Graphic carbon nitride polymer was modified with transition bimetals compounds by impregnation ofpre-prepared g-C3N4 in aqueous solution of ammonium molybdate and vanadate. The prepared hybridmaterial was characterized by XRD, SEM, TEM, FT-IR, XPS and N2 adsorption–desorption techniques todetermine its surface morphology, composition and structure. The results revealed that VOx-MoOy singlemolecular layer incorporated into g-C3N4 molecule framework by interaction between host and guestwas fabricated. The hybrid composite was employed as catalyst for styrene oxidation to benzaldehydeusing molecular oxygen as oxidant. The results indicated that the composite was highly active and selectivefor styrene oxidation, giving TON 458.8 mol/mol(Mo+V) and 96.7% selectivity to benzaldehyde. Thecorrelation between high activity and surface properties the catalyst was explored.

A series of novel effector molecules secreted by the type three secretion system (T3SS) of Shigella spp. have been reported in recent years. In this study, a proteomic approach was applied to study T3SS effectors systematically. First, proteins secreted by the S. flexneri wildtype strain after Congo Red induction were separated and identified using two-dimensional electrophoresis to display the relative abundance of all kinds of early effectors for the first time. Then, a gene deletion mutant of known virulence repressor (OspD1) and a gene overexpressed mutant of two known virulence activators (MxiE and IpgC) were constructed and analyzed to discover potential late effectors. Furthermore, the supernatant proteins of gene deletion mutants of two known translocators (IpaB and IpaD), which would constantly secrete effectors, were also analyzed. Among all of the secreted proteins identified in our study, IpaH1.4, IpaH_5, and IpaH_7 have not been reported before. These proteomics data of the secreted effectors will be valuable to understand the pathogenesis of S. flexneri.

The aim of this study was to evaluate the effects of the Zhizhu decoction on gastric emptying and gastric mucosal protection. The Zhizhu decoction is composed of Aurantii fructus and Atractylodes macrocephala Rhizoma. Results showed that oral administration of the Zhizhu decoction accelerated gastric emptying in mouse and protected gastric mucosa from ethanol-induced ulcers in rat. Our investigations demonstrated that the Zhizhu decoction accelerated gastric emptying, at least in part, by activating the muscarinic and 5-HT3 receptors. The gastroprotective effect is involved in its antioxidant effects and increased vascular endothelial growth factor expression.

<P><B>Abstract</B></P> <P>Herein, we report a successful synthesis of porous TiO<SUB>2</SUB> monoliths decorated with unique nanoplate, nanoprism, and nanopyramid-shaped CdSe particles through a mild selenylation of CdO embedded inside porous TiO<SUB>2</SUB> monoliths via a hydrothermal method in a very controlled manner. Compared with pure TiO<SUB>2</SUB>, as-synthesized CdSe/TiO<SUB>2</SUB> photocatalyst not only enhances light absorption but also leads to a highly efficient charge-carrier separation. Particularly, the nanoplate-shaped 7% CdSe/TiO<SUB>2</SUB> photocatalyst (molar percentages of CdSe to TiO<SUB>2</SUB> is 7:100) exhibits an exceptional hydrogen evolution rate up to 3650 μmol h<SUP>−1</SUP> g<SUP>−1</SUP> without resorting to any noble-metal co-catalysts under visible-light irradiation owing to synergistic effects envisaged by a rational material design. Our results may provide a useful strategy to develop a highly-efficient visible-light-driven hydrogen production system via water splitting.</P>

High nickel ternary cathode materials (Ni ≥ 90%) have great potential for application as power batteries in electric vehicles and have become a hot spot for research on cathode materials. However, the residual Li on the surface of the high Ni ternary cathode materials prepared by solid-phase sintering is one of the main reasons affecting their electrochemical performance. It is found that Li1 + x(Ni0.9Co0.05Mn0.05)1-xO2 with x = 0.3, which has a discharge-specific capacity of 205.74 mAh g −1 at 2.7–4.3 V, 0.1C and 184.1 mAh g −1 at 1 C, retained 89% of its initial discharge capacity after 100 cycles at 1 C. The discharge-specifi c capacity at 10 C was 153.14 mAh g −1. In addition, the Li residue of NCM90-1.03 was 17,189.959 ppm, and the total alkalinity was 4196.896 ppm. The results by X-ray diff raction (XRD) and scanning electron microscope (SEM) showed that when the Li excess was 0.3%, it was possible to obtain uniform particle size, a wider Li layer, and reduced cation mixing. Therefore, choosing the right amount of excess Li can stimulate the application prospect of NCM90 in new energy vehicles.

<P><B>Abstract</B></P> <P>It is well known that both catalytic efficiency and stability are the two important parameters of photocatalysts for visible-light-driven hydrogen production reactions. However, light-driven hydrogen evolution based applications still suffer from sluggish reaction kinetics due to the lack of high-performance photocatalysts. In this paper, we successfully synthesized a ternary porous CdS/WO<SUB>3</SUB>/TiO<SUB>2</SUB> photocatalyst with high efficiency and stability via two-stage approach. The as-prepared samples are characterized by XRD, FESEM, EDS, TEM, XPS, and UV–Vis, respectively, which illustrated that the CdS and WO<SUB>3</SUB> moieties are in-situ formed inside the porous TiO<SUB>2</SUB>. Particularly, the photocatalytic hydrogen (H<SUB>2</SUB>) evolution rate of such ternary 8% CdS/WO<SUB>3</SUB>/TiO<SUB>2</SUB> (molar ration of CdS:WO<SUB>3</SUB>:TiO<SUB>2</SUB> = 8:8:100) photocatalyst ranges up to 2106 μmol h<SUP>−1</SUP> g<SUP>−1</SUP> under visible-light irradiation, which is higher than that of pure TiO<SUB>2</SUB> and other binary (CdS/TiO<SUB>2</SUB> and WO<SUB>3</SUB>/TiO<SUB>2</SUB>) porous photocatalysts. The superior H<SUB>2</SUB> evolution efficiency can be attributed to the coexistence of CdS and WO<SUB>3</SUB> in porous TiO<SUB>2</SUB> which can promote the interfacial charge transfer and separation as well as extend the light absorption up to the visible range.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Highly efficient and stable photocatalytic activity of CdS/WO<SUB>3</SUB>/TiO<SUB>2</SUB> photocatalysts were synthesized by a two-step method. </LI> <LI> CdS and WO<SUB>3</SUB> inlaid on porous TiO<SUB>2</SUB> can extend the light absorption and enhance photogenerated electron-hole pairs separation. </LI> <LI> The porous structure can provide more reaction active sites and improve photoproduced-electrons and holes transport speed. </LI> </UL> </P> <P><B>Graphical Abstract</B></P> <P>[DISPLAY OMISSION]</P>
