Nanotechnology and the Global Poor: United States Policy and International Collaborations

Rodrigues R., Sandler R., Kay W.D., Lodwick T., Northeastern University, US

Nanotechnology and nanomanufacturing have tremendous potential for benefiting the global poor—the approximately 2.7 billion people in the world that live on less that 2 dollars per day (purchasing power parity). For example, nanotechnologies may help [...]

Nanotechnology – Disruptive Technologies for Electric Utility Systems. Challenges and Opportunities

Stringer J., Richman R.H., Izambard, US

Within the next 25 years, the electric power utility system in the U.S. will face a number of serious challenges. These will include issues related to diminishing supplies and increasing costs of fossil fuels, the [...]

An integrated NMR/nanosensor system for sensitive detection of environmental toxins and harmful microbes

Perez J.M., Fries D.P., Hickman J.J., University of Central Florida, US

The use of nanoparticles and NMR detection technologies has lead to significant improvements in sensitivity. Nanoparticles have many useful optical and electronic properties derived from their small size. When coupled to affinity ligands, these materials [...]

Nano-Hetero Structure for direct energy conversion

Popa-Simil L., LAVM, Inc., US

The direct conversion of nuclear energy becomes possible in hetero-nanostructures. To convert the kinetic energy of the fission product into electricity it has to be created a nanostructure formed from a repetitive conductor-insulator structure generically [...]

Aided Transport of Nano-Iron in Clay Soils Using Direct Electric Field

Hannum L., Pamukcu S., Lehigh University, US

The influence of direct current electric fields on the possible electrokinetic delivery of a nano-iron slurry in clay for the purpose of fast and effective remediation of soil contaminants has been tested. Nano-iron can be [...]

An investigation of natural nanoparticles for cleaning applications

Nero M., Tran B., Naturell Clean, Inc., US

Bioremediant cleaning products are investigated for every day use by consumers in their homes. Nano-components such as biosurfactants, enzymes, metaloenzymes, and chelating agents are derived from Sea Kelp and are the result of naturally occurring [...]

Manufacturable nanoscale membranes – material development and biological separations

Gaborski T.R., Striemer C.C., Snyder J.L., Fang D.Z., Fauchet P.M., McGrath J.L., University of Rochester, US

We have developed a new class of ultrathin porous nanocrystalline silicon (pnc-Si) membranes using inexpensive and scalable silicon fabrication techniques. Pnc-Si is formed from a deposited amorphous silicon thin film, where nanoscale pores are introduced [...]

Low Temperature Nanolayers of Metal Oxides By MVD

Kobrin B., Dangaria N., Chinn J., Applied Microstructures, Inc., US

Molecular Vapor Deposition (MVDTM) techniques and equipment have been successfully used for many coating applications in the MEMS, disk drive, and nano-imprint lithography fields. By exploiting the ability of MVD to deposit an in-situ metal [...]

Utilizing PRINTTM Technology to Create Precision Nanopatterned Films

Denison Rothrock G., Rolland J., Henn R., Liquidia Technologies, US

We describe the use of a new, enabling class of materials for performing precise, nano-scale imprint lithography for patterned film replication. These low surface energy, minimally adhesive, room-temperature photocurable perfluoropolyether (PFPE) elastomers, trademarked as Liquidia’s [...]

Single Election Trapping in Nanoscale Transistors; RTS(Random Telegraph Signals) and l/f Noise

Forbes L., Miller D.A., Louie M.Y., Oregon State University, US

Random telegraph signal, RTS, noise[1] is most obvious in submicron devices with traps, for example in nanoscale MOS transistors, MOSFET’s, with a low number of carriers. RTS is sometimes an indicator of poor device quality [...]
