S&T researcher tests fly ash for stronger concrete

Portland cement has been around for more than 250 years as the binding material for concrete, mortar and stucco, but a Missouri University of Science and Technology researcher is studying ways to make concrete without the traditional material.

Dr. Mohamed ElGawady, associate professor of civil, architectural and environmental engineering at Missouri S&T, is testing mixtures of concrete made with fly ash that can be more durable, strong and resilient than concrete using ordinary Portland cement (OPC). [Read more…]

Missouri S&T chapter of Engineers Without Borders receives $750,000 in funding

From clean drinking water to flood control, Missouri University of Science and Technology’s Engineers Without Borders projects are changing lives in Central and South America. Now two major donors have stepped forward to provide $750,000 in funding for EWB – a $500,000 challenge grant from the Houston-based Montana Cahill Foundation and a $250,000 gift from Missouri S&T graduate David Heikkinen and his wife, Ann.

“EWB students are a different breed and we are lucky to have them,” says Duane Montana, a Montana Cahill Foundation director and retired executive with Brown & Root who earned a bachelor of science degree in civil engineering from Missouri S&T. “EWB students represent something of our higher nature and better selves. They make a commitment, often over multiple years, that goes beyond the classroom. It is a commitment to a community to provide its people with a basic life necessity: clean water.” [Read more…]

Ph.D. student not slowing down after 30-year career as federal government scientist

“The trouble with retirement is you never get a day off.”

Former University of Texas men’s basketball coach Abe Lemons popularized that one-liner in a long-ago interview. Missouri S&T doctoral student Ken Boyko embraces that sentiment to a degree few can hope to match.

At 65, Boyko is preparing to complete a Ph.D. in geological engineering, perhaps as soon as this fall. His research focuses on how LIDAR (light detection and ranging) scanners can be used to “see through” vegetation that might otherwise prevent detection of potential falling rock. The research could enhance safety along highways and bridges and also involved a project for the U.S. Navy, which wants to use the technology as a navigational aid for self-driving off-road vehicles.

S&T researcher studies next generation phones, cars

In 10 years, your cellphone won’t look anything like it does today — at least on the inside. The phones, with 5G technology, will be 10 times faster than they are today. And self-driving cars won’t be a novelty, they will be part of your daily commute.

A Missouri University of Science and Technology researcher is working to make those goals a reality — a safe reality — by deciphering and solving the problems of electromagnetic interference inherent in the systems. Dr. Jun Fan, professor of electrical and computer engineering at Missouri S&T, is using a Google grant to provide real-world solutions. [Read more…]

African Ph.D. student works on small-scale mining safety in Ghana

Ph.D. student Kenneth Bansah has formed a nonprofit organization in his native Ghana to improve working conditions for female artisanal miners who do so as means to survival.

Two boys swim in the Tano River near Ghana’s western border with Ivory Coast. Contamination from artisanal mining has rendered the river’s water unfit for human consumption. Kenneth Bansah.

As a doctoral student in mining engineering, Kenneth Bansah works, learns and lives nearly 10,000 miles from his boyhood home of Tarkwa, Ghana, a gold mining hub in western Africa.

But even as he fine-tunes his dissertation on mitigating sinkhole hazards and other karst formations − and takes care of three children ages four and under while his wife completes her own graduate studies in Michigan – the subsistence gold miners of Ghana are never far from Bansah’s mind.

Or his heart.

Missouri S&T research team helps Boeing set up nondestructive evaluation laboratory

Researchers at Missouri University of Science and Technology recently worked with The Boeing Company to establish a new nondestructive evaluation laboratory that uses millimeter wave technology to improve the detection of potential flaws in coatings, surfaces and materials. [Read more…]

Smith elected treasurer of national chemical engineering organization

Dr. Joseph Smith, the Wayne and Gayle Laufer Chair of Energy at Missouri University of Science and Technology, has been elected treasurer of the American Institute of Chemical Engineers (AIChE).

As an officer, Smith will help guide the national organization that has over 50,000 worldwide members. In December, he finished a three-year term as a member of AIChE’s board of directors before being picked to be treasurer, where he will serve as chair of the finance committee and as a member of the executive committee.

Robotics expert to speak about robots that teach

There are robots to sweep your floors and robots to sort packages at warehouse giants. But a Yale University professor says robots can do much more than just interact with people on a physical level — they can interact more personally, providing cues to guide social behavior.

Dr. Brian Scassellati, professor of computer science, cognitive science and mechanical engineering at Yale and direc¬tor of the National Science Foundation Expedition on Socially Assistive Robotics, will visit Missouri University of Science and Technology on Feb. 6 to deliver a lecture titled “Building Robots That Teach.” [Read more…]
