报告内容摘要：
      In the speech, the professor will briefly overview recent results from our research group on designing bio-inspired hybrid, organic-inorganic nanomaterials and microstructures with enhanced sensing performance. Particularly, suspended membranes of snake thermal receptors served as an example for the fabrication of freely standing flexible nanomembranes by means of layer-by-layer assembly which are explored as extremely sensitive un-cooled thermal and acoustic microsensors. In addition, examples of LbL assembly of flexible gold-containing microcapsules with different shapes are discussed as intriguing delivery and storage vehicles and mesoscale building blocks.  In a second example, synthetic hydrogel capped hairs with record fluid flow detection limit were mimicked after biocupulae of blind cave fish which serve for robust underwater navigation of these species.  Finally, unique torsional properties of suspended air-sensing microscopic hairs of jumping spiders were directly measured with point-load surface force spectroscopy experiments.

报告人简介：
     Prof. Vladimir V. Tsukruk received his M.S. degree in Physics in 1978 from the National University of Ukraine, Ph.D and DSc in Chemistry in 1983 and 1988 from the National Academy of Sciences of Ukraine. He held post-doctoral positions with J. Wendorff (U. Marburg) and D. Reneker (U Akron). Currently, he holds an appointment as a Professor at the School of Materials Science and Engineering Georgia Institute of Technology.  He is a founding co-director of a new GT-Air Force Center of Excellence on BIONIC.  He has co-authored 300+ refereed articles in archival journals, 20+ invited reviews and one book, co-edited three volumes, and holds four patents.  He is ranked within top 1% highly cited researchers both in chemistry and materials with about 7000 citations. His research group of about 20 students and post-docs who conduct research in the fields of nanostructured surfaces/interfaces, molecular assembly, nano- and bioinspired materials is supported by NSF, AFOSR, DOE, DARPA, and private industry. 
      He is a Fellow, American Physical Society (2010) and is recipient of the Humboldt Research Award (2009), NSF Special Creativity Award (2006), NSF RIA Young Investigator Award (1994), Humboldt Fellowship (1990), Best Young Investigator Research Prize in Ukraine (1985), among others.  He serves on the editorial advisory boards of Langmuir, ACS Appl. Mater.&Interfaces, Polymer, Res. Lett. Mater. Sci., and Curr. Chem. Biology.  He has organized eight international symposia and workshops, served as a Program Chair for Polymer Materials Division, ACS, and graduated about 40 graduate students and post-docs who continue successful carriers in academia, industry, and national labs.
