Entropy, a physical property often explained as “disorder,” is revealed as a creator of order with a new bonding theory developed at the University of
Oct. 25, 2021 -- Researchers at the Cornell University Center for Advanced Computing (CAC), Texas Tech University, and Indiana University are engaged in a
Abstract Morphing structures are often engineered with stresses introduced into a flat sheet by leveraging structural anisotropy or compositional heterogeneity. Here, we identify a simple and universal diffusion-based mechanism to enable a transient morphing effect in structures with parametric surface grooves, which can be realized with a single material and fabricated using low-cost manufacturing methods (e.g., stamping, molding, and casting). We demonstrate from quantitative experiments and multiphysics simulations that parametric surface grooving can induce temporary asynchronous swelling...
