    • Adaptive all the way down: Building responsive materials from hierarchies of chemomechanical feedback 

      Grinthal, Alison Elizabeth; Aizenberg, Joanna (Royal Society of Chemistry (RSC), 2013)
      A living organism is a bundle of dynamic, integrated adaptive processes: not only does it continuously respond to constant changes in temperature, sunlight, nutrients, and other features of its environment, but it does so ...
    • Adaptive fluid-infused porous films with tunable transparency and wettability 

      Yao, Xi; Hu, Yuhang; Grinthal, Alison Elizabeth; Wong, Tak-Sing; Mahadevan, Lakshminarayanan; Aizenberg, Joanna (Nature Publishing Group, 2013)
      Materials that adapt dynamically to environmental changes are currently limited to two-state switching of single properties, and only a small number of strategies that may lead to materials with continuously adjustable ...
    • Bilayer Mechanical Properties Regulate Transmembrane Helix Mobility and Enzymatic State of CD39 

      Grinthal, Alison Elizabeth; Guidotti, Guido (American Chemical Society, 2005)
      CD39 can exist in at least two distinct functional states depending on the presence and intact membrane integration of its two transmembrane helices. In native membranes, the transmembrane helices undergo dynamic rotational ...
    • Bioinspired self-repairing slippery surfaces with pressure-stable omniphobicity 

      Wong, Tak-Sing; Kang, Sung; Tang, Sindy K. Y.; Smythe, Elizabeth J.; Hatton, Benjamin D.; Grinthal, Alison Elizabeth; Aizenberg, Joanna (Nature Publishing Group, 2011)
      Creating a robust synthetic surface that repels various liquids would have broad technological implications for areas ranging from biomedical devices and fuel transport to architecture but has proved extremely challenging. ...
    • Condensation on slippery asymmetric bumps 

      Park, Kyoo-Chul; Kim, Philseok; Grinthal, Alison Elizabeth; He, Neil; Fox, David; Weaver, James C.; Aizenberg, Joanna (Springer Nature, 2016)
      Controlling dropwise condensation is fundamental to water- harvesting systems1–3, desalination4, thermal power generation4–8, air conditioning9, distillation towers10, and numerous other applications4,5,11. For any of ...
    • A Constructive Chemical Conversation 

      Aizenberg, Joanna; Grinthal, Alison Elizabeth; Noorduin, Wim (Sigma Xi, 2016)
    • Dynamic polymer systems with self-regulated secretion for the control of surface properties and material healing 

      Cui, Jiaxi; Daniel, Dan; Grinthal, Alison Elizabeth; Lin, Kaixiang; Aizenberg, Joanna (Nature Publishing Group, 2015)
      Approaches for regulated fluid secretion, which typically rely on fluid encapsulation and release from a shelled compartment, do not usually allow a fine continuous modulation of secretion, and can be difficult to adapt ...
    • Liquid-based gating mechanism with tunable multiphase selectivity and antifouling behaviour 

      Hou, Xu; Hu, Yuhang; Grinthal, Alison Elizabeth; Khan, Mughees; Aizenberg, Joanna (Nature Publishing Group, 2015)
      Living organisms make extensive use of micro- and nanometre-sized pores as gatekeepers for controlling the movement of fluids, vapours and solids between complex environments. The ability of such pores to coordinate ...
    • Meniscus Lithography: Evaporation-Induced Self-Organization of Pillar Arrays into Moiré Patterns 

      Kang, Sung H.; Wu, Ning; Grinthal, Alison Elizabeth; Aizenberg, Joanna (American Physical Society (APS), 2011)
      We demonstrate a self-organizing system that generates patterns by dynamic feedback: two periodic surfaces collectively structure an intervening liquid sandwiched between them, which then reconfigures the original surface ...
    • Mobile Interfaces: Liquids as a Perfect Structural Material for Multifunctional, Antifouling Surfaces 

      Grinthal, Alison Elizabeth; Aizenberg, Joanna (American Chemical Society (ACS), 2014)
      Life creates some of its most robust, extreme surface materials not from solids but from liquids: a purely liquid interface, stabilized by underlying nanotexture, makes carnivorous plant leaves ultra-slippery, the eye ...
    • Rationally Designed Complex, Hierarchical Microarchitectures 

      Noorduin, W. L.; Grinthal, Alison Elizabeth; Mahadevan, Lakshminarayanan; Aizenberg, Joanna (American Association for the Advancement of Science (AAAS), 2013)
      The emergence of complex nano/microstructures is of fundamental interest, and the ability to program their form has practical ramifications in fields such as optics, catalysis and electronics. We developed carbonate/silica ...
    • Steering nanofibers: An integrative approach to bio-inspired fiber fabrication and assembly 

      Grinthal, Alison Elizabeth; Kang, S.H.; Epstein, A.K; Aizenberg, M.; Khan, M.; Aizenberg, Joanna (Elsevier BV, 2012)
      As seen throughout the natural world, nanoscale fibers exhibit a unique combination of mechanical and surface properties that enable them to wind and bend around each other into an immense diversity of complex forms. In ...
