Effect of N-Terminal Glutamic Acid and Glutamine on Fragmentation of Peptide Ions

March 27, 2010
Author(s)
Bhaskar Godugu, Pedatsur Neta, Yamil Simon, Stephen Stein
A prominent dissociation path for electrospray generated tryptic peptide ions is the dissociation of the peptide bond linking the second and third residues from the amino-terminus. The formation of the resulting b 2 and y n-2 fragments has been

AP210 Edition 2 Concept of Operations

March 26, 2010
Author(s)
Kevin G. Brady, Jamie Stori, Thomas Thurman
One of the most prevalent requirements of manufacturing industries today is the need to exchange and share product information within and between enterprises. This becomes almost impossible without a standardized, computer-interpretable method of

Building Information Exchange for Fire Responders Workshop: Proceedings

March 26, 2010
Author(s)
Jason D. Averill, David G. Holmberg, Alan B. Vinh, William D. Davis
Presently, there is no integrated solution for delivering building data into the hands of emergency responders. Technically, there are many challenges to collect, format, process, integrate and transport building data out of the building. Beyond this, the

N-Pyrrolidine Functionalized C 60 -Fullerenes/Epoxy Nanocomposites

March 26, 2010
Author(s)
Mickey Richardson, Eun S. Park, Jaehyun Kim, Gale A. Holmes
A small series of functionalized C60-fullerene/epoxy nanocomposites were prepared, and their respective ultimate tensile strengths were determined. The functionalization route of the fullerenes was performed using the well-known Prato reaction, with

Wrinkling and Strain Softening in Single-Wall Carbon Nanotube Membranes

March 26, 2010
Author(s)
Erik K. Hobbie, Daneesh O. Simien, Jeffrey A. Fagan, JiYeon Huh, Jun Y. Chung, Steven D. Hudson, Jan Obrzut, Jack F. Douglas, Christopher M. Stafford
Ultrathin layers of single-wall carbon nanotubes (SWCNTs) show considerable promise for applications ranging from fuel-cell membranes and biochemical sensors to bioactive films and transparent electrodes. The high conductivity and extreme anisotropy of

A RESTful Web Service for Virtual Supply Chain Time Management

March 25, 2010
Author(s)
Guillaume Radde
A common issue when building distributed simulations is the issue of time management. Each discrete event simulation has its own notion of time, and a mechanism needs to be set up to allow each simulation to run at the same pace. Different architectures

Methods for TEM analysis of NISTs SWCNT SRM

March 25, 2010
Author(s)
Roy H. Geiss, Elisabeth Mansfield, Jeffrey A. Fagan
The National Institute of Standards and Technology (NIST) is developing a series of single-walled carbon nanotube, SWCNT, reference materials, RMs, to provide researchers with well characterized materials for their applications. The SWCNT reference

Standard Reference Data for the Thermophysical Properties of Biofuels

March 25, 2010
Author(s)
Mark O. McLinden, Thomas J. Bruno, Michael D. Frenkel, Marcia L. Huber
The thermophysical properties of biofuels are required for the efficient design of every step in their production, distribution, and utilization. We provide an overview of properties research at the National Institute of Standards and Technology (NIST). We

Certification of Drugs of Abuse in a Human Serum Standard Reference Material: SRM 1959

March 24, 2010
Author(s)
Susan S. Tai, Jocelyn L. Prendergast, Lorna T. Sniegoski, Michael J. Welch, Karen W. Phinney, Nien F. Zhang
A new Standard Reference Material (SRM) for drugs of abuse in human serum (SRM 1959) has been developed. SRM 1959 is a frozen human serum material fortified with seven drugs of abuse, benzoylecgonine (BZE), methadone (METH), methamphetamine (MAMP)

Onset of Convection in Binary Liquid Layers

March 24, 2010
Author(s)
Geoffrey B. McFadden, Sam R. Coriell, Aaron Lott
We perform linear stability calculations for horizontal bilayers of a two-component fluid that can undergo a phase transformation, taking into account both buoyancy effects and thermocapillary effects in the presence of a vertical temperature gradient

Structural analysis of multilayer graphene via atomic moire interferometry

March 24, 2010
Author(s)
David L. Miller, Kevin Kubista, Gregory M. Rutter, Ming Ruan, Walt A. de Heer, Phillip First, Joseph A. Stroscio
The rotation of stacked honeycomb lattices produces an observable moir e pattern in the topography of scanning tunneling microscopy images, which have long been observed in highly-oriented pyrolytic graphite due to rotation of the surface layer relative to

The Solidification of an Ideal Ternary Alloy in a Mushy Layer

March 24, 2010
Author(s)
Daniel M. Anderson, Geoffrey B. McFadden, Sam R. Coriell, Bruce Murray
We consider a model for the solidification of an ideal ternary alloy in a mushy layer that incorporates the effects thermal and solutal diffusion, convection and solidification. Our results reveal that although the temperature and solute fields are

Compressive stress effect on the radial elastic modulus of oxidized Si nanowires

March 23, 2010
Author(s)
Gheorghe Stan, Sergiy Krylyuk, Albert Davydov, Robert F. Cook
Detailed understanding and optimal control of the properties of Si nanowires are essential steps in developing Si nanoscale circuitry. In this work, we have investigated mechanical properties of as-grown and oxidized Si nanowires as a function of their

Computer Security Division 2009 Annual Report

March 23, 2010
Author(s)
Patrick D. O'Reilly
This annual report covers the work conducted within the National Institute of Standards and Technology's Computer Security Division during Fiscal Year 2009. It discusses all projects and programs within the Division, staff highlights, and publications.

Improved NIST Airspeed Calibration Facility

March 23, 2010
Author(s)
Iosif I. Shinder, J. M. Hall, Michael R. Moldover
The National Institute of Standards and Technology (NIST) uses a laser Doppler anemometer (LDA) as a working standard for airspeed calibrations in the range 0.15 m/s to 75 m/s (0.34 to 168 miles/hour). We report improved procedures for calibrating the LDA

Towards Standardized Waveguide Sizes and Interfaces for Submillimeter Wavelengths

March 22, 2010
Author(s)
Ronald A. Ginley, Dylan Williams, N M. Ridler, J L. Hesler, Anthony R. Kerr, R D. Pollard
This paper describes an activity that has begun recently to develop an international standard for rectangular metallic waveguides and their interfaces for frequencies of 110 GHz and above. The IEEE's Microwave Theory and Techniques Society (MTT-S) is
