After acquiring the Infrared Imaging Microscope with large area mapping capabilities for structure-function research and education in composite and semiconducting materials, we have been largely successful in obtaining high quality, high-resolution FTIR maps of multiple biological composites. This includes the chemical mapping of the radular teeth of Cryptochiton stelleri chiton, the crush resistant exoskeleton from Phloeodes diabolicus the Iron Clad beetle, and the hard and impact resistant dactyl club from the stomatopod Odontodactylus scyllarus. The FTIR microscope has enabled us to make significant contributions in uncovering details about ultrastructural features of the various regions within these biological composites and has enabled us to begin deriving new design strategies for the synthesis of impact and abrasion-resistant composites. Through the acquisition of this FTIR microscope, we have also enabled the training and education of post-doctoral researchers, graduate and undergraduate students. Personnel that have utilized this instrument include Dr. Sourangsu Sarkar post doctoral researcher, Dr. Lessa Grunenfelder post-doctoral researcher, Parawee Pumwongpitak Ph.D. student, Nicholas Yaraghi Ph.D. student, Steven Herrera Ph.D. student, Hispanic minority, Jesus Rivera Ph.D. student, Hispanic minority, Thomas Dugger Ph.D. student, Ramya Mohan Ph.D. student, Kanako Sato visiting Ph.D. student, Brian Macdonald undergraduate student and Jeff Geiger undergraduate student. In addition to training and education, this equipment has enabled our lab to collaborate with multiple PIs around the world, including Dr. Joanna McKittrick UCSD, Dr. Matthew Shawkey Univ. Akron, Dr. Pablo Zavattieri Purdue University, Dr. Dimitri Deheyn Scripps, UCSD, Dr. Atsushi Arakaki Tokyo University of Agriculture and Technology, Dr. Yoshiaki Maeda Tokyo University of Agriculture and Technology, Dr. Hiroaki Imai Keio University.
