Electrochemical deposition offers distinct advantages due to its capability to deposit materials with nanostructures in ambient conditions. This review aims to underscore the principles of electrochemical deposition and its recent applications in enhancing electrodes for solid oxide fuel cells, thus promoting its practical utility in energy conversion devices.

Photocatalytic overall water splitting technology harnesses solar energy to produce hydrogen and oxygen without pollution, presenting a promising solution to contemporary environmental and energy challenges. However, constructing a photocatalyst simultaneously possessing a S-scheme charge transfer path and a tight heterojunction interface is significant challenge. In this work, we construct a low-interfacial barrier Ce-S bond-enhanced Mo-doped ZIS/oxygen-deficient CeO₂ S-scheme heterojunction photocatalyst using a doping-defect coupling strategy, achieving H₂ and O₂ evolution rates with a value of 512.7 and 256.3 μmol g⁻¹ h⁻¹, respectively, along with a STH efficiency of 0.14%.

An S-scheme heterojunction based on CdS nanorods and conjugated polymer 2-hexyl-carbazole-benzothiadiazole was constructed. The obtained composite exhibits high photocatalytic hydrogen production performance, which is attributed to the spatial separation of the photoinduced charges in the S-scheme heterojunction. The Cd–S bonds at the interface promote the separation and transfer of charge carriers.

Efficient Cherenkov radiation over a wide range of momenta is highly demanded for many applications but still remains a challenging task. Here, we demonstrated that twisted hyperbolic Van der Waals crystals enable enhancement of Cherenkov radiation in a broad range of wave vectors. This finding is promising for realizing bright and tunable free-electron light sources that operate in the terahertz and mid-infrared frequency ranges.

A model of a metal halide perovskite (MHP)-based electrically pumped vertical-cavity surface-emitting laser (EPVCSEL) has been developed, presenting a 3D thermal distribution of the device, the normalized light intensity profile, and the as-modeled EPVCSEL characteristics.

The ε phase Ga₂O₃ thin film was deposited on 2-inch commercial c-sapphire substrate using a MOCVD technique. Based on the ε-Ga₂O₃ metal-semiconductor-metal structure photodetector, classical biological synaptic behaviors such as excitatory postsynaptic current, short term memory, long term memory, pair pulse facilitation, and “learning-forgetting-relearning” are probed.
