High-speed images of a common laser-based metal 3-D printing process, coupled with newly updated computer models, have revealed the mechanisms behind material redistribution, a phenomenon that leads ...
Researchers have determined formulas to guide development of a promising new high-tech material, composed of insulating metal oxides known as alkaline-earth-metal binary oxides, that could lead to ...
Volumetric defect types commonly observed in the additively manufactured parts differ in their morphologies ascribed to their formation mechanisms. Using high-resolution X-ray computed tomography, ...
The heavy use of fossil fuels for driving industrial processes and human activities has resulted in increasingly excessive emissions of anthropogenic CO 2 into our atmosphere, surpassing the 400 ppm ...
(Nanowerk Spotlight) Rechargeable lithium-ion (Li-ion) batteries are the dominant technology not only for portable electronics but it also is becoming the battery of choice for electric-vehicle and ...
The formation of lithium dendrites is still a mystery, but materials engineers study the conditions that enable dendrites and how to stop them. Historically, as in decades ago, rechargeable lithium ...
