Creating synthetic night-time visible-light meteorological satellite images using the GAN method [PDF]
arXiv, 2021 Meteorology satellite visible light images is critical for meteorology support and forecast. However, there is no such kind of data during night time. To overcome this, we propose a method based on deep learning to create synthetic satellite visible light images during night.

Visible Light Triggered Drug Release from TiO2 Nanotube Arrays: A Novel Controllable Antibacterial Platform [PDF]
Angewandte Chemie International Edition, Volume 55, Issue 2, pages
593-597, January 11, 2016, 2016 In this work, we use a double-layered stack of TiO2 nanotubes (TiNTs) to construct a visible-light triggered drug delivery system. Key for visible-light drug release is a hydrophobic cap on the nanotubes containing Au nanoparticles (AuNPs). The AuNPs allow for a photocatalytic scission of the hydrophobic chain under visible light.

True color night vision correlated imaging based on intensity correlation of light [PDF]
arXiv, 2021 Night vision imaging is a technology that converts non-visible object to human eyes into visible image in night and other low light environments. However, the conventional night vision imaging can only directly produce grayscale image. Here, we propose a novel night vision imaging method based on intensity correlation of light. The object's information
