Metasurfaces and Metadevices for Topological Electromagnetic Waves
Optical topologies refer to diverse topological localized structures made by diverse parameters of light fields, such as vortices, skyrmions, and hopfions. This article navigates a direction of metasurface‐based integrated devices for generation, manipulation and detection of novel topologies of light, which would be a rapidly growing interdisciplinary

Interconversion of Optical to Terahertz Pulses in Nonlinear Beta Barium Borate Crystal
ABSTRACT Low‐temperature β‐phase barium borate (β‐BBO) is an important nonlinear crystal, widely utilized for optical second‐harmonic (SH) generation. Recent re‐measurements of refractive indices in the terahertz (THz) range reveal that β‐BBO is a positive uniaxial crystal.

Metalens‐Enabled Twisted Chromatic Dispersion
We successfully demonstrate visible broadband twisted dispersion metalenses. As a proof of concept, we realized two distinct devices: the conical helical and the spring‐like dispersion‐controlled metalenses. These results rigorously validate the universality of our approach in customizing arbitrary continuous 3D dispersion trajectories, thereby ...

Pressure‐Induced Degradation Effects in Large‐Format Lithium‐Ion Pouch Cells
This study explores how external pressure alters electrochemical aging and thermal behavior in large‐format lithium‐ion pouch cells. Synchrotron X‐ray radiography reveals pressure‐induced inhomogeneous lithiation and structural changes. Moderate pressure improves lifetime and thermal management, demonstrating how mechanical constraints critically ...
