Talk Title: Hybrid Organic-Inorganic Films Fabricated Using Atomic and Molecular Layer Deposition
Series: Lyman L. Handy Colloquia
Abstract: Atomic layer deposition (ALD) and molecular layer deposition (MLD) are based on sequential, self-limiting surface reactions that produce atomic layer controlled and conformal thin film growth. ALD can deposit inorganic films and MLD can deposit organic films containing inorganics. ALD and MLD can also be used together to fabricate a wide range of alloy films with variable inorganic and organic composition. This talk will focus on the growth and properties of metal alkoxide films known as “metalcones” that are grown using metal precursors and various organic alcohols. The talk will highlight the tunable mechanical properties of alucone alloys grown using Al2O3 ALD and alucone MLD and the tunable electrical conductivity of zincone alloys grown using ZnO ALD and zincone MLD. In addition, the talk will discuss the pyrolysis of hybrid organic-inorganic films to produce conducting metal oxide/carbon composite films.

Talk Title: Engineering hydrogels as synthetic extracellular matrices for cell culture and tissue regeneration
Series: Cornelius Pings Lecture
Abstract: Methods for culturing mammalian cells in a biologically relevant context are increasingly needed to study cell and tissue physiology, expand and differentiate progenitor cells, and to grow replacement tissues for regenerative medicine. Two dimensional culture has been the paradigm for in vitro cell culture; however, evidence and intuition suggest that cells behave differently when they are isolated from the complex architecture of their native tissues and constrained to petri dishes or material surfaces with unnaturally high stiffness, polarity, and surface to volume ratio. As a result, biologists are often faced with the need for a more physiologically relevant 3D culture environment, and many researchers are realizing the advantages of hydrogels as a means of creating custom 3D microenvironments with highly controlled chemical, biological and physical cues. Further, the native extracellular matrix (ECM) is far from static, so ECM mimics must also be dynamic to direct complex cellular behavior. In general, there is an un-met need for materials that allow user-defined control over the spatio-temporal presentation of important signals, such as integrin-binding ligands, growth factor release, and biomechanical signals. Developing such hydrogel mimics of the ECM for 3D cell culture is an archetypal engineering problem, requiring control of numerous properties on multiple time and length scales important for cellular functions. New materials systems have the potential to significantly improve our understanding of how cells receive information from their microenvironment and the role that these dynamic processes may play in controlling the stem cell niche to cancer metastasis. This talk will illustrate our recent efforts to advance hydrogel chemistries for 3D cell culture and dynamically control biochemical and biophysical properties through orthogonal, photochemical reaction mechanisms.
Biography: KRISTI S. ANSETH is a Howard Hughes Medical Institute Investigator and Distinguished Professor of Chemical and Biological Engineering at the University of Colorado at Boulder. Dr. Anseth came to CU after earning her B.S. degree from Purdue University in 1992 and her Ph.D. degree from the University of Colorado in 1994 and completing post-doctoral research at MIT as an NIH fellow. Her research interests lie at the interface between biology and engineering where she designs new biomaterials for applications in drug delivery and regenerative medicine. Dr. Anseth’s research group has published over 250 publications in peer-reviewed journals and presented over 200 invited lectures in the fields of biomaterials and tissue engineering. She was the first engineer to be named a Howard Hughes Medical Institute Investigator and received the Alan T. Waterman Award, the highest award of the National Science Foundation for demonstrated exceptional individual achievement in scientific or engineering research. Dr. Anseth is an elected member of the National Academy of Engineering (2009), the Institute of Medicine (2009), and the National Academy of Sciences (2013). She is also a dedicated teacher, who has received four University Awards related to her teaching, as well as the American Society for Engineering Education’s Curtis W. McGraw Award. Dr. Anseth is a Fellow of the American Association for the Advancement of Science, the American Institute for Medical and Biological Engineering, and the Materials Research Society. She serves on the editorial boards or as associate editor of Biomacromolecules, Journal of Biomedical Materials Research â Part A, Acta Biomaterialia, Progress in Materials Science, and Biotechnology & Bioengineering.

MFD - Chemical Engineering and Materials Science Graduate Seminar
Wed, Feb 26, 2014 @ 12:45 PM - 01:50 PM

Speaker: Professor Masoud Soroush, Drexel University
Talk Title: Long-Term Academia-Industry Collaboration: The Drexel-DuPont Experience
Series: Graduate Seminar Series
Abstract: Long-term academia-industry research collaboration is rewarding but challenging.
Drexel and DuPont collaborated at different levels for more than a decade. What
began as a personal collaboration in multirate state estimation later evolved into a broad university-corporation collaboration in process systems engineering and
polymer engineering lasting more than a decade.
In this talk, the evolution of this collaboration, in terms of the type of projects
involved and the level of corporation participation, is described. The challenges
and rewards of such a collaboration are described based on this collaboration
experience. Results of collaborative projects involving multirate state estimation,
instrument fault detection and identification, polymer reaction engineering, and
quantum-chemical study of acrylate self-initiation reactions are presented.

He was a Visiting Scientist at DuPont Marshall Lab 2002-03 and a Visiting Professor in the Department of Chemical and Biological Engineering at Princeton University in 2008. His awards include the Faculty Early CAREER Award from the National Science Foundation in 1997, the O. Hugo Schuck Best Paper Award from the American Automatic Control Council in 1999, and the Faculty Achievement Award for Excellence in Teaching from Drexel University in 1999. His research interests are in process systems engineering; mathematical modeling, analysis, and computational design and optimization of fuel cells, solar cells, and power storage systems; probabilistic modeling, risk assessment, and prediction of rare events; fault detection and identification; polymer engineering; and quantum chemical calculations.
