Topological and morphological signatures of disorder in a self-assembled, soft matter sponge network
Xueyang Feng, Suman S. Kulkarni, Michael S. Dimitriyev +4
Many soft matter systems exhibit ordered, polycontinuous network morphologies, such as the cubic (double) gyroid or diamond, as well as disordered network morphologies known generi…
An Orbifold Framework for Classifying Layer Groups with an Application to Knitted Fabrics
Sonia Mahmoudi, Elizabeth J. Dresselhaus, Michael S. Dimitriyev
Entangled structures such as textiles and architected materials are often doubly periodic. Due to this property and their finite transverse thickness, the symmetries of these mater…
Structural Relaxation and Anisotropic Elasticity of Ordered Block Copolymer Melts
Krista G. Schoonover, Gaurav Rawat, Emily B. Pentzer +1
Block copolymer (BCP) melts play a critical role in the design of thermoplastics, owing in large part to the creation of alternating nano-scale domains of soft and stiff components…
Not even metastable: Cubic double-diamond in diblock copolymer melts
Micheal S. Dimitriyev, Benjamin R. Greenvall, Rejoy Matthew +1
We study the thermodynamics of continuous transformations between two canonical, cubic network phases of block copolymer melts: double-gyroid, an equilibrium morphology for many sy…
Chirality Effects in Molecular Chainmail
Alexander R. Klotz, Caleb J. Anderson, Michael S. Dimitriyev
Motivated by the observation of positive Gaussian curvature in kinetoplast DNA networks, we consider the effect of linking chirality in square lattice molecular chainmail networks…
Mesoscale Polymer Arrays: High Aspect Ratio Surface Structures and Their Digital Reconstruction
Demi E. Moed, Michael S. Dimitriyev, Benjamin R. Greenvall +2
Inspired by adhesive bio-filamentous structure, such as bacterial pili, this work details the methods used to fabricate and characterize a surface-anchored array of thin, flexible…
