Nonlocal, nonlinear electrostatics: like-charge attraction and asymmetric solvation
V. Stepanyan, Y. Sh. Mamasakhlisov, A. E. Allahverdyan
We study an equilibrium system, where linear molecules with a rigid charge distribution interact via the mean-field generated by the Coulomb coupling. We focus on the nonlinear reg…
Nonlocal Electrostatic Field Theory from Microscopic Description
Varazdat Stepanyan, Yevgeni Sh. Mamasakhlisov, Armen E. Allahverdyan
The study of electric fields in soft materials converges either to the study of point-like particles (local) in nonlinear theories or to the use of particles with finite sizes in n…
Glassy state of native collagen fibril
S. G. Gevorkian, A. E. Allahverdyan, D. S. Gevorgyan +1
Our micromechanical experiments show that at physiological temperatures type I collagen fibril has several basic features of the glassy state. The transition out of this state [sof…
Kinetics of the helix-coil transition
Armen E. Allahverdyan, Sasun G. Gevorkian, Aleksandr Simonian
Based on the Zimm-Bragg model we study cooperative helix-coil transition driven by a finite-speed change of temperature. There is an asymmetry between the coil-to-helix and helix-t…
How adsorption influences DNA denaturation
A. E. Allahverdyan, Zh. S. Gevorkian, Chin-Kun Hu +1
The thermally induced denaturation of DNA in the presence of attractive solid surface is studied. The two strands of DNA are modeled via two coupled flexible chains without volume…
Thermal (in)stability of type I collagen fibrils
S. G. Gevorkian, A. E. Allahverdyan, D. S. Gevorgyan +1
We measured Young's modulus at temperatures ranging from 20 to 100 ^{\circ}$C for a collagen fibril taken from rat's tendon. The hydration change under heating and the damping decr…
