On the Humble Origins of the Brownian Entropic Force
Richard M. Neumann
Recognition that certain forces arising from the averaging of the multiple impacts of a solute particle by the surrounding solvent particles undergoing random thermal motion can be…
The Role of Chain Entropy in an Analytic Model of Protein Binding in Single-DNA Stretching Experiments
Pui-Man Lam, Richard M. Neumann
We show that the simple analytical model proposed by Zhang and Marko (Phys. Rev. E 77, 031916 (2008)) to illustrate Maxwell relations for single-DNA experiments can be improved by…
Molecular association at the microscopic level
Richard M. Neumann
The Helmholtz free-energy W is calculated as a function of separation distance for two molecules in a fluid, A and B, whose mutual interaction is described by a spherically symmetr…
Phase Diagram for Unzipping DNA Using a Bond-Force Criterion
Richard M. Neumann
Using the criterion that the mechanical unzipping transition in a bound homopolymer is triggered when the average force exerted by the single unbound strands on the first base pair…
Entropic Elasticity of Weakly Perturbed Polymers
Richard M. Neumann
Taking into account the nonequivalence of fixed-force and fixed-length ensembles in the weak-force regime, equations of state are derived that describe the equilibrium extension or…
Ideal-Chain Collapse in Biopolymers
Richard M. Neumann
A conceptual difficulty in the Hooke's-law description of ideal Gaussian polymer-chain elasticity is sometimes apparent in analyses of experimental data or in physical models desig…
