Synthesis of Perylenediimide-Functionalized Silsesquioxane Nanostructures
… by the substitution reaction and the modified Stöber method. The PDI-dimethylethoxy silane precursor was produced in high yield by substituting 3-aminopropyldimethylethoxysilane on perylene-3,4,9,10-tetracarboxylicdianhydride as side chains. The optically active PDI-dimethyl nanoribbons were …

Novel Rubber Nanocomposites with Adaptable Mechanical Properties
… without surfactants via two different methods: the modified Stöber method and the original Stöber method. The former method unfortunately gave silica particle with unsatisfactory particle size and size distribution, which did not meet our requirement since it brought about unnecessary …

Coating and Doping of Ge QDs
… these particles was successful using a modified Stöber method. Monodispersed silica nanoparticles 20 nm in diameter were synthesized with Ge QDs as seeds. The resulting structures comprise of Ge QD core within a silica sphere. Films of these particles result in an average QD…QD distance of 9.6 …

Performance assessment of Au SERS substrates prepared by deposition of Au nanoparticles on screen-printed SiO2 particle films
… Screen-printing, a low-cost fabrication method, has been proposed as a reproducible and affordable approach for the preparation of 3D SERS-active substrates. In this work, a new solution-based film fabrication method is proposed for the preparation of Au@SiO2 3D SERS-active substrates. …

Magnetic polyamide 6 nanocomposites for increasing damage tolerance through self-healing of composite structures.
… two functionalisation techniques - viz. silica (Stöber method for lower silica loading and tri-phasic reverse emulsion method for higher silica loading), and oleic acid (22%, 33%, 44%, and 55% w/w of nanoparticles) variations - were experimentally investigated as capable of changing hydrophobic …
