Porous Graphene Oxide Frameworks: Synthesis and Gas Sorption Properties

July 1, 2011
Author(s)
Gadipelli Srinivas, Jacob Burress, Jamie Ford, Taner Yildirim
We report detailed synthesis of a range of porous graphene oxide frameworks (GOFs) by expansion of graphene oxide (GO) sheets with various linear boronic acid pillaring units in a solvothermal reaction. The GOF structures develop through boronate-ester

Stable isotope-labeling of DNA repair proteins, and their purification and characterization

July 1, 2011
Author(s)
M Miral Dizdar, Pawel Jaruga, Prasad T. Reddy, Bryant C. Nelson, Mark S. Lowenthal
Reduced DNA repair capacity is associated with increased risk for a variety of disease processes including carcinogenesis. Thus, DNA repair proteins have the potential to be used as important predictive, prognostic and therapeutic biomarkers in cancer and

Vacuum technology considerations for mass metrology

July 1, 2011
Author(s)
Patrick J. Abbott, Zeina J. Kubarych
Vacuum weighing of mass artifacts eliminates the necessity of air buoyancy correction and its contribution to the measurement uncertainty. Vacuum weighing is also an important process in the experiments currently underway for the redefinition of the SI

Characterization of Three Berry Standard Reference Materials for Nutrients

June 30, 2011
Author(s)
Laura J. Wood, Katherine E. Sharpless, Monique Pichon, Barbara J. Porter, James H. Yen
The National Institute of Standards and Technology (NIST) has been working with the National Institutes of Health Office of Dietary Supplements to produce Standard Reference Materials (SRMs) of interest to analysts of dietary supplements. Some of these

Recent Developments in Millimeter and Submillimeter Metrology at NIST

June 30, 2011
Author(s)
Ronald A. Ginley
The millimeter and submillimeter frequency ranges are becoming very important to today’s electronics, security and communication industries. NIST has undertaken a research program to aggressively pursue this area. This paper will cover the millimeter
