Magnetic Field-Assisted Photocatalysis: Mechanisms, Devices, and Applications.

The magnetic field as a "non-contact" external field can instantaneously affect the separation and migration of photogenerated carriers during the photocatalytic reaction. This facilitates the large-scale industrial application of photocatalysis technology. Consequently, the potential for using external magnetic fields to enhance photocatalysis in environmental pollution control and clean energy production has received significant attention.

Design and Development of Metasurface Materials for Enhancing Photodetector Properties.

Recently, metasurface-based photodetectors (metaphotodetectors) have been developed and applied in various fields. Metasurfaces are artificial materials with unique properties that have emerged over the past decade, and photodetectors are powerful tools used to quantify incident electromagnetic wave information by measuring changes in the conductivity of irradiated materials. Through an efficient microstructural design, metasurfaces can effectively regulate numerous characteristics of electromagnetic waves and have demonstrated unique advantages in various fields, including holographic projection, stealth, biological image enhancement, biological sensing, and energy absorption applications.

Photocatalytic performance of heterojunction S-Tyr-NDI-Tyr/TiO formed by self-assembled naphthalimide derivatives and titanium dioxide.

In this paper, a type of heterojunction photocatalyst S-Tyr-NDI-Tyr/TiO was prepared by self-assembly of tyrosine-substituted naphthamide (NDA) and bonding with titanium dioxide.
