Novel Three-Dimensional Graphene-Like Networks Loaded with FeO Nanoparticles for Efficient Microwave Absorption.

A novel three-dimensional graphene-like networks material (3D-GLN) exhibiting the hierarchical porous structure was fabricated with a large-scale preparation method by employing an ion exchange resin as a carbon precursor. 3D-GLN was first studied as the effective microwave absorbing material. As indicated from the results of the electromagnetic parameter tests, and the minimum reflection loss () of the 3D-GLN reached -34.

Size-controlled Ag quantum dots decorated on binder-free hierarchical NiCoP films by magnetron sputtering to boost electrochemical performance for supercapacitors.

This paper reports novel binder-free and self-supported electrodes of hierarchical nickel-cobalt phosphide (NiCoP) films decorated with size-controlled Ag quantum dots by magnetron sputtering (Ag/NiCoP). Ag quantum dots with an average particle size of 7.90 nm uniformly distribute over the nanosheet-assembled architecture of NiCoP films.

Enhanced magnetostriction derived from magnetic single domain structures in cluster-assembled SmCo films.

Cluster-assembled SmCo alloy films were prepared by low energy cluster beam deposition. The structure, magnetic domain, magnetization, and magnetostriction of the films were characterized. It is shown that the as-prepared films are assembled in compact and uniformly distributed spherical cluster nanoparticles, most of which, after vacuum in situ annealing at 700 K, aggregated to form cluster islands.

Therapeutic Effects of CUR-Activated Human Umbilical Cord Mesenchymal Stem Cells on 1-Methyl-4-phenylpyridine-Induced Parkinson's Disease Cell Model.

The purpose of this study is to evaluate the therapeutic effects of human umbilical cord-derived mesenchymal stem cells (hUC-MSC) activated by curcumin (CUR) on PC12 cells induced by 1-methyl-4-phenylpyridinium ion (MPP+), a cell model of Parkinson's disease (PD). The supernatant of hUC-MSC and hUC-MSC activated by 5 µmol/L CUR (hUC-MSC-CUR) were collected in accordance with the same concentration. The cell proliferation and differentiation potential to dopaminergic neuronal cells and antioxidation were observed in PC12 cells after being treated with the above two supernatants and 5 µmol/L CUR.

The expression and distributions of ANP32A in the developing brain.

Acidic (leucine-rich) nuclear phosphoprotein 32 family, member A (ANP32A), has multiple functions involved in neuritogenesis, transcriptional regulation, and apoptosis. However, whether ANP32A has an effect on the mammalian developing brain is still in question. In this study, it was shown that brain was the organ that expressed the most abundant ANP32A by human multiple tissue expression (MTE) array.

[Expression and significance of c-Jun activation domain binding protein 1 in human colorectal carcinoma].

Objective: To explore the association of Jab1 (c-Jun activation domain binding protein 1) expression during carcinogenesis and clinicopathological characteristics of colorectal carcinoma (CRC) .

Methods: Tissue specimens were obtained from 80 cases of CRC from January 2007 to December 2008. And the expression of Jab1 protein for each specimen was detected by immunohistochemistry (EnVision).

Structure and luminescence properties of eu3+-doped cubic mesoporous silica thin films.

Eu3+ ions-doped cubic mesoporous silica thin films with a thickness of about 205 nm were prepared on silicon and glass substrates using triblock copolymer as a structure-directing agent using sol-gel spin-coating and calcination processes. X-ray diffraction and transmission electron microscopy analysis show that the mesoporous silica thin films have a highly ordered body-centered cubic mesoporous structure. High Eu3+ ion loading and high temperature calcination do not destroy the ordered cubic mesoporous structure of the mesoporous silica thin films.

Structure and optical properties of ordered mesoporous titania-silica composite thin films.

Highly ordered mesoporous titania-silica (TiO2-SiO2) composite thin films have been prepared by spin-coating technique using poly(alkaline oxide) triblock copolymers EO20PO70EO20 (P123) as structure-directing agent. Low-angle X-ray diffraction analysis shows that the mesoporous composite thin films remain a long range periodic ordered structure even if the TiO2/SiO2 ratio in the thin films is as high as 80%. Wide-angle X-ray diffraction analysis reveals that the average grain size of TiO2 increases from 2.

Structure and Photoluminescent Properties of ZnO Encapsulated in Mesoporous Silica SBA-15 Fabricated by Two-Solvent Strategy.

The two-solvent method was employed to prepare ZnO encapsulated in mesoporous silica (ZnO/SBA-15). The prepared ZnO/SBA-15 samples have been studied by X-ray diffraction, transmission electron microscope, X-ray photoelectron spectroscopy, nitrogen adsorption-desorption isotherm, and photoluminescence spectroscopy. The ZnO/SBA-15 nanocomposite has the ordered hexagonal mesostructure of SBA-15.
