Thermodynamic definition of mean temperature
A. E. Allahverdyan, S. G. Gevorkian, Yu. A. Dyakov +1
The notion of mean temperature is crucial for a number of fields including climate science, fluid dynamics and biophysics. However, so far its correct thermodynamic foundation is l…
Application of light pressure in the rheology of biopolymers
Sasun G. Gevorkian, Artashes V. Karmenyan, Chin-Kun Hu
Precise measuring the deforming force and observation of the deformation dynamics along with difficulties of micro sample preparation are the main problems which make the micro-sca…
Thermal-induced proteinquake in oxyhemoglobin
S. G. Gevorkian, A. E. Allahverdyan, D. S. Gevorgyan +1
Oxygen is released to living tissues via conformational changes of hemoglobin from R-state (oxyhemoglobin) to T-state (desoxyhemoglobin). The detailed mechanism of this process is…
Carnot Cycle at Finite Power: Attainability of Maximal Efficiency
Armen E. Allahverdyan, Karen V. Hovhannisyan, Alexey V. Melkikh +1
We want to understand whether and to which extent the maximal (Carnot) efficiency for heat engines can be reached at a finite power. To this end we generalize the Carnot cycle so t…
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…
