The point-contact spectra of the Andreev reflection dV / dI curves of the superconducting rare-earth nickel borocarbide ErNi₂B₂C (Tc≈11K) have been analyzed in the «one-gap» and «two-gap» approximations using the generalized Blonder–Tinkham–Klapwijk model and the Beloborod'ko model allowing for the pair-breaking effec…
The density distributions of water molecules and hydrogen bond in a specific nanocapsule at different temperatures were investigated by molecular dynamics simulation. We also analysed the intra-molecule angle and orientation of water molecules. The result indicates that, due to the confinement of carbon nanocapsule, w…
The local dynamical features of a PEO melt studied by MD simulations are compared to two model chain systems, namely the well-known Rouse model as well as the semiflexible chain model (SFCM) that additionally incorporates chain stiffness. Apart from the analysis of rather general quantities such as the mean square dis…
In this paper a Monte Carlo method has been used to calculate the phonon images of a number of semiconductor cubic crystals from III-V and II-VI groups (higher symmetry) and orthorhombic crystals (lower symmetry). An algorithms a MATLAB codes has been prepared for the calculation of phase velocities, slowness surfaces…
We consider a model consisting of a self-avoiding polygon occupying a variable density of the sites of a square lattice. A fixed energy is associated with each 90 ◦-bend of the polygon. We use a grand canonical ensemble, introducing parameters µ and β to control average density and average (total) energy of the polygo…

A novel drug carrier based on SiO2-coated silver nanoparticle aggregates and antitumor drug is successfully synthesized. The surface-enhanced Raman scattering (SERS) spectra of the antitumor drug in living cells are obtained. By using silver nano-aggregates as SERS substrates instead of dispersed silver particles, a g…
The present contribution deals with the model-based analysis, the model reduction and the control of polymer electrolyte membrane fuel cells (PEMFCs).In the first part of this work a bifurcation analysis of a PEM fuel cell under two-phase conditions, i.e. the parallel presence of liquid water and water vapor inside th…
The formation of nitrogen oxides (NOx) in combustion systems is an important environmental concern. The control of NOx emissions and modern reduction techniques is based on worldwide investigations performed in this field. In this chapter, developments in the understanding of nitrogen chemistry in flames during the pa…
A novel direct writing technique using submicron-diameter fibers is presented. This technique adopts contact mode in the process of writing, and submicron lines with different widths have been obtained. Experimental results demonstrate that the resolution of this technique can be smaller than the exposure wavelength o…
Defined nanoparticle cluster arrays (NCAs) with total lateral dimensions of up to 25.4 μm × 25.4 μm have been fabricated on top of a 10 nm thin gold film using template-guided self-assembly. This approach provides precise control of the structural parameters in the arrays, allowing a systematic variation of the averag…

The paper presents a single-sided double-S left-handed metamaterial structure in the X-band. The left-handed property of the new metamaterial has been verified by numerical simulation and experiment. Experimental results show the existence of the negative refraction within the same frequency band as indicated by the s…
Flexible silicon/single-walled carbon nanotube (Si/SWCNT) composite paper was prepared using the pulsed laser deposition (PLD) method to deposit Si onto SWCNT paper. In the composite, Si mainly shows nanoworm-like morphology. Increasing deposition time results in an increased amount of Si microspheres. Electrochemical…
The crystal structure of the new Tb 13 ZnSn 13 compound (space group I4/mmm, a = 11.599(2) , c = 27.247(5) ) was determined by X-ray single crystal diffraction. The composition was confirmed by EDX analysis. The compound crystallizes in its own structure type, which can be built from fragments that are related to the…
The mechanical properties of post-consumer composites of expanded polystyrene and sawdust of Pinus elliottii were analyzed in order to verify the use of such waste in obtaining new materials. The expanded polystyrene (EPS) has low market value for the recycling and other waste sawdust is abundant in the region northea…
Single crystals in the form of cubes, tetrahedra or combinations of cubes and tetrahedra with sillenite structure in the Bi 2 O 3 -SiO 2 -MnO 2 system, as well as bulk crystals (Bi 24 Ge 2 O 40 used as a seed crystal) in the Bi 2 O 3 -SiO 2 -V 2 O 5 system, have been grown by the hydrothermal method.The results of the…
Recently, with the high performance and efficiency of machine, there have been required the multi-functions in various machine parts, such as the heat resistance, the abrasion resistance and the stress resistance as well as the strength. Fatigue crack growth tests were carried out to investigate the fatigue characteri…
The photocatalytic hydrogenation of CO2 over TiO2 bicrystalline dehydrated nanoribbons (DNR) was investigated at normal temperature and pressure. Under UV irradiation, generation of methane via CO2 hydrogenation was observed. Quantitative structure-activity relationship (QSAR) of photecatalysts and methane production…
