Why Does Water Expand When it Cools? A New Explanation
(PhysOrg.com) -- Most of us, when we take our first science classes, learn that when things cool down, they shrink. (When they heat up, we learn, they usually expand.) However, water seems to be the exception ...
For the first time, researchers observe graphene sheets becoming buckyballs (w/ Video)
(PhysOrg.com) -- Peering through a transmission electron microscope (TEM), researchers from Germany, Spain, and the UK have observed graphene sheets transforming into spherical fullerenes, better known as ...
New analysis of the structure of spider silks explains paradox of super-strength
Spiders and silkworms are masters of materials science, but scientists are finally catching up. Silks are among the toughest materials known, stronger and less brittle, pound for pound, than steel. Now scientists ...
