Ask Dr. MST
"Dr. MST" is a web based activity, which provides the opportunity for instructors to pose materials science related questions and/or provide advice via the website. Volunteers have been identified and will provide insight, guidance and regional support to answer these questions. Recruitment for additional volunteers is an ongoing process and MatEd plans to strengthen this resource with the use of its partners and collaborators. Industry professionals and college faculty, as well as contributing members with experience in advanced materials technology instruction will provide the needed input in the Dr. MST and the regional support system.
This part of the website is under construction. If you have a question for Dr. MST, please email us at MatEd@edcc.edu.

Question: Many fibers are synthesized from a petrochemical base (from oil---a fossil fuel). Is it possible to make a comfortable, durable polo shirt from fibers that are synthesized
from corn, a completely renewable chemical feedstock?
Answer: A Benson, MN company is making shirts from corn that you can wear for work or play. The shirts look and feel like cotton, but they wick moisture away from the body just like shirts made from high-end synthetic fabrics, says Don Lenz, CEO of Future Products, Inc. The fiber is called Ingeo (In-gee-o), which means ‘ingredients from the earth.’ A totally renewable product made from corn, Ingeo contains no petroleum byproducts like synthetics and other fabrics. It doesn’t pill, shrink, wrinkle or stain. It’s 100 percent biodegradable, making it the perfect “green” fabric, Lenz says. “It’s the fabric of the century.” Cargill Inc. makes Ingeo at its new $120 million NatureWorks plant near Blair, NE. It mills corn kernels into starch, then sugar. Enzymes ferment the sugar to produce lactic acid, which is transformed into pellets and extruded into a fiber that can be used in everything from clothing and carpets to packaging containers.

Question: I attended New 2007 and built a Tensile Impact Tester as Dr. Mir M. Atiquillah describes in his project description on the MatEd website. I tried using the tester on a Corelle plate and I couldn't get it to break. Do you know why?
Answer: Look at Lab 3-- "Fracture Resistant Ceramics" in the "Simple and Effective In-class Experiments and Demonstrations" section of the Labs & Demos folder for a full answer.

Question: I am building the Strength Testing machine as shown in "Properties of Fibers and Fabrics" module. I am having a problem finding a luggage scale. Any suggestions?
Answer: A weight scale, found at a local hardware store, or a game scale that can be found at a sporting goods store could be substituted.

Question: With the new Boeing 787 drawing such interest for my students, I would like to demonstrate composite airfoils and their uses in aviation. Any suggestions?
Answer: Go to the MatEd website home page and click on Curriculum Modules button and which takes you to the CWIS National Digital Library. Then do a search for curriculum/labs with key words including “composites” and “airfoils”. You will find a lab developed by the Pacific Northwest National Laboratory (PNNL) on this subject.

Question:> I am looking for something to "grab" my students into the composites world and help them understand this technology and make a lasting impression. Do you have any ideas?
Answer:> Try the PNNL MST Composites 8.35 Peanut Brittle exercise in the composites curriculum modules. This will surely peak their interest and their appetite.
