William C. and Ruth Ann Dewel Microscopy Facility

Welcome to William C. and Ruth Ann Dewel - College of Arts & Sciences (Dewel-CAS) Microscopy Facility at Appalachian State University (ASU). We provide light microscopy, laser scanning confocal microscopy, and electron microscopy equipment and technical support to ASU and Appalachian Communities.

 

Confocal Z-Series: reveals a punctate expression pattern of Meis gene in the trunk along the spine and neural tube in Zebrafish. The video is produced by graduate student Laiton Steele in Dr. Ted Zerucha‚Äôs lab.

TEM Tilt Series: shows inner membranes of a chloroplast in Arabidopsis. The video is produced by Dr. Guichuan Hou.

News & Announcements

Graduate Student News

Biology graduate student Mara Cloutier in Dr. Suzanna Brauer's lab studies manganese-oxidizing bacteria and fungi using molecular techniques and SEM-EDS. She has been awarded several grants for her research and soon she will start her PhD project in Penn State - Congratulations to Mara!

Future Scientists

DukeTIP students visited the microscopy facility June 12th. They watched demos with diffferent microscopes and asked many interesting questions.

Geology Research Highlight

Hugh Harper and Dr. Ellen Cowan (Geology Department) are imaging the surface texture of quartz sand grains with SEM and EDS to determine the glacial history of iceberg rafted grains recovered during IODP drilling from the Gulf of Alaska. The outline of each grain is also used to calculate grain roughness using Fourier analysis.
