A facile strategy for the preparation of multifunctional Janus membranes was proposed, and excellent controllability of the membrane was demonstrated.

A new way to fabricate asymmetric, flexible, and ultrathin liquid metal Janus films with electrical, optical, and thermal anisotropies is demonstrated.

Nature-inspired ionic conductors based on supramolecular nanofibril are developed for flexible and stretchable strain/pressure sensors.

This review systematically summarizes the limitations of solid electrolytes including inorganic solid electrolytes, solid polymer electrolytes, and composite solid electrolytes.

The concept of electronic dimensionality,i.e., the connectivity of the atomic orbitals that comprise the lower conduction band and upper valence band, is introduced to better account for the device performance of the perovskite-based solar cells.

Mechanochemistry became a powerful and popular method for the preparation of various porous materials.

Quasi-solid-state micro-supercapacitors with cellular graphene film as the active material and polyvinyl alcohol/H₃PO₄as the gel electrolyte have been fabricated. The 3D porous graphene films not only serve as high performance supercapacitor electrodes, but also provide an abundant ion reservoir for the gel electrolyte.

Electronic levels and energies of a solid, such as Fermi level, vacuum level, work function, ionization energy or electron affinity, are of paramount importance for the control of device behavior, charge carrier injection and transport.
