Preparation of Novel Mesoporous Silica Using a Self-Assembled Graphene Oxide Template.

Novel mesoporous silicas rolled with silica sheets with 2D regular spacing were prepared using a self-assembled graphene oxide (GO) template formed by mixing GO with Pluronic123 (P123). Self-assembled GO templated mesoporous silicas (SGT-PMS) showed well-developed X-ray diffraction peaks with d-spacings of 9.8-10.

Preparation of Mesoporous Silica by Nonionic Surfactant Micelle-Templated Gelation of NaSiO and HSiF and Application as a Catalyst Carrier for the Partial Oxidation of CH.

Mesoporous silica (MSPN12) was prepared by nonionic surfactant micelle-templated gelation of sodium silicate (NaSiO) and fluorosilicic acid (HSiF) in aqueous solution, characterized by a range of instrumental techniques, and tested as a support for Ni and Rh catalysts in the partial oxidation of methane (POM). Calcined and sintered MSPN12 exhibited well-defined d-spacings (3.5-4.

Preparation of cubic SiC from δ-NaSiO/carbon nanocomposite using cobalt catalyst.

Silicon carbide (SiC) was prepared by carbothermal reduction of a crystalline-layered sodium silicate (δ-NaSiO)/carbon nanocomposite (LCN), which contained a stacked carbon film embedded with cobalt between the silicate layers. Subsequent sintering of this mixture for 3 h at 1000-1350°C resulted in the formation of graphitic carbon and SiC. Meanwhile, sintering without a cobalt catalyst resulted in the formation of graphitic carbon, regardless of the temperature.

Mucosal Immunity Related to FOXP3 Regulatory T Cells, Th17 Cells and Cytokines in Pediatric Inflammatory Bowel Disease.

Background: We aimed to investigate mucosal immunity related to forkhead box P3 (FOXP3) regulatory T (Treg) cells, T helper 17 (Th17) cells and cytokines in pediatric inflammatory bowel disease (IBD).

Methods: Mucosal tissues from terminal ileum and colon and serum samples were collected from twelve children with IBD and seven control children. Immunohistochemical staining was done using anti-human FOXP3 and anti-RORγt antibodies.

Mesoporous silica-pillared H(+)-kenyaite with highly ordered gallery structure.

Mesoporous silica-pillared H(+)-kenyaite (SPK) derivatives with highly ordered gallery structure and thermal resistance were prepared by the hydrolysis of TEOS (tetraethylorthosilicate) in interlayer space, using DDA (dodecylamine) as catalyst and template. DDA-TEOS/H(+)-kenyaite intercalation compounds were obtained by the dispersion of H(+)-kenyaite in DDA-TEOS solution. DDA-TEOS/H(+)-kenyaites were hydrolyzed rapidly in pure water, forming siloxane pillared H(+)-kenyaites.

Selective uranyl ion detection by polymeric ion-selective electrodes based on salphenH2 derivatives.

The new ion-selective electrodes (ISEs) based on salphenH2 derivatives such as N,N'-(propylenedioxy)benzenebis(salicylideneimine) L1 and N,N'-4,5-(propylenedioxy)benzenebis(3,5-di-tert-butylsalicylideneimine) L2 as cation carriers are developed for a uranyl ion. The combination of these new ionophores with tris(2-ethylhexyl)phosphate (TEHP) as a plasticizer particularly shows near Nernstian slope in the wide concentration range (1.0 x 10(-6) to 1.
