The present document will be part of the information upon which the Parties to the United Nations Montreal Protocol will base their future decisions regarding protection of the stratospheric ozone layer. OVERVIEW It has been recognized since the 1970s that

Quantification and Compensation of Unintentional Analyte Aggregation in Electrospray Sampling

March 30, 2011
Author(s)
Mingdong M. Li, Suvajyoti S. Guha, Rebecca A. Zangmeister, Michael J. Tarlov, Michael R. Zachariah
Electrospray (ES) sources are commonly used to introduce non-volatile materials (e.g. nanoparticles, proteins, etc.) in to the gas phase for characterization by mass spectrometry and ion mobility. Recent studies in our group using electrospray ion mobility

The 2010 Materials Research Society (MRS) Fall Meeting

Winnie Wong-Ng
The 2010 Materials Research Society (MRS) Fall Meeting took place in the Hynes Convention Center and the Sheraton Boston Hotel, starting the weekend following the Thanksgiving Holidays from November 27 to December 3. This large-scale meeting included forty

Influence of Periodic Patterning on the Magnetization Response of Micromagnetic Structures

March 29, 2011
Author(s)
SangHyun S. Lim, Thomas M. Wallis, Atif A. Imtiaz, Dazhen Gu, Thomas Cecil, Pavel Kabos, Pavol Krivoski
The magnetization dynamics of a single, patterned, thin-film Permalloy (Ni80Fe20, Py) elements embedded in a coplanar waveguide (CPW) are investigated. The anisotropic magnetoresistance (AMR) effect serves as the detection mechanism in current-modulated

Magnetization Reversal Mechanisms in Heusler Alloy Spin Valves

March 29, 2011
Author(s)
T. P. Ginley, Julie Borchers, Brian Kirby, Cindi L. Dennis, Matthew J. Carey, J. R. Childress
Ferromagnetic layers composed of Heusler alloys, which are predicted to be 100% spin polarized in bulk, have been incorporated into spin-valve sensors to improve performance. Transport studies of spin valves containing Co 2MnGe (CMG) in the free and pinned

Effects of shape distortions and imperfections on mode frequencies and collective linewidths in nanomagnets

March 28, 2011
Author(s)
Hans T. Nembach, Justin M. Shaw, Thomas J. Silva, Ward L. Johnson, Sudook A. Kim, Robert D. McMichael, Pavel Kabos
We used Brillouin light scattering to show that shape distortions in Ni80Fe20 nanoelements can have a dramatic effect on the measured linewidth of certain modes. By intentionally introducing an amount of “egg-like” shape distortion to an ideal elliptical

Superflow in a Toroidal Bose-Einstein Condensate: An Atom Circuit with a Tunable Weak Link

March 28, 2011
Author(s)
Kevin C. Wright, Anand Ramanathan, Sergio R. Muniz, Wendell Hill, Kristian Helmerson, William D. Phillips, Gretchen K. Campbell, Christopher Lobb
We have created a long-lived (40 s) persistent current in a toroidal Bose-Einstein condensate held in an all-optical trap. A repulsive optical barrier creates a tunable weak link in the condensate circuit, which can affect the current around the loop

Pressure Controlled Advanced Distillation Curve Analysis on Biodiesel Fuels

March 27, 2011
Author(s)
Bret Windom, Tara M. Lovestead, Thomas J. Bruno
Biodiesel fuel is an alternative fuel that can be derived from a number of renewable feedstocks including plant and vegetable oils, algae, animal fats, waste oils, etc. The fatty acid methyl ester (FAME) profile, and thus the resultant properties, of the
