Molding the flow of light—whether confined to localized regions or propagating in free space—remains crucial for modern integrated photonics. The advancement of the multi-channel, programmable optical ...

Figure 1. (A, B) Structural design of the topological polycrystal and its frequency supercurvature distribution in the synthetic hybrid space. (C, D) Supercell projected band structure at a specific ...

Tetragonal zirconia polycrystal (TZP) is commonly stabilized with 3% to 5% Yttria and has the finest grain size. Since they are almost entirely tetragonal, these zirconia grades have the maximum ...

Naturally occurring and synthetic materials are often 'polycrystalline', comprised of single-crystalline grains bonded to one another across interfaces known as grain boundaries. Grain boundaries are ...
