From Electrons to Infrastructure: Engineering Concrete From The Bottom Up

April 6, 2011
Author(s)
Hamlin M. Jennings, Jeffrey W. Bullard
We argue that only an approach rooted in fundamental, mechanistic models of concrete materials offers a viable path for handling the enormous number of new variables that are being introduced as new materials are added to the design space, and as new

Magnetic Phase Diagram of Gd 2 Sn 2 O 7

April 6, 2011
Author(s)
R. S. Freitas, Jason S. Gardner
We have studied the magnetic phase diagram of the Heisenberg pyrochlore antiferromagnet Gd 2Sn 2O 7. Low temperature magnetic susceptibility measurements, as a function of the applied magnetic fields and temperature, shows the existence of multiple phase

Spin Liquid State in the S = 1/2 Triangular Lattice Ba 3 CuSb 2 O 9

April 6, 2011
Author(s)
H. D. Zhou, E. S. Choi, G. Li, L. Balicas, C. R. Wiebe, Yiming Qiu, John R. Copley, Jason S. Gardner
Spin liquids remain one of the most important objects of study in modern solid state physics as model systems of quantum magnetism. In this paper, we report the synthesis and characterization of a new spin liquid candidate, Ba 3CuSb 2O 9, which has a

Characterizing arbitrary CW waveforms with 1500 THz/s chirp rates

April 5, 2011
Author(s)
Ian R. Coddington, Fabrizio R. Giorgetta, Esther Baumann, William C. Swann, Nathan R. Newbury
A Dual frequency comb interferometer was constructed to monitor cw laser chirp rates exceeding 1500 THz/s with MHz level resolution and accuracy over a 3 THz spectral sweep. Monitoring of the chirped laser is continuous. Additionally, absolute frequency

Electrodeposition of Pt_(100-x)Pb_(x) Metastable Alloys and Intermetallics

April 4, 2011
Author(s)
Sun M. Hwang, John E. Bonevich, Jae Jeong Kim, Thomas P. Moffat
The electrodeposition of a series of metastable Pt-Pb alloys and intermetallic phases as well as elemental Pt is demonstrated using an acid electrolyte comprised of 0.05 mol/L Pb(ClO_4)_2 and/or 0.001 mol/L K_2PtCl_4. Pt-Pb films were deposited at various
