By some estimates, 18 million people die each year from sepsis triggered by endotoxins – fragments of the outer membranes of bacteria. A biochemical engineer at Missouri S&T has patented a method of removing these harmful elements from water and also from pharmaceutical formulations. Her goal: improve drug safety and increase access to clean drinking water in the developing world.
The technique, as outlined in a July 2016 article in the journal Nanotechnology, involves a one-step phase separation method, using a syringe pump, to synthesize the nanoparticles. Those polymer nanoparticles have a high endotoxin removal efficiency of nearly 1 million endotoxin units per milliliter of water, using only a few micrograms of the material.

Scientists at Missouri S&T are drawing inspiration from toy building blocks to create fixed molecular units used to accelerate the material discovery process known as rational design. They’ll use these “molecular blocks” to discover highly ionic conductive materials that could be used to make today’s much sought after all-solid-state lithium batteries.

Researchers at Missouri S&T have discovered a new way to harness the potential of a type of spontaneously oxidized MXene thin films, to create nanocomposites that could sense both light and the environment. Previously, such spontaneous oxidation was considered detrimental because it degrades the MXene structure. The research is published in the June 2018 issue of ACS Nano, one of Google Scholar’s top-rated, peer-reviewed scientific journals.

He’s driven the backroads with some of the biggest names in rock and roll, from Def Leppard and KISS to John Denver and the Eurythmics, hauling both gear and performers as a truck- and bus-driving roadie. Yet despite his many brushes with fame, what gets Mike Lusher most excited these days is his research into an unassuming desert shrub that some predict will revolutionize the rubber industry. A fascination with the guayule (why-YOO-lee) plant that began a dozen years ago while watching an episode of The History Channel show “Modern Marvels” has culminated in a Ph.D. in civil engineering for the 64-year-old grandfather, who received his diploma at May 12 commencement.

Missouri S&T doctoral student works to improve drug safety, efficacy with new chiral templates

In the early 1960s, the Thalidomide drug scare caused thousands of worldwide infant deaths and birth defects from a morning sickness medicine for expectant mothers. The disaster transformed drug regulation systems, and changed the pharmaceutical industry’s understanding of chiral properties: the notion that molecules with otherwise identical properties are in fact mirror images, like your right and left hands. Missouri S&T materials science and engineering doctoral student Meagan Kelso wasn’t even close to being born when the chiral consequences of Thalidomide first became apparent nearly 60 years ago. But the drug industry’s continued efforts to fine-tune how it first identifies and then separates chiral compounds is driving the native Texan’s Ph.D. research.
