Protein labeling in Escherichia coli with 2H, 13C and 15N

August 23, 2015
Author(s)
Zvi Kelman, Prasad T. Reddy
A number of structural biology techniques such as nuclear magnetic resonance (NMR) and small-angle neutron scattering (SANS) can be performed with proteins with nuclei at natural isotope abundance. However, the use of proteins labeled with heavy isotopes

Enhanced Thermoelectric Properties for Cu2ZnSnSe4 with Ga-doping

August 22, 2015
Author(s)
Kaya Wei, Laura Beauchemin, Hsin Wang, Joshua B. Martin, George S. Nolas
Gallium doped Cu2ZnSnSe4 quaternary chalcogenides with and without excess Cu have been synthesized by elemental reaction and densified using hot pressing in order to investigate their high temperature thermoelectric properties. The resistivity, ρ, and

Bringing The Past Into The Present: the NIST Legacy Publications

August 21, 2015
Author(s)
Katelynd E. Bucher, Regina L. Avila, Andrea M. Medina-Smith
Since 2009, the Information Services Office (ISO) at the National Institute of Standards and Technology (NIST) has been digitizing a legacy publication collection of technical reports and other materials published by the agency since its founding in 1901

Overwhelming thermomechanical motion with microwave radiation pressure shot noise

August 21, 2015
Author(s)
John D. Teufel, Florent Q. Lecocq, Raymond W. Simmonds
We measure the fundamental noise processes associated with a continuous linear position measurement of a micromechanical membrane incorporated in a microwave cavity optomechanical circuit. We observe the trade-o ff between the two fundamental sources of

The PTEN Tumor Suppressor Forms Homodimers in Solution

August 21, 2015
Author(s)
Frank Heinrich, Srinivas Chakravarthy, Hirsh Nanda, Antonella Papa, Pier Paolo Pandolfi, Alonzo H. Ross, Rakesh K. Harishchandra, Arne Gericke, Peter M. Loesche
The PTEN tumor suppressor exerts phosphatase activity on PI(3,4,5)P 3 in the plasma membrane and was recently reported to dimerize in cell models. Here we show that PTEN forms homodimers in vitro and determine a structural model of the complex from SAXS

Computer Security Division 2014 Annual Report

August 20, 2015
Author(s)
Patrick D. O'Reilly, Gregory A. Witte, Larry Feldman
Title III of the E-Government Act of 2002, entitled the Federal Information Security Management Act (FISMA) of 2002, requires NIST to prepare an annual public report on activities undertaken in the previous year, and planned for the coming year, to carry

gtklogger: A Tool For Systematically Testing Graphical User Interfaces

August 20, 2015
Author(s)
Stephen A. Langer, Faical Y. Congo, Andrew C. Reid, Rhonald Lua, Valerie R. Coffman
We describe a scheme for systematically testing the operation of a graphical user interface. The scheme provides a capability for generating event logs, which are recordings of a user session with the interface. These logs can be annotated with assertion

Probing the Structure, Composition and Spatial Distribution of Ligands on Gold Nanorods

August 20, 2015
Author(s)
Michael J. A. Hore, Xingchen Ye, Jamie Ford, Yuzhi Gao, Jiayang Fei, Qiong Wu, Stuart J. Rowan, Russell J. Composto, Christopher B. Murray, Boualem Hammouda
The structure and size of ligands attached to the surfaces of gold nanorods, such as adsorbed surfactants or grafted polymers, are important considerations that facilitate the use of such nanoparticles in the human body, in advanced materials for energy

Tuning photo-catalytic activities of TiO2 nanoparticles using dimethacrylate resins

August 20, 2015
Author(s)
Jirun Sun, Stephanie S. Watson, David Allsopp, Deborah Jacobs, Drago Skrtic
Unique photo-catalytic activities (PCAs) of titanium dioxide nanoparticles (TiO2 NPs) made them attractive in many potential applications for medical devices. This study examined the benefits of the PCAs of TiO2 NPs through functionalization of the TiO2

Dimensional Reduction of Duplex DNA Under Nanofluidic Slit Confinement

August 19, 2015
Author(s)
Luis Fernando Vargas Lara, Jack F. Douglas, Samuel M. Stavis, Elizabeth A. Strychalski, Jon C. Geist, Brian J. Nablo
There has been much recent interest in the dimensional properties of duplex DNA under nanoscale confinement conditions as a problem of fundamental interest in both technological and biological fields. This has led to a series of measurements by
