Acoustic – Electromagnetic Transformation in Magnetic Nanofluids

Sokolov V.V., Moscow State University of Instrument Engineering and Computer Science, RU

Here is examined the acoustic – electromagnetic transformation accompanying the propagation of sound wave through a magnetic nanofluid.The magnetic nanofluid was placed in the cylindrical resonator. An external magnetic field was applied along an axis [...]

Dynamics of carbon nanopillar growth on bulk and thin substrates irradiated by a focused electron beam

Zhdanov G.S., Manukhova A.D., Lozhkin M.S., St. Petersburg State University, RU

Here we compare successive stages of carbon nanopillar growth on various substrates irradiated by a 20keV electron beam focused to a spot of 1 nm diameter. The hydrocarbon molecules present in the residual atmosphere of [...]

Femtosecond transient absorption of plasmonic gold nanoparticles embedded in mesoporous TiO2 matrix: electron injection study

Aiboushev A., Kostrov A., Gostev F., Nadtochenko V., N.N. Semenov Institute of Chemical Physics Russian Academy of Sciences, RU

Gold nanoparticles (AuNP) embedded in mesoporous films of wide band gap semiconductors such as TiO2 are used for promising applications in solar cells, visible light-sensitive photocatalysts, and biosensors developed on the basis of the surface [...]

Computer Simulation of Phase Transitions and Orientational Order in Low-and High-molecular Ferroelectric Nano-Systems

Maksimov A.V., Maksimova O.G., Maksimova O.G., Petrova T.O., Nastuljavichus A.A., Baruzdina O.S., Cherepovets State University, RU

A computer simulation of processes of polarization of the low-and high-molecular ferroelectric systems has been made by the Monte Carlo method. The developed program complex has been tested by the comparison with analytical calculations and [...]

Simulation of water adsorption on a diamond (100) surface containing a vacancy defect

Lvova N.A., Lvova N.А., Ananina O.Yu., Lvova N.A., Lvova N.А., Federal State Bugetary Institution, RU

Water is one of the most important adsorbates interacting with the diamond surface. In particular, the presence of -H and -OH on the surface affects the physical and chemical properties of nanocrystalline diamond particles, which [...]

Ultrasound absorption in magnetic nanofluids

Sokolov V.V., Nadvoretskiy V.V., Moscow State University of Instrument Engineering and Computer Science, RU

Mechanisms of ultrasound absorption in magnetic nanofluids at the absence of external magnetic field are theoretically studied in the first part of the paper. The novel magnetodynamic mechanism of ultrasound absorption is introduced – it [...]

Effective Viscosity of the nanofluids: Experimental studying and molecular dynamics simulation

Rudyak V.Ya., Dimov S.V., Krasnolutsky S.L., Ivanov D.A., Novosibirsk State University of Architecture & Civil Engineering, RU

The studying the effective viscosity coefficient of the nanofluids is the object of present paper. Experimentally the viscosity of the nanofluids on basis of ethylene glycol and SiO2 nanoparticles was studied. It was shown that [...]

Dendritic Oligoarilsilanes as Effective Nanostructured Luminophores for Spectral Shifters and Plastic Scintillators

Ponomarenko S.A., Borshchev O.V., Luponosov Y.N., Surin N.M., Muzafarov A.M., Institute of Synthetic Polymeric Materials of Russian Academy of Sciences, RU

During the last years the number of light-harvesting luminescent dendrimers has increased rapidly. One of the most interesting features of the dendrimers is a possibility of incorporation of different chromophores within one dendritic molecule that [...]
