DNA on a Tube: Electrostatic Contribution to Stiffness [PDF]
The Journal of Physical Chemistry B, 2008 Two simple models are used to estimate the electrostatic contributions to the stiffness of short DNA fragments. The first model views DNA as two strands that are appropriately parametrized and are wrapped helically around a straight cylinder radius equal to the radius of the DNA molecule.

Electrostatic Control of Thickness and Stiffness in a Designed Protein Fiber
Journal of the American Chemical Society, 2008 Attempts to design peptide-based fibers from first principles test our understanding of protein folding and assembly, and potentially provide routes to new biomaterials. Several groups have presented such designs based on alpha-helical and beta-strand building blocks.

Mechanical Simplification of Variable-Stiffness Actuators Using Dielectric Elastomer Transducers
Actuators, 2019 Legged and gait-assistance robots can walk more efficiently if their actuators are compliant. The adjustable compliance of variable-stiffness actuators (VSAs) can enhance this benefit. However, this functionality requires additional mechanical components

Electrostatic Contributions to Chain Stiffness and Excluded-Volume Effects in Sodium Poly(styrenesulfonate) Solutions [PDF]
Polymer Journal, 2000 Intrinsic viscosities for sodium poly(styrenesulfonate) in aqueous sodium chloride at 25°C have been determined for 15 samples ranging in weight-average molecular weight from 3.8×103 to 6.5×105 at five salt concentrations Cs between 0.05 and 2M. Their molecular weight dependence at each Cs is fairly satisfactorily explained by the theory of Yoshizaki ...

Design of a Capacitive MEMS Accelerometer with Softened Beams
Micromachines, 2022 Lower stiffness can improve the performance of capacitive-based microelectromechanical systems sensors. In this paper, softened beams, achieved by the electrostatic assembly approach, are proposed to lower the stiffness of a capacitive MEMS accelerometer.
