Development of a new UHV/XHV pressure standard (Cold Atom Vacuum Standard)

November 10, 2017
Author(s)
Julia Scherschligt, James A. Fedchak, Daniel Barker, Stephen Eckel, Nikolai Klimov, Constantinos Makrides, Eite Tiesinga
The National Institute of Standards and Technology has recently begun a program to develop a primary pressure standard that is based on ultra-cold atoms, covering a pressure range of 1 × 10-6 Pa to 1 × 10-10 Pa and possibly lower. These pressures

Surface Modification of Cisplatin-Complexed Gold Nanoparticles and Its Influence on Colloidal Stability, Drug Loading, and Drug Release

November 10, 2017
Author(s)
Jiaojie Tan, Tae Joon Cho, De-Hao Tsai, Jingyu Liu, John M. Pettibone, Rian You, Michael R. Zachariah, Vincent A. Hackley
Cisplatin-complexed gold nanoparticles (PtII-AuNP) provide a promising strategy for chemo- radiation based anticancer drugs. Effective design of such platforms necessitates reliable assessment of surface engineering on a quantitative basis, and its

On the Melting Curve of Sulfur Hexafluoride

November 9, 2017
Author(s)
Allan H. Harvey
A previous correlation for the melting curve of sulfur hexafluoride (SF6) is inconsistent with the thermodynamic slope at the triple point derived from the Clapeyron equation. It is shown that this is probably due to the previous authors combining an

Resonant X-ray Emission of Hexagonal Boron Nitride

November 9, 2017
Author(s)
John T. Vinson, Terrence J Jach, Matthias Mueller, Rainer Unterumsberger, Burkhard Beckhoff
The electronic structure of hexagonal boron nitride ({\it h}-BN) is explored using measurements of x-ray absorption and resonant inelastic x-ray scattering (RIXS) at the nitrogen K edge (1{\it s}) in tandem with calculations of the same using many-body

Towards reliable RRAM performance: macro- and microscopic analysis of operation processes

November 9, 2017
Author(s)
Gennadi Bersuker, Dmitry Veksler, David M. Nminibapiel, Pragya Shrestha, Jason Campbell, Jason Ryan, Helmut Baumgart, Maribeth Mason, Kin P. Cheung
Resistive RAM technology promises superior performance and scalability while employing well- developed fabrication processes. Conductance is strongly affected by structural changes in oxide insulators that make cell switching properties extremely sensitive

Characterization for an Industrial Wireless Network in a Gas Sensing Scenario

November 8, 2017
Author(s)
Mohamed Hany, Rick Candell
Employing wireless communications in gas sensing and air quality monitoring is extremely essential in many industrial scenarios where wired networks cannot perform the task safely and effectively. In industrial environments, deploying wireless gas sensing

Gas Chromatographic Retention Behavior of Polycyclic Aromatic Hydrocarbons (PAHs) and Alkyl- Substituted PAHs on Two Stationary Phases of Different Selectivity

November 8, 2017
Author(s)
Federica Nalin, Lane C. Sander, Walter B. Wilson, Stephen A. Wise
Retention indices (RIs) for 45 polycyclic aromatic hydrocarbons (PAHs) and 63 methyl- substituted PAHs were determined by gas chromatography – mass spectrometry (GC-MS) using two different stationary phases: a 50% (mole fraction) phenyl-substituted

Indentation mapping revealed poroelastic, but not viscoelastic,properties spanning native zonal articular cartilage

November 8, 2017
Author(s)
Joseph Wahlquist, Frank W. DelRio, Mark Randolph, Aaron Aziz, Chelsea Heveran, Stephanie Bryant, Corey P. Neu, Virginia L. Ferguson
Osteoarthrosis is a debilitating disease affecting millions, yet engineering materials for cartilage regeneration has proven difficult because of the complex microstructure of this tissue. Articular cartilage, like many biological tissues, produces a time
