QUANTITY: An Isobaric Tag for Quantitative Glycomics

November 30, 2015
Author(s)
Shuang Yang, Meiyao Wang, Lijun Chen, Illarion Turko, Karen W. Phinney, Shuwei Li
We describe the design and synthesis of a novel set of iso-baric tags for quantitative glycan profiling, which will have broad applications in carbohydrate based biomarker dis-covery, therapeutic protein characterization, and vaccine development.

Quantized Hall resistance in large-scale monolayer graphene

November 28, 2015
Author(s)
Yanfei Yang, Chiashain Chuang, Chieh W. Liu, Randolph Elmquist
Abstract: Graphene is an atomic-thickness carbon lattice that can be exfoliated from solid graphite or grown using high temperature processing methods on a variety of substrates. Many practical applications of large-area graphene, however, are limited by

Author(s)
Kiwook Jung, Katherine C. Morris, Kevin W. Lyons, Swee K. Leong, Hyunbo Cho
Smart Manufacturing Systems (SMS) need to be agile to adapt to new situations by using detailed, precise, and appropriate data for intelligent decision-making. The intricacy of the relationship of strategic goals to operational performance across the many

Short-Time Glassy Dynamics in Viscous Protein Solutions with Competing Interactions

November 27, 2015
Author(s)
P. Douglas Godfrin, Steven Hudson, Kunlun Hong, Lionel Porcar, Peter Falus, Norman J. Wagner, Yun Liu
Although there have been numerous investigations of the glass transition for colloidal dispersions with only a short range attraction (SA), less is understood for systems interacting with a SA and an additional longer range repulsion (LR), which is

Dimensional Review of Scales for Forensic Photography

November 25, 2015
Author(s)
Massimiliano Ferrucci, Theodore D. Doiron, Robert M. Thompson, John Jones, Adam J. Freeman, Janice A. Neiman
Scales for forensic photography provide a geometrical reference in the photographic documentation of a crime scene. A common scale used by investigators is a plastic, L-shaped ruler that allows for a dimensional reference in the photographic documentation

Exciton-dominated Dielectric Function of Atomically Thin MoS2 Films

November 24, 2015
Author(s)
Yilin Yu, Yifei Yu, Yongqing Cui, Wei Li, Gurarslan Alper, Peelaers Hartwin, Aspnes David, Chris Van de Walle, Nhan Van Nguyen, Zhang Yong-Wei, Linyou Cao
The control of photons by field effects, like the gating of electrons, can revolutionize a wide range of fields by enabling active photonic devices whose functions could be manipulated with sophistication and speeds comparable to what achieved in modern

GC-MS/MS Measurement of Nanomaterial Induced Genotoxicity in Isolated DNA

November 24, 2015
Author(s)
Bryant C. Nelson, Elijah J. Petersen, Pawel Jaruga, M Miral Dizdar
Making accurate measurements of the environmental fate and environmental and biological effects of engineered nanomaterials (ENMs) is critical for reliable risk assessment of these materials. ENM induced oxidative stress and/or direct binding of ENMs to

GC/MS Measurement of Nanomaterial Induced Genotoxicity in Isolated DNA

Bryant C. Nelson, Elijah J. Petersen, Pawel Jaruga, M Miral Dizdar
Making accurate measurements of the environmental fate and environmental and biological effects of engineered nanomaterials (ENMs) is critical for reliable risk assessment of these materials. ENM induced oxidative stress and/or direct binding of ENMs to

LC-MS/MS Measurement of Nanomaterial Induced Genotoxicity in Isolated DNA

November 24, 2015
Author(s)
Bryant C. Nelson, Elijah J. Petersen, Pawel Jaruga, M Miral Dizdar
Making accurate measurements of the environmental fate and environmental and biological effects of engineered nanomaterials (ENMs) is critical for reliable risk assessment of these materials. However, the unique behaviors of ENMs may cause artifacts in

Observation of the reduction of thermal conductivity in a p-type nanostructured half-Heusler using neutron inelastic scattering

November 24, 2015
Author(s)
Winnie K. Wong-Ng, Jeffrey W. Lynn, Qingzhen Huang, Craig Brown, James A. Kaduk, Giri Joshi
To understand the role of the nanophase in reducing the lattice contribution of the thermal conductivity of thermoelectrics, the structure and phonon density of a p-type half-Heusler thermoelectric ingot (ingot-HH, nominal composition of (Hf0.5Zr0.5)Co(Sb0

Particle Fabrication Using Inkjet Printing onto Hydrophobic Surfaces for Optimization and Calibration of Trace Contraband Detection Sensors

November 24, 2015
Author(s)
John G. Gillen, Marcela N. Najarro, Matthew E. Staymates, Scott A. Wight, Marlon L. Walker, Jennifer R. Verkouteren, Eric S. Windsor, Aaron A. Urbas
A method has been developed to fabricate patterned arrays of micrometer-sized monodisperse solid particles of ammonium nitrate on hydrophobic silicon surfaces using inkjet printing. The method relies on dispensing one or more microdrops (typically 50 pL

Vapor-Liquid-Solid Etch of Semiconductor Surface Channels by Running Gold Nanodroplets

November 24, 2015
Author(s)
Babak Nikoobakht, Andrew A. Herzing, Shinichiro Muramoto, Jerry Tersoff
We show that Au nanoparticles spontaneously move across the (001) surface of InP, InAs, and GaP when heated in the presence of water vapor. As they move, the particles etch crystallographically aligned grooves into the surface. We show that this process is

Noncontact conductivity and dielectric measurement for high throughput roll-to-roll nanomanufacturing

Nathan D. Orloff, Christian J. Long, Jan Obrzut, Laurent Millaud, Francesca Mirri, Thomas R. Kole, Robert D. McMichael, Mattei Pasquali, Stephan J. Stranick, James A. Liddle
Advances in roll-to-roll processing of graphene [1] and carbon nanotube [2] have at last led to the continuous production of high-quality coatings and filaments, ushering in a wave of applications for flexible [3], [4] and wearable [5] electronics, woven

Neutron Scattering Study of Spin Ordering and Stripe Pinning in Superconducting La 1.93Sr d0.07^CuO 4

H. Jacobsen, I. A. Zaliznyak, A. T. Savici, B. L. Winn, S. Chang, M. Hucker, G. D. Gu, J. M. Tranquada, Peter M. Gehring
The relationships among charge order, spin fluctuations, and superconductivity in underdoped cuprates remain controversial. We use neutron scattering techniques to study these phenomena in La 1.93Sr 0.07CuO 4, a superconductor with a transition temperature

Adapting the Poisson-Influenced K-Means Algorithm for a Larger User Base

November 19, 2015
Author(s)
Brian P. Morris, Zachary H. Levine
A superconducting transition edge sensor (TES) can be a useful tool for counting the number of photons in a highly attenuated pulse of light, but it requires calibration for its outputs to be interpretable as photon numbers. The Poisson-Influenced K-Means

Chemical potential for light

November 19, 2015
Author(s)
Jacob M. Taylor, Mohammad Hafezi, Prabin Adhikari
Photons are not conserved in interactions with other matter. Consequently, when understanding the equation of state and thermodynamics of photons, while we have a concept of temperature for energy conservation, there is no equivalent chemical potential for
