Giulia Panegrossi, Jean-François Rysman, Daniele Casella, Anna Cinzia Marra, Paolo Sanò, and Mark S. Kulie published “CloudSat-based assessment of GPM Microwave Imager snowfall observation capabilities” in Remote Sensing on December 6, 2017.
The article describes a NASA Global Precipitation Measurement Microwave Imager (GMI) snowfall sensitivity study using CloudSat satellite radar data as evaluation dataset. The study illustrates complex high frequency microwave sensor signatures to snowfall events under different atmospheric conditions and microphysical composition. It defines environmental and snow-producing cloud composition thresholds where the 166 GHz GMI channel is sensitive to surface snowfall, thus providing useful guidance to improve GMI snowfall detection and estimation capabilities.

According to AIChE’s online news site, ChEnected.com, “Camelina-Derived Jet Fuel and Diesel: Sustainable Advanced Biofuels,” by Chemical Engineering Professor David R. Shonnard, director of the Michigan Tech Sustainable Futures Institute, Larry Williams of Targeted Growth, Inc., and Tom N. Kalnes of UOP LLC, a Honeywell Company, has an outstanding Altmetric Attention Score of 128. That places it in the top 5% of all research outputs scored by Altmetric.
Even though published in the AIChE journal Environmental Progress & Sustainable Energy (EP&SE) in 2010, the article is currently trending online. It has been mentioned this year by 14 news outlets, including Scientific American, Smithsonian, and Popular Mechanics. Altmetrics track the use and discussion of research from online discussions and forums, including social media, research blogs, public policy documents, news articles, and more.
In the article, Shonnard, Williams, and Kalnes discuss how bio-jet fuels derived from oil-rich feedstocks, such as camelina and algae, have been successfully tested in proof-of-concept flights. The American Society for Testing and Materials (ASTM) has approved a 50:50 blend of petroleum-based jet fuel and hydroprocessed renewable jet fuel for commercial and military flights.
Honeywell UPO LLC and Targeted Growth, Inc. funded the research on bio-jet fuel derived from camelina seeds developed by a Bozeman, Montana company, Sustainable Oil.
“Camelina, an oil seed crop, can be grown in more arid climates compared to many other plants that oil is derived from,” notes Shonnard. “Targeted Growth Inc. has identified 5 million acres across the country where camelina would be suitable as a rotation energy crop that would not interrupt food production. This could produce approximately 800 million gallons of camelina oil for conversion to renewable diesel or jet.”
In 2010, Shonnard completed a life cycle analysis (LCA) comparing camelina jet fuel with petroleum jet fuel, factoring in the greenhouse gas emissions from fertilizing production and use, growing, harvesting, oil recovery and conversion to jet fuel, and use of the renewable jet in applications. “Conventional camelina, that is camelina grown with current seed stock, can cut greenhouse gas emissions by 60 to 70 percent, with no loss of performance for the fuel. A newer strain of camelina, one that needs less fertilizer and yield more pounds per acre,could cut greenhouse gas emissions by up to 84 percent compared with jet fuel from petroleum, says Shonnard. “Next generation biofuels are true hydrocarbons and on a molecular level indistinguishable from fossil fuels,” he notes.
“With expected future gains in yields/acre, camelina oil production and hydroprocessing has the potential to provide the United States an estimated 800 million gallons per year of high-quality, climate-friendly, renewable jet fuel,” the study concludes.

The Fifth Annual Rekhi Innovation Challenge kicked off on Friday Nov. 10, 2017. Three Enterprise teams are competing for funding this year: Blue Marble Security, BoardSport Technologies and Velovations. The Rekhi Challenge is a crowdfunding competition to help promote and support student innovation and entrepreneurship through Michigan Tech’s crowdfunding site, Superior Ideas. The team that raises the most money will receive a monetary match of up to $5,000.
Monetary awards for total number of unique visitors, total number of unique funders, most social media engagement, most creative marketing plan and the first team to raise $1,000 will also be presented to teams at the conclusion of the competition.
Superior Ideas was established in 2012 to help bring university research and public service projects to life. The site uses crowdfunding to raise money and awareness for university research and public service projects that may not qualify for grant funding.
The Rekhi Innovation Challenge was developed in collaboration with the Enterprise Program Office and the Vice President for Research Office with support from Michigan Tech alumnus and longtime donor Kanwal Rekhi. The Silicon Valley-based entrepreneur, earned his master’s degree in electrical engineering from Michigan Tech in 1969.
Enterprise teams that have participated in past challenges include Innovative Global Solutions, Robotics Systems, Supermileage Systems, Aerospace, Blizzard Baja, GEAR and Open Source Hardware. Velovations took first place in the last competition with $2,550 in donations and a match of $2,550 from Rekhi, bringing the grand total to $5,100 in funding for their RENEW-U project.
RENEW-U is an ergometer for wheelchair users to exercise upper-extremity muscles in order to improve strength and mobility. Over the last four years, the Rekhi Innovation Challenge has provided more than $58,000 in support for 23 different student projects, attracting 267 unique donors.
For this year’s Rekhi Innovation Challenge, Blue Marble Security Enterprise is raising money to reach out to various community members and groups to increase interest in STEM fields among middle and high school students, particularly women.
BoardSport Technologies wants to develop a SmartBoard that will track snowboarders via GPS and REECO location to ensure a speedy rescue if caught in an avalanche or lost.
Velovations Enterprise is working with a local trails club to design and build a multi-purpose trail groomer with modular parts that can be swapped in the field to accommodate varying conditions.

Imagine deploying multiple undersea robots, all in touch and working together for months, even years, no matter how rigorous the mission, brutal the environment, or extreme the conditions.
It is possible, though not quite yet. “Limited energy resources and underwater communication are the biggest issues,” says Michigan Tech Researcher Nina Mahmoudian. Grants from a National Science Foundation CAREER Award and the Young Investigator Program from the Office of Naval Research are helping Mahmoudian solve those issues and pursue her ultimate goal: the persistent operation of undersea robots.
“Autonomous underwater vehicles (AUVs) are becoming more affordable and accessible to the research community,” she says. “But we still need multipurpose long-lasting AUVs that can adapt to new missions quickly and easily.”
Mahmoudian has already developed a fleet of low-cost, underwater gliders, ROUGHIEs, to do just that. Powered by batteries, they move together through the water simply by adjusting their buoyancy and weight. Each one weighs about 25 pounds. “ROUGHIE, by the way, stands for Research-Oriented Underwater Glider for Hands-on Investigative Engineering,” adds Mahmoudian.
“My most exciting observation was a Beluga mother and calf swimming together. It’s very similar to our recharge on-the-fly concept.”
“The ROUGHIE’s open control architecture can be rapidly modified to incorporate new control algorithms and integrate novel sensors,” she explains. “Components can be serviced, replaced, or rearranged in the field, so scientists can validate their research in situ.” Research in underwater control systems, communication and networking, and cooperative planning and navigation all stand to gain.
Mahmoudian observes Mother Nature to design robotic systems. “There is so much to learn,” she says. “My most exciting observation was a Beluga mother and calf swimming together. It’s very similar to our recharge on-the-fly concept. The technology is an early stage of development.”
Mahmoudian’s students apply and implement their algorithms on real robots and test them in real environments. They also give back to the community, by teaching middle school students how to design, build, and program their own low-cost underwater robots using a simple water bottle, called a GUPPIE.
“As a girl growing up, I first thought of becoming an architect,” says Mahmoudian. “Then, one day I visited an exhibition celebrating the 30th anniversary of space flight. That’s when I found my passion.” Mahmoudian went on to pursue aerospace engineering in Iran, and then graduate studies at Virginia Tech in the Department of Aerospace and Ocean Engineering. “Underwater gliders share the same physical concepts as airplanes and gliders, but deal with different fluid density and interactions,” she says.
Now at Michigan Tech, Mahmoudian’s work advances the abilities of unmanned robotic systems in the air, on land, and under sea. “Michigan Tech has easy access to the North Woods and Lake Superior—an ideal surrogate environment for testing the kind of autonomous systems needed for long term, challenging expeditions, like Arctic system exploration, or searching for signs of life on Europa, Jupiter’s moon.” She developed the Nonlinear and Autonomous Systems Laboratory (NAS Lab) in 2011 to address challenges that currently limit the use of autonomous vehicles in unknown, complex situations.
More than scientists and engineers, Mahmoudian wants simple, low-cost AUV’s to be available to anyone who may need one. “I envision communities in the Third World deploying low-cost AUVs to test and monitor the safety and quality of the water they use.”
Traditionally, in the electric power grid, generation follows electric power consumption, or demand. Instantaneous fluctuation in demand is primarily matched by controlling the power output of large generators.
As renewable energy sources including solar and wind power become more predominant, generation patterns have become more random. Finding the instantaneous power balance in the grid is imperative. Demand dispatch—the precise, direct control of customer loads—makes it possible.
Michigan Tech researcher Sumit Paudyal and his team are developing efficient real-time control algorithms to aggregate distributed energy resources, and coordinate them with the control of the underlying power grid infrastructure.
“Sensors, smart meters, smart appliances, home energy management systems, and other smart grid technologies facilitate the realization of the demand dispatch concept,” Paudyal explains.
“The use of demand dispatch has promising potential in the US, where it is estimated that one-fourth of the total demand for electricity could be dispatchable using smart grid technologies.”
Fourteen members and an adviser of the Michigan Tech Society of Women Engineers (SWE) Section attended the annual National SWE WE17 Conference from October 25-29, 2017, in Austin, Texas.
Participants attended sessions on a variety of topics, networked with company representatives at the Career Fair with over 300 STEM based companies and celebrated women in Engineering. Michigan Tech members volunteered at Invent It! Build It! (an outreach activity for middle and high school girls).
Gretchen Hein, SWE Section adviser and faculty in Engineering Fundamentals, presented on two topics: the results of a survey of SWE Women in Academia members and whether or not there are gender differences in student performance first-year engineering courses.
Whether it was learning about making SWE more inclusive to women of color or learning to be a grateful leader in the workforce, the conference provided members with a variety of opportunities. They eagerly anticipate another opportunity to grow, network and celebrate women in STEM at SWE WE18 Conference next fall in Minneapolis.

“Effect of Ionic Functional Groups on the Oxidation State and Interfacial Binding Property of Catechol-Based Adhesive” involves the study of marine mussels, which secrete catechol-containing adhesive proteins for underwater binding to surfaces like ship hulls and docks Catechol has been used by scientists and engineers around the world to design synthetic adhesives and coatings for wide ranges of applications. It can be used in tissue adhesive, tissue engineering scaffold, coating for preventing adhesion of bacteria, and so on.
It is shown, however, that in the presence of neutral to basic pH (for example, pH 7.4 in the body or pH 7.5-8.4 in the ocean), catechol oxidizes, leading to reduced adhesive strength. Mussels actually utilize multiple adhesive proteins with various ingenious designs to prevent catechol oxidation and to preserve strong adhesion. The adhesive proteins exhibit antioxidant properties, hydrophobicity for avoiding contact with basic sea water, and other methods in order to optimize adhesion.
We found that incorporation of acidic functional groups in the adhesive network can also prevent catechol oxidation, preserving strong adhesion, even up to a pH of 8.5. This is a much simpler approach than what the mussels employ and potentially easier for designing synthetic mimics of these adhesive proteins. This means that we will be able to design biomimetic adhesives for biomedical applications and underwater applications, which are the basic pH environments of interest.
More than 90 percent of US medical expenditures are spent on caring for patients who cope with chronic diseases. Some patients with congestive heart failure, for example, wear heart monitors 24/7 amid their daily activities.
Michigan Tech researcher Ye Sarah Sun develops new human interfaces for heart monitoring. “There’s been a real trade-off between comfort and signal accuracy, which can interfere with patient care and outcomes,” she says. Sun’s goal is to provide a reliable, personalized heart monitoring system that won’t disturb a patient’s life. “Patients need seamless monitoring while at home, and also while driving or at work,” she says.
Sun has designed a wearable, self-powered electrocardiogram (ECG) heart monitor. “ECG, a physiological signal, is the gold standard for diagnosis and treatment of heart disease, but it is a weak signal,” Sun explains. “When monitoring a weak signal, motion artifacts arise. Mitigating those artifacts is the greatest challenge.”
Sun and her research team have discovered and tapped into the mechanism underlying the phenomenon of motion artifacts. “We not only reduce the in uence of motion artifacts but also use it as a power resource,” she says.
Their new energy harvesting mechanism provides relatively high power density compared with traditional thermal and piezoelectric mechanisms. Sun and her team have greatly reduced the size and weight of an ECG monitoring device compared to a traditional battery-based solution. “The entire system is very small,” she says, about the size of a pack of gum.
“We not only reduce the influence of motion artifacts but also use it as a power resource.”
Unlike conventional clinical heart monitoring systems, Sun’s monitoring platform is able to acquire electrophysiological signals despite a gap of hair, cloth, or air between the skin and the electrodes. With no direct contact to the skin, users can avoid potential skin irritation and allergic contact dermatitis, too—something that could make long-term monitoring a lot more comfortable.
