Заглавие : Synthesis of monodisperse submicron spherical poly(methylmethacrylate) particles and the molecular dynamics simulation
Место публикации : Colloid J.: MAIK Nauka-Interperiodica / Springer, 2014. - Vol. 76, Is. 1. - P.113-119. - ISSN 1061-933X, DOI 10.1134/S1061933X14010128. - ISSN 1608-3067

Аннотация: The molecular-dynamics method has been used to determine the conformational states of poly(methyl methacrylate) chains in a medium composed of water and a monomer (methyl methacrylate). Experimentally detected spherical particles resulting from polymerization have been found to take the form of droplet-type aggregates containing several chains, with the water and monomer concentrations in the aggregates differing from those in the dispersion medium. It has been shown that the methyl methacrylate concentration in an initial reaction mixture of about 20% is optimal for the formation of spherical droplet-type aggregates. It has been experimentally established that spherical poly(methyl methacrylate) particles with a narrow size distribution are formed at a methyl methacrylate concentration of ≈23%.

Аннотация: Features of the formation of periodic 2D and 3D opal-like structures depending on the conditions of deposition have been investigated in this work. The subject of the experiments is aqueous dispersions of poly(methyl methacrylate) submicron particles with a narrow size distribution. The particles are precipitated by sedimentation, centrifugation, and the meniscus method. The samples are studied using electron microscopes. Significant morphological differences in periodic structures obtained by various methods are found. © 2016, Pleiades Publishing, Ltd.

Аннотация: Morphological parameters, reflection spectra, IR absorption spectra, and glass transition temperatures of submicron-sized spheres of poly(methyl methacrylate) (PMMA) formed in a water-acetone dispersion medium were studied in comparison with similar spheres obtained in distilled water. Dependence of a shrinkage degree of the submicrospheres on the concentration of acetone in water is studied. Features of the formation of periodic structures based on the water-acetone dispersions of PMMA in four different ways are considered. 2D (photonic crystal films) and 3D (artificial and inverse opals) resonance structures were obtained.

Заглавие : Self-trapping of nanoparticles by bound states in the continuum
Место публикации : Phys. Rev. B. - 2022. - Vol. 106, Is. 16. - Ст.165430. - ISSN 24699950 (ISSN), DOI 10.1103/PhysRevB.106.165430

Аннотация: In the first tutorial part of the paper, we show that equilibrium positions of small dielectric particles inside the Fabry-Perot resonator (FPR) are sensitive to a frequency of incident electromagnetic wave and size of particle. That elucidates basic principles of resonant trapping of nanoparticles by excitation of high-Q resonances of FPR. In the second part, we consider a long dielectric cylinder with submicron radius (primary cylinder) integrated into a metallic waveguide which supports symmetry-protected bound states in the continuum (BICs). We consider the case of a slightly shifted cylinder relative to the axis of symmetry of a waveguide that controls the Q factor of quasi-BIC. Then, the extra nanoparticle perturbs quasi-BIC as dependent on the size of the nanoparticle and position relative to the primary cylinder. An interplay between the resonant width of quasi-BIC and a degree of frequency perturbation defines whether a dragging nanoparticle is terminated at a surface of the primary cylinder for an ultrasmall size of nanoparticles or at the definite distances from the cylinder for the larger size of nanoparticles. Thereby, we demonstrate a paradigm of resonant self-trapping and sorting of nanoparticles by use of quasi-BICs. We also show extremal sensitivity of self-trapping to the frequency of an electromagnetic (EM) wave propagating over waveguide.

Заглавие : Relaxation of the trapped magnetic flux in a mesoscopic HTS with artificial pinning in the form of submicron holes

Аннотация: Vortex relaxation has been studied in a microsized HTS with various distributions of artificial pinning in the form of submicro-holes. It has been shown that, in some cases, for a superconductor with dimensions up to several micrometers, the time dependences of the trapped magnetic field do not correspond with the collective creep model. The dependences of the trapped-field relaxation rate and vortex activation energy on the magnetizing field (up to 0.5 T) and temperature (up to 50 K) have been obtained. It has been shown that the presence of submicro-holes slightly increases the relaxation rate, mainly due to the decrease in the number of random nanosized pinning centers.
