Michigan Technological University researcher Reza Shahbazian-Yassar has discovered that perfection may not be all it’s cracked up to be, at least when it comes to designing materials for the next generation of lithium ion batteries. Shahbazian-Yassar investigates exotic new battery materials, which offer exotic new problems along with exciting possibilities. He hopes to turn one of those problems into an asset, with help from a $446,000 grant from the Division of Materials Research at the National Science Foundation.

Big disasters almost always result in big power failures. Not only do they take down the TV and fridge, they also wreak havoc with key infrastructure like cell towers. That can delay search and rescue operations at a time when minutes count. Now, a team led by Nina Mahmoudian of Michigan Technological University has developed a tabletop model of a robot team that can bring power to places that need it the most.

Michigan Technological University is well on its way to getting a $1.7 million, state-of-the-science transmission electron microscope (TEM), thanks to the National Science Foundation and a team of dedicated researchers led by Reza Shahbazian-Yassar.
“This will bring us to the forefront of electron microscopy,” said Shahbazian-Yassar, the principal investigator on the project. The new TEM will not only give researchers the ability to study atomic structure, it will also identify chemical composition with sensitivity close to a single atom.

Tolou Shokuhfar will be investigating the inner workings of a protein that plays a key role in human health with funding from a five-year, $400,000 Faculty Early Career Development (CAREER) Award.
Shokuhfar, an assistant professor of mechanical engineering-engineering mechanics at Michigan Technological University, will study the biomolecule ferritin, which stores iron in the body in a non-toxic, mineralized form and releases it safely. In humans, ferritin serves as a buffer between iron deficiency and iron overload, and when it malfunctions, it may be involved in a number of degenerative diseases, such as Alzheimer’s and Parkinson’s.

Mo Rastgaar has received a National Science Foundation grant of nearly $500,000 to make his new artificial limb design a reality. With the five-year Faculty Early Career Development (CAREER) Award, Rastgaar, an assistant professor of mechanical engineering-engineering mechanics, will further develop his powered ankle-foot prosthesis: an artificial lower leg with the unique ability to restore amputees’ mobility and agility.
Michigan Technological University is a partner in the newly formed $148 million American Lightweight Materials Manufacturing Innovation Institute (ALMMII). The new facility, to be headquartered in the metro-Detroit area, will be part of the National Network of Manufacturing Innovation, a federal initiative to help US manufacturers become more competitive and encourage investment in the United States.
The Department of Materials Science and Engineering and the Department of Mechanical Engineering-Engineering Mechanics are leading the Michigan Tech partnership with ALMMII. MSE Chair Stephen Kampe, Associate Professor Paul Sanders, Professor Walter Milligan and Research Professor Steven Mashl will be primary participants from MSE.
A graphene water balloon may soon open up new vistas for scientists seeking to understand health and disease at the most fundamental level.
Electron microscopes already provide amazingly clear images of samples just a few nanometers across. But if you want a good look at living tissue, look again.
“You can’t put liquid in an electron microscope,” says Tolou Shokuhfar, of Michigan Technological University. “So, if you have a hydrated sample—and all living things are hydrated—you have to freeze it, like a blueberry in an ice cube, and cut it into a million thin pieces, so the electrons can pass through. Only then can you image it to see what’s going on.”
Research by Assistant Professor Mo Rastgaar and graduate student Evandro Ficanha (MEEM) is featured on the website of the American Society of Mechanical Engineers. See “Computer-Controlled Prosthetic Closely Matches Action of Human Legs.” The Mumbai Mirror and Science World Report both published news stories about Assistant Professor Mo Rastgaar’s (ME-EM) work with the Mayo Clinic to develop a prosthetic foot that moves like a real human foot. See The Mumbai Mirror and Science World Report for the full story.
Assistant Professor Mo Rastgaar’s work designing and building a microprocessor-controlled artificial leg has been widely publicized, with more articles like the above appearing in IEEE Spectrum,, Medical Design Online, Gizmag,CNN, UPI Science News and many more outlets. He was also interviewed for Clear Channel One’s radio program Conversations in Health Care.
Walking is tricky business, as any toddler knows. And while most artificial feet and limbs do a pretty good job restoring mobility to people who have lost a leg, they have a ways to go before they equal the intricacy of a natural gait. As a result, over half of all amputees take a fall every year, compared to about one-third of people over 65.
In cooperation with a Mayo Clinic scientist, researchers at Michigan Technological University are taking a giant step toward solving the problem. They are making a bionic foot that could make an amputee’s walk in the park feel, well, like a walk in the park.
The secret lies in the ankle. Mo Rastgaar, an assistant professor of mechanical engineering–engineering mechanics, and PhD student Evandro Ficanha are working on a microprocessor-controlled ankle-foot prosthesis that comes close to achieving the innate range of motion of this highly complex joint.

A brighter, better, longer-lasting dental implant may soon be on its way to your dentist’s office. Dental implants are posts, usually made of titanium, that are surgically placed into the jawbone and topped with artificial teeth. More than dentures or bridges, implants mimic the look and feel of natural teeth. While most dental implants are successful, a small percentage fail and either fall out or must be removed. A scientist at Michigan Technological University wants to lower that rate to zero using nanotechnology.
