Metals consist of stacked layers of tightly packed, interacting atoms arranged in geometric patterns. Each of these atoms contains a small number of loosely held electrons in its outer shell. When ...
Inspired by the way diving bell spiders and fire ants use their water-repelling legs and bodies to trap air in order to float on water, researchers from the University of Rochester have found a way to ...
Chinese scientists have successfully completed country's first space-based laser wire-fed metal additive manufacturing experiment under microgravity conditions, conducting the work during a suborbital ...
Close up of a water drop on a rose petal. Rose petals exhibit a property called superhydrophobicity, which is of interest to material scientists. Now, researchers at Iowa State University have managed ...
It's long been assumed that when a metal structure like a bridge or an engine develops a crack, it will only get worse over time. But that might not be the case, based on what researchers have just ...
A metal is comprised of many individual crystals, or grains. These crystals are held together by electrons in the same way that electrons hold the atoms within each crystal together. For more on this ...
