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 [...]

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 [...]

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 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 [...]

Production of High Surface Area Oxygen Sensitive Powders by Na Flame Synthesis

Mann L., Cabot Corporation, US

Cabot Corporation is developing a new particle generation platform that is ideally suited for the production of oxygen sensitive nano-scale powders. The Na Flame Synthesis process is based on the hypergolic vapor phase reaction between [...]

Rapid Determination of Purity of Carbon Nanotubes

Wall M., Hodkiewicz J., Thermo Fisher Scientific, US

Raman spectroscopy can provide for quick measurements of the carbonaceous purity of carbon nanotube samples. Carbonaceous purity is a critical parameter for many applications of carbon nanotubes. Raman spectroscopy has been reported many times in [...]

Improved Nanoreinforced Composite Material Bonds with Potential Sensing Capabilities

Starikov D., Price A., Glenn T., Attia F., Fischer M., Bokadoum M., Bensaoula A., Integrated Micro Sensors Inc., US

Dramatic increase in the bond strength of composite/adhesive interfaces of nano reinforced composite material joints and structures has been achieved using laser-assisted fabrication of Micro Column Arrays (MCA) on the surface of the two materials [...]

Tearing Graphene

Moura M.J.B., Marder M., University of Texas at Austin, US

Experiments on free standing graphene can expose the graphene sheets to out-of-plane forces. An example of that is the back-gate voltage experimental setup. Here we show that out-of-plane forces can cause free standing graphene to [...]
