ABSTRACT Cytochrome P450 BM-3, a self-sufficient enzyme from Bacillus megaterium that catalyzes the subterminal hydroxylation of long-chain fatty acids, has been engineered into catalyst for oxidation polycyclic aromatic hydrocarbons. The activities triplet mutant (A74G/F87V/L188Q) towards naphthalene, fluorene, acenaphthene, acenaphthylene, and 9-methylanthracene were 160, 53, 109, 287, 22/min, respectively. Compared with wild type these hydrocarbons, those improved by up to 4 orders...
It was disclosed in our group for the first time that flavonoids Lonicera japonica Thunb. are related to its therapy gastric ulcer. Based on this finding, 20 were selected Helicobacter pylori urease inhibitory activity evaluation, and quercetin showed excellent potency with IC(50) of 11.2 ± 0.9 μM. Structure-activity relationship analysis revealed removal 5-, 3-, or 3'-OH led a sharp decrease activity. Thus, 3- 5-OH as well 3',4'-dihydroxyl groups believed be key structural characteristics...
Various studies have shown that soils surrounding mining areas are seriously polluted by heavy metals. In this study, 58 topsoil samples were systematically collected throughout the coal city Wuhai, located within Inner Mongolia Autonomous Region of China. The concentrations As, Hg, Cr, Ni, Cu, Zn, Cd, and Pb in these measured statistically analyzed. mean all metals lower than their Grade I values defined Chinese Soil Quality Standard. However, individual many exceeded background values....
In this study, the effects of disperse blue dye-sensitization on photocatalytic properties Ag-N co-doped TiO2 nanoparticles loaded polyethylene terephthalate (PET) filaments are investigated under visible light irradiation. The microstructure and as-synthesized nanocomposites, as well as-prepared PET filaments, systematically characterized. performance coated with sensitized dyes is evaluated via its capacity photo-degrading methyl orange (MO) It found that holes predominant reactive radical...
Abstract: Cornus wilsoniana Wanger is a woody oil plant distributed in the south region of Yellow River, China. Its has been taken as edible for over 100 y, and consumption such believed to prevent hyperlipidemia Chinese folk recipe. This study investigated hypolipidemic effect (CWO) Sprague–Dawley rats. The results demonstrated that CWO could significantly decrease total cholesterol (TC), triacylglycerol (TG), low‐density lipoprotein (HDL‐C) serum, liver weight, hepatic TC, TG. After...
WPU/CNT/GO nanocomposites were prepared with waterborne polyurethane (WPU), grapheme (GO) and carbon nanotubes (CNT) as main materials modified by (3-Aminopropyl) triethoxysilane (APTES). The morphologies composite physical states investigated using scanning electron microscopy (SEM), thermogravimetry analysis (TG) fourier transform infrared spectroscopy (FTIR). Scanning observations revealed that GO had good compatibility WPU whereas CNT slight agglomeration. Results from FTIR TG suggested...
Various studies have shown that the heavy use of pharmaceuticals poses serious ecological risks, especially in metropolitan areas with intensive human activities. In this study, spatial distribution, sources, and risks 29 82 surface waters collected from North Canal Basin Beijing were studied. The results showed pharmaceutical concentrations ranged not detected to 193 ng/L, ampicillin being undetected while ofloxacin had a 100% detection frequency, which indicates widespread occurrence...

Abstract Zinc‐air batteries (ZABs) have garnered significant attention due to their high theoretical energy density, safety, and environmental sustainability. However, the slow oxygen reduction reaction (ORR) kinetics at cathode remains a major challenge for improving ZAB performances. In this study, ABO 3 ‐type perovskite transition metal oxides, particularly LaMnO , are explored as potential nonprecious catalysts address these limitations. work, catalyst was prepared using sol‐gel method,...
Abstract Degradation behavior of ZnO‐glass fiber‐unsaturated polyester composite under exposure to a metal halide lamp is investigated by means DSC and FTIR. The FTIR results show that the UV photons can increase carbonyl group on surface, but ZnO decrease content further contribute breaking single bond carbon oxygen surface. All indicate for pure unsaturated in air, major reaction photo‐initiated oxidation, whereas composites with ZnO, decarbonylation effect. In addition, when not higher...
In recent years, with the gradual deterioration of air quality and more frequency haze weather phenomenon, it intrudes into human body brings great harm to health when people are unprepared. The basic theory that anion could purify eliminate positive ion explains balata modified bitumen reduce PM2.5, number pavement release relates purification. At same time, building materials plaza many functions were designed which can negative ions, PM2.5 particles, decompose harmful components fuel...
