Introduction/Objective. The objective was to determine the degree of conversion (DC), cross-link density, percentage leachable monomers, flexural strength (FS), and hardness (HV) nanohybrid, nanofilled bulk-fill, giomer, fiber-reinforced, low-shrinkage composites. Methods. Standardized specimens (n = 5/group) Tetric EvoCeram Bulk Fill, Filtek Beautifil, EverX posterior, Kalore, Z250 (microhybri...

background: the purpose of this in vitro study was to evaluate surface discoloration of three microhybrid composite resins (esthet•x hd, clearfi l ap-x, gradia direct) and fi ve nanohybrid composite resins (ceram•x, gc kalore, g-aenial, grandio, grandioso), after staining and bleaching procedures. materials and methods: the composite resins were polymerized with a curing light (celalux ii, voco...

The clinical efficacy of conventional chemotherapeutic agent, methotrexate (MTX), can be limited by its very short plasma half-life, the drug resistance, and the high dosage required for cancer cell suppression. In this study, a new drug delivery system is proposed to overcome such limitations. To realize such a system, MTX was intercalated into layered double hydroxides (LDHs), inorganic drug ...

Gold nanoparticles (Au NPs)@ZnO nanorods (NRs) hybrids, with various molar ratios of ZnO:Au, were developed to enhance generation of reactive oxygen species (ROS) for further application in photodynamic therapy (PDT). By introducing the metal/semiconductor heterostructure interface between Au NPs and ZnO NRs, the electron transfer was modulated under UV irradiation, which dramatically suppresse...

We fabricated a new organic-inorganic hybrid superlattice film using molecular layer deposition [MLD] combined with atomic layer deposition [ALD]. In the molecular layer deposition process, polydiacetylene [PDA] layers were grown by repeated sequential adsorption of titanium tetrachloride and 2,4-hexadiyne-1,6-diol with ultraviolet polymerization under a substrate temperature of 100°C. Titanium...

PURPOSE The aim of this study was to evaluate the effects of 4 mouth rinses on the color stability of two different resin composites. MATERIALS AND METHODS A2 shade sonic-activated bulk fill material SonicFill (Kerr) and conventional nanohybrid composite Filtek Z550 (3M ESPE) were used. Forty disc-shaped specimens (10 mm x 2 mm) were fabricated for both composites and finished using 400-grit ...

We describe a fast and cost-effective process for the growth of carbon nanofibers (CNFs) at a temperature compatible with complementary metal oxide semiconductor technology, using highly stable polymer-Pd nanohybrid colloidal solutions of palladium catalyst nanoparticles (NPs). Two polymer-Pd nanohybrids, namely poly(lauryl methacrylate)-block-poly((2-acetoacetoxy)ethyl methacrylate)/Pd (LauMA ...
