A Stent Event: Michigan Tech Students Mimic Blood Flow in the Lab

“…There’s not a lot of information on exactly how stents degrade in the body,” said Patrick Bowen, who just completed his BS in Materials Science and Engineering…

“In the past, in vivo and in vitro corrosion rates have always been different,” said Jaroslaw Drelich, an associate professor of materials science and engineering and the group’s other co-advisor. “These appear to be identical.”

Senior Design team members, in addition to Bowen, are Rebecca Franke, Judy Bryne, Ellen Pokorney, Jessica Rhadigan and Aaron Tauscher (Biomedical Engineering); and Jesse Gelbaugh (Materials Science and Engineering).


If You Have a Michigan Tech Degree, Bhakta Rath Knows You Can Do the Job

“We need to excite American students about the STEM fields, and if you excite the teachers, they excite the students,” Rath explains. He has successfully talked the Office of Naval Research into funding summer teachers’ camps.

Bhakta Rath ’58 is the associate director of research and head of the Material Science and Component Technology Directorate of the US Naval Research Laboratory. Rath earned his Master of Science in Metallurgy from Michigan Tech in 1958 and received an honorary doctorate in engineering when he spoke at Tech’s December 2007 Commencement. In 2008, he was elected to the National Academy of Engineering.



Nanoporous Materials for Energy and Environmental Application

Abstract

Metal-organic frameworks (MOFs) are a new class of nanoporous materials synthesized
in a “building-block” approach by self-assembly of metal or metal-oxide vertices
interconnected by rigid organic linker molecules. The rational synthesis approach opens
up the possibility of incorporating a wide variety of functional groups into the materials,
and these materials may lead to new advances in adsorption separations, gas storage,
sensing, and catalysis. Some of the most intensively studied applications are related to
solving energy and environmental problems, including hydrogen storage for fuel cell
vehicles, capture of CO2 from power plant exhaust, and energy efficient separations.
Because of the predictability of the synthetic routes and the nearly infinite number of
variations possible, molecular modeling is an attractive tool for screening new structures
before they are synthesized. Modeling can also provide insight into the molecular-level
details that lead to observed macroscopic properties. This talk will provide an overview
of MOFs and their potential applications, as well as efforts to predict their properties
using molecular modeling.

Biography

Randy Snurr is a Professor of Chemical and Biological Engineering at Northwestern University.
