Mixed-Surfactants as a Novel Approach to Atomic Engineering of Spin Valves

October 12, 2021
Author(s)
D X. Yang, H D. Chopra, P J. Chen, William F. Egelhoff Jr.
Previously, surfactants in ultra-high vacuum have been used to obtain smooth interfaces in giant magnetoresistance effect (GMR) spin valves for an enhanced GMR. In the present study, a novel extension to the surfactant approach has been developed, called

Terahertz circular variable filters

February 15, 2006
Author(s)
Erich N. Grossman, Charles Dietlein, A. Luukanen
We describe a novel class of millimeter-wave and terahertz monochrometers based on adiabatically tuned frequency-selective surfaces. They are analogous to the circular-variable filters commonly used in the infrared for low to moderate resolution

Measurement of the Flow Resistance of Vegetation

April 1, 2019
Author(s)
Ryan L. Falkenstein-Smith, Kevin B. McGrattan, Blaza Toman, Marco G. Fernandez
This report documents the measurement of the wind resistance of different types of vegetation. The measurements are made in a wind tunnel with a 2.0 m test section and 0.5 m by 0.5 m cross- section. Samples of vegetation have been cut into cubical volumes

Effect of Diamond Nanolubricant on R134A Pool Boiling Heat Transfer

December 15, 2009
Author(s)
Mark A. Kedzierski
This paper quantifies the influence of diamond nanoparticles on the pool boiling performance of R134a/polyolester mixtures on a roughened, horizontal, flat surface. Nanofluids are liquids that contain dispersed nano-size particles. A lubricant based

Second Preimage Attacks on Dithered Hash Functions

April 17, 2008
Author(s)
Elena Andreeva, Charles Bouillaguet, Pierre-Alain Fouque, Jonathan J. Hoch, John M. Kelsey, Adi Shamir, Sebastien Zimmer
We develop a new generic long-message second preimage attack, based on combining the techniques in the second preimage attacks of Dean Dean99} and Kelsey and Schneier KS05} with the herding attack of Kelsey and Kohno KK06}. We show that these generic
