Competing addition processes give distinct growth regimes in the assembly of 1D filaments
Sk Ashif Akram, Tyler Brown, Stephen Whitelam +3
We present a model to describe the concentration-dependent growth of protein filaments. Our model contains two states, a low entropy/high affinity ordered state and a high entropy/…
Effects of non-pairwise repulsion on nanoparticle assembly
Sawyer S. Hopkins, Amitabha Chakrabarti, Jeremy D. Schmit
Electrostatic interactions provide a convenient way to modulate interactions between nanoparticles, colloids, and biomolecules because they can be adjusted by the solution pH or sa…
Intermolecular adhesion in conjugated polymers: The role of the band gap and solitonic excitations
Jeremy D. Schmit, Alex J. Levine
Conjugated polymers are soft, one-dimensional conductors that admit complex interactions between their polymeric, conformational degrees of freedom and their electronic ones. The p…
What drives amyloid molecules to assemble into oligomers and fibrils?
Jeremy Schmit, Kingshuk Ghosh, Ken Dill
We develop a general theory for three states of equilibrium of amyloid peptides: the monomer, oligomer, and fibril. We assume that the oligomeric state is a disordered micelle-like…
Electrostatics and aggregation: how charge can turn a crystal into a gel
Jeremy Schmit, Stephen Whitelam, Ken Dill
The crystallization of proteins or colloids is often hindered by the appearance of aggregates of low fractal dimension called gels. Here we study the effect of electrostatics upon…
Diffusion limited reactions in confined environments
Jeremy D. Schmit, Ercan Kamber, Jané Kondev
We study the effect of confinement on diffusion limited bimolecular reactions within a lattice model where a small number of reactants diffuse amongst a much larger number of inert…
Intermolecular Adhesion in Conjugated Polymers
Jeremy D. Schmit, Alex J. Levine
Conjugated polymers are observed to aggregate in solution. To account for this observation we propose a inter-chain binding mechanism based on the intermolecular tunneling of the d…
Intermolecular adhesion in conducting polymers
Jeremy D. Schmit, Alex J. Levine
We analyze the interaction of two conducting, charged polymer chains in solution using a minimal model for their electronic degrees of freedom. We show that a crossing of the two c…
