Stable Fluorescence of Eu Complex Nanostructures Beneath a Protein Skin for Potential Biometric Recognition.

We designed and realized highly fluorescent nanostructures composed of Eu complexes under a protein coating. The nanostructured material, confirmed by photo-induced force microscopy (PiFM), includes a bottom fluorescent layer and an upper protein layer. The bottom fluorescent layer includes Eu that is coordinated by 1,10-phenanthroline (Phen) and oleic acid (O).

The transcription factor AtGLK1 acts upstream of MYBL2 to genetically regulate sucrose-induced anthocyanin biosynthesis in Arabidopsis.

Background: The regulation of anthocyanin biosynthesis by various factors including sugars, light and abiotic stresses is mediated by numerous regulatory factors acting at the transcriptional level. Here experimental evidence was provided in order to demonstrate that the nuclear GARP transcription factor AtGLK1 plays an important role in regulating sucrose-induced anthocyanin biosynthesis in Arabidopsis.

Results: The results obtained using real-time quantitative PCR and GUS staining assays revealed that AtGLK1 was mainly expressed in the green tissues of Arabidopsis seedlings and could be induced by sucrose.

2D/2D Heterojunction of R-scheme TiC MXene/MoS Nanosheets for Enhanced Photocatalytic Performance.

Combination of two-dimensional (2D) materials and semiconductors is considered to be an effective way for fabricating photocatalysts for solving the environmental pollution and energy crisis. In this work, novel 2D/2D heterojunction of R-scheme TiC MXene/MoS nanosheets is successfully synthesized by hydrothermal reaction. The photocatalytic activity of the TiC MXene/MoS composites is evaluated by photocatalytic degradation and hydrogen evolution reaction.

Construction of BPQDs/TiC@TiO Composites with Favorable Charge Transfer Channels for Enhanced Photocatalytic Activity under Visible Light Irradiation.

Design and construction of double heterojunction is favorable to improve the separation and migration efficiency of photogenerated carriers, thus preferably solve the problems of environmental pollution and energy crisis. Herein, TiO nanoparticles (NPs) are in-situ grown on highly conductive TiC nanosheets via low-temperature hydrothermal strategy, and then black phosphorus quantum dots (BPQDs) are introduced on the surface of TiO NPs. Under hydrothermal temperature 120 °C, the BPQDs/TiC@TiO photocatalyst exhibits remarkable enhanced photocatalytic degradation of methyl orange (MO) and hydrogen evolution reaction (HER) compared with BPQDs/TiC and TiC@TiO composites.
