Braulio Dumba continued his research in the development of atomic force microscope (AFM) tip reconstruction algorithms at Luther College. In collaboration with graduate students at the University of Wisconsin and the University of Pennsylvania, Braulio implemented a quantitative comparison of our MatLab-based tip reconstructions to commercially-generated reconstructions, progressing toward our goal of an open=source, user-friendly tip reconstruction program for use by the AFM community.
Opeoluwa Matthews worked in Luther's nanotribology lab, investigating frictional properties of organic monolayer-coated aluminum oxide surfaces. He performed measurements of friction and adhesion using an atomic force microscope (AFM), quantifying the load and time evolution of these properties.
Sarice Barkley,a St. Olaf student, continued probe development and level calibration for Luther's nanotribology lab. She constructed, using a micromanipulator, more than 150 atomic force microscope colloidal probes, experimentally determining the key force constants for each lever in the process.

Braulio Dumba traveled to the National Physical Laboratory (NPL) just outside of London, England for eight weeks to continue his research in atomic force microscope (AFM) tip reconstruction algorithms. During his collaboration work with research scientists and students at NPL, Braulio learned to run commercial tip reconstruction software programs for a comparison of those programs to our own tip reconstruction algorithms.
Jared Wilkins continued his research in implementing AFM calibration techniques in Luther’s nanotribology lab, developing a new organizational scheme for quickly and efficiently calculating spring constants for AFM cantilevers. Jared also implemented a new friction vs. load technique on the AFM using open-architecture software.
Brian Nowosatka improved techniques for attaching microspheres to AFM cantilevers during his summer in Luther’s nanotribology lab. Brian also investigated the effects of scan rate, scan speed, and scan size on the height and friction variation produced as these so-called colloidal probes are scanned in the AFM.
