Fibrous MoS/BiS/BiFeO ternary heterojunction boosts piezoelectric photocatalytic performance.

Photocatalytic removal of antibiotic such as ciprofloxacin from polluted water is of great value for eco-environment protection. To further enhance the piezoelectric effect in photocatalysis, we designed and synthesized a ternary heterojunction piezoelectric photocatalyst through uniformly loading MoS nanosheets onto BiFeO (BFO) nanofibers, namely MoS/BiS/BFO. Piezoresponse force microscopy and Kelvin probe force microscopy demonstrated its enhanced piezoelectric properties, showing a maximum amplitude displacement of 395.

Contribution of soil microbial necromass carbon to soil organic carbon in grassland under precipitation change and its influencing factors in loess hilly region, Northwest China.

To investigate the contribution of microbial necromass carbon (MNC) to soil organic carbon (SOC) and its influencing factors under precipitation changes in grassland, we conducted a precipitation experiment with seven different precipitation levels in the restoration area in the loess hilly region. We analyzed the contents and characteristics of fungal necromass carbon (FNC), bacterial necromass carbon (BNC), and MNC in different fractions of SOC under different treatments, including natural precipitation (CK), and increased and decreased 20%, 40%, 60% of natural precipitation (I, I, I, D, D, D) . The results showed that 1) MNC content in mineral organic carbon (MAOC) ranged from 1.

Copper-based electro-catalytic nitrate reduction to ammonia from water: Mechanism, preparation, and research directions.

Global water bodies are increasingly imperiled by nitrate pollution, primarily originating from industrial waste, agricultural runoffs, and urban sewage. This escalating environmental crisis challenges traditional water treatment paradigms and necessitates innovative solutions. Electro-catalysis, especially utilizing copper-based catalysts, known for their efficiency, cost-effectiveness, and eco-friendliness, offer a promising avenue for the electro-catalytic reduction of nitrate to ammonia.

Bromodomain and extra-terminal inhibitors emerge as potential therapeutic avenues for gastrointestinal cancers.

Gastrointestinal (GI) cancers, including colorectal cancer, pancreatic cancer, liver cancer and gastric cancer, are severe social burdens due to high incidence and mortality rates. Bromodomain and extra-terminal (BET) proteins are epigenetic readers consisting of four conserved members (BRD2, BRD3, BRD4 and BRDT). BET family perform pivotal roles in tumorigenesis through transcriptional regulation, thereby emerging as potential therapeutic targets.

A Dual-Functional Fibrous Skeleton Implanted with Single-Atomic Co-N Dispersions for Longevous Li-S Full Batteries.

Although lithium-sulfur (Li-S) batteries have long been touted as next-generation energy storage devices, the rampant dendrite growth at the anode side and sluggish redox kinetics at the cathode side drastically impede their practical application. Herein, a dual-functional fibrous skeleton implanted with single-atom Co-N dispersion is devised as an advanced modificator to realize concurrent regulation of both electrodes. The rational integration of single-atomic Co-N sites could convert the fibrous carbon skeleton from lithiophobic to lithiophilic, helping assuage the dendritic formation for the Li anode.

A Novel Bi₂MoO₆/ZIF-8 Composite for Enhanced Visible Light Photocatalytic Activity.

A series of novel Bi₂MoO₆/zeolitic imidazolate framework-8 (ZIF-8) photocatalysts have been successfully fabricated through a facile self-assembly process. X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-vis spectrophotometry, and X-ray photoelectron spectroscopy (XPS) characterized pure Bi₂MoO₆, pure ZIF-8, and a series of Bi₂MoO₆/ZIF-8 composites. The result indicated that, when compared with pure Bi₂MoO₆, the composite of Bi₂MoO₆/ZIF-8 exhibited excellent photocatalytic performance for the degradation of methylene blue (MB) under visible light.
