Mesoscopic magnetomechanical hysteresis in a magnetorheological elastomer.

Physical review. E, Statistical, nonlinear, and soft matter physics

Biller AM, Stolbov OV, Raikher YL.
PMID: 26382539
Phys Rev E Stat Nonlin Soft Matter Phys. 2015 Aug;92(2):023202. doi: 10.1103/PhysRevE.92.023202. Epub 2015 Aug 26.

Field-induced magnetostatic interaction in a pair of identical particles made of a magnetically soft ferromagnet is studied. It is shown that due to saturation of the ferromagnet magnetization, this case differs significantly from the (super)paramagnetic one. A numerical solution...

Factors Controlling the Reactivity of Catalytically Active Monolayers on Metal Substrates.

The focus of this work is on the Pt/MS structures (MS = Au, Ir, Ru, or Pt substrate), as promising electrocatalysts and a prototype for more general systems: (active element monolayer)/(metal substrate) (AE/MS). We evaluate from first principles the...

Unidirectional adsorbate motion on a high-symmetry surface: "walking" molecules can stay the course.

Physical review letters

Kwon KY, Wong KL, Pawin G, Bartels L, Stolbov S, Rahman TS.
PMID: 16241817
Phys Rev Lett. 2005 Oct 14;95(16):166101. doi: 10.1103/PhysRevLett.95.166101. Epub 2005 Oct 11.

Step edges and low-symmetry faces of metal crystals can restrict the diffusive motion of adsorbates, yet they offer little flexibility with regards to the location and/or direction of the guided motion. We show inherently unidirectional motion of an organic...

First-principles study of some factors controlling the rate of ammonia decomposition on Ni and Pd surfaces.

The Journal of chemical physics

Stolbov S, Rahman TS.
PMID: 16351302

Using the plane-wave pseudopotential method within the density-functional theory with the generalized gradient approximation for exchange and correlation potential, we have calculated adsorption energies (E(ad)), diffusion barrier, and the first dissociation barrier (E(1)) for NH(3) on Ni and Pd...

Numerical modeling of large field-induced strains in ferroelastic bodies: a continuum approach.

Journal of physics. Condensed matter : an Institute of Physics journal

Raikher YL, Stolbov OV.

A consistent continuum model of a soft magnetic elastomer (SME) is presented and developed for the case of finite strain. The numeric algorithm enabling one to find the field-induced shape changes of an SME body is described. The reliability...

Temporal organization of magnetospheric fluctuations unveiled by recurrence patterns in the Dst index.

Magnetic storms constitute the most remarkable large-scale phenomena of nonlinear magnetospheric dynamics. Studying the dynamical organization of macroscopic variability in terms of geomagnetic activity index data by means of complexity measures provides a promising approach for identifying the underlying...

Visible and UV light spectra display striking differences in optical reflectivity for the two types of monatomic steps on copper (111) surfaces. Electronic structure calculations trace these differences to the specific contributions of p(axially) and p(radially) local densities of...
