery challenges 30-year-old dogma in associative polymers research
A University of Virginia-led study about a class of materials called associative polymers appears to challenge a long-held understanding of how the materials, which have unique self-healing and flow properties, function at the molecular level......»»
Improving fluid simulations with embedded neural networks
