Synthesis and Synterability of Hydroxyapatite-Coated Zirconia Nanopowders

Bondioli F., Cannillo V., Ferrari A.M., Manfredini T., Università di Modena e Reggio Emilia, IT

Hydroxyapatite (HAP), Ca10(PO4)6(OH)2, is a well-known and a valuable implant material with biocompatibility and bioactive properties. Full utilisation of the unique properties of hydroxyapatite bulk ceramics is, however, possible only after its proper reinforcement, i.e. [...]

Ultra-thin Nanocomposite Membranes for Highly Sensitive Sensors

Kang T.J., Jang E.Y., Lee J-H., Kim Y.H., Seoul National University, KR

Highly sensitive sensor arrays are critical for prospective devices and demanded for various applications. Measuring microscopic deflections with sensitive membranes is one of the most versatile approaches for pressure, acoustic, chemical and biomolecular sensing. Here [...]

Nanocomposites for Restorative Dentistry

Uveges A., Bukovinszki K., Szaloki M., Hegedus C., Borbely J., University of Debrecen, HU

Dental filling materials are crosslinked resins with high abrasion resistance. Inorganic micro and recently nanofillers are introduced to improve their properties. However, the shrinkage of the resin component during the polymerization reaction is still a [...]

Favored Osteoblast Interactions with Aerosol Printed 3D Nano-to-Macro Hierarchical Architectures: The Promise of Nanocomposites as Orthopedic Prostheses

Liu H., Webster T.J., Brown University, US

Ceramic/polymer nanocomposites simulate bone in terms of its nanostructure and associated properties, thus, offering a promising new opportunity for bone regeneration in a natural way. Previous in vitro studies demonstrated that well-dispersed nanophase titania in [...]

Cytotoxicity of Dental Nanocomposite Particles

Kostoryz E.L., Utter C.J., Wang Y., Dusevich V., Spencer P., University of Missouri-Kansas City, US

Safety assessment of dental composites is focused on the toxicity of leachable unreacted monomers. With the advent of nanostructured materials, safety assessment needs to include the potential toxicity of nanoparticles. The objective of this study [...]

Synthesis of a nano electro-magnetic polymer and its application in a DCT biosensor

Pal S., Hummel E.B., Alocilja E.C., Michigan State University, US

This experimental study was focused on the development of a nanomagnetic conductive polymer and its application in a direct-charge transfer biosensor (Figure1) for the detection of Bacillus species. A polyaniline-γFe2O3 nanocomposite transducer was first synthesized [...]

Efects of silver nanoparticle on the physical properties of syndiotactic polypropylene

Kang E.C., Kim B.C., Hanyang University, KR

The effects of silver nanoparticle on the physical properties of syndiotactic polypropylene (sPP) were investigated in terms of rheological responses and crystallization behavior under shear. Silver nanoparticle played as the nucleating agent of sPP by [...]

Properties of Paraffin Wax/Montmorillonite Nanocomposite Coatings

Pu G., Wang J., Severtson S.J., University of Minnesota, US

Results are reviewed from a study aimed at enhancing the performance of paraffin wax based materials for barrier coating applications. Nanocomposites prepared by ultrasonic processing from paraffin wax matrices and reinforced with organically modified montmorillonite [...]

The Effect of POSS Compatibility on the Morphology of Thiol-ene Polymer Nanocomposites

Clark T., Hoyle C., Nazerenko S., University of Southern Mississippi, US

The physical properties of thiol-ene/POSS nanocomposites are measured and used to indicate the morphological changes of the materials as a function of POSS concentrations. Vinyl POSS monomers are modified with various organic pendants using an [...]

Conducting Polymer Nanocomposites: The Role of the Electronic Fingerprint of Carbon Nanotubes

Chiu P.L., Ma Y., Serrano A., Wang L., Mendelsohn R., He H., Rutgers University, US

In this presentation, we report that dispersion and functionalization of single-walled carbon nanotubes (SWNTs) with different dispersing methods and dispersing agents result different SWNTs with different electronic structures and surface chemistries. In-situ polymerization of the [...]
