Missouri S&T researcher tracks subsurface water flow
By combining computational mathematics and several engineering disciplines, a Missouri University of Science and Technology researcher hopes to consistently predict the underground flow of water through porous terrain with large fractures, channels or conduits.

ROLLA, Mo. — Batteries are everyday objects people don’t think about — until they run out of juice. That’s especially true the more ubiquitous an object is, such as laptop computers and cellphones that need to have their batteries charged seemingly every day.
But Missouri University of Science and Technology researchers are working to solve the problem of short-life of lithium-ion batteries like those used in laptops and cellphones, making them reliable and longer-lasting using a thin-film coating technique called atomic layer deposition (ALD). Their paper, titled “Employing Synergetic Effect of Doping and Thin-Film Coating to Boost the Performance of Lithium-Ion Battery Cathode Particles,” is being published today, Wednesday, May 4, in Scientific Reports, a Nature publishing group journal.

Researching ways to cure cancer and neurodegenerative diseases in the lab is painstaking, time-consuming and expensive. But a Missouri University of Science and Technology professor is using computer modeling to test drug therapies that one day could lead to cures for these conditions that kill millions each year.
Dr. Dipak Barua, assistant professor of chemical and biochemical engineering at Missouri S&T, is the principal investigator on a project funded with a Department of Energy grant for $112,377 on “countering pathogen interfaces with human defenses.”
“We use math and computational modeling as a tool to understand the mechanisms in cells, and we develop computational and mathematical models that make predictions” about what will happen with different therapies, Barua says.

Studying blood for the greater good
Elizabeth Bowles, a Ph.D. student in chemistry at Missouri S&T, has had a rather unconventional goal for the past several years: improve the care of patients with conditions like diabetes or pulmonary arterial hypertension by reducing severe adverse side effects of pharmaceuticals through a new and innovative drug delivery system. Bowles first started tackling her […]

Missouri University of Science and Technology researchers have developed a real-time, portable and 3-D microwave video camera prototype.
The Missouri S&T team has developed a microwave 3-D video camera that can be used for industrial inspection applications, security screening — and might even one day be used by first responders. Dr. Mohammad Tayeb Ghasr, assistant research professor at Missouri S&T, and Dr. Reza Zoughi, the Schlumberger Distinguished Professor of Electrical Engineering at Missouri S&T, are the lead researchers on the project.

From hip and knee joints to complex fuel injectors, metal additive manufacturing — an advanced form of 3-D printing involving lasers and powder-based metals — can produce components that traditional machining processes cannot match in time-to-part, geometric complexity and manufacturing cost.
A team of Missouri University of Science and Technology researchers is collaborating with Honeywell Federal Manufacturing & Technologies in Kansas City, Missouri on a five-year project to perform material analysis for the selective laser melting (SLM) process in metal powder bed. Dr. Ming Leu, Keith and Pat Bailey Missouri Distinguished Professor of Integrated Product Manufacturing and the director of the Intelligent Systems Center at Missouri S&T, is leading a team of seven other Missouri S&T professors on the project.

A Missouri University of Science and Technology researcher is studying how to make concrete that can be placed without a lot of human intervention, and that can be poured in hard-to-reach places where people can’t easily manipulate it.
Dr. Dimitri Feys, assistant professor of civil, architectural and environmental engineering at Missouri S&T, is working with self-consolidating concrete to produce beams that can be used to construct bridges, parking garages or other construction. Self-consolidating concrete is a type that flows easily in concrete forms or molds.
“The main use of this concrete is in Japan and Europe — 100 percent of the pre-cast industry in Denmark uses this type — and it slowly is making its way in the U.S. market,” he says.
But there are challenges, Feys says.

S&T technique to detect breast cancer moving from lab to commercialization
Cancer screening could soon be as simple as giving a urine sample using a patented device developed by a Missouri University of Science and Technology researcher. This week, Wyoming-based Cancer.im Inc., a Viratech Corp. company (Symbol: VIRA) and social network for cancer patients, survivors and caretakers, announced an agreement with Missouri S&T to commercialize the device.

New mathematical model illustrates link between energy use and aging
Why does a Great Dane have a shorter lifespan than a pug? The answer lies in a complex relationship between energy usage and lifespan. That relationship is quickly being unraveled through the use of numerical modeling by a researcher at Missouri University of Science and Technology.
