CEDAR FALLS, Iowa—Two patents were recently issued to Curt Hanson, University of Northern Iowa associate professor of chemistry, for his research at UNI.
Last November, a patent was granted for a pyrolysis method for increasing limonene oil produced from waste tires, and a novel oven to facilitate that method. This allowed him to study the chemical mechanisms of how scrap tire waste decomposes when heated.
“The results of this research permitted insight into optimizing pyrolysis as a recycling method,” according to Hanson.
The patent was authored by Hanson and two students, James Haworth, Des Moines, and Tim Burrell, Cedar Falls. He was also aided by James Olson, waste reduction specialist from the Iowa Waste Reduction Center located at UNI. The patent was funded by a grant by the UNI Recycling and Reuse Technology Transfer Center (RRTTC).
The second patent, issued in January, was for the development of a new design for an instrument for chemical analysis, called a multi-paths reflectron time-of-flight mass spectrometer. A prototype was constructed and proved to have improved operational characteristics, including better resolution and selectivity. This patent was supported through grants from the RRTTC and the Carver Foundation.

CEDAR FALLS, Iowa— Education majors at the University of Northern Iowa scheduled to have their student teaching experience during spring semester 2000, are completing the first of two nine-week student teaching assignments. Students teach in student teaching centers throughout the state, the nation and the world.
(Name) of (Hometown) is a student teacher at (School) in (Location) .
The purpose of student teaching is to provide a planned, carefully supervised learning experience that allows the student teacher to demonstrate resourcefulness and competence as a teacher in a real school setting. The program allows the student teacher to also improve this resourcefulness as a teacher.
Under the leadership of an experienced classroom supervisor, the student teacher's tasks include evaluating pupil progress, participating in extracurricular school activities, working with special area consultants, utilizing school and community resources, and analyzing the teacher-learning process.
Student teachers are also supervised by student teacher coordinators who make classroom observations, evaluate the student teachers' progress and conduct seminars on a regular basis. The coordinators are usually permanent residents in the student teaching center areas.
To be eligible for student teaching, a student must maintain a 2.4 average in a 4-point grading system and must be approved to take part in the teacher education program. Participants receive 15 semester hours of credit.
Note: to obtain a complete list of the student teachers, please contact the Office of Public Relations at (319)273-2761.
