(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 ...

(Nanowerk News) University of Wisconsin-Madison engineers have found a way to simultaneously mitigate three types of defects in parts produced using a prominent additive manufacturing technique called ...

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 ...

Using X-ray beams and machine learning for detecting structural defects, such as pore formation, can help prevent failure of metal 3D-printed parts. Systematic computer-based material design uses ...

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 ...

Designing the right scan path, and laser intensity along that path, is key to turning out quality metal parts using laser powder-bed fusion. The most popular 3D printing process for making metal parts ...
