In Situ Formation of WC/WC Heterostructures on N-Doped Carbon for Deep Oxidative Desulfurization of Fuel Oil.

A novel tungsten-based heterojunction nanocomposite material was developed for the efficient oxidative desulfurization (ODS) of fuel oil, enabling the production of low-sulfur fuel and a reduction in harmful SO emissions. In this material, the WC/WC heterojunction was uniformly immobilized on a porous nitrogen-doped carbon (NC) matrix structure through facile in situ pyrolysis of polyaniline-phosphotungstic acid (PANI/PTA) precursors. The resultant WC/WC@NC catalyst demonstrated remarkable desulfurization performance, achieving 100% removal of 4000 ppm dibenzothiophene (DBT) in just 15 min at 60 °C in the presence of 0.

Defective silicotungstic acid-loaded magnetic floral N-doped carbon microspheres for ultra-fast oxidative desulfurization of high sulfur liquid fuels.

Highly active Keggin-type silicotungstic acid (SiW) with oxygen vacancy (O) defects was encapsulated into the magnetic floral N-doped carbon microspheres (γ-FeO@NC-300) through the facile one-step air pyrolysis of the precursor comprising core-shell FeO@polydopamine (FeO@PDA) and SiW to prepare γ-FeO@NC@SiW-300. The fabricated catalysts were systematically characterized and subsequently employed for the oxidation desulfurization (ODS) of the model fuel. The magnetic floral γ-FeO@NC@SiW-300 catalyst exhibited nearly perfect catalytic activity, which under mild conditions could remove 100% amount of 4000 ppm DBT in model fuel within 20 min (0.

Efficient heterogeneous Fenton-like degradation of methylene blue using green synthesized yeast supported iron nanoparticles.

To reduce the consumption of oxidant and catalyst in Fenton-like reaction and to realize the reuse of catalyst, yeast supported iron nanoparticles (nZVI@SC) was synthesized by tobacco leaf extract and applied in the heterogeneous Fenton-like degradation of aqueous methylene blue (MB) at ambient conditions. The performance of the composite was exploited in terms of catalytic activity and factors influencing MB degradation. The surface changes of nZVI@SC before and after reaction were characterized by XPS, SEM, FT-IR and XRD.

Regulating Macrophages through Immunomodulatory Biomaterials Is a Promising Strategy for Promoting Tendon-Bone Healing.

The tendon-to-bone interface is a special structure connecting the tendon and bone and is crucial for mechanical load transfer between dissimilar tissues. After an injury, fibrous scar tissues replace the native tendon-to-bone interface, creating a weak spot that needs to endure extra loading, significantly decreasing the mechanical properties of the motor system. Macrophages play a critical role in tendon-bone healing and can be divided into various phenotypes, according to their inducing stimuli and function.

Advances in sports food: Sports nutrition, food manufacture, opportunities and challenges.

In recent years, the increase in public awareness of sports has greatly promoted the development of the sports food industry. Sports food provides nutrition to meet the metabolic and energy needs of sports people. The nutritional components of sports food can be divided into basic nutrients and functional factors.

Recent Progress on Protein-Polyphenol Complexes: Effect on Stability and Nutrients Delivery of Oil-in-Water Emulsion System.

Oil-in-water emulsions are widely encountered in the food and health product industries. However, the unsaturated fatty acids in emulsions are easily affected by light, oxygen, and heat, which leads to oxidation, bringing forward difficulties in controlling emulsion quality during transportation, storage, and retail. Proteins are commonly used as emulsifiers that can enhance the shelf, thermal and oxidation stability of emulsions.

Phthalocyanine-sensitized evolution of hydrogen and degradation of organic pollutants using polyoxometalate photocatalysts.

In this study, 2 (3), 9 (10), 16 (17), 23 (24)-tetrakis-(8-quinoline-oxy) phthalocyanine zinc(II) (ZnQPc) was prepared and then quaternized to obtain water soluble zinc phthalocyanine (ZnQPc). Then, ZnQPc was used as a photosensitizer for a series of POM catalysts, including Dawson type K[α-PWO]·14HO (PW) and K[α-PWO]·20HO (PW) and Keggine type HPWO·xHO (PW). The Keggin type PW showed higher efficiency with 18.
