Termite Mounds Hide Secrets to Sustainable Buildings of the Future

Andrea Surovek, Ph.D., a research scientist from SD Mines’ Department of Mechanical Engineering, standing next to a termite mound in Namibia.

South Dakota School of Mines & Technology has been awarded $475,000 from the National Science Foundation to study how termites construct mounds with the idea that humans might one day adapt the energy-efficient homebuilding techniques of the insects. The award is a follow-up to a previous grant by NSF of $300,000.

Mines faculty researchers spent time in the African country of Namibia to study the shape and function of termite mounds. The mounds are resilient and naturally energy efficient. Their intricate interior designs provide ventilation and temperature regulation throughout what can easily be a 15-foot-tall home for a single colony of 2 million termites. 

“An understanding of the natural processes involved in termite mound construction and function can be adapted to inform engineering applications related to the construction of man-made structures that require zero or minimal energy inputs,” said the NSF award letter.

Co-principal investigator Andrea Surovek, Ph.D., a research scientist from SD Mines’ Department of Mechanical Engineering, has lead research that examined hundreds of slices of a termite mound and has developed three-dimensional models of numerous mounds using ...

Composite Bridge Winners Use Lightweight, Strong, Inexpensive Material Developed at SD Mines

South Dakota School of Mines and Technology students took home second place in the Society for the Advancement of Material and Process Engineering (SAMPE) 2018 Student Bridge Contest, by designing a bridge weighing just 12.5 ounces that can carry a 2,000-pound load.

The competition, held in Long Beach, Calif., pitted SD Mines researchers against 70 teams from 30 universities from around the world. Teams were tasked to design, build and test a 24-inch-long structural composite bridge using fiber reinforced plastics and high-performance materials. The annual event challenges teams to make bridges that carry a specified load while also being as lightweight as possible. The Mines bridge placed second in the inaugural year of the sandwich beam category at SAMPE’s bridge contest.

“The SAMPE bridge competition is a fantastic opportunity for students to develop some hands-on composite fabrication skills and to see how the process side of composites engineering truly impacts their final performance,” says Eric Schmid, SD Mines bridge team member and SAMPE North America Young Professionals committee chair. “SAMPE provides an excellent platform for students to demonstrate their capabilities, and the chance to attend the SAMPE conference and bridge competition really gives students a great view of how important compo...

Ballooning in the Shadow of the Moon

This image, courtesy of the South Dakota Solar Eclipse Balloon Team, shows the moon's shadow crossing the Nebraska Panhandle during the Great American Eclipse of 2017.

At 10:35 a.m. on August 21, 2017, in a field in front of a small Nebraska Panhandle farmhouse, a team consisting of SD Mines students, Black Hills area high school students, teachers and community members, meticulously followed a set of steps they had practiced many times before. Payloads were carefully secured, batteries checked, and scientific instruments turned on and tested. Soon, helium was coursing through a hose from tanks in the back of a pickup truck into an eight-foot-tall balloon laid out on the soft grass.

Above the desolate cornfields and sandhills of northwestern Nebraska the moon was starting its path across the sun–the arc of its shadow racing across the country toward this team. The Great American Eclipse was underway.

The South Dakota Solar Eclipse Balloon Team had been working for two years to prepare for this one sliver in time. Their goal—to launch this balloon at the exact moment to loft the payload to an altitude of about 100,000 feet, under the moon’s shadow, during two minutes of totality. On board were video cameras, a radiation detector, GPS, and other scientific experiments. This project aimed to capture images and data from the eclipse. The radiation detector would help measure the flux of cosmic rays in the upper atmosphere as the moon obscured the sun. The video cameras would capture the circle of the moon’s shadow on the earth. The team designed and built some of ...

Growing Copper Deep Underground: SD Mines Plays Integral Role in Successful MAJORANA DEMONSTRATOR Experiment

Much of the experiment’s copper is processed underground to remove both natural radioactivity (such as thorium and uranium) and radioactivity generated above ground when cosmic rays strike the copper. Electroforming relies on an electroplating process that over several years forms the world’s purest copper stock. Ultrapure copper is dissolved in acid and electrolytically forms a centimeter-thick plate around a cylindrical stainless-steel mandrel. Any radioactive impurities are left behind in the acid. Here collaborator Cabot-Ann Christofferson of the South Dakota School of Mines & Technology measures the thickness of copper pulled from an electroforming bath.

The collaborators working on the MAJORANA DEMONSTRATOR have published a study in the journal Physical Review Letters showing the success of the experiment housed in the Sanford Underground Research Facility (SURF). The success of the MAJORANA DEMONSTRATOR opens the door for the next phase of the experiment and sets the stage for a breakthrough in the fundamental understanding of matter in the universe. 

The experiment, led by the Department of Energy’s Oak Ridge National Laboratory, involves 129 researchers from 27 institutions and six nations. The South Dakota School of Mines & Technology was an integral part in facilitating the underground laboratory space at SURF and helped lead the effort to build the ultra-pure components needed to construct a successful experiment. 

“The goal was to demonstrate the feasibility and capability to build a larger one-ton experiment,”  says Cabot-Ann Christofferson, the Liaison and a Task Leader within the  MAJORANA Collaboration at the Sanford Underground Lab and an...

South Dakota Space Grant Awards $176,000 in NASA Funding to SD Mines and Five South Dakota Institutions

A team of Mines students working on a component of the National Solar Eclipse Balloon Project. This is one example of a research funded by the South Dakota Space Grant Consortium headquartered at Mines.

The South Dakota Space Grant Consortium (SDSGC) has provided nine awards totaling approximately $176,000 in NASA funding to SD Mines and five affiliate members of the Consortium.

The Space Grant Consortium, headquartered at the South Dakota School of Mines & Technology, is a statewide network of 20 member organizations from education, industry and government. As the link between NASA and the citizens of South Dakota, the Consortium’s mission is to instill the spirit of exploration and discovery in students, educators and the general public, with a special focus on the fields of science, technology, engineering and math that are essential for the development of the nation’s workforce.

One grant of $17,100 was awarded directly to a Mines student, Kari Pulli, a junior in mechanical engineering, as a scholarship for a project titled “Student CO-OP for Aerospace and High-Altitude Technology Development.”  Pulli was selected by officials at Raven-Aerostar for an eight-month student internship at its Sioux Falls facility. This is on top of a previously announced SDSGC grant of $25,000 to SD Mines for a project titled: “Computational Astronomy for Teachers and Their Students.

In total, nine winning projects were competitively selected from among 15 proposals submitted under the SDSGC’s FY2016 Project Innovati...
