MICRON SCHOOL OF MATERIALS SCIENCE AND ENGINEERING (MSMSE) #52 – NANOINDENTATION OF THIN FILMS: FORCE-DISPLACEMENT TO STRESS-STRAIN DEPARTMENT: Micron School of Material Science and Engineering TEAM MEMBERS: Ashton Enrriques Bette Gougar Carmen Wu CLIENT: Micron Technology PROJECT ADVISORS: Dr. Harold Ackler Dr. Paul Davis MENTORS: Dr. Paul Davis Dr. Steve Hues Thiagarajan Raman Derik Rudd Dr. Guohua Wei
Nanoindentation is a mechanical indentation testing tool that is performed on small areas. This can provide information such as the hardness, young’s modulus, and other elastic properties of microscopic materials. However, nanoindentation does not provide information on materials as it transitions from elastic deformation to plastic deformation. This project seeks to accurately quantify the postelastic behavior of thin films by performing nanoindentation and developing a program that can convert these results into stress-strain curves. It is done by determining and validating a mathematical model with standards and then converting load-displacement data from nanoindentation into stress-strain curves.
#53 – DNA SEPARATION USING CUSTOM-BUILT MICROFLUIDIC DEVICE MICROFLUIDIC DESIGN AND DEVELOPMENT USING METHODS OF PHOTOLITHOGRAPHY DEPARTMENT: Micron School of Material Science and Engineering TEAM MEMBERS: Hannah Byers Molly Graham Audrey Parker CLIENT: Micron School of Material Science and Engineering, Boise State Biology PROJECT ADVISORS: Dr. Harold Ackler Dr. Eric Hayden
Microfluidic devices capitalize on obtaining microscale chemical and physical properties of liquids and gasses. Composed of an array of channels and pathways, they are capable of directing, mixing, separating, and manipulating liquids for detailed analysis. Sponsored by Dr. Eric Hayden, assistant professor in the Boise State University Biology department, this project works to exploit microfluidic devices through the characterization and construction of microfluidic channels through methods of photolithography. The team has illustrated the methods for creating functioning microfluidic devices on campus which are capable of delivering known amounts of liquid to streamline DNA, RNA, and biological research.
