Intentional cracks in the sidewalk are a perfect example of how engineers deal with thermal expansion. By filling these gaps with a flexible material, the engineers create what's known as a ...

Superinsulating aerogel resists mechanical and thermal shocks. Creating composites with near-zero thermal expansion. NTE materials mixed with a PTE material in composites that have near-zero thermal ...

Technical Ceramics and Thermal Expansion Coefficients. In comparison to metals, technical ceramics characteristically exhibit a lower CTE because of their unique structural makeup and low thermal ...

Their closely matched experimental observations of the material’s thermal expansion, providing them with key insights into why the material has a negative thermal expansion in just one direction. “Our ...
