Characterizing Uncertainty of a Formaldehyde Reference Standard

April 18, 2016
Author(s)
Dustin Poppendieck
High performance buildings need to be energy efficient and provide adequate ventilation for indoor air quality, which can be made easier with low emitting building materials. Based in part on these motivations, the United States Environmental Protection

Engineered metal nanoparticles in the sub-nanomolar levels kill cancer cells

April 18, 2016
Author(s)
Yasmine C. Daniels, William A. MacCrehan, Shinichiro Muramoto, Gheorghe NMN Stan, Vitaly Vodyanoy, Oleg Pustovyy
Zinc and copper metal nanoparticles were produced from bulk metal rods by an underwater high-voltage discharge method. The metal nanoparticles, with estimated diameters of 1 nm to 2 nm, were determined to be more than 85 % non-oxidized. Exposure of rat RG2

Low-template DNA: A single DNA analysis or two replicates?

April 18, 2016
Author(s)
Simone N. Gittelson, Carolyn R. Steffen, Michael D. Coble
This study investigates the following two questions: (i) Should the DNA analyst concentrate the DNA extract into a single amplification or should he/she split it up to do two replicates? (ii) Given the electropherogram obtained from a first analysis, is it

Structural control of mixed ionic and electronic transport in conducting polymers

April 17, 2016
Author(s)
Jonathan Rivnay, Sahika Inal, Brian Collins, Michelle Sessolo, Eleni Stavrindou, Christopher Tassone, Dean DeLongchamp, George Malliaras
Poly(3,4-ethylenedioxythiophene) doped with poly(styrenesulfonate), PEDOT:PSS, has been utilized for over two decades as a stable, solution-processable conductor. While electrical properties have been the subject of intense materials investigation, recent

Device-Level Jitter as a Probe of Ultrafast Traps in High-k MOSFETs

April 16, 2016
Author(s)
Dmitry Veksler, Jason Campbell, Kin (Charles) Cheung, J. Zhong, H. Zhu, C. Zhao
A methodology for evaluation of ultra-fast interfacial traps, using jitter measurements as a probe, is developed. This methodology is applied to study the effect of PBTI stress on density of ultra-fast electron traps (with 500ps to 5ns characteristic

Bayesian Calibration of Transferable, Coarse-Grained Force Fields

April 15, 2016
Author(s)
Thomas W. Rosch, Frederick R. Phelan Jr., Paul Patrone
Generating and calibrating forces that are transferable across a range of state-points remains a challenging problem in coarse-grained (CG) molecular dynamics (MD). In this work, we present a Bayesian correction algorithm, inspired by ideas from

Combined Effects of High-Dose Bisphenol A and Oxidizing Agent (KBrO3) on Cellular Microenvironment, Gene Expression, and Chromatin Structure of Ku70-deficient Mouse Embryonic Fibroblasts

April 15, 2016
Author(s)
Erdem Coskun, Pawel Jaruga, Miral M. Dizdar, Natalie Gassman, Samuel Wilson
Background: Exposure to the environmental endocrine disrupting chemical bisphenol A (BPA) has been reported to alter global gene expression, induce epigenetic modifications, and interfere with the complex regulatory networks of cells. In addition to these

Models for the Economics of Resilience

April 15, 2016
Author(s)
Stanley W. Gilbert, Bilal Ayyub
Estimating the economic burden of disasters requires appropriate models that account for key characteristics and decision making needs. Natural disasters in 2011 resulted in $366 billion in direct damages and 29,782 fatalities worldwide. Average annual

Pressure-Resistant Intermediate Valence in the Kondo Insulator SmB 6

April 15, 2016
Author(s)
Nicholas P. Butch, Johnpierre Paglione, Paul Chow, Yuming Xiao, Chris A. Marianetti, Corwin H. Booth, Jason R. Jeffries
Resonant x-ray emission spectroscopy (RXES) was used to determine the pressure dependence of the f-electron occupancy in the Kondo insulator SmB 6. Applied pressure reduces the f-occupancy, but surprisingly, the material maintains a significant divalent
