1. A New Method of NanomanipulationXiaoqin Li, University of Texas at Austin, DMR 0747822 (a) • Atomic Force Microscope (AFM) has been used to manipulate nano-size objects. • Using the conventional method (Fig (a)), AFM is used as either a manipulation tool or an imaging tool, not both simultaneously. Iterative imaging and manipulation steps are required. • The new manipulation method consists of two steps: (ACS nano, 3, 2989; Fig (b)) • The chosen particle is pushed in a random direction and distance to reduce friction • Particle is dribbled to a target position at a high scanning speed in tapping mode; A ghost trace serves as a visual guidance during manipulation (b)

2. Broader ImpactsXiaoqin Li, University of Texas at Austin, DMR 0747822 The PI serves as a co-PI of the NSF-IGERT program. In this role, she ran the Ethic workshop each year in 2008-2010. She gave the plenary talk at APS and AAPT Texas section meeting, Austin, Texas, March 20th, 2010. Shealsodelivered a lecture at the Nano Science Summer Academy for high school students and teachers The PI delivered a public lecture at the 28th and 29th Honors Colloquium at UT-Austin attended by invited high school students in Texas in 2009 and 2010. PI’s laboratory provided research opportunities for 6 graduate students, 3 postdoctoral researchers, and 5 undergraduate students in the past funding period. “Alice in Wonderland” is a summer internship program designed to provide research opportunities for high school female students. The PI’s lab has hosted students in this program each year in the last three years including Kathy Spradlin and Lauren Niu (2nd and1st from the right) this year.
