Unraveling Mechanisms and Engineering Strategies for Superior Photocarrier Dynamics Toward Efficient Photocatalysis

EcoEnergy, Volume 4, Issue 3, June 2026.
Despite its potential, photocatalysis is limited by inefficient charge carrier separation and transport. This article reviews the mechanisms, characterization methods, and strategies for improvement, concluding with future challenges in the field. ABSTRACT Photocatalysis offers a promising solution to environmental and renewable energy issues. However,

Counterfeit Citri Reticulatae Pericarpium Identification: Multi‐Class Detection Using Vis/NIR Spectroscopy and Residual Neural Networks

Food Science &Nutrition, Volume 14, Issue 6, June 2026.
Citri Reticulatae Pericarpium (CRP) samples undergo authentic processing through natural air drying and preservation, whereas counterfeit CRP can be produced through high‐temperature treatment, chemical agents, dyeing, or acid–alkali processing. Vis/NIR spectral analysis combined with WGAN‐GP augmentation and Inception‐ResNet classification captures ...

Ultralow‐Backscattering Induced Mode Splitting in Chipscale Valley Photonic Topological Cavities

Laser &Photonics Reviews, Volume 20, Issue 12, 18 June 2026.
The proposed in‐situ metrology based on mode splitting quantifies the ultralow backscattering of topological valley edge states at a single sharp corner, demonstrating near‐lossless topological transport (0.09 dB/corner) on a silicon chip. This work provides insight into the robustness of the photonic valley system and shows the great potential of ...

Enhancing Charge Transport and Extraction in Ta3N5 Photoanodes Via Ti Doping and TiN Contact Layers

Small, Volume 22, Issue 31, 2 June 2026.
Ta3N5${\rm Ta}_3{\rm N}_{5}$ is a promising photoanode for solar water splitting but suffers from poor charge transport and interfacial losses. We combine Ti compensation doping with ultrathin TiN back‐contact interlayers to suppress bulk recombination, enhance carrier mobility and lifetime, and enable efficient carrier extraction, yielding ...
