Elastomer composites containing layered fillers and hydroxyapatities

Lipinska M., Pietrasik J., Zaborski M., Masek A., Institute of Polymer and Dye Technology, PL

Traditionally, as a filler of rubber carbon black is used. It is an active filler able to reinforce and improve the properties of finished rubber products. For ecological and economic reasons the research activity is [...]

Assessing the Antimicrobial Activity of Silver Nanoparticles Leached from Medical Devices

Casey B.J., Dair B.J., U.S. Food and Drug Administration, US

This work focuses on characterization the leachables released from substrates, e.g. medical devices, containing silver nanoparticles. Furthermore, antimicrobial experiments were conducted to determine how the structure of a silver nanoparticle impact antimicrobial activity. Proper characterization [...]

Investigation of Silica Nanoparticles Accumulated on the Surface of Polymer Nanocomposites Exposed to UV Radiation Using ICP-OES

Rabb S.A., Yu L.L., Bernard C., Nguyen T., NIST, US

Silica nanoparticles are being utilized to enhance the mechanical performance of polymeric materials used in the automotive and construction industries. However, cumulative effects of UV radiation will degrade the polymeric molecules, resulting in a potential [...]

FreeNano – Test Methods for Release of Pigment-Nanoparticles Into the Environment at the End of Life Cycle

Stintz M., TU Dresden, DE

Several coatings with and without nanoscaled additives and pigments were exposed to artificial aging and weathering, before they experienced a mechanical treatment by sanding with process parameters similar to professional sanding condition. The miniature sanding [...]

Critical exponents from parallel plate geometries with periodic and antiperiodic boundary conditions

Silva Jr. J.B., Leite M.M., UFPE, BR

We present a one-particle irreducible formalism to compute critical exponents for a parallel plate geometries for periodic and antiperiodic boundary conditions, at least at two loop order in perturbation theory.

Self-assembly of Nanostructured ZnO-based Homojunction by Two-step Method

Changand Y.Q., Lu Y.D., Guo J.L., Cui X.D., Yang L., Wang Y.W., Long Y., University of Science and Technology of Beijing, CN

In this work, self-assembly of radial nanostructured ZnO homojunction were synthesized by a kind of two-step method. A supplementary growth mechanism is used to explain the formation of nanostructured ZnO homojunction. Photoluminescence (PL) spectra reveals [...]

Fluoropolymer Nanofibers (VDF-TFE 5 mol%) by Electrospinning

Khalfin R., Cohen Y., Technion – Israel Institute of Technology, IL

Poly(vinylidene fluoride) with 5 mol % of tetrafluoroethylene copolymer (VDF-TFE), is known to have the same crystal structure as pure PVDF as well as similar unique electrical properties. The β-phase of this polymers has strong [...]

Integrated phase-Change memory in Bi2Te3 nanowires

Han N.A., Kim S.I., Yang J.D., Lee K., Sohn H., So H-M, Sohn H., Ahn C.W., Yoo K.H., Yonsei University, KR

Bismuth telluride (Bi2Te3) and its alloys are considered to be the best avaiable materials for near room-temperature thermoelectric applications. Moreover, because low-dimensional thermoelectric materials are expected to have a higher figure of merit due to [...]

Fabrication of Structurally Tailored Cobalt Nanowires

Debburman P.K., Kaur D., Pandya D.K., IIT Delhi, IN

we report an interesting observation of effecting structural transition of electrochemically deposited cobalt nanowires with change in aspect ratio of the nanowires. This change can be controlled by the deposition temperature. These nanowires were deposited [...]
