VTT's second independent test shows Donut Lab's solid-state cell delivered 110% capacity at 80°C and survived 100°C discharge, but key claims remain unproven.

As part of its 'I Donut Believe' campaign, Finnish battery developer Donut Lab has published further independent test results for its disputed solid-state ...

Most ultrasonic flaw detection and thickness gaging are carried out at normal temperatures. However, sometimes a hot material requires testing, for example, in process industries. In these instances, ...

Industries as diverse as aerospace, automotive, food, beverage, pharmaceutical, power, oil and gas and many more have a common requirement: that materials used in processes and manufacturing can ...

Because a composite material’s stiffness and strength tend to decrease as temperature and moisture content increase, these deformations and stresses can be significant in many applications. This ...
