FALL 2004 TECHSTRACKS Materials Science and Engineering

A newsletter for Keck Laboratory for Combinatorial alumni and friends of the Department of Nanosynthesis and Multiscale Materials Science and Engineering Characterization he University of Maryland has received a major award of $750,000 from the W. M. TKeck Foundation of Los Angeles to establish a new Laboratory for Combinatorial Nanosynthesis and Multiscale Characterization. Conceived by Professors Ichiro Takeuchi, Gary W. Rubloff, and Ellen Williams, the Keck Laboratory will be a centerpiece for INSIDE pioneering research which extends campus strengths in combinatorial materials science, 2 Message from scanning nanoprobes, and highly controlled materials synthesis profoundly into the the Chair nanoscale domain to enable fundamentally new insights into the behavior of materials at the nanoscale. 3 Student News
