In this work it is proposed a novel antibacterial surface composed of an organicinorganic hybrid matrix of tetraethoxysilane (TEOS) and a weak polyelectrolyte like Poly(acrylic acid sodium salt) (PAA) which are deposited on glass slides by sol-gel method using the dip-coating technique [1]. This work is focused in the in situ synthesis of Ag nanoparticles (NPs) which are responsible of the anti...

In this work a novel antibacterial surface composed of an organic-inorganic hybrid matrix of tetraorthosilicate and a polyelectrolyte is presented. A precursor solution of tetraethoxysilane (TEOS) and poly(acrylic acid sodium salt) (PAA) was prepared and subsequently thin films were fabricated by the dip-coating technique using glass slides as substrates. This hybrid matrix coating is further l...

We report hybrid polymer actuator arrays based on environmentally responsive hydrogel and actuatable optical microstructures that are designed to reversibly switch optical properties in response to the environment. Arrays of micrometer scale plates were patterned by deep reactive ion etching of silicon which served as master structures for replica molding in polydimethylsiloxane (PDMS). UV-cura...

BACKGROUND For implant-supported hybrid prostheses, high mastication forces and reduced acrylic resin thickness over a metal substructure often cause failures arising from tooth or resin fractures. To assay fracture resistance of artificial teeth and resin in implant-supported hybrid prostheses in relation to the titanium structure and retention design supporting teeth. MATERIAL AND METHODS 4...

Increasing usage of polymer composite materials necessitates the development recyclable alternatives to traditional thermoset matrices or new techniques for recycling these materials. One family promising are room temperature infusible acrylic resins, known commercially as Elium®. If be used in tidal stream energy and shipping sectors, they must able withstand long-term immersion seawater witho...
