More than a dozen Michigan Tech faculty members and researchers have gone on the record in support of a ballot initiative designed to give a big boost to the state’s renewable energy industry. If passed by the voters in November, the initiative would require that 25 percent of Michigan’s electricity be generated using renewable energy sources by the year 2025. A July 19 letter released by the Union of Concerned Scientists supporting the measure garnered more than 140 signatures from scientists and academics throughout the state, including 15 from Michigan Tech. Among the signers is associate professor Joshua Pearce.

Research Assistant Professor Pasi Lautala (CEE/MTTI) and CoPIs Assistant Professor John Hill (ME-EM) and Assistant Professor Paul Sanders (MSE) have received $400,000 from the University of Illinois at Urbana-Champaign for a two-year project, “National University Rail Transportation and Education Center (NURail).”

Jaroslaw (Jarek) Drelich has been named the Editor-in-Chief of a new journal entitled Surface Innovations to be launched in February 2013 by ICE Publishing. Surface Innovations is an interdisciplinary and international journal that will publish articles on scientific and engineering advances made in formulation and modification of surfaces and coatings. Superhydrophobicity, superhydrophlicity, self-cleaning, self-healing, anti-fouling, anti-bacterial, etc., have become important fundamental topics of surface science research community driven by curiosity of physics, chemistry, and biology of interaction phenomenon at surfaces and their enormous potential in practical applications. Materials having controlled-functionality surfaces and coatings are important to the manufacturing of new products for environmental control, liquid manipulation, nanotechnological advances, biomedical engineering, pharmacy, biotechnology, and many others, and are part of the most promising technological innovations of the 21st century.

Drelich to Edit New Journal on Surfaces and Coatings

“Controlled-functionality surfaces and coatings may lead to some of the most promising technological innovations of the 21st century,” Drelich said. “Areas of particular interest are environmental control, liquid manipulation, nanotech devices, biomedical engineering, pharmacology and biotechnology.”

The research of professor Joshua Pearce (MSE/ECE) on solar photovoltaic thermal hybrid systems is featured in the press and on radio and television, including the Whig Standard, Materials Today, KROCK1057, CKNW and TV CKWS.

As well, his work appeared on numerous online green-energy news sites.

Here’s a Tiny Solar-Thermal System for Your Tiny House

Lead researcher Joshua Pearce focused on thin-film silicon technology, which is far cheaper than conventional solar cells based on crystalline silicon. For rooftop applications, it also has a weight advantage.

Hybrid Solar Electric/Solar Thermal Panels Could Make Rooftop Solar Mainstream

You don’t have to cool down thin-film silicon to make it work. In fact, Pearce’s group discovered that by heating it to solar-thermal operating temperatures, near the boiling point of water, they could make thicker cells that largely overcame the Staebler-Wronski effect. When they applied the thin-film silicon directly to a solar thermal energy collector, they also found that by spike annealing (baking the cell once a day), they boosted the solar cell’s electrical efficiency by over 10 percent.

“These studies open up an entirely new application of amorphous silicon and make a highly-economic PVT possible,” says Dr. Pearce. “We need both solar electricity and solar heating in Canada but we are running into ‘roof real estate’ issues. Now people can have both their solar electricity and solar heating combined in a nice tidy package.”

CleanTechnica, a clean technology news website, published an article about the research of Associate Professor Yun Hang Hu on using graphene, a two-dimensional honeycomb of carbon atoms, to improve the efficiency of solar panels.

“The excellent electrical conductivity of graphene sheets allows them to act as bridges, accelerating electron transfer from the titanium dioxide to the photoelectrode,” said Hu.

Michigan Tech scientists find a clean source of energy

“Carbon dioxide is very stable so normally it’s very typical to convert carbon dioxide to another useful compound. We found a way to convert carbon dioxide into carbon nitride with energy release,” said Yun Hang Hu, Michigan Tech professor.

“The single biggest contribution to carbon dioxide into the atmosphere is power plants. We get electricity from a power plant by burning coal,” Hang Hu said.
