Summary: Thin 2D materials at atomic scale have transformed various fields, but their applications are hindered by the lack of scalable production methods. A new strategy using amphiphilic graphene quantum dots to exfoliate 2D materials and form vdWHs shows enhanced electrocatalytic performance for hydrogen evolution reaction. This study not only provides a new method for preparing ultrathin 2D microsheets, but also reveals the potential of GQD-based vdWHs as non-precious electrocatalysts.

Summary: In this study, a series of 0D boron carbon nitride quantum dots (BCNQDs) modified 2D Bi4O5I2 (0D/2D Bi4O5I2/BCNQDs) composites were synthesized and applied to photodegradation of tetracyclines (TCs), including tetracycline (TC) and oxytetracycline (OTC). The optimal composite Bi4O5I2/BCNQDs (1 mL BCNQDs) exhibited the highest photocatalytic performance, with degradation rate constants for TC and OTC being 4.95 and 2.17 times higher than that of Bi4O5I2, respectively. This can be attributed to the narrow bandgap property of Bi4O5I2 as an electron acceptor, and the oxygen-containing functional group with negative charge on BCNQDs promoting the formation of photoexcited holes for effective carrier separation.

Summary: The study investigated a 2D ZnV2O6 heterojunction modified by reduced graphene oxide and g-C3N4 for enhanced photocatalytic CO2 reduction under visible light. The composite catalyst showed excellent photoactivity, with a maximum CO yield rate 7.4 and 1.7 times higher than using g-C3N4 and ZnV2O6 alone, respectively. The improvements were attributed to the synergistic effect of the 2D layer heterojunction and enhanced charge separation by the RGO mediator under visible light.

Summary: Band alignment engineering is utilized to design van der Waals heterojunctions (vdWHs) based on two-dimensional transition metal dichalcogenides (TMDs)/alpha-In2Se3, where TMDs are used as the channel and alpha-In2Se3 is assembled as an asymmetric gate. The band offset in the homogeneous TMDs channel can be tuned by coupling the effect of the semiconducting nature and asymmetric ferroelectric gate of alpha-In2Se3, which induces simultaneous rectifying and memory functions.

Summary: Nonhealing diabetic wounds can be effectively healed by training macrophages to mimic the reparative functions of tumor-associated macrophages (TAMs), which produce immunosuppressive and proliferative factors. These TAM-educated macrophages (TAMEMs) outperform other macrophage phenotypes in reducing inflammation, promoting angiogenesis, and activating fibroblasts. A nine-factor cocktail has also been developed to train human primary monocytes into TAMEMs, enabling the preparation of safer and autologous cells. This study demonstrates the potential of recapitulating TAMs' reparative activities in non-tumor cells for regenerative medicine.

Summary: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.
