Silver Chloride – Wool Nanohybrid Materials: Synthesis and Properties

Johnston J.H., Kelly F.M., Victoria University of Wellington, NZ

The development and characterisation of a new nanowool hybrid material formed by functionalising merino wool with silver chloride nanoparticles is presented. The nanoparticles are formed directly on the surface and inside the wool fibre. Initially [...]

Plasmonic Biosensors with biocompatible nanosilver

Sotiriou G.A., Sannomiya T., Teleki A., Voeroes J., Pratsinis S.E., Particle Technology Laboratory, ETH Zürich, CH

In this study, silica-coated nanosilver particles were made by flame aerosol technology. The effect of the silica coating on the morphology of the particles, as well as their biocompatibility was examined. Finally, the potential of [...]

Dielectric Constant, Loss and Breakdown for Ultem containing BaTiO3 Nanoparticles

Lomax E.A., Lomax J.F., Lomax E.A., Lomax J.F., Lu S.C., Calame J.P., Fontanella J.J., Edmondson C.A., Wintersgill M.C., U.S. Naval Academy, US

The need for improved energy storage devices prompts interest in developing new dielectric materials for high energy capacitors. This work reports data on the properties of cast films of BaTiO3 nanoparticles (high dielectric) in the [...]

Synthesis, tuning of electrical conductivity and self-assembly of niobium doped titania nanoparticles

Liu Y., Rathousky J., Bein T., Fattakhova-Rohlfing D., University of Munich (LMU), DE

Controlling the synthesis of ultrasmall, stable oxide nanoparticles of different compositions and functionality is a continuing quest of nanoscience. Here we report on a solvothermal procedure that enables the preparation of crystalline niobium-doped and undoped [...]

Engineered Pigment Nanoparticles: Bottom-up Synthesis, Characterization, and Performance Properties

Carlini R., Makeiff D.A., Allen C.G., Gardner S.J., Paraguay-Delgado F., Malac M., Li P., Xerox Research Centre of Canada, CA

High performance organic nanopigments are an increasingly important class of functional nanomaterials that possess physical properties ranging between molecular and bulk materials. These nanomaterials have been utilized in a variety of important commercial applications including [...]

Synthesis of Nano-Sized Ferrite Materials for H2 Generation from High Temperature Water-Splitting Reaction

Bhosale R., Shende R., Puszynski J., South Dakota School of Mines & Technology, US

As the current research trends in H2 generation using thermochemical water-splitting reaction are focused towards lowering the H2 generation temperatures, it is believed that the nano-sized ferrite materials with porous morphology will significantly reduce the [...]

Re-dispersible ZrO2 powders for transparent high RI nanocomposite

Wang S-H., Sun Y.S., Chiang A.S.T., National Central University, TW

Previous products of nano-ZrO2 usually come in the form of dispersed sol. When they are to be used in organic/inorganic composite, the solvent accompanied may not be compatible with the target polymer system. We have [...]

Rifampicin nanosuspension production using microfluidic device

Schianti J.N., Cerize N.N.P., Oliveira A.M., Derenzo S., Gongora-Rubio M.R., Polytechnic School - University of São Paulo, BR

In this work the results of a study of Rifampicin nanoprecipitation through antisolvent technique are presented, using microfluidic devices. Rifampicin is commonly used in Tuberculosis treatment and presents variability in bioavailability. The particle size and [...]

Nanoscale Plasma Surface Modification of Powders
