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

Highly ordered mesoporous polymer−silica and carbon−silica nanocomposites with interpenetrating networks have been successfully synthesized by the evaporation-induced triconstituent co-assembly method, wherein soluble resol polymer is used as an organic precursor, prehydrolyzed TEOS is used as an inorganic precursor, and triblock copolymer F127 is used as a template.

Mesoporous silica is a porous material with walls made of silica and pores in the size range of 2-50 nm. Since the silica most often is amorphous, the material lacks short range order but the pores may be arranged in different structures generating a long-range order. The main objective of this project has been to study and develop syntheses of mesoporous silica suitable for large scale

PubChem Substance ID 24878510. NACRES NA.23 Mesostructured silica thin films and particles prepared by surfactant‐templated sol–gel techniques are highly versatile substrates for the formation of functional materials. The ability to deliberately place molecules possessing desired activities in specific spatially separated regions of the nanostructure is an important feature of these 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 MSNs.

NACRES NA.23 Mesostructured silica is a material consisting of a silica matrix with an organization in the meso range of 2-50 nm. The silica matrix is most often amorphous while the organization, induced by a structure directing agent, may generate a long-range mesoorder. The main objective of this project has been to investigate syntheses of mesostructured silica using non-ionic block co-polymers as Since its discovery in 1992, mesostructured silicate particles have been a subject of intensive research due to the large surface areas of the materials and the simplicity in modifying both the particle and the pore size. 38, 39 Various organic templates (e.g., cationic surfactants and triblock copolymers) and pore swelling agents have successfully been used in the particle synthesis to give a wide range of well‐defined pore sizes and mesostructures.
