Polarization‐Dependent 3D Holography Generated by Inverse Design Nanoprinting Metasurface

open access: yesAdvanced Science, EarlyView.
A novel polarization‐dependent 3D holography is proposed by introducing polarization as an additional freedom, enabling enhanced depth selectivity and greater control over holographic reconstruction. The efforts perfectly combine the polarization and 3D holography display into ADAM gradient descent algorithm, the application of nanoprinting further ...

Surface Graphitized Mesoporous Carbon Surpasses the Conductivity–Porosity Trade‐Off

open access: yesAdvanced Science, EarlyView.
Electrochemical cathodic polarization in molten CaCl2‐NaCl converts mesoporous carbon (MC) into surface‐graphitized mesoporous graphite, simultaneously increasing surface area (397–867 m2/g) and electrical conductivity (26–450 S/cm) without mass loss.
