We measure silane density and Sulfo-EMCS cross-linker coupling efficiency on aminosilane films by high-resolution X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM) measurements. We then characterize DNA immobilization and hybridization on these films by (32)P-radiometry. We find that the silane film structure controls the efficiency of the subsequent steps toward DNA hybr...

Basalt fibre composite materials have shown good application prospects in electrical equipment, but their reliability can be affected by damp-heat ageing. In this work, the interface, mechanical, and properties of basalt composites treated with three coupling agents via ageing were compared. Molecular simulations conducted to reveal mechanism composites. The results show that γ-aminopropyl trie...

fiber post (GFP) treated or not with phosphoric acid, silane coupling agent, and unfilled resin. GFPs were etched or not with 37% phosphoric acid and different surface coating applied: silane coupling agent, unfilled resin, or both. Composite resin blocks were built around a 4-mm height on the GFP. Unfilled resin (20 s) and composite resin (40 s) were light activated by a light-emitting diode u...

Timo Heikkinen. Bonding of Composite Resin to Alumina and Zirconia Ceramics with Special Emphasis on Surface Conditioning and Use of Coupling Agents. Department of Biomaterials Science, Institute of Dentistry, University of Turku. Annales Universitatis Turkuensis, Turku, Finland 2011. Dental oxide ceramics have been inspired by their biocompability and mechanical properties which have made dura...

Arsenic (As) contamination in groundwater is a great environmental health concern and is often the result of contact between groundwater and arsenic-containing rocks or sediments and from variation of pH and redox potentials in the subsurface. In the past decade, magnetite nanoparticles (MNPs) have been shown to have high adsorption activity towards As. Alerted by the reported cytotoxicity of 5...

Recently, there have been many materials used for denture base such as polymethyl methacrylate (PMMA) resin, modifi ed PMMA resin and nylon1,2). The material most often used to fabricate denture base and denture teeth was PMMA resin. PMMA is the most commonly used material due to its good mechanical and physical properties, compatibility with oral tissue, aesthetics, ease of repair and low cost...
