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, [...]

Controlling the Size and Morphology of Silver Nanoparticles: Role of Chemical Routes

Ahmad T., Jamia Millia Islamia (Central University), IN

The preparation of nanoparticles with well defined size and morphology is an important challenge for various industrial applications. Silver nanoparticles with controlled size and morphology have been prepared successfully through various chemical routes (Inverse microemulsions, [...]

Green and Continuous Hydrothermal Synthesis of Nanophosphors for Biomedical Applications

Gruar R., Kellici S., Tighe C., Darr J., UCL, UK

The luminescent properties of Y2O3:Eu have attracted considerable research interest due to the emission and chemical stability of the oxide phosphor. Subsequently, we evaluated the calcination of YOOH:Eu (4% dopant) synthesised directly in a continuous [...]

Synthesis of nanocrystalline nitrate enclathrated zeolite with intermediate framework structure between sodalite (SOD) and cancrinite (CAN)

Buhl J.-Ch., Cramm S., Leibniz University Hannover, DE

Synthesis of nitrate enclathrated nanocrystalline aluminosilicate zeolite was performed in the system Na2O-SiO2-Al2O3-H20-NaNO3-(TEA) under superalkaline low temperature conditions at 333 K. Formation of nanoparticles occurred already after 3 hours with sizes not exceeding 50 nm [...]
