Application of zinc and magnesium oxides nanoparticles in crosslinking of carboxylated butadiene-acrylonitrile rubber

Lipinska M., Zaborski M., Technical University of Lodz, PL

The aim of this work was to study the activity of several nanosized zinc and magnesium oxides in the crosslinking of carboxylated nitrile elastomer XNBR. The influence of the specific surface area, particle size and [...]

Bimodal size distributed silver nanoparticles on copper substrate: in situ heat treating under air and protective atmospheres

Sopousek J., Bursik J., Zalesak J., Pesina Z., Masaryk University, CZ

Ag nano-suspension was prepared by a wet synthetic route. The liquid phase consisted of an organic solvent and the particles had a bimodal distribution with a very narrow size distribution (compare Figure 1). The surface [...]

Synthesis, Characterization and Sampling of GaP Nanoparticles for Light Emissive Devices

Pyshkin S.L., Ballato J., Belevschii S., Rusu E., Racu A., Van DerVeer D., Academy of Sciences of Moldova, MD

This work reviews our recent efforts to advance quality of GaP nanoparticles in framework of the current US/Italy/France/Romania/Moldova project sponsored by the US Government. These quality GaP nanoparticles were synthesized for application in advanced light [...]

Tuning the Gas Pressure Discharge of Nanoenergetic materials by Boron and Carbon Nanotube Additives

Martirosyan K.S., Wang L., Luss D., University of Texas at Brownsville, US

Thermite reactions are highly exothermic and may rapidly release high amount of stored chemical energy in the form of heat, light and wave. Nanothermite formulations that use aluminum or magnesium as the reducing agent and [...]

Novel optical property of Ag@PPy nanoparticles

Ye S., Chen S., Lu Y., Nanjing University, CN

we reported the characterization of the luminescenct properties of Ag@PPy nanoparticles, provided an explanation for the observed spectral shift in terms of the energy levels and exploited the Ag@PPy nanoparticles with doping-dependent emission peak shift [...]

The morphology and properties of silica nanoparticles synthesized by sol-gel reaction in elastomer matrix

Lipinska M., Zaborski M., Technical University of Lodz, PL

In our studies the influence of different dispersing agents on the synthesis and character of silica particles prepared by a sol-gel reaction was investigated. The silica with different surface morphology was synthesized from tetraethoxysilane (TEOS) [...]

One Pot vs Two Steps Synthesis of Fluorescent Gold Nanoparticles and Capping with Thiolated Organic Linker

Rastogi S.K., Denn B.D., Branen A.L., University of Idaho, US

Nobel metal nanoparticles (NPs) such as Au and Ag have gained great attention in the past decades due to their fundamental optical properties. Based on that interest, the current work is focused for the synthesis [...]

Characterization of Catalyst Effect on Carbon Nanopearls

Pacley S., Theodore M., Air Force Research Laboratory, US

This presentation focuses on the effect of the Ni catalyst size on the structure of carbon nanopearls (or carbon spheres). Carbon nanopearls are known to have electronic properties, which make them ideal for cold cathode [...]

Simple, open air method to synthesize monodisperse and size selective PbSe quantum dots

Pan Y., Lombardi J., City College of New York, US

Simple, open air method to synthesize monodisperse and size selective PbSe quantum dots is reported here. PbCl2 complexed with oleylamine was used as the lead precursor. Se powder dissolved in 1-octadecene was used as the [...]

Electrical conductivity studies of nanocrystalline Dy3+ doped BaMoO4, synthesised by sol-gel process

Jena P., Nallamuthu N., Venkateswarlu M., Satyanarayana N., Pondicherry University, IN

Solid oxide fuel cells (SOFCs) have attracted great attention in electrochemical devices because of their high energy conversion efficiency, little pollution and widely flexible fuel choices. Scheelite type based oxide ion conducting materials like PbWO4, [...]
