Spacer-engineering construction of continuous proton transport networks for cardo poly(biphenyl indole) high-temperature proton exchange membranes Proton-exchange membranes are considered the core of high-temperature proton-exchange membrane fuel cells (HT-PEMFCs), which determine the output power of the cells. However, current HT-PEMs, which are mainly doped with phosphoric acid (PA), face challenges such as low conductivity and loss of PA during cell operation.

We propose a single-layer graphene electro-absorption modulator (EAM) with an angled waveguide sidewall. By utilizing the hybridization of the TM0 mode and the TE1 mode in the waveguide, the light–graphene interaction is enhanced. A modulation depth of 0.124 dB/µm and a figure of merit up to 25 are obtained at 1550 nm.

Abstract Electrides are a special family of materials with exotic physical properties and various crystal structures in different dimensions. Among them, alkaline-earth metal nitrides (AE2N) have attracted enormous attention, since the synthesis of Ca2N as a two-dimensional (2D) electride. However, apart from Ca2N, the physicochemical properties of other AE2N are not well understood, and in some cases, their crystal structures remain unknown.
