Performance of Critical Flow Venturis under Transient Conditions

April 13, 2010
Author(s)
John D. Wright
Critical flow venturis (CFVs) can be used to measure flow under transient pressure and flow conditions with uncertainties of 0.13 % or less (95 % confidence level). Blow-down tests transferred 630 g of nitrogen during a 100 s interval from an unregulated

Probing Single Nanometer-Scale Pores with Polymeric Molecular Rulers

April 2, 2010
Author(s)
Sarah E. Henrickson, Edmund A. DiMarzio, Qian Wang, Vincent M. Stanford, John J. Kasianowicz
It has been shown that individual molecules of single stranded DNA can be driven electrophoretically through a single Staphylococcus aureus ?-hemolysin ion channel. Polynucleotides thread through the channel as extended chains and the polymer-induced ionic

Sub-50 nm measurements using a 193 nm angle-resolved scatterfield microscope

April 1, 2010
Author(s)
Richard Quintanilha, Martin Y. Sohn, Bryan M. Barnes, Richard M. Silver
Resist-on-silicon sub-50 nm targets have been investigated using a 193 nm angle-resolved scatter field microscope(ARSM). The illumination path of this microscope allows customization of the Conjugate Back Focal Plane (CBFP) while separate collection paths

Flip Chip Lamination Approach to Fabricate Top Metal Contacts on Organic-based Devices

Mariona Coll Bau, Oana Jurchescu, Nadine Gergel-Hackett, Curt A. Richter, Christina Hacker
Flip Chip Lamination approach to fabricate top metal contacts on organic-based devices ; M.Coll, O.D. Jurchescu, N. Gergel-Hackett, C.A. Richter, C,A, Hacker, American Physical Society (APS), March 2010, Portland, OR, USA (oral)

Steady-state and transient photoconductivity in c-axis GaN nanowires grown by nitrogen-plasma-assisted molecular beam epitaxy

February 12, 2010
Author(s)
Norman A. Sanford, Paul T. Blanchard, Kristine A. Bertness, Lorelle Mansfield, John B. Schlager, Aric W. Sanders, Alexana Roshko, Beau Burton, Steven George
Analysis of steady-state and transient photoconductivity measurements at room temperature performed on c-axis oriented GaN nanowires yielded estimates of free carrier concentration, drift, mobility, surface band bending, and surface capture coefficient for

Quantification of the Binding Affinity of a Specific Hydroxyapatite Binding Peptide

January 27, 2010
Author(s)
Michael C. Weiger, Jung Jin Park, Marc D. Roy, Christopher M. Stafford, Alamgir Karim, Matthew L. Becker
The genesis of bone and teeth results from highly coordinated processes which involve several cell types, proteins which direct the nucleation and crystallization of inorganic hydroxyapatite (HA). Recent studies have shown that engineered peptide sequences

Nanoelectronic Fabrication with Flip Chip Lamination

December 15, 2009
Author(s)
Mariona Coll Bau, Curt A. Richter, Christina Hacker
Nanoelectronic fabrication with Flip chip lamination Mariona Coll, CA Richter, CA Hacker, Colloquium Catalan Institute of Nanoscience and Nanotechnology CIN2, Barcelona Spain, Dec 2009.

Thermal Stability of Confined Flip-Chip Laminated w-Functionalized Monolayers

December 3, 2009
Author(s)
Mariona Coll Bau, Curt A. Richter, Christina A. Hacker
We present the results of an IR study of the effect of temperature on the formation of Au-monolayer-Si molecular junctions by using a flip-chip lamination approach. Carboxylic acid-terminated alkanethiols self-assembled on ultrasmooth gold substrate have

NIST Reference Material Scaffolds for Tissue Engineering

December 1, 2009
Author(s)
Carl G. Simon Jr.
The National Institute of Standards and Technology (NIST) has deployed Reference Material (RM) scaffolds for tissue engineering: a series of well-characterized 3D tissue scaffolds with differing porosities (RM 8395, RM 8396 and RM 8397) (Fig. 1). Customers

Electrical Conductivity and Relaxation in Poly(3-hexylthiophene)

November 25, 2009
Author(s)
Jan Obrzut, Kirt A. Page
ABSTRACT: We studied the complex conductivity of regio-regular poly(3-hexylthiophene) (P3HT) in the temperature range between 193K to 333 K (-80 C to 60 C) and in the frequency range from the direct current (DC) to 12 GHz. The identified relaxation process

Electrical Characterization of Soluble Anthradithiophene Derivatives

November 19, 2009
Author(s)
Brad Conrad, Calvin Chan, Marsha A. Loth, John E. Anthony, David J. Gundlach
Organic semiconductors remain an active subject for device physics and material science because of their varied electrical properties and potential for low-cost, high-throughput roll-to-roll processing. Several high-mobility oligomers, such as pentacene
