As the first step toward understanding how NADPH levels are regulated in Bacillus subtilis, we sought to obtain mutant strains with enhanced NADPH levels. Our previous study demonstrated that in a strain of B. subtilis expressing bacterial luciferase derived from Photorhabdus luminescens, artificially enhancing NADPH levels enhanced luciferase luminescence in the colonies.

Circularly polarized luminescence (CPL) materials have developed rapidly in recent years due to their wide application prospects in fields like 3D displays and anti-counterfeiting. Utilizing energy transfer processes to transfer chirality has been proven as an efficient way to obtain CPL materials. However, the physics behind energy-transfer induced CPL is still not clear.

Au nanoclusters often demonstrate useful optical properties such as visible/near-infrared photoluminescence in addition to remarkable thermodynamic stability owing to their superatomic behavior. The smallest of the 8e- superatomic Au nanoclusters, Au11, has limited applications due to its lack of luminescence and relatively low stability. In this work, we investigate the introduction of a single Pt dopant to the center of a halide- and triphenylphosphine-ligated Au11 nanocluster, obtaining a cluster with a proposed molecular formula PtAu10(PPh3)7Br3.

High-k metal oxides are gradually replacing the traditional SiO dielectric layer in the new generation of electronic devices. In this paper, we report the production of five-element high entropy metal oxides (HEMOs) dielectric films by solution method and analyzed the role of each metal oxide in the system by characterizing the film properties. On this basis, we found optimal combination of (AlGaTiYZr)O with the best dielectric properties, exhibiting a low leakage current of 1.

Tin-based perovskite has emerged as an excellent luminescent material due to its non-toxicity and narrow bandgap compared to lead-based perovskite. However, its tin ions are easily oxidized by oxygen, which leads to increased vacancy defects and poor crystallinity, presenting a significant challenge in obtaining high-quality perovskite films. In this context, we introduced an approach by synergistically adding SnF and tin powder into the precursor solution to enhance the antioxidation of Sn ions.
