Volcano warning

Much like National Weather Service sirens signal impending severe weather, so too may a similar system warn us before earthquakes strike or volcanoes erupt.

volcanoUsing 1,700 seismographs spread across the lower 48 states, two S&T geophysicists are creating a sort of CT scan of the North American plate, which has been moving southwest at a rate of about an inch a year.

The shift is a continuation of the breaking of the giant supercontinent Pangea 200 million years ago, says Kelly Liu, professor of geophysics at Missouri S&T. As the plate moves, it creates earthquakes and volcanic hot spots, huge mountain chains and gigantic ocean basins.

With funding from the National Science Foundation, Liu and geophysics professor Stephen Gao are looking for azimuthal anisotropy along the path of a seismic wave. Seismic azimuthal anisotropy measurement is a powerful way to image the earth’s internal structural fabric. Their work could lay the foundation for predicting earthquakes and volcanic eruptions.

Honoring new academy members

In October, 12 alumni and friends were inducted into Missouri S&T academies. Academy membership recognizes careers of distinction and invites members to share their wisdom, influence and resources with faculty and students. Some academies hold induction ceremonies in the fall, others in the spring.

Boosting cyber-physical security

A wide array of complex systems that rely on computers — from public water supply systems and electric grids to chemical plants and self-driving vehicles — increasingly come under not just digital but physical attacks. Bruce McMillin, professor and interim chair of computer science at Missouri S&T, is looking to change that by developing stronger safeguards […]

MXene discovery could improve energy storage

In spite of their diminutive size, 2-D titanium carbide materials known as MXenes are “quite reactive” to water, a discovery S&T researchers say could have implications for energy storage and harvesting applications such as batteries, supercapacitors and beyond. Their findings were published in 2018 in the American Chemical Society journal Inorganic Chemistry.

A faster charge for electric vehicles

One drawback of electric vehicles (EVs) is the time it takes to charge them. But what if you could plug in your EV and fully charge it as quickly as it takes to fill up a conventional car with gasoline? Missouri S&T researchers, in collaboration with three private companies, are working to make speedy charging […]
