This work evaluates the efficiency of silanization and phosphonation reactions for grafting alkyl chains on surface titanium treated by nanosecond laser. The light blue squama-like oxide layers with dominating anatase rutile were obtained. using alkoxysilanes C12 C18 was attempted in tetrahydrofuran, pure liquid phase vapor phase. octylphosphonic acid performed boiling water solutions. obtained...

Photoinitiated silane-ene chemistry has the potential to pave the way toward spatially resolved organosilicon compounds, which might find application in biomedicine, microelectronics, and other advanced fields. Moreover, this approach could serve as a viable alternative to the popular photoinitiated thiol-ene chemistry, which gives access to defined and functional photopolymer networks. A difun...

Silane coupling agents have been frequently used as interfacial agents in polymer composites to improve interfacial strength and resistance to fluid migration. Although the capability of these agents in improving properties and performance of composites has been reported, there are still many uncertainties regarding the processing-structure-property relationships and the mechanisms of coupling ...

A "grafting from" approach has been used for controlled deposition of cross-linked polymers by living radical polymerisation. Borosilicate glass was modified with N,N-diethylaminodithiocarbamoylpropyl(trimethoxy)silane, in order to confine the iniferter reactive groups solely at its surface, then placed in solution with monomers and cross-linker. The polymerisation was initiated by UV irradiati...

An affinity media for endotoxin removal based on silica gel was prepared by activation with silane coupling agent and subsequent conjugation with histidine (His) as a ligand. The influence of pore size and particle dimension of the silica gel and the grafting conditions such as reaction temperature and concentration of His in solution on the grafting yield of His were studied by means of IR, th...

This study evaluated the effect of air drying temperature and different silane coupling agents on the bond strength between glass fiber posts and composite resin core. The post surface was cleaned with alcohol and treated with different silane coupling agents, being three prehydrolyzed silanes [Silano (Angelus), Prosil (FGM), RelyX Ceramic Primer (3M ESPE)] and one two-component silane [Silane ...

This paper describes a novel approach of forming micropatterned co-cultures using a combination of oxygen plasma ashing and electrochemical removal of poly(ethylene glycol) (PEG) silane from indium tin oxide (ITO) substrates. After assembling a layer of PEG silane on ITO, photolithography and oxygen plasma cleaning were used to form cell-adhesive domains within the non-fouling PEG silane layer....

In the context of rare earth element extraction using solid-liquid process, hybrid materials having specific functional group were largely studied. However, there is a lack in situ characterization method to understand how behaves when interacts with element. Here, we propose new experimental interaction between immobilized and REE aqueous media well-characterized model system coupled surface a...

Objectives: Ceramics have advantages such as optimal esthetics and biocompatibility. However, in the oral environment, they are subjected to high levels of stress due to masticatory forces, saliva, thermal changes and alterations of pH, which increase their risk of fracture. Since replacement of these restorations is costly and time-consuming, composite resin is often used for intraoral repair ...
