Zeolites are the catalytic materials that widly applied in processing of conventional and renewable fuels chemicals. The present study provides a comprehensive analysis factors controlling acidic medium synthesis high silica silicalite-1 zeolite. effect various sources (TEOS, fumed colloidal silica) alkali metal cations (Na K) on formation is studied. efficiency different types seeds (micron-si...

In this paper, a planar monopole antenna is introduced, also we added some new Nano fillers such as Fumed Silica and Aluminum Oxide to RT Duriod5880 and RO3003 to produce new Nano composite materials, then new Nano composite materials are used as a substrate of a ultra-wideband monopole antenna. Antenna characteristics are considered to illustrate that, by using these Nano composite materials, ...

Electrostatic spray ionization (ESTASI) mass spectrometry imaging (MSI), recently developed to profile spatial distribution of chemical and biochemical molecules on an insulating surface under ambient conditions, has been applied to identify and quantify chemicals from silica gel surfaces. Both hydrophilic or hydrophobic silica plates have been imaged with good resolution providing a direct ide...

The adsorption from mixed polyelectrolyte-surfactant solutions at hydrophobized silica surfaces was investigated by in situ null-ellipsometry, and compared to similar measurements for hydrophilic silica surfaces. Three synthetic cationic copolymers of varying hydrophobicity and one cationic hydroxyethyl cellulose were compared in mixtures with the anionic surfactant sodium dodecylsulfate (SDS) ...

A facile self-assembly method is described to prepare PEGylated silica nanocarriers using hydrophobic mesoporous silica nanoparticles and a pluronic F127 polymer. Pluronic capped nanocarriers revealed excellent dispersibility in biological media with cyto- and blood compatibilities.

Ready transformation and reactivity is observed at the nanoscale. Silica/silicon (SiOx) nanospheres of diameter %30 nm generated from equimolar Si/SiO2 mixtures are found to display enhanced catalytic and reactive properties relative to commonly employed silica support surfaces including fumed silica. A unique oxygen deficient synthesis has been used to generate SnO2Kx nanowires, nanoribbons, a...
