Silylboronate-Mediated Defluorosilylation of Aryl Fluorides with or without Ni-Catalyst
Frontiers in Chemistry, 2021 The defluorosilylation of aryl fluorides to access aryl silanes was achieved under transition-metal-free conditions via an inert C–F bond activation. The defluorosilylation, mediated by silylboronates and KOtBu, proceeded smoothly at room temperature to ...

The preparation and characterisation of monomeric and linked metal carbonyl clusters containing the closo-Si2Co4 pseudo-octahedral core [PDF]
, 2002 PhSiH3 reacts with [Co₄(CO)₁₂] at 50 °C in hydrocarbon solvents to give [(µ₄-SiPh)₂Co₄(CO)₁₁], 2c, shown by an X-ray crystal structure determination to have a pseudo-octahedral Si₂Co₄ core. Substituted aryl-silanes behaved similarly.

Functionalization of arrays of silica nanochannels by post-condensation [PDF]
, 2016 Functionalized arrays of silica nanochannels (ASNCs) were prepared by post-condensation of amino-functional alkoxysilanes (NH-silanes). The method of post-condensation combines postsynthetic grafting and co-condensation – the classical pathways for the ...

Iron Sequestration by Galloyl–Silane Nano Coatings Inhibits Biofilm Formation of Sulfitobacter sp.
Biomimetics, 2023 Microbially-induced corrosion is the acceleration of corrosion induced by bacterial biofilms. The bacteria in the biofilms oxidize metals on the surface, especially evident with iron, to drive metabolic activity and reduce inorganic species such as ...

Different bonding agents effect on adhesive bond strength: lithium disilicate glass ceramic
Revista de Odontologia da UNESP, 2020 Introduction The silanization of the ceramic surface prior to applying the adhesive and/or resinous materials plays an important role in bond strength. Nowadays, a new family of adhesive systems has been introduced into the market, aiming to simplify the
