Porosity control of alkali-activated aluminosilicates via functional alkoxysilane additives
… slurry was found to be miscible with various alkoxysilanes, and the resulting cured geopolymer strongly adhered to organic polymers if and only if the alkoxysilane possessed an appropriate coupling agent linking group for the polymer. Issues relating to maximizing reactivity and properly …

Evidence of Student Learning of Spectrophotometry and Intermolecular Forces in the Chemistry Laboratory
… droplets on glass slides that were modified with alkoxysilanes. The lab engages students in constructing explanations that bridge macroscopic observations and submicroscopic representations, promoting causal reasoning grounded in molecular structure and surface chemistry. This laboratory …

A DIGITAL DATA ACQUISITION SYSTEM FOR INELASTIC ELECTRON TUNNELLING SPECTROSCOPY
… or adlayer structure is indicated in the case of alkoxysilanes, but several possibilities are discussed.

Molecular Crosslinking of Calcium-Silicate-Hydrate with Organosilanes: Toward Engineering of Cementitious Matrices with High Thermal Resistance
… realized via sol-gel processing and using bis-alkoxysilanes of various lengths of the alkyl chain. The results of the extensive experimental campaign show that the novel organic-inorganic gels have layered turbostratic molecular structure with certain similarities to C-S-H precipitating in …

Polymeric capsules for self-healing anticorrosion coatings
… corrosion inhibitors were synthesized. Thus, alkoxysilanes possessing long hydrophobic tail, combining passivating and water-repelling properties, were encapsulated in polyurethane shell. The mechanism of action of the active material required core-shell morphology of the capsules. The new …

Raman-Spektroskopie hybridpolymerer Sol-Gel-Materialien : vom Sol bis zur Schicht
In der vorliegenden Arbeit wurden durch den Sol-Gel-Prozeß hergestellte hybride Sole, Xerogele und Schichten mit Hilfe der Raman-Spektroskopie untersucht. Dazu wurden zunächst die schwingungsspektroskopischen Zuordnungen für verschiedene Alkoxysilanen ergänzt und zusammengefasst. Anschließend wurde …

Growth and chemical functionalization of SiC nanowires for biomedical applications in cardiology and oncology
… silane (Si-NCS). These alkoxysilanes react with the silica surface and covalently bind to the NWs. Thus, it was possible introduce on the NWs surface amino or isothiocyanate groups, able to react with proper TSCs in the anchoring step. To conjugate the NWs with TSCs, it …
