One-Step Decoration of Subnanometer MoO Clusters on BiVO Nanotubes for Visible-Light-Driven Water Oxidation.

For the sluggish reaction kinetics due to a four-electron transfer process, water oxidation is always a major obstacle to solar splitting of water to hydrogen. It remains a tough challenge to develop efficient nonnoble-metal photocatalysts for water oxidation. Herein, we decorate the host photocatalyst of BiVO nanotubes with the coatalyst of subnanometer MoO clusters (denoted as BiVO/MoO hetero-nanotubes) via a one-step cation-exchange solvothermal reaction using NaVO nanowires as the hard template.

HDACs inhibitors have shown synergistic anticancer effects in combination with LSD1 inhibitors in several types of cancer.

Profiling of Peripheral TRBV and CD4+CD25+ Treg in CHB Patients with HBeAg SC during TDF Treatment.

Highly efficient fluoride removal from water using 2D metal-organic frameworks MIL-53(Al) with rich Al and O adsorptive centers.

In this study, metal-organic framework MIL-53(Al) was synthesized and studied to understand the different mechanisms between normal MIL-53(Al) and 2D metal-organic framework MIL-53(Al) for removing fluoride. Comparatively, the 2D MIL-53(Al) had two-dimensional linear morphology rather than block shape, indicating more expose adsorptive sites than normal MIL-53(Al). The batch adsorption experiments were applied to investigate the performance of 2D MIL-53(Al), including pH, adsorption kinetics, and thermodynamics.

To improve the mass transfer efficiency of poly(m-phenylenediamine) for the effective removal of hexavalent chromium (Cr (VI)) from aqueous solution, a facile and one-step method to prepare two-dimensional poly(m-phenylenediamine) functionalized reduction graphene oxide (rGO-PmPD) by dilution polymerization is developed. The structure and morphology of rGO-PmPD as well as rGO and PmPD were characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), Brunauer-Emmett-Teller (BET), Fourier-transformed infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), Raman, and X-ray diffraction (XRD). The preparation mechanism, adsorption performance, and mechanism of rGO-PmPD were then investigated in detail.

Increasing plasma ADAMTS13 activity is associated with HBeAg seroconversion in chronic hepatitis B patients during 5 years of entecavir treatment.

The relationship between hemostatic system and HBeAg seroconversion (SC) of chronic hepatitis B (CHB) patients is ill-defined. We therefore evaluate the predictive value of plasma ADAMTS13 (a disintegrin and metalloproteinase with a thrombospondin motif repeats 13) and VWF (von Willebrand factor) for CHB patients during 5-year entecavir (ETV) treatment. One hundred and fourteen HBeAg positive CHB patients on continuous ETV treatment were recruited.
