Who We Are Welcome to the UWSP Solid State Ionics
Research Laboratory, directed by
Professor Robert
Beeken. This investigative program for undergraduates has been in
existence since 1987, supported in part by grants from Research Corporation
and the National Science Foundation. Students are provided the opportunity to
study ionic transport in solids and contribute significantly to fundamental
investigations of the structural and electrical properties of ionically
conducting materials. |
|
 |
X-ray Diffraction A fully automated system is designed to acquire diffraction patterns, fit experimental data to potential crystal lattices, calculate structural parameters, and match diffraction peaks to a database of 60,000 inorganic compounds. |
 |
Ionic Conductivity A fully automated system incorporates a 0.10-20 kHz vector impedance meter operating in conjunction with a sample environment that can be stabilized within half a degree over the 100-500 K temperature range. |

Research Alumni Alumni of the UWSP solid state ionics research
program typically continue studies in physics or materials science at the
graduate level. Some enter industrial positions, while others pursue high
school teaching careers. During the course of their undergraduate experience,
program participants are encouraged to publish their scholarly contributions in
standard scientific journals. In addition, many present papers or seminars at
state, national, or international conferences. Recent program alumni are listed
