Louisiana Accelerator Center: Research for a Reason
The UL Lafayette Louisiana Accelerator Center brings together faculty members, researchers, graduate students and industry professionals to Ӱרtackle problems which are relevant to society,Ӱר says center director Dr. Harry J. Whitlow.
And that research affects everything from our teeth to our waterways to space exploration.
ӰרWe get to work with a lot of very-top scientists, and thatӰרs stimulating because we can help them in their work,Ӱר he says, Ӱרand that helps us because it means we have interesting topics to work on Ӱר and that these topics are relevant.
ӰרThatӰרs what I get a kick out of: doing things that are relevant. I care about the impact.Ӱר
Relevant research Ӱר with myriad applications.
Electronics in space
One of the most impressive instruments at the Louisiana Accelerator Center is the ultra-low fluence irradiation beamline end station, which was built by Jay Dias, Ӱר18, in the Master of Science in physics program. ItӰרs used to simulate proton irradiation in space, which is the dominant form of radiation coming from the sun and other far-off cosmic sources.
Massive proton ejections accompany solar flares, causing radiation levels to spike significantly. By recreating the radiation and simulating the effects of radiation on satellite components, electronics, and lenses, they can determine if the components would degrade or change as a result. With these same methods, they can also simulate the effects of radiation levels on cells, helping to determine how organisms and even humans would be affected.
Airbag sensors
Dr. WhitlowӰרs area of expertise is ion-matter reactions and their applications. At the LAC, he uses ions to transfer energy to different materials, which change them. In that vein, he is working with graduate student Kyle Coutee in the physics masterӰרs program on the potential for a novel type of material electrets applications in sensors. More specifically, these can be used in airbag sensors for cars Ӱר the sensor measures the sudden change of speed in the car and then signals that the airbags should inflate.
Administering insulin
at the Louisiana Accelerator Center is also exploring how electrets made with ion beams can be used for energy harvesting that could be used to help diabetes patients. An implant or wearable device can convert body movement into electrical energy, which can then measure blood sugar levels and administer a tailored dose of insulin, which gives the patient much more control and stability than conventional methods.
Cavity fillings & wheel bearings
At the recent International Conference on Ion Beam Analysis, a team led by Dr. Wanwisa Sudprasert from ThailandӰרs Kasetsart Ӱר that also included Dr. Whitlow and UL Lafayette physics masterӰרs student Henry Odeogu, won an award for the best science work for their research on mercury pathways in dental amalgam, which is used to fill cavities. Through their work, this international team of researchers disproved their initial hypothesis when analyzing the distribution of mercury where the amalgam and enamel meet and at the biting surface.
ӰרItӰרs quite interesting because it was a process that is also problematic for the watchmaking industry, of all things,Ӱר Dr. Whitlow explains. ӰרAlso in the 1940s and Ӱר50s, the Ford automotive company was transporting cars by rail Ӱר and the bearings on the cars were rubbing on just one place as they were transported. It led to the premature failure of the wheel bearings, so itӰרs a problem on a large scale, but it was also actually happening on the biting surface of the amalgam.Ӱר
Lead and other toxin levels in water
Apple snails, a non-indigenous invasive species in Louisiana, hold the potential to be environmental sensors in Louisiana waterways. The snailsӰר shells absorb toxins and other materials from their environment, including lead. As researchers at the Louisiana Accelerator Center and the analyze the uptake of lead in these apple snailsӰר shells, theyӰרre exploring the possibility of using them to measure the quality of the water where they reside.
Upcoming research for a reason
The Louisiana Accelerator Center recently received a grant to build a new instrument for organic molecule imaging, which will be used to image specific biological molecules. When working with Ӱר biologists, they will be able to look at signal substances in neurological cells, which affect behavior.
Dr. Whitlow is constantly looking for more collaborators and is working with biologists, geologists, physicists and radiation scientists at the Louisiana Accelerator Center. And heӰרs especially committed to including graduate students as collaborators.
ӰרI get a sense of creativity from working with grad students,Ӱר he says. He prioritizes the Ӱרhands-on taskӰר of preparing grad students to do research Ӱר Ӱרhow to set up questions, to set up tests to test their hypothesis, and then how to interpret the results and most importantly how to present it.Ӱר
ӰרOur philosophy is that weӰרre here to promote the research within the Ӱר and also the surrounding companies and environment,Ӱר says Dr. Whitlow.
ӰרThis is why itӰרs important to meet with the other scientists and find out what theyӰרre interested in Ӱר because sometimes they could have a solution to our problems and we could have a solution to their problems. By this manner, we can drive science forward. We are very much in a cross-disciplinary science, and thatӰרs where the great discoveries are made.Ӱר
