NuScale Power has received SMR design approval from the US NRC for its uprated 250MWt (77MWe) NuScale power modules.

Treating structural disorder as a tunable parameter rather than a defect, the researchers revealed a correlation between OR activity and NTE coefficients. "By tuning reversible OR activity, the ...

“It is a material with an extremely low coefficient of thermal expansion over an unprecedentedly wide temperature range,” says Yili Cao. This remarkable temperature behavior has to do with the fact ...

This more complex composition gives it an unprecedented ability to resist thermal expansion. “It is a material with an extremely low coefficient of thermal expansion over an unprecedentedly wide ...

However, a large mismatch of coefficient of thermal expansion (CTE) between silicon (Si) and PSPI will cause serious warpage issue. Furthermore, polyimide deformation may occur under external heat and ...

It has a higher coefficient of volume expansion (b) It has a smaller coefficient of volume expansion ...

In devices made from many different materials, any mismatch in how these materials behave when heated – their positive or negative coefficients of thermal expansion (CTEs) – can have important and ...
