Coarse-graining bistability with the Martini force field
Alexander D. Muratov, Vladik A. Avetisov
An increasing interest in molecular structures whose long term dynamics resemble those of bistable mechanical systems promotes the search of possible candidates that may operate as…
Spontaneous Vibrations and Stochastic Resonance of Short Oligomeric Springs
Alexey M. Astakhov, Vladislav S. Petrovskii, Maria A. Frolkina +4
There is growing interest in molecular structures that exhibit dynamics similar to bistable mechanical systems. These structures have the potential to be used as nanodevices with t…
Spontaneous synchronization of two bistable pyridine-furan nanosprings connected by an oligomeric bridge
Anastasia A. Markina, Maria A. Frolkina, Alexander D. Muratov +3
The intensive development of nanodevices acting as two-state systems has motivated the search for nanoscale molecular structures whose long-term conformational dynamics are similar…
Optimal Entanglement of Polymers Promotes Formation of Highly Oriented Fibers
Artem Petrov, Vladimir Yu. Rudyak, Alexander Chertovich
Polymer fibers consist of macromolecules oriented along the fiber axis. Better alignment of chains leads to an increased strength of the fiber. It is believed that the key factor p…
Simulation of the RAFT polymerization in 3D: steric restrictions and incompatibility between species
Alexey A. Gavrilov, Alexander V. Chertovich
In this work we developed a RAFT polymerization model taking into account the main reactions of the experimental RAFT process and implemented that model in dissipative particle dyn…
Short pyridine-furan springs exhibit bistable dynamics of Duffing oscillators
Vladik A. Avetisov, Maria A. Frolkina, Anastasia A. Markina +2
The intensive development of nanodevices acting as two-state systems has motivated the search for nanoscale molecular structures whose dynamics are similar to those of bistable mec…
Modelling of thermosensitive stereoregular polymers within MARTINI coarse-grained force-field: poly(N-isopropylacrylamide) as a benchmark case
Alexander D. Muratov, Anastasia A. Markina, Dmitry V. Pergushov +1
In this article we introduce the MARTINI model of a widely used thermoresponsive polymer, Poly(N-isopropylacrylamide). Importantly, our model takes into account polymer's stereoreg…
Detection of single molecules using stochastic resonance of bistable oligomers
Anastasia Markina, Alexander Muratov, Vladislav Petrovskii +1
Our computer simulations have shown that the large-scale conformational dynamics of a short oligomeric fragment of thermoresponsive polymers resemble the mechanical movement of non…
Spatial structure and aggregation of carbon allotrope nanofillers in isotactic polypropylene composites studied by small-angle neutron scattering
L. V. Elnikova, A. N. Ozerin, V. G. Shevchenko +4
We study the aggregation of carbon allotrope nanofillers in the matrix of isotactic polypropylene with direct small-angle neutron scattering measurements. With the ATSAS software,…
Fractional Brownian motion meets topology: statistical and topological properties of globular macromolecules with volume interactions
A. M. Astakhov, V. A. Avetisov, S. K. Nechaev +1
In the paper we investigate statistical and topological properties of fractional Brownian polymer chains, equipped with the short-range volume interactions. The attention is paid t…
Core-shell microgels via precipitation polymerization: computer simulations
Alexey A. Gavrilov, Vladimir Yu. Rudyak, Alexander V. Chertovich
In this work we presented a novel computational model of precipitation polymerization allowing one to obtain core-shell microgels via a realistic cross-linking process based on the…
Statistical Properties of a Polymer Globule Formed during Collapse with the Irreversible Coalescence of Units
A. M. Astakhov, S. K. Nechaev, K. E. Polovnikov
Collapse of the polymer chain upon the sharp decrease of solvent quality is studied. During collapse, any pair of polymer units appearing in a sufficiently close vicinity in space…
Phase Behavior of Melts of Diblock-Copolymers with One Charged Block
Alexey A. Gavrilov, Alexander V. Chertovich, Igor I. Potemkin
In this work we investigated the phase behavior of melts of block-copolymers with one charged block by means of dissipative particle dynamics with explicit electrostatic interactio…
Modelling Polymerization-Induced Self Assembly (PISA)
Ruslan Shupanov, Pavel Kos, Alexei Gavrilov +1
In this work we studied polymerization-induced self-assembly by means of computer simulations. Using this model, phase diagrams of the micelle states were constructed depending on…
Diffusion to capture and the concept of diffusive interactions
Marta Galanti, Duccio Fanelli, Sergey D. Traytak +1
Diffusion to capture is an ubiquitous phenomenon in many fields in biology and physical chemistry, with implications as diverse as ligand-receptor binding on eukaryotic and bacteri…
Topological metastability of textures in biaxial nematics
V. L. Golo, E. I. Kats, D. O. Sinitsyn
We consider textures of biaxial nematics confined between two parallel plates. The boundary conformations at the bordering plates are supposed to be identical, the gradients of the…
Twisted quasiperiodic textures of biaxial nematics
V. L. Golo, E. I. Kats, A. A. Sevenyuk +1
Textures (i.e., smooth space non-uniform distributions of the order parameter) in biaxial nematics turned out to be much more difficult and interesting than expected. Scanning the…
External force affected escape of Brownian particles from a potential well
A. I. Shushin
The effect of an external force on the kinetics of diffusion-assisted escaping of Brownian particles from a potential well is analyzed in detail. The analysis is made within the tw…
