1. GOALI: Crystallization of Organic GlassesLian Yu, University of Wisconsin-Madison, DMR 0907031 Our team measured for the first time surface diffusion on organic solids. Our data indicate more than one-million-fold surface enhancement of diffusion, which can support surface crystal growth and formation of stable glasses by vapor deposition. Our data show that surface diffusion kinetics on organic glasses differs significantly from that on metals Surface diffusion from surface grating decay Mobile surface Frozen glass Indomethacin (IMC) Zhu, Ediger, Yu et al.

2. GOALI: Crystallization of Organic GlassesLian Yu, University of Wisconsin-Madison, DMR 0907031 Our group played a key part in the UW PEOPLE program designed to broaden the education of high-school students from underrepresented groups. This year’s class was on polymers. The 15 students learned about chemical bonds, polymer structures, the effect of crosslinking on physical properties, and the use of polymers in nanolithography. The results from our research were part of the course materials which Yu used in his graduate course Molecular Solids, and an X-ray diffraction workshop at NYU. Our work has had strong impact in the pharmaceutical science community. Yu has organized conferences and given lectures on amorphous drugs. AAPS recognized the success of this project in conferring to the laboratory one of its highest awards – David Grant Award in Physical Pharmacy. Dr. Danielle Musumeci explains materials chemistry to high-school students in the UW PEOPLE program Caleb Brian, a graduate student participating in this work, received the AAPS Graduate Student Symposium award in recognition of his achievement. Dissemination of research results: The students and PI presented the results in scientific meetings, universities, and companies.
