We analyzed the results of the sessile drop method to examine experimental data regarding the behavior of liquid droplets on heterogeneous surfaces under the action of a magnetic field, their movement along the surface due to horizontal external forces, and in cases of detachment and dropping of the droplet onto a solid surface, compared to the outcomes of the simulation results obtained using the lattice Boltzmann method within a two-dimensional model. In most cases, there was a satisfactory qualitative agreement observed between the calculated and experimental data. This demonstrates the suitability and effectiveness of the proposed theoretical approach in exploring a broad spectrum of phenomena associated with the contact interaction between liquid and solid heterogeneous phases at both the meso- and macroscopic levels.

Mechanisms of the spatial redistribution of components in a solid target at its ion bombardment have been analyzed theoretically. The influence of the ion mixing, crater shape, and surface roughness on the results of mass spectrometric measurements is simulated as a function of the ion energy. All the above-mentioned factors are shown to have a minimal impact on the sputtering of nano-sized Mo/Si multilayer periodic structures in the ion energy interval of 200-400 eV. Experimental studies of the dopant depth profiles and their comparison with simulation results allowed us to establish the optimum conditions for the mass spectrometric analysis and to measure the real dopant depth profiles with a depth resolution better than 1 nm.

The energy spectra of 46−50 Ti + titanium isotope secondary ions are investigated via steady-state oxygen ion beam sputtering of FeTiO 3 ilmenite and UTi 2 O 6 brannerite samples. The effect of these samples’ phase composition on the formation of specific short-range order statistics on the sputtered surface as well as the influence of various factors on the form of the energy spectra of these matrices are analyzed. The nature of the differences between the energy spectra of Ti + and U + secondary ions is considered. The isotopic composition of the elements in the investigated samples and the correlation between the type of isotope and the nature of its short-range order are analyzed.
The measurements of capillary forces on different diamond-like materials and carbon allotropic modifications taken using a scanning force microscope have been discussed. The amplitude-frequency characteristics of the nanorelief surfaces studied have been widely varied by plasma chemical treatments. The measurements of capillary forces have been compared with the macroscopic values of a wetting angle. It has been shown that a macroscopic wetting angle depends on the averaged surface energy only and is slightly dependent on the nanorelief characteristics, and nanocapillary forces correlate with both surface relief parameters and the local angle of wetting. Criteria for multimeniscus mode of capillary forces measurement in the surface force spectroscopy and the prospects of this procedure application for mapping the real surface energy have been considered in detail.
The article is devoted to the interdisciplinary analysis of the existing institutions for increasing norm-making efficiency, to the definition of organization and legal mechanisms of their relationship. A number of studies, including the one conducted by the author, substantiated the low efficiency of the realization of the transparency principle in conducting anti-corruption expertise, anti-corruption monitoring, and monitoring of the anti-corruption law enforcement. Legal regulation of anti-corruption monitoring in the legislation of the majority of subjects of the Russian Federation comes down to just declarative rules only defining its goals but not the order of conducting. As a result of the analysis the following conclusions have been made: 1) there are serious terminological and methodological differences between the traditional institutions of expertise for legal science and the implemented socio-economic assessment of regulatory impacts; 2) there have been limited formal-legal methods for conducting anti-corruption expert examination and monitoring law enforcement in comparison with the extensive use of sociological and economic methods in assessing the regulatory impacts, which limits the effectiveness of the first two institutions; 3) the above circumstances make an appropriate expansion of the assessment of the need (or lack) for the State interference in not only economic but also in social and political relations; 4) improving information transparency procedures of anti-corruption expertise, anti-corruption monitoring and law enforcement monitoring, formation of interaction mechanisms between the authorities, independent experts, institutions of civil society and business community when all these procedures are conducted, are very important factors for improving investment attractiveness and socio-economic development of Russia.
Matrix effects are analyzed in the secondary ion mass spectra of quartz samples and SiO2 and SiO x films. The spectral relations between Si+, O+, and Si n O m + ions and the corresponding atomic fragments of the matrix are discussed. Previously revealed correlations between the mass spectrum and the structural features of SiO2 and SiO x are analyzed via the kinetic models of ion mixing.
The paper presents an overview and analysis of the most reliable and at the same time rather simple theoretical models describing liquid nanomeniscus geometry and forces occurring between atomic force microscope (AFM) probe and a real surface.There are experimental results in capillary bridge force rupture measured in air, and interaction force under water buffer obtained over surfaces of different nature.It is shown that the theoretical models quite adequately describe the processes observed experimentally and, in particular, bridge ruptures dynamics at the vertical probe withdraw for different speeds.Discussed here are some methodological peculiarities and nanocapillary force spectroscopy diagnostic capabilities for surface energy mapping, prospects of using of a liquid nanomeniscus in local nanochemistry, nanolithography and nano-electrochemistry of a surface.
Silicon-based nanotechnology is highly promising since it is compatible with conventional silicon integrated technique. To date silicon nanowires have been synthesized by varying experimental conditions and a wide range of electronic nanodevices have been demonstrated. A key challenge facing the device realization is the elaboration of a self-assembly nanotechnology enabling the formation of nanoobjects with preset shape and size, crystalline structure, chemical composition, and consequently, physical and chemical properties. To integrate nanodevices into conventional silicon chips, a spatial location and density distribution of nanowires on a chip should be controlled as well. To locate nanowires on desired places with a specific distribution, one should commonly use nanolithography. In this paper we describe a new possibility and its practical realization on silicon for metal-enhanced growth of nanowires with a self-arrangement over the substrate. The proposed physical and mathematical models of the effect is a thermo-stimulated analogue of Liesegang pattern theory. Results of the modeling fit satisfactorily a geometry and nanowire size distribution inside the structure.
The growth, shaping, and doping of silicon nanowires in a catalyst-mediated CVD process are analyzed within the framework of a multilevel modeling procedure. At an atomistic level, surface transport processes and adsorption are considered by MC simulations. At the macroscopic level, numerical solutions of chemical kinetics equations are used to describe nanowire elongation growth and doping. Both atomistic and kinetic considerations complementing each other reveal the importance of surface transport and the role of low-mobility impurities present on the catalyst surface in the nanowire growth process. In particular, a controllable shaping and selective doping of nanowires is possible by means of well-directed effects on the surface transport of both silicon and impurity adatoms. Some nonlinear effects in the growth and doping caused by percolation-related phenomena are demonstrated.
The metal-catalyzed chemical vapor deposition on silicon substrates remains one of the most promising technologies for growing the silicon nanowires up to now. The process involves a wide variety of elementary events (adsorption, desorption, and multicomponent atomic transport with strongly different local mobility, etc.) that take place on the same surface sites and proceed on isolated nano-scaled part of the surface belonging to different individual catalyst particle. In this work, the competition for unoccupied sites during atomic transport under growth doping and percolation-related phenomena on confined parts of surface was treated by the Monte-Carlo simulations. Atomistic simulations were compared with numerical kinetic modeling. Arising non-linear effects that finally lead to specific modes of the nanoobject growth, shaping, and doping were analyzed. By combining different kinds of simulations and experimental results, the proposed strategy provides a better control at atomic scale of nanowire growth. Both atomistic and kinetic considerations supplementing each other reveal the importance of surface transport and the role of surface immobile contaminations in the nanowire growth.
