Evaluation of molecular volume of siloxane bonding and phenyl group in partially phenylated organic/inorganic hybrid glass

Nanocomposites of poly(m‐xylene diamide) with polyhedral oligomeric silsesquioxane, montmorillonite, and their combination: Structure and properties

“…showed that a minimum reinforcing effect is observed if the thickness of the shell exceeds 25% of the radius of the core. In relation to this work, the molecular radius for the phenyl group attached to the POSS molecule is approximately 3.1 Å [48] whilst the diameter of the organic silicon core is ∼15 Å. Therefore the phenyl shell only accounts for 20% of the core and the trend in modulus after introduction of the dodecaphenyl‐POSS correlate well with this approach.…”

Fabrication of microporous amorphous silica glass by pyrolysis of phenyl groups intercalated in sol–gel derived phenyl-modified silica glass

“…0.31 nm) [31]. Here, the molecular radius of phenyl was estimated by the helium pichnometry technique, as previously reported by our group [31]. This agreement allows us to consider the formation of micropores as the voids, generated after the complete oxidative elimination of the phenyl groups.…”

“…7 is in good agreement with the molecular radius of a phenyl (ca. 0.31 nm) [31]. Here, the molecular radius of phenyl was estimated by the helium pichnometry technique, as previously reported by our group [31].…”

“…Here, the values of the density of the siloxane and phenyl moieties were given as 2.2× 10 3 kg/m 3 and 1.04 × 10 3 kg/m 3 as estimated in our previous study, respectively [31]. Fig.…”

Properties and microstructure of silica glass incorporated with tributyl phosphate by sol–gel method

“…In the solgel preparation scheme, the organic additive can be homogeneously mixed at the initial liquid state with the silica source. There have been a number of works of the incorporation of functional organic substances or dyes [7][8][9][10][11][12][13][14][15][16][17][18]. Our previous work reported the coloration of silica glass with near-infrared absorbing organic dye [16].…”
