Electronic transport in two dimensional graphene

May 16, 2011
Author(s)
Shaffique Adam, Sankar Das Sarma, Euyheon Hwang, Enrico Rossi
We provide a broad review of fundamental electronic properties of two-dimensional graphene with the emphasis on density and temperature dependent carrier transport in doped or gated graphene structures. A salient feature of our review is a critical

EXPOSING GLAZING ASSEMBLIES TO FIREBRAND SHOWERS

May 16, 2011
Author(s)
Samuel L. Manzello, Sayaka S. Suzuki, Yoshihiko Hayashi
An experimental campaign was undertaken to determine vulnerabilities of glazing assemblies to firebrand bombardment using the NIST Dragon installed in the Building Research Institute’s Fire Research Wind Tunnel Facility (FRWTF). Results of these

Fabrication, characterization and simulation of high performance Si nanowire-based non-volatile memory cells

May 16, 2011
Author(s)
Xiaoxiao Zhu, Qiliang Li, D. E. Ioannou, Xuelei X. Liang, Diefeng Gu, Helmut Baumgart, John E. Bonevich, John S. Suehle, Curt A. Richter
We report the fabrication, characterization and simulation of Si nanowire SONOS-like non- volatile memory with HfO2 charge trapping layers of varying thicknesses. The memory cells, which are fabricated by self-aligning in situ grown Si nanowires, exhibit

Mechanics behind 4-D interferometric measurement of biofilm mediated tooth decay

May 16, 2011
Author(s)
Michael S. Waters, Bin (. Yang, Nancy J. Lin, Sheng Lin-Gibson
Evaluating the efficacy of dental materials to protect human teeth requires the capacity to measure tooth accurately and precisely decay. Current practices for determining tooth decay are destructive, qualitative to lowly quantitative, and/or measure bulk

Spatial dependence of output pulse delay in a niobium nitride nanowire superconducting single-photon detector

May 16, 2011
Author(s)
Sae Woo Nam, J. A. O'Connor, Michael Tanner, C. M. Natarajan, G. S. Buller, R. J. Warburton, S Miki, Z. Wang, Robert Hadfield
We report on the position-dependent variation in output pulse timing across a superconducting single- photon detector. Our device consists of a single niobium nitride nanowire meander (100 nm width, 4 nm film thickness, 2 mm length). We use a confocal

Tumor volume measurement errors RECIST studied with realistic tumor models

May 16, 2011
Author(s)
Benjamin R. Galloway, Adele Peskin, Zachary H. Levine
RECIST (Response Evaluation Criteria in Solid Tumors) is a linear measure intended to predict tumor volume in medical computed tomography (CT). In this work, using purely geometrical considerations, we estimate how well RECIST can predict the volume of

Usability and Accessibility in Consumer Health Informatics: Current Trends and Future Challenges

May 16, 2011
Author(s)
Larry Goldberg, Bettijoyce B. Lide, Svetlana Z. Lowry, Holly Massett, Whitney Quesenbery, Ben Schneiderman
People arrive at health applications with expectations from the rest of their lives and those expectations are rapidly rising. Beyond basic access to their own health records and to their healthcare providers, consumers expect their health information to

Bottlenose Dolphins as Indicators of Persistent Organic Pollutants in Waters Along the US East and Gulf of Mexico Coasts

May 15, 2011
Author(s)
John R. Kucklick, Lori Schwacke, Randall S. Wells, Aleta Hohn, Aurore Guichard, Jennifer Yordy, Larry Hansen, Eric Zolman, Rachel Wilson, J. L. Litz, Doug Nowacek, Teresa Rowles, Rebecca S. Pugh, Brian C. Balmer, Carrie Sinclair, Patricia Rosel
Persistent organic pollutants (POPs) including legacy POPs (PCBs, chlordanes, mirex, DDTs, HCB, and dieldrin) and polybrominated diphenyl ether (PBDE) flame retardants were determined in 300 blubber biopsy samples from coastal and near shore/estuarine male

Electromigration of Cu Interconnects Under AC and DC Test Conditions

May 15, 2011
Author(s)
Robert R. Keller, David T. Read, Roey Shaviv, Greg Harm, Sangita Kumari
Electromigration of a 65 nm technology generation test vehicle was measured using DC, AC followed by DC, and three rectangular wave DC stressing conditions at 598 K. In some of the experiments samples were allowed to cool to room temperature between stress

MSEL Sustainability Seminar Series (2009)

May 15, 2011
Author(s)
Winnie K. Wong-Ng, Kathryn L. Beers, Richard E. Ricker, Martin L. Green
An MSEL Sustainability Seminar Series took place in 2009, aimed at the following goals: (1) to introduce this important subject matter to our staff and (2) to learn and discuss the metrology needs for materials for sustainability applications. Since

Reproducibility and Robustness of a Real-Time Microfluidic Cell Toxicity Assay

May 15, 2011
Author(s)
Gregory A. Cooksey, John T. Elliott, Anne L. Plant
Numerous opportunities exist to apply microfluidic technology to high-throughput and high-content cell-based assays. However, maximizing the value of these assays for drug discovery, screening or toxicity evaluation, for example, will require validation of
