China), Fax: (+86) 216-432-280 Highly active Ni-promoted mesostructured silica nanoparticles for CO 2 methanation P. Triwahyono IntroductionRecycling of CO 2 as a carbon source for chemicals and fuels should be considered as a more sustainable use of resources which may indeed lead to reduced consumption of carbon-based fossil resources without producing more CO 2 from the whole system. Abstract: Mesoporous silica nanoparticles (MSNs) have garnered a great deal of attention as potential carriers for therapeutic payloads. Here, we report a pH-responsive drug-carrier based on chondroitin sulfate functionalized mesostructured silica nanoparticles (NMChS-MSNs) ie, the amidation between NMChS macromer and amino group functionalized silica nanoparticles Amino functionalized ordered mesoporous silica nanoparticles (NH 2-MSNs) were prepared according to literature procedures using cetyltrimethylammoniumbromide (CTAB) as a structure Organo-functionalised mesostructured silica nanoparticles were prepared by surfactant templating under alkaline conditions using a quenching technique described in detail elsewhere.12,13 In this work, NiO supported mesostructured silica nanoparticles (MSN) were synthesized via the urea–nitrate combustion method using urea as fuel and nitrate salts as oxidants with the different urea/nitrate ratios and calcination duration. The physicochemical properties of catalysts were investigated by several techniques, including N2 physisorption measurements, powder X-ray diffraction, N2 The surface of α-Fe2O3 nanoparticles was successfully coated with mesostructured silica templated by surfactant assemblies using cetyltrimethylammonium ions. By repeating the coating operation, it was possible to control the thickness of the mesostructured silica phase.

A simple one-pot synthesis process for functionalized mesostructured silica nanoparticles (MSNP) is reported. The novel process demonstrated the possibility to achieve MSNP with a surface area up to 501 m 2.g −1 using a phosphonate based nonsilane precursor such as N, N´-bis [4,6-bis (diethylphosphono)-1,3,5-triazin-yl]-1,2-diaminoethane (ED).

Synthesis and Characterization of Mesostructured Cellular Foam (MCF) Silica Loaded with Nickel Nanoparticles as a Novel Catalyst 54 . a graph known as an adsorption isotherm, whilst desorp- tion isotherm was obtained by measuring the quantities of nitrogen desorbed from the sample as the relative pressure was gradually lowered. Here, we developed perfluorocarbon-loaded ultraporous mesostructured silica nanoparticles (PERFUMNs) as 19 F MRI detectable oxygen-sensing probes. Ultraporous mesostructured silica nanoparticles (UMNs) have large internal cavities (average = 1.8 cm 3 g –1 ), facilitating an average 17% loading efficiency of PFCs, meeting the threshold fluorine concentrations needed for imaging studies.

One of the major challenges in medicine is the delivery and control of drug release over time. Current approaches take advantage of mesostructured silica nanoparticles (MSNs) as carriers but suffer several problems including complex synthesis that requires sequential steps for (1) removal of surfactants and (2) functionalization of MSNs to allow upload of the drugs. 2020-05-25 Transformation of Mesostructured Silica Nanoparticles into Colloidal Hollow Nanoparticles in the Presence of a Bridged-Organosiloxane Shell .
