Vacuum impregnation, particularly Vacuum Pressure Impregnation (VPI), is a highly effective process Delba Electrical uses in ...

These devices suffer long-term electrical, thermal, and vibrational stresses during ... by reducing free volume before 72 h. While in the degradation stage, chain-breaking and oxidation of epoxy ...

However, this approach led to significant current degradation due to delamination caused by thermal contraction mismatch between the epoxy composites and the HTS tape. The partial-depth impregnation ...

Perovskite solar cells are highly efficient and low cost in production. However, they still lack stability over the decades under real weather conditions. An international research collaboration has ...

Thermal underwear is known by many names — long johns, base layers, long underwear, skivvies, or even britches (for my Southern friends). No matter what you call them, they are a staple for anyone ...

Unsurprisingly, this is also a common worry among people that are looking to buy their first electric car. But is battery degradation in electric vehicles (EVs) fact or fiction? To find out, each year ...
