On the Road – Mayer

Assistant Professor Audrey Mayer presented work on information theory and sustainable landscapes in a symposium on Coupled Human And Natural Systems (CHANS) at a meeting of the International Association of Landscape Ecology in Newport, Rhode Island, this week. Azad Henareh Khalyani, a PhD candidate in forest science, presented a poster on his remote-sensing work on a protected area in northwestern Iran.

Steer Your Students to this Opportunity for Collaboration

Research Assistant Professor Sara Robinson is crafting a pilot course with a decidedly interdisciplinary focus–for students of all backgrounds and majors, including engineers, scientists, chemists, artists, wood enthusiasts and writers.

“Wood in the Modern Age” will be offered beginning in fall 2012 semester. It is intended to develop a fundamental understanding of the properties, characteristics, and role of wood in today’s society–along with its importance in sustainable building.

The course will focus on wood as a biological material and expore its relationship to art, architecture, engineering and science. It is for both undergraduate and graduate students; class sessions will be in the evening.

The course work will culminate with a design project in which the knowledge gained–combined with the unique background of each student–will be applied to a final project. Class instruction will combine lecture, laboratory and studio time, as well as situational learning experiences.

This offering, which also will be open to students at Finlandia University, adds to the more than 100 classes at Tech that have a sustainability component. Robinson says it is a good fit for a world that is increasingly complex and interdependent.

Keeping Wood Preservatives Where They Belong: In the Wood

by Marcia Goodrich, Michigan Tech magazine editor

Pressure-treated wood is great stuff, but the chemicals used to preserve it from decay can leach out, where they can be toxic to bugs, fungi and other hapless creatures that have the bad luck to be in the neighborhood. Now, a team of scientists has used nanotechnology to keep the chemicals inside the wood where they belong.

“It’s a new method that uses nanoparticles to deliver preservatives into the lumber,” said chemistry professor Patricia Heiden. “In our experiments, it reduced the leaching of biocides by 90 percent.”

The nanoparticles are tiny spheres of gelatin or chitosan (a material found in the shells of shrimp and other shellfish) chemically modified to surround the fungicide tebuconazole. The little spheres require no special handling.

“You just pressure-treat the wood in the usual way,” Heiden said.

The initial tests show that the nanoparticle-treated wood is just as resistant to rot and insects as conventionally treated lumber. The researchers are now testing the wood in the warm, wet weather of Hawaii.

The research is funded by the US Environmental Protection Agency. Also contributing to the project are chemistry PhD student Xiaochu Ding and, from the School of Forest Research and Environmental Science, Research Engineer/Scientist II Dana Richter, Senior Research Engineer/Scientist Glenn Larkin, Assistant Research Scientist Erik Keranen and Professor Peter Laks.

Three students earn SURF Awards

The Summer Undergraduate Research Fellowship (SURF) program will support 20 students from across the University with funds from the Vice President for Research and the Honors Institute. The total funding for this summer’s program is $66,000. From the School of Forest Resources and Environmental Science, the following students were recipients:

Forestry major Rachel Mason earns All-American Honors

Rachel MasonRachel Mason earned her third All-American honor at the USSA Mariott Junior National Skiing Championships on Friday, March 9. She finished eighth in the five-kilometer classic race in a time of 15:11.

Rachel, along with 15 student-athlete teammates also earned National Ski Coaches Association All-Academic Ski Team honors. The student-athletes needed to have a 3.5 grade point average for the Fall semester of 2011.

The American Association for the Advancement of Science (AAAS) has posted an eight-minute audio slide show on its web site about Michigan Tech’s ongoing wolf-moose research at Isle Royale National Park. The presentation features Professor Emeritus Rolf Peterson and Associate Professor John Vucetich, as well as their colleague, Michael Nelson, an environmental ethicist at Michigan State University. Although the audio slide show is accessible only to members of AAAS, a free three-day trial membership will enable you to see it. Sign up for the free trial membership at AAAS.

Sara Claypoole – 2002

Sara Claypoole visited campus and the School from Pottstown , Pennsylvania during winter carnival. After graduating from Michigan Tech in Applied Ecology and Environmental Sciences, she went on to the University of Charleston. Sara says, “I’m a pharmacist with CVS Pharmacy and a proud owner of 10 acres of woods. In my spare time, I’ll be taking care of the woodlands.” She is planning for her first harvest in 2013.
