Silanization has emerged in recent years as a way to obtain a stronger and more stable attachment of biomolecules to metallic substrates. However, its impact on protein conformation, a key aspect that influences cell response, has hardly been studied. In this work, we analyzed by atomic force microscopy (AFM) the distribution and conformation of type I collagen on plasma-treated surfaces before...

OBJECTIVES This study evaluated the effect of three different surface conditioning methods on the bond strength of a Bis-GMA based luting cement to six commercial dental ceramics. METHODS Six disc shaped ceramic specimens (glass ceramics, glass infiltrated alumina, glass infiltrated zirconium dioxide reinforced alumina) were used for each test group yielding a total number of 216 specimens. T...

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...

Cellulosic insulating paper is the essential component of insulation in power transformers. Under thermal stress inside transformer, cellulosic degrades and generates formic acid. Meanwhile, presence acid further accelerates aging process paper. This study takes cellulose molecule composed D-glucose as research object. The ReaxFF reactive force field applied to simulate high-temperature During ...
