Ultraviolet/Ozone as a tool to control grafting density in surface-initiated controlled-radical polymerizations via ablation of bromine

July 21, 2016
Author(s)
Richard J. Sheridan, Sara V. Orski, Shinichiro Muramoto, Christopher M. Stafford, Kathryn L. Beers
We used an ultraviolet-ozone (UVO) cleaner to create substrates for atom-transfer radical polymerization (ATRP) with varying surface initiator coverage. We collected complementary time-of-flight secondary ion mass spectrometry (ToF-SIMS) and X-ray

Redox sorting of carbon nanotubes

March 17, 2015
Author(s)
Hui Gui, Jason K. Streit, Jeffrey Fagan, Angela R. Hight Walker, Chongwu Zhou, Ming Zheng
This work expands the redox chemistry of single-wall carbon nanotube (SWCNT) by investigating its role in a number of SWCNT sorting processes. Using a polyethylene glycol (PEG)/dextran (DX) aqueous two-phase system, we show that electron-transfer reaction

Alkylperoxy Radical Photochemistry in Organic Aerosol Formation Processes

December 9, 2013
Author(s)
Alicia Kalafut-Pettibone, Joseph Klems, Donald R. Burgess Jr., William S. McGivern
Recent studies have shown that 254 nm light can be used to generate organic aerosol from iodoalkane/air mixtures via photodissociation of the C−I bond and subsequent oxidation of the single radical isomer. We examine organic aerosol formed from 1

Stirred-Reactor Simulations of Enhanced Reaction in the Presence of Fire Suppressants

October 12, 2011
Author(s)
Gregory T. Linteris, Donald R. Burgess Jr., Fumiaki Takahashi, Viswanath R. Katta, Oliver Meier
Several agents are under consideration to replace CF3Br in suppressing aircraft cargo bays fires. In a Federal Aviation Administration performance test simulating the explosion of an aerosol can, however, the replacements, when added at sub-inerting

Apparatus for Screening Fire Suppression Efficiency of Dispersed Liquid Agents.

January 1, 2001
Author(s)
Jiann C. Yang, Michelle K. Donnelly, N C. Prive, William L. Grosshandler
This paper is an abridged version of NISTIR 6319. The design, construction, demonstration, and operation of a bench-scale device capable of screening the fire suppression efficiency of liquid agents are described in detail in this report. The apparatus is

Modeling and Measurements of Soot and Species in a Laminar Diffusion Flame.

December 1, 1996
Author(s)
I. M. Kennedy, C Yam, D. C. Rapp, R J. Santoro, Wing Tsang
A model of laminar, soot-laden ethene diffusion flames has been developed and compared with measurements in nonsooting and sooting flames. Concentrations of stable gas-phase species were measured with mass spectrometry; laser-induced fluorescence was used

Thermodynamics of Metal Agent Fire Extinguishment

January 1, 2002
Author(s)
J D. Mather, R E. Tapscott
The thermodynamics of oxides, carbonates, halides and related metal compounds involved in extinguishment by dry chemicals and metal agents has been analyzed. It is shown that lattice energies play an important role in determining the extinguishment

Author(s)
Nicholas Derimow, Jake Benzing, Orion Kafka, Newell Moser, Priya Pathare, Michael Walker, Frank DelRio, Nik Hrabe
In Part 2 of this paper series, high-throughput tensile testing and characterization of porosity, microstructure, and oxygen content was carried out on Ti-6Al-4V samples that were fabricated via electron beam powder-bed fusion (PBF-EB) to test our

Substrate specificity and excision kinetics of natural polymorphic variants and phosphomimetic mutants of human 8-oxoguanine-DNA glycosylase

September 1, 2009
Author(s)
Viktoriya Sidorenko, Arthur P. Grollman, Pawel Jaruga, Miral M. Dizdar, Dmitry Zharhov
Human 8-oxoguanine-DNA-glycosylase (OGG1) efficiently removes mutagenic 8-oxoguanine (8-oxoGua) and 2,6-diamino-4-hydroxy-5-formamidopyrimidine (FapyGua) when paired with cytosine in damaged DNA. Excision of 8-oxoGua mispaired with adenine may lead to GT
