presentations.

9:45 - 10:05
Title:  RBS Analysis of Oxidation of CoMnO Coated Steel

Authors: Marc Binney, Richard Smith

Affiliation: Winona State University

Abstract:

Coated steel has been proposed for use in Solid Oxide Fuel Cells as  
interconnect material.  This study examines how samples of steel  
coated with Cobalt Manganese Oxide resist oxidation while in an  
oxygen rich and high temperature environment.  Specifically, two  
samples were studied.  One sample was 430 steel coated with the  
CoMnO, while the other had an additional bond coat of CrAlO between  
the steel and CoMnO.  While both samples reduced oxidation when  
compared to uncoated steel, the sample with the bond coat performed  
significantly better than the top coat only sample.

"Sound Card Physics"

Computer sound-cards provide an intuitive and surprisingly versatile  
tool
for investigating basic electronics concepts such as voltage division,
complex impedance, resonance, filtering, amplification, and phase
shifting.  Sound cards have several advantages: small size, ease of use,
and low cost.  Best of all, students are able to apply abstract
electronics concepts to something that they feel passionate about; their
own digital music.

*TITLE:  *Relativistic Electrons in a Box

*Presenter/Author:  *Dr. Linda Winkler

State University Moorhead


A recent article in American Journal of Physics^1 describes an  
inexpensive experiment that allows students to measure the mass of  
relativisitic electrons.  Beta particles from a thallium source  
follow a semi-circular trajectory in a region of uniform field, and  
the radius of orbit provides a measure of their effective mass.  I  
will show how we have implemented the experiment, and will describe  
some further cost-saving measures.   I will also show how we have  
used the set-up in a sophomore-level modern physics class.
