Advanced Science, EarlyView.Magnesium silicide (Mg2Si) is introduced as a narrow‐bandgap, biodegradable semiconductor for transient electronics. RF‐sputtered and annealed Mg2Si thin films show high intrinsic electrical conductivity and low thermal conductivity. The polycrystalline material undergoes hydrolysis in aquatic and composting environments with minimal cytotoxicity ...

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

Advanced Science, EarlyView.The size mismatch between the micropore channel and [Zn(H2O)6]2+ in porous carbon anode during the discharge process was addressed by regulating the hierarchical channel. The inducted stepwise de‐solvation of [Zn(H2O)6]2+ significantly reduced its de‐solvation energy, promoted the EDLC behavior, and strengthened the diffusion kinetic.
