High-performance, vibration-immune, fiber-laser frequency comb

Author(s)
Esther Baumann, Fabrizio R. Giorgetta, Jeffrey W. Nicholson, William C. Swann, Ian R. Coddington, Nathan R. Newbury
We demonstrate an environmentally robust optical frequency comb based on a polarization-maintaining, allfiber, figure-eight laser. The comb is phase locked to a

Collisional Energy Dependence of Peptide Ion Fragmentation

Author(s)
Pedatsur Neta, Y Simon-Manso, Xiaoyu Yang, Stephen Stein
The energy dependence of fragmentation in a collision cell was measured for 2100 peptide ions derived from the digestion of twenty four common proteins. Most

Semiconducting Thienothiophene Copolymers: Design, Synthesis, Morphology and Performance in Thin Film Organic Transistors

Author(s)
Iain McCulloch, Martin Heeney, Michael L. Chabinyc, Dean DeLongchamp, Regis J. Kline, Michael Colle, Warren Duffy, Daniel A. Fischer, David J. Gundlach, Behrang Hamadani, Rick Hamilton, Lee J. Richter, Alberto Salleo, Martin Shkunov, David Sparrowe, Steve Tierney, Weimin Zhang
Organic semiconductors are emerging as a viable alternative to amorphous silicon in a range of thin film transistor devices. , With the possibility to formulate

A parametric interatomic potential for graphene

Author(s)
Vinod K. Tewary, B. Yang
A parametric interatomic potential is constructed for graphene. The potential energy consists of two parts: bond energy and radial interaction energy. The bond

Competition Between Self-Assembly and Surface Adsorption

Author(s)
Jacek Dudowicz, Jack F. Douglas, Karl Freed
We investigate a minimal equilibrium polymerization model of the general competition between self-assembly on a boundary and in solution that arises when an

Controlled Formation and Resistivity Scaling of Nickel Silicide Nanolines

Author(s)
Bin Li, Zhiquan Luo, Paul S. Ho, Li Shi, Lew Rabenberg, JiPing Zhou, Richard A. Allen, Michael W. Cresswell
We demonstrate a top-down method to fabricate nickel mono-silicide (NiSi) nanolines with smooth side walls and linewidths down to 15 nm. Four probe electrical

Roles of CIPM and IAPWS Standards for the Density of Water

Author(s)
Allan H. Harvey, R Span, K Fujii, M. Tanaka, Richard Davis
This contribution discusses the relative roles of the standard formulation for the density of liquid water recommended for metrology by the International

FiPy: PDEs in Python

Author(s)
Jonathan E. Guyer, Daniel Wheeler, James A. Warren
Partial differential equations (PDEs) are ubiquitous to the mathematical description of physical phenomena. They describe the relationships between functions of

Switching-off Hydrogen Peroxide Hydrogenation in the Direct Synthesis Process

Author(s)
Andrew A. Herzing, Jennifer Edwards, Benjamin Solsona, Edwin Ntainjua, Albert F. Carley, Graham J. Hutchings, Christopher J. Kiely
Hydrogen peroxide is an important disinfectant and bleach and is currently manufactured from an indirect process involving sequential hydrogenation/oxidation of
