Abstract: The improvement of hydrogen storage properties of ball-milled Mg-Al-Ti-Zr-C composite was studied in this paper. It has been previously shown, that the addition of Ti, Zr, Al and C improves storage properties of Mg. [..] Read more

Abstract: Here we present a simple analytical model describing electroabsorption of semiconductor nanocuboids in a wide range of electric field strengths. Using the developed model, we study all the basic electroabsorption effects, including the Stark effect, the Franz-Keldysh effect, and the field-induced broadening of the spectral lines in the nanocrystals spectra.

Abstract: This paper describes the measurement of the electric wind phenomenon via using Global Imaging methods. Electric wind can be described as movement of the air generated by free ions metal object (in our case electrodes) which are powered by high voltage. [..] Read more

Abstract: Carbon-based nanolayers have been attracting much attention due to their excellent low-friction properties, their high hardness and their good wear resistance. In this work we present the results of material research aimed at reducing the friction of the functional surfaces of titanium implants, and thus extending their lifetime to reoperation.

Abstract: The interest in ZnO (zinc oxide) nanoparticles is increasing due to low cost of their processing as well as the ability of fabricating ZnO nanostructures with controllable morphology such as size, shape and orientation. Our choice of method of the preparation of the nanostructured thin ZnO layers is the hydrothermal growth of ZnO nanorods on glass substrates coated by the nucleation layer deposited by the reactive magnetron sputtering.

Abstract: The Density Functional study on Hydrogen Adsorption on Silicon Carbide Nanosheet has been investigated. All calculations have been performed with density functional theory (DFT) , within the plane-wave pseudopotential approach as implemented in the Quantum ESPRESSO Simulation Package. [..] Read more

Abstract: Analysis of the nanoscale phases which appear on the surface Fe-6Si samples were carried out after the various treatments – grinding and etching, annealing, and water jet abrasion. The basic information on structure, chemical and phase composition was obtained by X-Ray Powder Diffraction (XRD), Scanning Electron Microscopy with EDX, Glow Discharge Optical Emission Spectrometry (GDOES), Mössbauer Spectroscopy and X-ray Photoelectron Spectrometry (XPS).

Abstract: Titanium and its alloys attract much attention due to their low specific weight, good corrosion resistance, high toughness, high yield strength and efficient biocompatibility. However, these materials have poor wear resistance, high friction and low hardness. [..] Read more

Abstract: Light-sensitive polymer materials with embedded chromone dyes are promising candidates for multi-layer fluorescent disks for archival storage of information. The recording is based on two-photon-induced phototransformation and the signal readout is due to single-photon-induced luminescence. [..] Read more

Abstract: In this study we present calculation of molecular mechanic and electronic transport properties of epitaxially grown graphene on step-shaped SiC substrate. We simulated two types of structural arrangements. [..] Read more

Abstract: ZnO is an attractive wide band gap semiconductor with large exciton binding energy, high refractive index, high biocompatibility and diversety of nanostructure shapes which makes it suitable for many applications in the optoelectronic devices, optical sensors, and biosensors. We study the effect of hydrogen plasma treatment of the nominally undoped ZnO thin film deposited by DC reactive magnetron sputtering of Zn target in the gas mixture of argon and oxygen plasma.

Abstract: Laboratory-prepared particles of nanocellulose were added to acrylic coating material in order to increase the strength of cotton canvas. The size of the cellulose nanoparticles was determined using a Zetasizer device. [..] Read more

Abstract: In this work, nanotechnologies including electrospun nanofibers and nanoparticles were implemented for acid dye removal from simulated wastewater. Dynamic sorption properties of polyamide 6 nanofibrous membrane (PNM) were investigated, Titanium dioxide (TiO2) nanoparticles deposition was applied as surface modification method for PNM, and UV light was applied during the dynamic sorption process of C.

Abstract: Development of new materials is still growing up. The relatively new materials are nanofibers membranes. [..] Read more

Abstract: Li-ion batteries (LIBs) are widely used as portable power sources. The development of new electrode materials for LIBs is an important challenge for material science. [..] Read more

Abstract: Migration of zero valent iron in the subsurface is a task solved in the long term from different points of view at many workplaces. Experimental equipment in these workplaces mostly enables only one-dimensional assignments (laboratory columns) to be studied in different orders with various levels of detection of migrant substances.

Abstract: Textiles perform an important function of protecting humans from extreme conditions. For this function, the efficacy of the fabric is a very important parameter. [..] Read more

Abstract: A method for on-line measurement of photocatalytic activity of powdered samples by UV-Vis spectrometry is demonstrated. It enables photocatalytic reaction to be monitored directly in the cuvette which also serves as photocatalytic reactor. [..] Read more

Abstract: Transparent coatings of TiO2-SiO2 nanocomposite were developed to be applied on building facades in order to prevent growth of microorganisms and thus to improve urban building sustainability. Structure and texture characteristics of the prepared nanocomposites were determined by electron microscopy (SEM, TEM + EDS), their photocatalytic activity was quantified by testing self-cleaning ability and antimicrobial activity.
