Deep-Ultraviolet Beam Homogenizers: Phase-Modulated Metalens vs. Space-Modulated Chromium Thin-Film
Deep-ultraviolet (DUV, 193 nm) tools for lithography and precision micromachining are often limited by beam-profile nonuniformity, which degrades critical-dimension control, line-edge roughness, and process windows.

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...
