LONGVIEW – LeTourneau University has been awarded a $250,000 grant from the W. M. Keck Foundation. The funds will be used for the purchase and installation of a new scanning electron microscope (SEM) in the Kielhorn Welding and Materials Joining Engineering Laboratory at the school. A news release from the school says the new equipment will assist in modernizing existing materials joining engineering courses focused on welding metallurgy. It will also be used in biology and chemistry lab courses that will be able to add modules to introduce undergraduate students to SEM imaging. The new SEM is expected to be purchased and installed this spring and ready for use by summer, with undergraduate students across campus expected to be using it for a variety of different projects starting in the fall.
