Temperature and light intensity effects on the photodegradation of high-density polyethylene

May 11, 2019
Author(s)
Andrew W. Fairbrother, Hsiang C. Hsueh, Jae Hyun Kim, Deborah S. Jacobs, Lakesha N. Perry, David G. Goodwin, Christopher C. White, Stephanie S. Watson, Li Piin Sung
The photodegradation of polymers poses a serious challenge to their outdoor application, and results in significant financial loss due to early or unexpected system failure. A better understanding of their degradation kinetics aids the improvement of

Machine learning modeling of superconducting critical temperature

June 28, 2018
Author(s)
Aaron Gilad Kusne, Valentin Stanev, Ichiro Takeuchi
Superconductivity has been the focus of enormous research effort since its discovery more than a century ago. Yet, some features of this unique phenomenon remain poorly understood; prime among these is the connection between superconductivity and chemical

Examining Heat Treatment for Stabilization of the Lipidome

February 16, 2018
Author(s)
John Bowden, Candice Z. Ulmer, Christina Jones, Tracey Johnston, Jeremy P. Koelmel, Timothy J. Garrett, Richard A. Yost
Aim: To confidently determine lipid-based biomarkers, it is important to minimize variation introduced during preanalytical steps. We evaluated reducing variation associated with lipid measurements in invertebrate sentinel species using a state-of-the-art

Thermal Degradation Studies of Alkyl-Imidazolium Salts and Their Application in Nanocomposites

February 19, 2017
Author(s)
W H. Awad, Jeffrey W. Gilman, Marc R. Nyden, Richard H. Harris Jr., T E. Sutto, J H. Callahan, Paul C. Trulove, H X. DeLong
Increasing the thermal stability of organically modified layered silicates is one of the key points in the successful technical application of polymer layered-silicates nanocomposites on the industrial scale. To circumvent the detrimental effect of the

Quasi-Two-Dimensional Spin and Phonon Excitations in La 1.965 Ba 0.035 CuO 4

June 3, 2015
Author(s)
J. J. Wagman, Daniel E. Parshall, M. B. Stone, A. T. Savici, Yang Zhao, H. A. Dabkowska, B. D. Gaulin
We present time-of-flight inelastic neutron scattering measurements of La 1.965Ba 0.035Cu) 4 (LBCO), a lightly doped member of the high temperature superconducting La-based cuprate family. By using time-of-flight neutron instrumentation coupled with single

Unwanted Combustion Enhancement by C6F12O Fire Suppressant

August 7, 2012
Author(s)
Gregory T. Linteris, Valeri I. Babushok, Peter B. Sunderland, Fumiaki Takahashi, Viswanath R. Katta, Oliver Meier
Several agents are under consideration to replace CF3Br for use in suppressing fires in aircraft cargo bays. In a Federal Aviation Administration (FAA) performance test simulating the explosion of an aerosol can, however, the replacements, when added at

SEM imaging of ultra-high aspect ratio hole features

March 29, 2012
Author(s)
John S. Villarrubia, Aron Cepler, Benjamin D. Bunday, Bradley Thiel
… bottoms of at-node size beyond 10:1 AR contact holes in oxide has not yet been demonstrated. Nevertheless, holes and …

Predictive Gold Nanocluster Formation Controlled by Metal-Ligand Complexes

January 9, 2012
Author(s)
John M. Pettibone, Jeffrey W. Hudgens
The formation of ligand-protected transition metal nanoclusters in size-selective syntheses is driven by the inherent properties of the protecting ligands. We have previously reported the selective, monodisperse product formation of phosphine protected Au

Redox-Promoting Protein Motions in Rubredoxin

May 24, 2011
Author(s)
Jose M. Borreguero, Junhong He, F. Meilleur, Kevin Weiss, Craig Brown, D. A. A. Myles, Kenneth W. Herwig, Pratul K. Agarwal
Abstract Proteins are dynamic objects, constantly undergoing conformational fluctuations, yet the linkage between internal protein motion and function is widely debated. This manuscript reports on the characterization of temperature-activated collective

Building Electronic Function Into Nanoscale Molecular Architectures

August 30, 2007
Author(s)
H D. Abruna, M Ratner, Roger D. van Zee
The use of molecules in electronic circuit has been the subject of recent study. Experimentally, two-terminal, molecular rectifiers have been demonstrated, three-terminal, single-molecule transistors demonstrated, and electromechanical molecular switches
