Highly Dispersed Vanadia Anchored on Protonated g-CN as an Efficient and Selective Catalyst for the Hydroxylation of Benzene into Phenol.

The direct hydroxylation of benzene is a green and economical-efficient alternative to the existing cumene process for phenol production. However, the undesired phenol selectivity at high benzene conversion hinders its wide application. Here, we develop a one-pot synthesis of protonated g-CN supporting vanadia catalysts (V-pg-CN) for the efficient and selective hydroxylation of benzene.

Encapsulating MnO Nanorods in a Shell of SiO Nanobubbles for Confined Fenton-Type Catalysis.

Core-shell structured nanomaterials with delicate architectures have attracted considerable attention for realizing multifunctional responses and harnessing multiple interfaces for enhanced functionalities. Here, we report a controllable synthesis of core-shell structured MnO@SiONB nanomaterials consisting of MnO nanorods covered with a shell of SiO nanobubbles. A series of MnO@SiONB catalysts with tunable secondary structures can be synthesized by simply tuning the feeding ratio and the modification conditions.

A vascular disrupting agent overcomes tumor multidrug resistance by skewing macrophage polarity toward the M1 phenotype.

Multidrug resistance (MDR) mediated by ATP-binding cassette (ABC) transporters is the major obstacle for chemotherapeutic success. Although attempts have been made to circumvent ABC transporter-mediated MDR in past decades, there is still no effective agent in clinic. Here, we identified a vascular disrupting agent, Z-GP-DAVLBH, that significantly inhibited the growth of multidrug-resistant human hepatoma HepG2/ADM and human breast cancer MCF-7/ADR tumor xenografts, although these cells were insensitive to Z-GP-DAVLBH in vitro.

Pericyte-targeting prodrug overcomes tumor resistance to vascular disrupting agents.

Blood vessels in the tumor periphery have high pericyte coverage and are resistant to vascular disrupting agents (VDAs). VDA treatment resistance leads to a viable peripheral tumor rim that contributes to treatment failure and disease recurrence. Here, we provide evidence to support a hypothesis that shifting the target of VDAs from tumor vessel endothelial cells to pericytes disrupts tumor peripheral vessels and the viable rim, circumventing VDA treatment resistance.

Effect of organic loading rate on dark fermentative hydrogen production in the continuous stirred tank reactor and continuous mixed immobilized sludge reactor from waste pastry hydrolysate.

Waste pastry (6%, w/v) was hydrolyzed by the produced glucoamylase and protease to obtain the glucose (19.8g/L) and free amino nitrogen (179mg/L) solution. Then, the effect of organic loading rate (OLR) (8-40kgCOD/(md)) on dark fermentative hydrogen production in the continuous stirred tank reactor (CSTR) and continuous mixed immobilized sludge reactor (CMISR) from waste pastry hydrolysate was investigated and compared.

In vitro and in vivo antiangiogenic activity of desacetylvinblastine monohydrazide through inhibition of VEGFR2 and Axl pathways.

Tumor angiogenic process is regulated by multiple proangiogenic pathways, such as vascular endothelial growth factor receptor 2 (VEGFR2) and Axl receptor tyrosine kinase (Axl). Axl is one of many important factors involved in anti-VEGF resistance. Inhibition of VEGF/VEGFR2 signaling pathway alone fails to block tumor neovascularization.

Bis[μ-5-(5-carboxyl-ato-3-pyrid-yl)tetra-zolato-κN,N:N]bis-[triaqua-zinc(II)].

In the title complex, [Zn(2)(C(7)H(3)N(5)O(2))(2)(H(2)O)(6)], the 5-(5-carboxyl-ato-3-pyrid-yl)tetra-zolate ligand chelates the Zn(II) center through one pyridyl N and one tetra-zolate N atom, and uses another N atom to bridge to the second Zn atom, forming a centrosymmetric dinuclear unit. Three coordinated water mol-ecules complete the distorted octa-hedral geometry of the Zn(II) atom. O-H⋯O and O-H⋯N hydrogen bonds involving the coordinated water mol-ecules, tetra-zolate N atoms and the carboxyl-ate group result in a three-dimensional structure.

Diaqua-bis[5-(5-carboxy-2-pyridyl)tetra-zolato-κN,N]cadmium(II) dihydrate.

In the title complex, [Cd(C(7)H(4)N(5)O(2))(2)(H(2)O)(2)]·2H(2)O, the water-coordinated Cd(II) atom ( symmetry) is coordinated by four N atoms from two symmetry-related 3-carboxy-pyidyl-6-tetra-zolato ligands, forming a distorted octa-hedral complex. The uncoordinated water mol-ecules connect the mononuclear units into a layer structure through O-H⋯N and O-H⋯O hydrogen bonds; similar hydrogen bonds between coordinated water mol-ecules and anionic groups result in a three-dimensional structure.

[Hydrothermal synthesis and luminescence of one-dimensional Mn(2+)-doped CdS nanocrystals].

One-dimensional Mn(2+)-doped CdS nanocrystals were synthesized by the hydrothermal route. The products were characterized by SEM, EDS, XRD, TEM, HRTEM and PL, respectively. The results revealed that dopant Mn2+ completely substitutes Cd2+ in CdS nanocrystals, and the product was of good crystallite.

[Preparation and spectral properties of PVP-modified CdS nanorods].

Polyvinylpyrrolidone (PVP)-modified CdS nanorods were prepared by a hydrothermal reaction of CdCl2 2.5H2O and (NH4)2S with 10 wt% ethylenediamine aqueous solution as solvent and 1.0 wt% PVP as additives.
