ion Publishable Glass Research with Undergraduates

Steve A. Feller, Coe College, DMR 0904615

• Annually, 25 undergraduates from Coe and other schools do glass research at Coe College in Cedar Rapids, Iowa.

• More than 225 students have participated in this research tradition that exceeds 30 years.

• We host an NSF-REU site on spectroscopy, including glass science.

• We have many visiting students do research with us and we send Coe students to collaborating labs.

• We are superbly equipped for this research, see next slide.

• We publish extensively—over 125 papers to date with undergraduates.

• We take students to present at national and international meetings; more than 300 to date.

ion Coe College Glass Research Student Outcomes

Steve A. Feller, Coe College, DMR 0904615 • 74% of over 200 Coe glass research alumni

attended graduate school upon graduation.• Recent and current graduate schools

attended include Harvard (2), Yale, Georgia Tech (3), Univ. of Minnesota (3), MIT, Northwestern, UC Davis, UC San Diego, Stanford (2), Colorado, Iowa State, Penn State, Missouri Univ. of Science and Tech (Rolla) (3), Lehigh, and several others.

• Employment of alums includes Corning, Inc. (2), Argonne National Lab, Georgia Tech, Applied Materials, Los Alamos National lab (3), Motorola, Inc., McKinsey Consulting, Rockwell-Collins (10), Medtronic, and numerous others.

• Numerous patents have been obtained and papers have been published by these alumni.

• Students become good citizens and give back to our community by participating in many science outreach programs at Coe. Laser Desorption TOF spectrum of lead borate glass

ion Glasses for Atomic Clocks

Steve A. Feller, Coe College, DMR 0904615 • Cesium is the element of choice for atomic

clocks. The second is defined as the time for exactly 9192631770 electromagnetic waves to be observed from a particular transition between two energy levels within the Cs-133 atom.

• To make a portable atomic clock a stable and abundant source of cesium is needed. We prepared cesium borate and borosilicate glasses for this purpose. The cesium is driven out of the glass as needed for the clock using electrical energy.

• Details maybe found in: . “All Solid State Ion-Conducting Cesium Source for Atomic Clocks,” Solid State Ionics 198 (47-49) J.J. Bernstein, S. Feller, A. Ramm, J. North, J. Maldonis, M. Mescher, W. Robbins, B. Timmons (2011). (bold names are Coe students).
