ILC, ionic liquid mesoporous carbon.

Based on the results mentioned above, we propose a sketch for the preparation of mesoporous anatase TiO2. First, complex forms between tetrabutyltitanate and acetylacetone in ethanol. After introduction of aqueous of ammonia sulfate and urea, hydrolysis of tetrabutyltitanate would occur slowly, and sol of TiO2 forms. Then, crystallization proceeds under the hydrothermal conditions. After washing, the mesoporous crystalline anatase TiO2 is obtained. Calcination process facilitates the formation of bigger TiO2 crystal through combination of the small crystal in TiO2. This leads to the formation of bigger mesopores between big TiO2 crystals in TiO2 sphere. Much higher temperature such as 600 °C results in the collapse of mesoporous structure.

Study of Mesoporous Silica Nanoparticles as …

The advanced properties of mesoporous silica have been demonstrated in applications which include chemical sensing, filtration, catalysis, drug-delivery and selective biomolecular uptake. These properties depend on the architectural, physical and chemical properties of the material, which in turn are determined by the processing parameters in evaporation-induced self-assembly. In this study, we introduce a combinatorial approach for the removal of the high molecular weight proteins and for the specific isolation and enrichment of low molecular weight species. This approach is based on Mesoporous Silica Chips able to fractionate, selectively harvest and protect from enzymatic degradation, peptides and proteins present in complex human biological fluids. We present the characterization of the harvesting properties of a wide range of mesoporous chips using a library of peptides and proteins standard and their selectivity on the recovery of serum peptidome. Using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, we established the correlation between the harvesting specificity and the physico-chemical properties of mesoporous silica surfaces. The introduction of this mesoporous material with fine controlled properties will provide a powerful platform for proteomics application offering a rapid and efficient methodology for low molecular weight biomarker discovery.

Mesoporous Silica: An Alternative Diffusion Controlled …

The thickness and porosity of the obtained films were measured with a variable angle spectroscopic ellipsometer (J. A. Woollam Co. M-2000DI). Ellipsometric values, Δ and ψ were measured in the 300-1000nm range at three incidence angles, 55°, 60°, 65°, respectively, and fitted using the Effective Medium Approximation (EMA) model with WVASE32 software. The surface area and pore size of the mesoporous films were measured using N2 adsorption-desorption isotherms on a Quantachrome Autosorb-3B Surface Analyzer. Nanopore size distributions were calculated from the adsorption branch of the isotherms using Barrett-Joiner-Halenda (BJH) model. Contact angles of film surface were measured by a goniometer with captive bubble contact angle measurement.
