Impact of Hose Streams on Air Flows inside a Structure

October 3, 2016
Author(s)
Joseph M. Willi, Daniel M. Madrzykowski, Craig G. Weinschenk
Fire suppression tactics using hose streams can affect ventilation in a structure and may impact the movement of smoke and heat through a structure. Seven series of experiments were conducted to study the impact of different hose stream and nozzle movement

Physical properties of Al doped Ba hexagonal ferrite thin films

January 22, 2013
Author(s)
Harward Ian, Yan Nie, Daming Chen, Josh Baptist, Justin Shaw, Eva J. Liskova, Stefan Visnovsky, Petr Siroky, Michal Lesnak, Jaromir Pistora, Zbigniew Celinski
We developed the thin film microwave magnetic material, M-type barium hexagonal ferrite (BaM) doped with Al, for signal processing devices operating above 40 GHz with little to no applied magnetic field. Al was chosen as the dopant material because it

Establishing an upper bound on contact resistivity of ohmic contacts to n-GaN nanowires

April 1, 2014
Author(s)
Paul T. Blanchard, Kristine A. Bertness, Todd E. Harvey, Norman A. Sanford
Contact resistivity ρ c is an important figure of merit in evaluating and improving the performance of electronic and optoelectronic devices. Due to the small size, unique morphology, and uncertain transport properties of semiconductor nanowires (NWs)
