91. Global View of International Standards and Measurements: Challenges and Concerns for Nanotechnologies
Topic: Nanotechnology
Published: 8/30/2010
Author: Herbert S Bennett
Abstract: We first discuss why international standards are important for nanomanufacturing and business models. The scopes and structures of the International Electrotechnical Commission Technical Committee 113 (IEC TC 113) on nano-electrotechnologies and the ...

92. Monodisperse Gold-Copper bimetallic Nanocubes: Facile One-Step Synthesis with Controllable Sizes and Compositions
Topic: Nanotechnology
Published: 8/16/2010
Authors: Yonglin Liu, Angela R Hight Walker
Abstract: We demonstrate a one-pot polyol strategy for the synthesis of Au - Cu perfect nanocubes. To the best of the authors knowledge, this represents the first-time production of Au - Cu bimetallic nanocubes. By carefully adjusting the reaction parameter ...

93. Synthetic Approach for Tunable, Size-Selective Formation of Monodisperse, Diphosphine-Protected Gold Nanoclusters
Topic: Nanotechnology
Published: 8/10/2010
Authors: John M. Pettibone, Jeffrey W Hudgens
Abstract: Most nanoparticle syntheses, including those based on the Brust-Schiffrin method, produce a mixture of different metal core sizes. This report presents a new strategy for controlling the size and dispersity of ultra-small nanoclusters through select ...

94. Production and Characterization of Polymer Microspheres Containing Trace Explosives Using Precision Particle Fabrication Technology
Report Number: 902104
Topic: Nanotechnology
Published: 8/2/2010
Authors: Matthew E Staymates, Robert A Fletcher, Jessica L Staymates, John G Gillen, Cory Berkland
Abstract: Well characterized test materials are essential for validating the performance of current trace explosive detection systems. These test materials must replicate trace explosive contamination in the form of small particles with characteristic diameter ...

95. Nanoparticle Separation and Metrology by Three-Dimensional Nanofluidic Size Exclusion
Topic: Nanotechnology
Published: 8/1/2010
Authors: Samuel M Stavis, Jon C Geist, Michael Gaitan

96. Thermally-Reversible Surface Morphology Transition Between Cylinders and Spheres in Thin Diblock Copolymer Films
Topic: Nanotechnology
Published: 7/28/2010
Authors: Xiaohua Zhang, Kevin G. Yager, Jack F Douglas
Abstract: Many phase transitions exhibit ordering transitions at the boundary of the material that are distinct from the interior where the intermolecular interactions can be significantly different. The present result considers the existence of a reversible s ...

97. Controlled nucleation of GaN nanowires grown with molecular beam epitaxy
Topic: Nanotechnology
Published: 7/13/2010
Authors: Kristine A Bertness, Aric Warner Sanders, Devin M. Rourke, Todd E Harvey, Alexana Roshko, Norman A Sanford
Abstract: The location of GaN nanowires was controlled with essentially perfect selectivity using patterned SiNx prior to molecular beam epitaxy growth. Growth was uniform within mask openings and absent on the mask surface for over 95 % of the usable area of ...

98. Passive terahertz camera for standoff security screening
Topic: Nanotechnology
Published: 7/1/2010
Authors: Erich N Grossman, Charles Dietlein
Abstract: We describe the construction and performance of a passive, real-time terahertz camera based on a modular, 64-element linear array of cryogenic hotspot microbolometers. A reflective conical scanner sweeps out a 2 m ×4 m(vertical × horizontal) field of ...
