A research team of Professor Yan Chen from the Tianjin University presents a reconfigurable hierarchical metamaterial, establishes a linear relationship between its stiffness and the number of active ...

Engineers used a process in which a laser instantly flashes metal powder into a fused solid. Using a common titanium alloy, engineers manufactured latticelike structures composed of hollow struts—each ...

(Nanowerk News) Metamaterials are artificially made materials that have certain patterns that change how light and matter interact. As a result, they have properties not found in nature. Researchers ...

(Nanowerk Spotlight) Radar technology has reached a point where it can detect the faintest electromagnetic signals, challenging even the most advanced stealth technologies. The evolution of radar ...

Although it is made of two thermally expanding materials, star-shaped unit cells of the metamaterial have a mechanical design that promotes negative thermal expansion (NTE) when heat is applied. The ...
