One of only three Category 5 hurricanes to hit the U.S. since records have been kept, Hurricane Andrew caused wind speeds upwards of 175 mph. One of the costliest hurricanes in U.S. history, Andrew killed 43 people and caused $30.5 billion in damage.

One of only three Category 5 hurricanes to hit the U.S. since records have been kept, Hurricane Andrew caused wind speeds upwards of 175 mph. One of the costliest hurricanes in U.S. history, Andrew killed 43 people and caused $30.5 billion in damage.

Wind damage and injuries following Hurricane Andrew in the 1990s drew Lokesh Dharani to glass research. 

Dharani, Curators’ Professor of mechanical and aerospace engineering, was one of several researchers at S&T to receive National Science Foundation funding to develop a new approach to making a stronger laminated architectural glass.

The laminated glass consists of two soda lime silicate glass layers that sandwich a layer of polymer, like poly vinyl butyral (PVB).

“Roof gravel, asphalt pieces flying from the roof, shingles, windborne pieces of lumber — these are all considered ‘missile impact’ on glass,” he says. “Windborne debris combined with strong winds is the main reason for failure of architectural glazing.”

Upon impact, monolithic (single-pane) glass breaks into dangerous shards, and causes a breach in a building’s protective barrier. But laminated glazing, Dharani says, holds the broken pieces of glass in its interlayer, which stays in the frame and maintains the building’s structural integrity.

“It’s called sacrificial ply design,” he says. “We intentionally sacrifice the outer layer, allow it to fracture, crack and absorb all the energy, but the inside layer stays intact.”

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 […]
