LIFT Team Launches Fast Forge Project

LIFT building signDETROIT – Lightweight Innovations For Tomorrow (LIFT), a national manufacturing innovation institute operated by the American Lightweight Materials Innovation Institute, has joined with Michigan Upper Peninsula-based startup Loukus Technologies to launch a “Fast Forge” project exploring the use of ductile magnesium-based alloys for extrusions used in automotive, defense and consumer applications.

The project team, which includes LIFT, Loukus Technologies, Eck Industries and Michigan Technological University, aims to extrude magnesium alloys with high room temperature ductility (>25%). In turn, this process will lead to a roadmap of magnesium alloy design and development, and a materials properties database of how they can be used in future applications.

Biological sciences graduate student Chris Adams works in the GLRC fisheries lab with STEM intern Riley Stoppa.

A total of 13 high school students from throughout Michigan are participating in a 5-day internship at Michigan Tech July 15-19, 2019. Faculty and their graduate students voluntarily host the students in engaging research activities during the week. The faculty’s department, along with the College of Engineering and College of Sciences and Arts, together provide a $600 scholarship for the student that covers their transportation, lodging and meals.

The interns work with Michigan Tech faculty and graduate students in their research lab or doing field work outside. During the week, students tour the Michigan Tech campus and local area, ‘experience college living’ in a residence hall, and meet students from across Michigan and beyond!

In Dr. Parisa Abadi’s Mechanical Engineering Lab, students will be 3D printing nanomaterials. Dr. Tara Bal in the School of Forest Resources and Environmental Sciences (SFRES) will conduct invasive species monitoring and forest health assessments. Dr. Will Cantrell in Atmospheric Physics will have the intern investigating why some clouds rain, while others do not.

Dr. Daniel Dowden in the Department of Civil and Environmental Engineering (CEE) has his intern investigating which technologies will allow buildings to sustain minimal damage and be easily repairable after large earthquakes. Four faculty–Drs. Deering, Waite, Oommen, and Gierke in Geological and Mining Sciences and Engineering are providing a broad introduction of mapping geological features, conducting geophysical surveys, and working to construct a 3-D model of a geological feature. Dr. Casey Huckins and graduate student–Chris Adams in Biological Sciences–are monitoring Pilgrim River and measuring the results of a fish survey in the lab. Dr. Daisuke Minakata in CEE and Dr. Paul Doskey in SFRES, along with graduate students, are researching innovative drinking water and wastewater treatment technologies.

Dr. Michael Mullins in the Department of Chemical Engineering (ChE) has his intern researching ways to remove PFAs contaminants from water. Dr. Rebecca Ong in ChE has her two interns investigating biofuel production from native grasses. Dr. Chelsea Schelly in the Department of Social Sciences and Dr. Robert Handler in the Sustainable Future Institute are measuring food, energy, and water consumption in residential homes and looking for ways to reduce household resource consumption. Dr. Kuilin Zhang and his graduate student Qinjie Lyu in CEE have their intern studying traffic data collection, traffic signal timing, eco-driving, and using traffic simulation software.

The program is coordinated by the Michigan Tech Center for Science and Environmental Outreach, in partnership with Summer Youth Program who provides logistical support and supervises the students in the residence halls in the evening.

Funding for the program is received from the Michigan Tech College of Engineering, the College of Sciences and Arts, the Department of Civil and Environmental Engineering, the Department of Mechanical Engineering-Engineering Mechanics, the Department of Chemical Engineering, the School of Forest Resources and Environmental Science, the Department of Biological Sciences, the Great Lakes Research Center, Youth Programs, and an anonymous donor.

John Gierke (GMES/EPSSI) is Principal Investigator on a project that has received a $582,752 grant from the National Science Foundation. This is a potential three-year project.

Luke Bowman (GMES), Alex Mayer (CEE), Fengjing Liu (Forestry), and Angie Carter (SS) are Co-PI’s on the project titled “IRES Track III: Collaborative Research: Coupling Participatory and Hydrological Research for Adapting to Extreme Hydrometeorological Events in Agricultural Communities, El Salvador.”

Extract

In this project, graduate students from US universities obtain international research experience in social and hydrological sciences while working on a scientific problem with real-world implications.

Changes in climate cause communities to adapt to enhance resiliency and foster practices that are more appropriate for new conditions. In regions where dry seasons are increasingly long, the shorter rainy seasons experience more severe storms.

Rural and agricultural communities are especially vulnerable to new seasonal conditions and their resources for adaptation are limited.

The Dry Corridor of Central America (spanning parts of El Salvador, Guatemala, Honduras, and Nicaragua) is an important region for agriculture and needs adaptation strategies. The project location is ideal because of its many-decades history of changing climate.

The project participants work with local farmers and agricultural stakeholders to gain experience in adapting to climate change. The interdisciplinary scientists and development professionals work together in participatory research in communities experiencing water scarcity and extreme rainfall events.
