dc.description	Dr. Kenneth H. Sandhage presented a lecture at the Nano@Tech Meeting on February 26, 2013 at 12 noon in room 1116 of the Marcus Nanotechnology Building.	en_US
dc.description	Dr. Ken H. Sandhage is the B. Mifflin Hood Professor in the School of Materials Science and Engineering, and an Adjunct Professor in the School of Chemistry and Biochemistry at the Georgia Institute of Technology. He is the Director of the Center for Biologically Enabled Advanced Manufacturing (BEAM). Dr. Sandhage received a B.S. (1981) in Metallurgical Engineering with highest distinction from Purdue University, and a Ph.D. (1986) in Ceramics from the Massachusetts Institute of Technology. After working as a Senior Scientist at Corning, Inc. and American Super-conductor Corp., he was on the faculty in the Dept. of Materials Science and Engineering at Ohio State University for 12 years before joining Georgia Tech in 2003. Dr. Sandhage’s research focuses on novel reaction processing of advanced materials for electromagnetic, chemical, optical, sensor, refractory, and structural applications. This research has resulted in several patented processes for fabricating near net-shaped ceramics and composites at modest temperatures: the Bioclastic and Shape -preserving Inorganic Conversion or BaSIC method, U.S. Patent 7,067,104; the Displacive Compensation of Porosity or DCP method, U.S. Patent 6,407,022; the Volume Identical Metal Oxidation or VIMOX method, U.S. Patent 5,447,291. Sandhage and his students hold 23 patents. A major current initiative is biologically-enabled materials processing, including Genetically Engineered Materials and Micro/nanodevices (GEMs). Dr. Sandhage has received several distinctive honors throughout his career, including: 5 best paper awards, such as the Purdy Award from the American Ceramic Society (1996); the Outstanding Materials Engineer Award from Purdue (1997); and the Lumley Research Award from Ohio State (1997, 2002). In 1999-2000, he was a Humboldt Fellow in the Advanced Ceramics Group at the Technical University of Hamburg-Harburg. He was the advisor to students Matt Dickerson and Ray Unocic, who were recipients of the 2002 National Collegiate Inventors Award. Dr. Sandhage is a Fellow of the American Ceramic Society, a member of the National Materials Advisory Board of the National Academies, and a member of the Materials Research Society and TMS. He has also been a technical consultant for a number of companies and law firms.

dc.description.abstract	Nature provides remarkable examples of microscale structures with complex three-dimensional (3-D) morphologies and finely-patterned features formed by living organisms. For example, intricate 3-D microscale silica or chitinous structures with organized nanoscale features are formed by diatoms (single celled algae) or Morpho butterflies, respectively. Synthetic rapid-prototyping or self-assembly approaches have also yielded 3-D structures with microscale and/or nanoscale particles/pores in certain desired arrangements. While such 3-D patterned structures can be attractive for particular applications, the materials readily formed by these processes may not possess preferred chemistries for a broader range of uses. The scalable fabrication of structures with complex 3-D morphologies and with a range of tailorable chemistries may be accomplished by separating the processes for structure formation and for chemical tailoring; that is, structures with a desired 3-D morphology may first be assembled in a readily-formed chemistry and then converted into a new functional chemistry via a morphology-preserving transformation process. In this presentation, several shape-preserving chemical conversion (conformal coating-based and fluid/solid reaction-based) approaches will be discussed for generating 3-D replicas of biogenic and synthetic structures comprised of ceramic, metal, or composite materials for catalytic, optical, energy harvesting/storage, and aerospace applications.	en_US
