[reaction: see text] Treatment of hydroxy-substituted silyl epoxides with Grignard reagents induces a 1,2-carbon shift to reveal alpha-silyl aldehydes, which are trapped by highly diastereoselective addition reactions of the Grignard reagent. The starting epoxides are readily accessible from propargylic alcohols by regio- and diastereoselective hydrosilylation and epoxidation reactions. In addi...

A silane-based adhesive formulation, used in the aerospace industry, was studied using sub-nanometre spatially-resolved energy loss spectroscopy, as a function of the concentration of silane used in the adhesive. The changes in the relative oxygen concentration and the occupancy of p-type states in the oxygen density of states reveal the existence of a composite layer between the aluminium and ...

This paper is to study the effect of surface coating and silane hydrophobic agents for high performance concrete durability in a marine environment of tidal zone and splash zone by exposure test in JiaoZhou Bay. The results indicated that surface coating had good protection and coating quality after a 5-year period and the adhesive strength with concrete surface was more than 2.5 MPa. Surface c...

objective: repair of an indirect restoration is usually preferred over its replacement. this study aimed to evaluate the effect of silane in different surface preparation techniques on the bond strength of direct to indirect composite resin.   methods: for this in vitro experimental study, 48 indirect composite cubes were fabricated, divided into 4 groups of 12 and subjected to the following pr...

Microcrystalline silicon solar cells with AM 1.5 conversion efficiency above 5 % have been deposited at deposition rates in excess of 10 Å/s. This is achieved by VHF-GD at an excitation frequency of 130 MHz. By increasing the plasma power at a dilution ratio of 7.5 % silane/(silane+hydrogen) there first appears a morphological transition from a-Si:H to μc-Si:H and then an increase in deposition...

By the introduction of an organic silane self-assembled monolayer, an interface-engineering approach is demonstrated for hole-conductor-free, fully printable mesoscopic perovskite solar cells based on a carbon counter electrode. The self-assembled silane monolayer is incorporated between the TiO2 and CH3NH3PbI3, resulting in optimized interface band alignments and enhanced charge lifetime. The ...
