Molecular chirality controls droplet division and helical fiber formation in liquid crystal emulsions
Simon Čopar, Mariana V. M. Rodriguez, Peter Marinko +9
Molecular chirality is a source of broken mirror symmetry, but using it to control mesoscale structures with a tunable length scale remains challenging. Here, we demonstrate that a…
Polymer threadings and rigidity dictate the viscoelasticity and nonlinear relaxation dynamics of entangled ring-linear blends and their composites with rigid rod microtubules
Karthik R. Peddireddy, Ryan Clairmont, Rae M. Robertson-Anderson
Mixtures of polymers of varying topologies and stiffnesses display complex emergent rheological properties that often cannot be predicted from their single-component counterparts.…
OpTiDDM (Optical Tweezers integrating Differential Dynamic Microscopy) maps the spatiotemporal propagation of nonlinear stresses in polymer blends and composites
Karthik R. Peddireddy, Ryan Clairmont, Philip Neill +2
How local stresses propagate through polymeric fluids, and, more generally, how macromolecular dynamics give rise to viscoelasticity are open questions vital to wide-ranging scient…
Cellulose-Based Reflective Liquid Crystal Films as Optical Filters and Solar Gain Regulators
Joshua A. De La Cruz, Qingkun Liu, Bohdan Senyuk +3
Many promising approaches for designing interactions of synthetic materials with light involve solid optical monocrystals and nanofabricated photonic crystal structures with spatia…
Monge-Ampère functionals for the curvature tensor of a holomorphic vector bundle
Jean-Pierre Demailly
Let be a holomorphic vector bundle on a projective manifold such that is ample. We introduce three functionals related to Griffiths, Nakano and dual Nakano p…
DNA topology dictates strength and flocculation in DNA-microtubule composites
Karthik R. Peddireddy, Davide Michieletto, Gina Aguirre +3
Polymer composites are ubiquitous in biology and industry alike, owing to their emergent desirable mechanical properties not attainable in single-species systems. At the same time,…
Active restructuring of cytoskeleton composites leads to increased mechanical stiffness, memory, and heterogeneity
Janet Y. Sheung, Daisy H. Achiriloaie, Karthik Peddireddy +5
The composite cytoskeleton, comprising interacting networks of semiflexible actin and rigid microtubules, actively generates forces and restructures using motor proteins such as my…
Viscoelastic properties of ring-linear DNA blends exhibit non-monotonic dependence on blend composition
K. R. Peddireddy, M. Lee, C. M. Schroeder +1
Entangled ring polymers, along with blends of ring and linear polymers, continue to be a topic of great interest and debate due to the conflicting experimental results in the liter…
Unexpected entanglement dynamics in semidilute blends of supercoiled and ring DNA
Karthik R. Peddireddy, Megan Lee, Yuecheng Zhou +4
Blends of polymers of different topologies, such as ring and supercoiled, naturally occur in biology and often exhibit emergent viscoelastic properties coveted in industry. However…
Synergistic interactions between DNA and actin trigger emergent viscoelastic behavior
Robert Fitzpatrick, Davide Michieletto, Karthik R. Peddireddy +4
Composites of flexible and rigid polymers are ubiquitous in biology and industry alike, yet the physical principles determining their mechanical properties are far from understood.…
