2D-2D ZnO/N doped g-CN composite photocatalyst for antibiotics degradation under visible light.

ZnO and g-CN provide excellent photocatalytic properties for degradation of antibiotics in pharmaceutical wastewater. In this work, 2D-2D ZnO/N doped g-CN (NCN) composite photocatalysts were prepared for degradation of tetracycline (TC), ciprofloxacin (CIP) and ofloxacin (OFLX). The addition of ZnO resulted in higher separation efficiency and lower recombination rate of photogenerated charge under visible light.

Effects of potassium additives on the combustion behavior of chrysanthemum biochar blended with graphite carbon as a heating source for heat-not-burn tobacco.

Heat-not-burn tobacco with an external heating source is a cleaner alternative to conventional cigarettes due to its lower emission of nicotine, CO and tar in the smoke, and the co-combustion of the composite carbon source (chrysanthemum biochar blended with graphite carbon) is a promising carbon heating source for a heat-not-burn tobacco product. This work has investigated the effect of the blending ratio of the graphite carbon on the co-combustion characteristics (, the minimum ignition temperature, the burnout temperature, ) of the composite carbon source, as well as the effect of KCO on the co-combustion behaviors. The results indicate that the minimum ignition temperature is mainly controlled by the ignition of the biochar while the burnout temperature is dominated by that of the graphite.

Novel aluminum vanadate as a cathode material for high-performance aqueous zinc-ion batteries.

Rechargeable aqueous zinc-ion batteries (AZIBs) have garnered widespread attention as a new large-scale energy storage candidate owing to their low cost and high theoretical capacity. Because of the unique divalent state of Znand the existence of a strong electrostatic repulsion phenomenon, researchers are currently focusing on how to prepare high-performance cathode materials. In this study, we synthesized aluminum vanadate (AlVO) as a cathode material for AZIBs using a solvothermal method.

Protective effects of selenium-enriched peptides from against high-fat diet induced obesity and its associated metabolic disorders in mice.

Selenium-enriched peptides from (CSP) have excellent antioxidant functions but little is known about their effects on obesity and associated metabolic disorders in mice fed with a high-fat diet (HFD). In this study, C57BL/6 mice were fed a HFD with or without CSP supplementation (CSPL: 26 μg Se per kg bw per d; CSPH: 104 μg per kg bw per d) for 10 weeks. The results showed that both CSPL and CSPH could ameliorate overweight gain, excess fat accumulation, serum lipid metabolism, and insulin resistance.

[Study on interaction between ginsenosides Rg_1,Rb_1 and Ro and bovine serum albumin].

Small molecules with physiological or pharmacological activities need to interact with biological macromolecules in order to function in the body. As the protein with the highest proportion of plasma protein,serum albumin is the main protein binding to various endogenous or exogenous small molecules. Serum albumin interacts with small molecules in a reversible non-covalent manner and transports small molecules to target sites.
