Creating a Veteran-friendly Campus

When Jillian Richards came to Michigan Tech from the military, she traded discipline for self-discipline, regimen for free time, camaraderie for aloneness. The changes have been “a culture shock,” she says.

A native of Stevensville, Richards, 26, served eight years in the Army. Now she is a junior in civil engineering, and the transition from military to civilian life has been difficult. So much so, she sought counseling for insomnia and questioned whether getting out of the military was the right thing to do. Civilian life is a different world for her.

Consider: In the military, she was told, “This is what you have to learn, and this is how you’re going to learn it.” In college, she must be more self-directed. “We have to relearn how to learn,” she says.

Consider, too: In the military, there is a tight buddy system. “We looked out for each other. We trusted each other. We were brothers and sisters. Here I’m on my own. It’s frustrating.”

Then she stumbled on a fellow veteran at a birthday party. They started talking. “We were both frustrated with classes and other students,” she says. “I vented to him. He was someone who understood.”  The company of a compatriot buoyed her. She’s sleeping better these days and is now the president of the Student Veterans Organization.  The primary goal of the group, which has about 20 regulars, is to find a resource room where veterans can gather to meet, hang out and do homework together. “It would be good for our well-being,” Richards says. “Reaffirm we’re all doing the right thing.”

An estimated 200,000 soldiers a year are leaving the military, some returning home from war. Many will go to college on the GI Bill, which covers eight semesters of tuition, fees and books. (Veterans can transfer these benefits to their children.)  Against this backdrop, efforts are underway to make Michigan Tech a veteran-friendly campus.

It’s a distinct mission: veterans are older, more experienced, more mature, and often are married with families; as well, some are saddled with combat experience and suffer from post traumatic stress disorder (PTSD).  Rob Bishop, who is an advisor to the campus veterans group, says he would never have made it through college without a veteran-mentor. He hosted a webinar in late October for the campus; it addressed the needs of student-veterans.

The message: Veterans make good employees, but they don’t know it. They’re focused, reliable, good leaders and adept at teamwork, but they struggle to market themselves. They need to be confident that a leader in Iraq makes a leader in a corporation, that it’s not a big jump to go from being an artillery spotter to a student of physics.

Kathy Pintar, registration coordinator, is the point person who certifies benefits for veterans and monitors their academic progress.  “We, as a campus, have a lot more to learn and do to embrace these veterans,” she says.  She reports that there were 44 veterans on campus in spring 2009; now there are 86, ranging in age from 20 to 50.

Since 2008, Michigan Tech offers in-state tuition to out-of-state students who are the offspring or spouse of a person on active US military duty. Tech is also a “yellow-ribbon school”—a federal designation for a program where Tech commits $2,500, which the government matches, to help offset the tuition of nonresident students. Tech also provides veterans and current military personnel with a National Service Graduate Fellowship—a program initiated by the Graduate School to provide a tuition award to those who have provided service to our country.

Other initiatives are planned:

  • Holding a special session at Orientation to direct veterans to Tech’s wide array of student services, as well as their GI Bill benefits.
  • Steering them to the Veterans Hospital in Iron Mountain and local mental health providers.
  • Encouraging veterans in the larger community to connect with student-veterans.
  • Helping faculty learn to spot veterans who are suffering from PTSD.

Some plans are substantive; some are symbolic: In January, there will be a military appreciation night at a hockey game to recognize all veterans and ROTC cadets. Starting in December, veterans will sport red, white and blue honor cords at commencement, a salute to their service to the country. All of it is not only helpful, it’s good business. Says Bishop: “If we can create a network and an opportunity, we can become a destination for vets.”

Carbon Foam: The Key Ingredient of a Better Battery?

A lighter, greener, cheaper, longer-lasting battery. Who wouldn’t want that?

Tech researchers are working on it. Actually, their design is a twist on what’s called an asymmetric capacitor, a new type of electrical storage device that’s half capacitor, half battery. It may be a marriage made in heaven.

Capacitors store an electrical charge physically and have important advantages: they are lightweight and can be recharged (and discharged) rapidly and almost indefinitely. Plus, they generate very little heat, an important issue for electronic devices. However, they can only make use of about half of their stored charge.

Batteries, on the other hand, store electrical energy chemically and can release it over longer periods at a steady voltage. And they can usually store more energy than a capacitor. But batteries are heavy and take time to charge, and even the best can’t be recharged forever.

Enter asymmetric capacitors, which bring together the best of both worlds. On the capacitor side, energy is stored by electrolyte ions that are physically attracted to the charged surface of a carbon anode. Combined with a battery-style cathode, this design delivers nearly double the energy of a standard capacitor.

Now, Tech researchers have incorporated a novel material on the battery side to make an even better asymmetric capacitor.

Their cathode relies on nickel oxyhydroxide, the same material used in rechargeable nickel-cadmium or nickel-metal hydride batteries. “In most batteries that contain nickel oxyhydroxide, metallic nickel serves as a mechanical support and a current collector,” said chemistry professor Bahne Cornilsen, who has studied nickel electrodes for a number of years, initially with NASA support. A few years ago, the team had a chance to experiment with something different: Cornilsen suggested replacing the nickel with carbon foam.

Carbon foam has advantages over nickel. “It’s lighter and cheaper, so we thought maybe we could use it as a scaffold, filling its holes with nickel oxyhydroxide,” said Tony Rogers, associate professor of chemical engineering.

Carbon foam has a lot of holes to fill. “The carbon foam we are using has 72 percent porosity,” Rogers said. “That means 72 percent of its volume is empty space, so there’s plenty of room for the nickel oxyhydroxide. The carbon foam could also be made of renewable biomass, and that’s attractive.”

But how many times can you recharge their novel asymmetric capacitor? Nobody knows; so far, they haven’t been able to wear it out. “We’ve achieved over 127,000 cycles,” Rogers said.

Other asymmetric capacitors have similar numbers, but none have the carbon-foam edge that could make them even more desirable to consumers.

“Being lighter would give it a real advantage in handheld power tools and consumer electronics,” said Rogers. Hybrid electric vehicles are another potential market, since an asymmetric capacitor can charge and discharge more rapidly than a normal battery, making it useful for regenerative braking.

The group has applied for a patent on its new technology. Chemical engineering professor Michael Mullins is also a member of the research team. Graduate students contributing to the project are PhD graduate Matthew Chye and PhD student Wen Nee Yeo of the chemical engineering department and MS student Padmanaban Sasthan Kuttipillai and PhD student Jinjin Wang of the chemistry department.

The research is funded by the US Department of Energy, the Michigan Universities Commercialization Initiative, the Michigan Tech Research Excellence Fund and the Michigan Space Grant Consortium.

Hands, Minds–and Trees–Across the Sea

The forests of North America are different from those in Finland and Sweden, and the management of these forest resources differs historically and culturally. But environmental and forest resources issues are no respecters of national borders and global solutions are needed in today’s global economy. So Michigan Tech’s ATLANTIS program at the School of Forest Resources and Environmental Science (SFRES) is preparing graduate students on both sides of the Atlantic Ocean to tackle the world’s forest resources challenges.

ATLANTIS (Actions for Transatlantic Links and Academic Networks for Training and Integrated Studies) is an educational program jointly funded by the US Department of Education and the European Union. Only 16 such grants were awarded in 2008. Michigan Tech’s partner universities are North Carolina State, the University of Helsinki in Finland and the Swedish University of Agricultural Sciences.

Graduate students from each university spend up to a year at a foreign partner university, as well as up to a year at their home institution, earning dual master of science degrees from both their home and host universities. The program provides for faculty exchanges as well. So far 10 Michigan Tech faculty have spent time at the Swedish or Finnish universities to establish new collaborations, and a total of 24 graduate students will earn their degrees through this program.

An Estonian Student Comes to Tech

Tõnis Tõnisson, 25, is one of the ATLANTIS graduate students. An Estonian, he was studying in a cooperative program between the Estonian University of Life Sciences and the Swedish University of Life Sciences when he heard about the ATLANTIS program.

Tõnisson’s father works in forestry, and he wants to work in forest management. More than 50 percent of his native Estonia is covered with forests. “I grew up in the forest,” he explains, “and I wanted to study abroad.”

The fact that Michigan Tech courses are taught in English was no stumbling block for Tõnisson. He has studied English for 11 years, and the courses at the Swedish University of Life Sciences were taught in English. However, “I never had to speak English before. People here speak so fast, and they use more vocabulary than I know. But everybody has been really understanding and helpful.”

Another challenge was the high academic standards at Michigan Tech. “It is very different here,” Tõnisson says. “The university’s expectations of the students are much higher. I think I am learning much more here.”

Students here also have a lot more freedom than students in Estonia or Sweden, says Tõnisson. “And I am surprised at how open the people are here. They are much more talkative and friendly.”

Living on his own in Houghton, the Estonian student plunged right into campus life, playing soccer with international students over the summer and joining a bowling league.

Tõnisson spent a semester in Sweden and one in Finland before coming to Tech in January 2011. He is doing his graduate work with Kathy Halvorsen, a professor who holds a joint appointment in the Department of Social Sciences and the School of Forest Resources and Environmental Science. He will finish his dual master’s degree program in December and return to Estonia to complete another master’s degree for which he is already enrolled.

A Michigan Tech Student Goes to Scandinavia

Kassidy Yatso, a graduate student who also earned her Bachelor of Science in Applied Ecology and Environmental Science at Tech, spent one ATLANTIS semester at the University of Helsinki and the second semester at the Swedish University of Agricultural Sciences. She is back on campus now, completing her master’s degree work.

Yatso learned some surprising things while she was in Scandinavia, which she shared with the Tech community through a blog. (See Abroad.) For example, “No one in Sweden stands in line,” she discovered. “You push a button, and a paper slip comes out with a queue number. A large board shows which number they are serving, so you can guesstimate when to return for service.”

She also found that Swedish postage stamps, at 12 krona–approximately $1.85–are the most expensive stamps in the world. But the Swedish postal service is much more efficient and reliable than the one in Finland, the American student says.

Yatso’s academic experiences don’t reflect Tonisson’s impression that graduate school is more demanding in the US than it is in Scandinavia. In her April 17 blog, she describes a week that included a thesis defense; three demanding assignments for an intensive, two-week silviculture course; and an all-day field trip to Snogeholm to study multiple forest management techniques and current landscape architecture trends.

She still found time and energy to hear some live music by an all-girl Swedish band at a club in Malmo. “I was absolutely blown away,” she blogged. “They are now one of my favorite bands.”

No More Funding for ATLANTIS

The ATLANTIS program, a victim of federal budget cuts, won’t be funding any new programs, although Tech has already received the funds to complete its project. But Michigan Tech is going to try to find a way to continue the joint degree program with the Scandinavian universities.

“The European-American perspective provides invaluable benefit–a global perspective–to our students and the students from overseas,” says Chandrashekhar Joshi, professor of plant molecular genetics in SFRES. Joshi, who was graduate program director for SFRES when Michigan Tech applied for funding for the transatlantic master’s program, heads ATLANTIS at Tech.

“On return from abroad, the students’ vision has changed,” he says. “They become more outgoing. They transform into leaders. They seek more interactions with others. They act like global citizens.”

Yatso enthusiastically agrees. “The ATLANTIS program changed my life,” she says, “by giving me an opportunity to learn about science, culture and myself–while earning two master of science degrees. I have learned invaluable life lessons, skills and vocabulary along the way as well. The people I have met through ATLANTIS will forever be in my life and heart.”

Joshi points out that the dual degrees that the students earn are another benefit “of tremendous value in today’s job market.”

Since ATLANTIS began in 2008 in SFRES, two other international dual-degree programs funded by the same agencies have been established at Michigan Tech. One is in rail transportation; the other is in volcanology.

Tech Bucks National Trend in Graduate Enrollment

Across the United States, enrollment of new graduate students has declined somewhat, while the overall graduate school enrollment has increased only slightly (1.1 percent). However, those newest numbers, reported by the Council of Graduate Schools, are not reflected at Tech.

Bucking the national trend, graduate student enrollment here has increased nearly everywhere on campus. Total graduate enrollment sits at a new record of 1,303, while new master’s students have increased 6.9 percent, and new doctoral students have increased 4.3 percent.

So, why the difference?

“Students are interested in coming to our campus because of the quality of our faculty,” says Graduate School Dean Jackie Huntoon. “Many hear about us from friends and relatives who tell them that we provide great education opportunities in a wonderful place.”

According to Jacque Smith, director of graduate marketing and advancement for the Graduate School, there are other reasons.  “Of course, we provide a quality education,” he says, “and we combine a lot of resources with smaller numbers, so it’s a highly personalized graduate education.”

And research experiences at Tech are different, according to Smith. “We’ve always been known for hands-on, real-life research and lab experiences.” Less debt and more job offers are also incentives for students to seek education beyond the bachelor’s degree, he says.  “And, although it’s especially true for the STEM [science, technology, engineering, and math] disciplines, we are experiencing growth in most areas,” he says.
