John R. Hellmann is Professor of Materials Science and Engineering and Associate Dean for Education in the College of Earth and Mineral Sciences. As a Penn State faculty member since 1986, he has also served as Associate Director of the Center for Advanced Materials (1986-1995), Chairman of the Ceramic Science and Engineering Program (1998-2001), and as Associate Head for Undergraduate Studies in Materials Science and Engineering (2001-2007). In addition to maintaining an active teaching and research portfolio, in his new position as Associate Dean he is responsible for curriculum, accreditation, recruiting and retention, scholarships, international internships, and outreach activities in the College of Earth and Mineral Sciences
His research interests concern the mechanical reliability and thermochemical durability of ceramics, metals, and intermetallic materials in severe thermal environments. He has active research programs in development and characterization of materials for gas turbines, advanced propulsion systems, and enhanced oil and natural gas recovery technology, as well as in the design and fabrication of laminated ceramic composites possessing engineered stress states for use as armor and cutting tools. He has published over one hundred peer reviewed papers on research supported by the Department of Energy, NASA, Office of Naval Research, National Science Foundation, and industry, and has supervised the research of over 120 graduate and undergraduate students, many of whom have received national and international awards for their work.
Professor Hellmann earned his bachelor and doctorate degrees in Ceramic Science at Penn State, followed by a five year stint as a member of technical staff at Sandia National Laboratories in Albuquerque, New Mexico prior to returning to the faculty at Penn State.
A Fellow of the American Ceramic Society, Professor Hellmann has also served on the Society’s Board of Directors, as President of the Ceramic Educational Council, President of the National Institute of Ceramic Engineers, Associate Editor of the Journal of the American Ceramic Society, and was recently named a Distinguished Mentor by the Society for his role in advising and nurturing students and young professionals in the field of materials science and engineering.

Mike Hickner received a B.S. in Chemical Engineering from Michigan Technological University (Michigan Tech) and a M.S. and Ph.D. in Chemical Engineering from Virginia Polytechnic Institute and State University (Virginia Tech). In graduate school he worked under the direction of James E. McGrath and also spent time at Los Alamos National Laboratory. Before joining Penn State as an Assistant Professor in 2007, he was a postdoc and subsequently became a staff member at Sandia National Laboratories. Professor Hickner’s research and teaching interests include all aspects of polymeric materials, polymer micro- and nano-structure, transport characterization, spectroscopy, electrochemistry, and new materials for energy applications.
Research in the Hickner group probes the connection between the molecular identity, nanophase structure, and the resulting transport properties in polymeric materials. Our activities are motivated by application-specific needs that drive fundamental investigations into new materials chemistry and demand incisive measurements of the structure and transport properties of novel materials. We characterize technologically important materials and synthesize model materials systems to probe specific structural and property questions.
A significant thrust in our group is directed towards the study of ion-containing polymers that form robust membranes and absorb water. These types of materials are the basic functional units of solid-state electrochemical systems such as fuel cells and electrolyzers and enable water treatment technologies such as nanofiltration and reverse osmosis. The binding and diffusion of the absorbed water internal to the membrane structure and the interactions between the polymer, ions, and water are important aspects of these materials which ties the transport properties to the nano-scale and molecular features.
We employ tools such as impedance spectroscopy, NMR, TEM, AFM, vibrational spectroscopy, calorimetry, and scattering to probe the structure and transport in multiphase polymeric materials. Our team is composed of a diverse group of materials scientists, chemists, and engineers with wide ranging skills in synthesis, advanced experimental technique development, and analytical analysis. Ultimately, the goal of our group’s work is to have impact on novel applications of polymer membranes and to uncover the fundamental factors that influence the structure and resulting properties of polymeric materials.

Professor Manias received his B.S. degree in Physics from the Aristotle U in Thessaloniki, Greece, and his Ph.D. in Chemistry from U. of Groningen, the Netherlands. He subsequently carried out postdoctoral research in the Materials Science and Engineering department at Cornell U, before joining Penn State as an assistant professor in 1998. His research combines theoretical, simulation, and experimental approaches focused on explaining how nanoscale structures affect the macroscopic materials properties in multi-phase polymer systems, and on further designing appropriate structures and functionalities that lead to high-performance novel materials.
Professor Manias’ research focuses on the development of new high performance polymer and polymer-composite materials, with approaches spanning the range from basic-science fundamentals to engineering development of materials designed for specific applications. All of these research efforts exploit the unique opportunities of nanoscale structures and nanoscopic components in polymer and organic materials.
More specifically, examples of recent work in Professor Manias’ research group include: (a) development of high performance polymer/inorganic nanocomposites, involving synthesis, processing, fundamental physics, and engineering design approaches; (b) atomic force microscopy (AFM) studies of polymer surfaces and polymer nanostructures, including he development of new state-of-the-art instruments and modifications of AFM modes of operation; (c) fundamental understanding of nanoscopically confined polymer electrolytes and lubricants, based on molecular modeling; and (d) design and syntheses of smart polymers that respond to external stimuli –such as temperature, electric fields, and pH– and applications of these smart materials in biomedical and surface applications.
A unique feature of Manias’ research group approach in its investigations is the concurrent in-depth employment of polymer physics, molecular modeling computer simulations, synthetic chemistry, and engineering approaches –design, processing, characterization, structure-property relations, and application-driven materials development. The feedback and cross-fertilization between fundamental science, computer modeling, and engineering approaches offers unprecedented opportunities for fast progress in research, and to date has yielded diverse results that were featured in eminent scientific journals of physics, polymers, and engineering, new technologies that were patented, and new advances in materials that were featured in popularized-science books and magazines.
