Effects of porosity on dynamic indentation resistance of silica nanofoam. [PDF]
, 2017 The dynamic indentation behaviors of monolithic silica nanofoams of various porosities are investigated. When the pore size is on the nm scale, as the porosity increases, despite the decrease in mass density, the resistance offered by silica nanofoam to ...

Effect of Chemical Composition on Microstructure and Hydrophobic Properties of SiO2-TiO2@PDMS Coating [PDF]
Iranian Journal of Materials Science and Engineering, 2023 We report a simple and practical approach for the easy production of superhydrophobic coatings based on TiO2-SiO2@PDMS. In this study, we used tetraethylorthosilicate (TEOS) and titanium tetraisopropoxide (TTIP) as a precursor for the sol-gel synthesis ...

Silaffins in Silica Biomineralization and Biomimetic Silica Precipitation [PDF]
Marine Drugs, 2015 Biomineralization processes leading to complex solid structures of inorganic material in biological systems are constantly gaining attention in biotechnology and biomedical research. An outstanding example for biomineral morphogenesis is the formation of highly elaborate, nano-patterned silica shells by diatoms.
