Mesostructured silica

Carbon nanotubes (CNTs)/mesostructured silica core-shell nanowires with a carbon nanotube core and controllable highly ordered periodic mesoporous silica shell are syntheiszed via the interfacial Mesostructured layered silicas have been prepared through a surfactant-assisted procedure using neutral alkylamines as templates and starting from atrane complexes as hydrolytic inorganic precursors. By adjusting the synthetic parameters, this kinetically controlled reproducible one-pot method allows for obtaining both pure and functionalized (inorganic or organically) lamellar silica Because the mesostructured silica has a refractive index of only 1.43, silicon wafers (refractive index 3.5) coated with mesoporous silica were used as substrates; mesoporous silica is an excellent 2020-02-07 · Mesostructured cellular foam silica (MCF) is a material with a 3-dimensional pore structure of large cells interconnected by narrower mesporous pores, has attracted much attention for potential applications as versatile catalysts and catalyst supports, template and separation materials because of its appealing pore structure and high surface area, and appreciable thermal and hydrothermal A sigmoidal in vitro release of FITC-R8 from mesostructured silica into phosphate buffered saline (PBS, pH 7.4) was observed and the typical release duration was 5 days at 37 ‹C. Release from the reservoir yielded significant elongation in duration of the FITC signals in DU145 cells by confocal microscopic analysis, compared with a single administration of FITC-R8. Magnetically separable mesostructured silica with an unobstructed pore system was fabricated through the deposition of cobalt nanoparticles on the outer surface of the submicron-sized silica particles. These cobalt nanoparticles were further protected by a nanometer-thick carbon shell against acid e … We have incorporated the photochromic dyes spiropyran and spirooxazine in surfactant templated mesostructured silica particles.

These cobalt nanoparticles were further protected by a nanometer-thick carbon shell against acid e … We have incorporated the photochromic dyes spiropyran and spirooxazine in surfactant templated mesostructured silica particles. Spherical inorganic–organic hybrid pigments with varying dye content were produced by a one-pot synthesis in an aerosol reactor where the internal mesostructure could be controlled. Generally speaking, the synthesis of mesostructured materials can be controlled through altering the surfactant type (ionic or non-ionic) and the interaction mechanism between the template (if employed) and silica components. 1,2 M41S silica molecular sieves were initially synthesized under alkaline conditions, where the anionic inorganic species (I −) become stable in the presence of the Poor permeation across intestinal mucous barriers often limits the oral delivery of prospective therapeutic proteins and peptides (TPPs).
