Existing metamodels are not able to effectively capture the knowledge of multidimensional cyber-physical domains. In order to contribute to this area the approach for development of metamodels for modelling the multidimensional cyber-physical systems is considered in the paper. The geometrical meta-metamodel, allowing to link the physical properties of domains with its spatial structure, is proposed. The implementation of the metamodelling approach in the Visual Environment for Cyber-Physical Modelling is considered. The example of using the geometrical meta-metamodel for metamaterials design is given. Investigation, modeling, design and implementation of cyber-physical systems have to be considered as a new and essential part of cyber worlds. © 2013 IEEE.

The paper considers Computer-Aided Design (CAD) system FORTU-FEM, which mathematical base is the Finite-Element Method (FEM). Unlike other CAD systems, which does not allow to their users to change the schema of calculation, FORTU-FEM has an open architecture and allows to engineers to develop various methods for design and analysis of non-standard mechanical constructions. Applications of FORTU-FEM for design of non-standard constructions from elastomers, calculation of the tensional and the deformed states of such the constructions are considered. © 2014 IEEE.

The internal emission of hot electrons from a metal (Pd) surface is studied. The electrons gain energy from chemical atomic collisions with the thermal energy hydrogen atoms or with H2 + O2 molecules. A Pd(15 nm)/n-Si(111) nano-Schottky diode is used as a detector of hot electrons in which chemicurrents (and chemo-emf) are generated. The efficiency of entering of chemo-electrons into the external circuit per act of interaction (or per product molecule) is determined. © 2012 Pleiades Publishing, Ltd.

Nonthermal (nonequilibrium) generation of hot electrons (electron-hole pairs) in palladium has been observed due to the chemical energy transfer to electrons in the metal during the exothermal reaction of hydrogen peroxide decomposition at the aqueous H2O2 solution-palladium interface. The yield of electronhole pairs (per decomposed peroxide molecule) in the metal has been determined. © 2015, Pleiades Publishing, Ltd.

The effects of excitation of the transverse chemovoltage (chemo-emf) and nonequilibrium chemoconductivity in a CdTe film obtained by the “oblique deposition” method upon its interaction with atomic hydrogen are studied. Both effects are related to the nonthermal generation of electron-hole pairs in the semiconductor film caused by the energy released in chemical events of interaction between H atoms and the CdTe surface (the adsorption of atoms and formation of H2 molecules). The chemovoltage and chemoconductivity kinetics and the dependence of the steady-state values of the effects on the atomic-flux density and sample temperature are studied. It is established that the events of both H-atom adsorption and their recombination participate in the process of (e−h) pair generation. Analytical expressions for the chemovoltage and chemoconductivity are obtained. The numerical values of the parameters of interaction between H atoms and the CdTe surface and the effectiveness of (e−h) pair generation are estimated. © 2015, Pleiades Publishing, Ltd.

Use of GaAs and GaP porous plates is proposed as a replacement of activated carbon electrodes for supercapacitors. Porous electrodes are prepared by electrochemical etching. Description of the production technique of supercapacitors based on porous semiconductors A3B5 is presented. Area of the porous surface is defined by gas adsorption method. The method for calculation of supercapacitor capacitance created on GaAs and GaP porous plates is described. © 2015 Sumy State University.

The process of chemical-energy transformation into electricity is studied on the surface of a semiconductor structure (SiC-based nanosized p-n junctions). The energy transformation occurs due to the interaction of hydrogen and oxygen atoms, as well as mixtures of H + O and CH3 + H with the surface and subsequent separation of the electron-hole pairs by the electric field of the p-n junction. The top p-layer of a SiC-based structure has a thickness of about 30 nm. It is shown that, in an open circuit, the chemo emf has reached 3 mV and the short circuit chemicurrent 320 nA. © 2013 Pleiades Publishing, Ltd.

We propose an original method for producing indium oxide nanotubes embedded in a porous InP surface. Annealing of porous InP samples obtained by electrochemical etching is performed in a flux of atomic oxygen. After annealing the inner surface of the walls of each pore was covered with oxygen throughout its length from the base (indium phosphide column) to the sample surface forming oxygen-containing nanotubes which mimic the shape of pores. Chemical composition of the surface of the obtained samples was studied using the method of energy dispersive X-ray analysis (EDAX). Structure of the obtained samples was also studied by the X-ray diffraction method. © 2015 Sumy State University.

It is found that the chemical energy released in the recombination of monatomic hydrogen on the surface of selenium is efficiently transferred to the electron subsystem of the crystal, which is manifested in the generation of electron-hole pairs and excitation of steady-state chemicurrent. Both the stage of adsorption and the stage of association of the hydrogen atoms on the surface contribute to the effect. The atomic hydrogen-selenium system is a very simple one and can be used as a model system in the search for semiconductors and chemical reactions suitable for direct conversion of the chemical energy into electricity. © 2012 Pleiades Publishing, Ltd.
