Mesoporous silica core–shell composite functionalized with polyelectrolytes for drug delivery

Room temperature ethanol sensor with sub-ppm detection limit: Improving the optical response by using mesoporous silica foam

“…4.a: A and B). Both measurements clearly show the pore structure; in the latter case the peaks at h = 0.705, 1.235 and 1.41 nm −1 correspond to the 1: √ 3:2 ratio, thereby the P6 mm sym- metry is clearly identified [46]. The double logarithmic plot of the scattering curve is suitable for determining the fractal properties of the material.…”

Polystyrene core–silica shell composite particles: effect of mesoporous shell structures on oxide CMP and mechanical stability

“…5b) of the composites-B shows a sharp peak in the diffractogram in around 2q ¼ 2-3 and a weak intensity peak in 2q ¼ 4-5 , which indicates that these samples exhibit a typical feature of radial mesoporous structures. 19 In the case of composites-A, the distinct diffraction peaks cannot be found in Fig. 5b, while the major peak is shied to a low angle and the peak relative intensity is signicantly reduced.…”

Silica-Based Catalyst Supports Are Inert, Are They Not?: Striking Differences in Ethanol Decomposition Reaction Originated from Meso- and Surface-Fine-Structure Evidenced by Small-Angle X-ray Scattering

“…3/A). The SBA-15 silica shows a strong (100) and two weak (110) and 200peaks (the ratio of the values belonging to the peaks is 1:√3:2), implying a high degree of twodimensional hexagonal (P6mm) structure 24 (Fig. 1/B.…”
