South Dakota Mines has created a new multidisciplinary Center for Sustainable Solutions. The center will be a hub for research and development around sustainability including water quality, emerging contaminants, agriculture, infrastructure, carbon capture, biofuels, bioplastics, environmental stewardship and more.

“As society faces increasingly complex problems, providing sustainable solutions requires integrative partnerships and approaches that build convergence of many disciplines with research and support for stakeholders at all levels,” says Lisa Kunza, Ph.D., an associate professor in the Department of Chemistry, Biology and Health Sciences and the director of the new center at Mines.

In the last five years leading up to establishing the Center for Sustainable Solutions, there have been nearly 50 faculty and researchers from eight departments on campus participating in the efforts. “As an institution of higher education, it is imperative to have many graduate and undergraduate students trained in the collaborative environment that the Center for Sustainable Solutions provides while tying the innovative efforts to support the needs of the people,” says Kunza.

The center will help serve the needs of a wide range of partners, from assisting the Department of Defense (DoD) in mitigating emerging ...

Wildfire smoke may have a significant impact on the efficiency of solar panels and the overall effort to transition nation’s energy production from fossil fuels to more solar based systems, according to research published by Long Zhao, Ph.D., an assistant professor in the Department of Electrical Engineering and Computer Science at South Dakota Mines and director of the Smart Grid and Energy Research Lab at South Dakota Mines.

Zhao’s work, conducted over the last two years when wildfire smoke blanketed parts of the American West, shows that widespread smoke can reduce the output of individual solar panels by nearly 50% -- even on days when smoke is present at high altitudes and air quality near the ground is not significantly impacted.

“It depends on where you are,” says Zhao. It makes sense that solar energy production is negatively impacted on very smoky days, but Zhao’s team was surprised to see reductions in solar energy output when wildfire smoke was aloft higher in atmosphere. “This makes it harder to quantify days when smoke will impact solar energy production based on air quality monitoring systems we have in place,” he says.  His work will be published in the Journal IEEE Transactions on Industry Applications.

Unlike passing clouds, that can reduce solar energy generation for a short duration, wildfire smoke can...

South Dakota Mines and the Universidad Peruana de Ciencias Aplicadas in Lima, Peru, (UPC Peru) were awarded a grant from the 100,000 Strong in the Americas Innovation Fund to build a partnership that includes a student exchange that builds technical, intercultural and soft-skills training that are needed to improve water quality in Peru.

This program will increase student and faculty collaboration, mobility and cross-cultural skills in the U.S. and Peru. It will also hone student skills via a water sanitation project for families who lack water services in the Lima district of Villa María del Triunfo, Peru.

Capstone design student teams and faculty from both universities will work together virtually and in-person on implementation of a fog catcher system that collects water from the air to be used for domestic purposes, irrigation of orchards and the implementation of a waste-water treatment system to be re-used for irrigation. At Mines, multidisciplinary teams of students from chemical engineering, civil and environmental engineering and other departments will be invol...

South Dakota Mines has received a new $750,000 NASA EPSCoR grant to fund research into the next generation of lithium-sulfur batteries for use in space technology. The grant comes following a breakthrough on campus into a new polymer-biocarbon cathode coating made from corn stalk residues that stabilizes next-generation battery chemistry to nearly double the charging capacity of current technology.

A press release from NASA on this research states, “Improving the power capacity and life of batteries could help NASA power rockets, spacecraft, and habitats on the Moon, and eventually, Mars.”

The breakthrough began with the work of Rajesh Shende, Ph.D., on finding new uses for biorefinery waste leftover from the bioproc...

South Dakota Mines is installing a new Scanning Electron Microscope (SEM) in the university’s Engineering and Mining Experiment Station (EMES) thanks to a $1.3 million grant from the National Science Foundation. The new microscope is just one of many state-of-the-art scientific instruments inside the recently expanded EMES which serves high-tech industry alongside university researchers across the state.

The powerful SEM microscope is a centerpiece of the EMES. It allows researchers to perform high resolution imaging, chemical analysis and sample manipulation for various materials at scales ranging down to 100,000 times smaller than the width of a human hair. The new microscope is a critical resource for a wide variety of research across multiple disciplines.

“The SEM is the most heavily used research instrument on campus,” says Grant Crawford, Ph.D., the director of the Arbegast Materials Processing and Joining Laboratory at Mines and an associate professor in the Department of Materials and Metallurgical Engineering.

The new SEM is equipped with a focused ion beam that dramatically expands its capability over the old system. The ion beam allows researchers to extract samples for separate analysis and cr...

The Engineering and Mining Experiment Station (EMES) at South Dakota Mines has begun overseeing the operation and maintenance of instrumentation within the Shimadzu Environmental Research Laboratory (SERL).

The EMES was founded on the Mines campus in 1903 with a mission to serve mining industry research. Today the mission has expanded to include a much broader range of academic and industry needs with a wide array of scientific equipment that is utilized by industry professionals and university researchers across the region. The EMES has seen equipment investments by the South Dakota Board of Regents and the National Science Foundation totaling more than $2.8 million since 2011. The EMES website lists the range of scientific equipment available for academic research and industry use including the Shimadzu instrumentation.

The SERL was established in 2015 in partnership with Shimadzu Scientific Instruments by Lisa Kunza. Ph.D., associate professor in the Department of Chemistry Biology and Health Sciences at Mines. The SERL is a multidisciplinary research facility that contains a suite of state-of-the-art instrumentation with a focus on environmental applications. SERL instruments enable the chemical characterization of a wide range of sample types including natural waters, biological materials, roc...

“Flying 700 miles per hour through a tube using magnets and sunlight isn’t a dream.”

The baritone narrator in a video describing the proposed Great Lakes Hyperloop makes the case that a twenty-eight minute commute over the 343 miles that separate Cleveland from Chicago is a near-term reality.

For Chuck Michael (CE 77), hyperloop is the future of transportation. “This is a game-changing technology with a huge public benefit,” he says. “You could work in downtown Chicago and live in Cleveland and get to work faster than sitting on the freeway from the Chicago suburbs.”

The hyperloop concept involves a magnetically levitated capsule that is propelled through a vacuum tunnel at velocities approaching the speed of sound using renewable wind and solar energy. Michael is the head of US feasibility studies and regulatory advisor for the company Hyperloop Transportation Technologies based in Los Angeles. “We use a proprietary passive magnetic levitation system, developed at Lawrence Livermore National Lab,” Michael says. A small forward motion on the permanent magnetic array creates a field that aids both propulsion and levitation.

“We can levitate twenty tons at walking speed,” Michael says. A "re...

Satellites are often thought of as huge complicated devices that are deployed on the tops of rockets or in space shuttle payloads. They hold massive telescopes, sophisticated weather monitoring devices or global positioning system components.  The price tag for large satellites is often measured in billions, not millions. 

CubeSats are different. They’re smaller - think volleyball, not Volkswagen - and they’re cheaper.  NASA describes a CubeSat as a “low-cost pathway to conduct scientific investigations and technology demonstrations in space, thus enabling students, teachers, and faculty to obtain hands-on flight hardware development experience.”  The cost of these nanosatellites is small enough to fit into many school budgets. CubeSats are built to investigate areas of scientific interest such as the earth’s atmosphere, space weather, in-space propulsion, radiation testing, and communication, to name a few. Satellites are selected based on their investigations and how they align with NASA’s strategic plan.

One area of CubeSat research at the South Dakota School of Mines & Technology is to expand from one small satellite to a swarm of small satellites working together. This has the potential to multiply the impact and effectiveness of a single CubeSat.
