Abstract: The invention relates to a method and application of a multifunctional interface layer modified composite zinc cathode based on zinc blende in zinc metal batteries. Zinc blende powder is produced by crushing and ball milling, then mixed with a solvent and wet screened. The fine zinc blende is dried and mixed with a surfactant to obtain grafted fine powder.

After drying, the modified composite zinc metal cathode is applied to aqueous zinc metal batteries. This method stabilizes the zinc cathode, isolates electrolyte corrosion, inhibits zinc dendrite growth, and addresses issues of dendrite formation, hydrogen evolution, and corrosion, thereby extending the battery's service life.

Abstract: Quantitative phase imaging (QPI) is a label-free computational imaging technique that provides optical path length information of objects. Here, a diffractive QPI network architecture is disclosed that can synthesize the quantitative phase image of an object by converting the input phase information of a scene or object(s) into intensity variations at the output plane. A diffractive QPI network is a specialized all-optical device designed to perform a quantitative phase-to-intensity transformation through passive diffractive/reflective surfaces that are spatially engineered using deep learning and image data. Forming a compact, all-optical network that axially extends only ˜200-300?
