Beyond Imperfect Match: Silicon/Graphite Hybrid Anodes for High‐Energy–Density Lithium‐Ion Batteries
Silicon/graphite (Si/Gr) hybrid anodes are limited by Si's large volume change and mismatch with Gr. This review offers mechanistic insights into imperfectly matched Si/Gr hybrid anodes, elucidating heterogeneous lithiation behavior and interfacial failure pathways, and thereby informing the design of durable, high‐energy–density lithium‐ion batteries.

Mean velocity, turbulence intensity, and scale in a subsonic turbulent jet impinging normal to a large flat plate [PDF]
To explain the increase in noise when a jet impinges on a large flat plate, mean velocity, turbulence intensity, and scale were measured at nominal nozzle-exit velocities of 61, 138, and 192 meters per second with the plate located 7.1 nozzle-exit ...

This study presents a compact freeform projection optics using dual wedge prisms for waveguide displays. Unlike previous designs that separate illumination and imaging paths, a freeform optical path integrates both. The system achieves a 32º field of view, 37.5 pixels per degree, and a total volume of less than 2 cm3.
