Hypergap materials reveal a second transparent region above the bandgap, overturning assumptions about optical limits and enabling low-loss light control, wavelength conversion, and new photonic ...

In general, when you measure material properties such as optical permittivity, your measurement doesn’t depend on the direction in which you make it. However, recent research has shown that this is ...

The bottom part of the image schematically shows the atomic-level alloying of the HEA, as confirmed by X-ray diffraction (XRD) analysis. A recent study published in Engineering has delved into the ...

(Nanowerk Spotlight) Ever since the first observations of light scattering by particles in the 19th century, achieving ideal optical transparency has posed an enduring grand challenge. Natural solid ...
