It's a well-known characteristic of metals that repeated bending in the same place can cause the material to weaken and eventually break; this phenomenon, known as metal fatigue, can cause serious ...

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 ...

Lithium metal is known to possess a very high theoretical capacity of 3,842 mAh g −1 in lithium batteries. However, the use of metallic lithium leads to extensive dendritic growth that poses serious ...

(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 ...

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 ...

Layered double hydroxides (LDHs) are emerging as promising electrocatalysts for the oxygen evolution reaction (OER), a key ...

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 ...

OAKLAND — Preliminary tests of the BART rail that broke May 5, jamming the morning commute throughout the system, revealed an anomaly that could be a defect in the metal, transit district directors ...
