Vapor deposition assisted in-situ construction of graphitic carbon nitride homojunction capable of enhanced visible-light-driven hydrogen generation.

Graphitic carbon nitride (g-C3N4) has garnered considerable attention in the field of photocatalysis due to its suitable bandgap (~2.7 eV), abundant elemental composition, high chemical stability, and environmentally friendly synthesis process. In this study, a novel g-C3N4 homojunction material with controllable morphology was successfully fabricated via a simple and efficient vapor deposition method.

Graphitic Carbon Nitride for Photocatalytic Hydrogen Production from Water Splitting: Nano-Morphological Control and Electronic Band Tailoring.

Semiconductor polymeric graphitic carbon nitride (g-CN) photocatalysts have garnered significant and rapidly increasing interest in the realm of visible light-driven hydrogen evolution reactions. This interest stems from their straightforward synthesis, ease of functionalization, appealing electronic band structure, high physicochemical and thermal stability, and robust photocatalytic activity. This review starts with the basic principle of photocatalysis and the development history, synthetic strategy, and structural properties of g-CN materials, followed by the rational design and engineering of g-CN from the perspectives of nano-morphological control and electronic band tailoring.

High sensitivity and selectivity of h-BN/WO n-n heterojunction to triethylamine at low-temperature.

Due to the unique properties of heterojunction interfaces, heterojunction materials have broad application prospects in gas sensors. In this work, a facile and economical two-step synthesis method was employed to fabricate h-BN/WO heterojunctions, exhibiting excellent performance in triethylamine (TEA) detection. The results indicate that compared to pure WO sensors, h-BN/WO sensors exhibit superior TEA sensing capabilities, with an excellent response of 281.

Performance Improvement and Application of Degradable Poly-l-lactide and Yttrium-Doped Zinc Oxide Hybrid Films for Energy Harvesting.

Piezoelectric nanogenerators (PENGs) are booming for energy collection and wearable energy supply as one of the next generations of green energy-harvesting devices. Balancing the output, safety, degradation, and cost is the key to solving the bottleneck of PENG application. In this regard, yttrium (Y)-doped zinc oxide (ZnO) (Y-ZnO) was synthesized and embedded into polylactide (PLLA) for developing degradable piezoelectric composite films with an enhanced energy-harvesting performance.

Oxygen vacancies induced by lanthanum-doped indium oxide nanofibers for promoted temperature-dependent triethylamine and formaldehyde sensing.

A novel TEA and HCHO dual-function temperature-dependent sensing material (3La-InO) with ultra-high sensitivity was developed via a facile electrospinning process. Though rare earth doped in InO-based sensors have been widely reported, the low sensitivity, poor selectivity and high operating temperature remain restrict their application. Herein, the InO nanofibers with different contents of La ions are firstly obtained by a facile electrospinning process.

Bifunctionalization of styrene through ring-opening-recombination strategy of phenylpropathiazole salt.

By opening the ring of a benzothiazole salt, we provide a sulfur source for the bifunctional reaction of styrene. The ring-opening-recombination reaction of the benzothiazole salt simultaneously constructs new C-S, C-O, and CO bonds after C-S bond breaking. The reaction proceeds in green solvents, requires no transition metal catalyst, and is compatible with many functional groups.

MicroRNA-16-5p exacerbates sepsis by upregulating aerobic glycolysis via SIRT3-SDHA axis.

Sepsis is a life-threatening condition, and treatment for sepsis in clinic is often not available, partially due to insufficient understanding of the pathogenesis of sepsis. Extensive study to elucidate the pathogenesis is required to improve the clinical management and outcome of sepsis. In this study, we investigated the pathogenesis of sepsis using peripheral blood mononuclear cells (PBMCs) from septic patients and studied the underlying mechanism of miR-16-5p on aerobic glycolysis in lipopolysaccharide (LPS)-treated THP1 and Raw264.
