Abstract: The relation between plasma temperature and properties of graphene nanosheet layer deposited on Si/SiO2 substrate by decomposition of ethanol in microwave plasma torch discharge at atmospheric pressure was investigated in dependence on delivered microwave power and gas flow rates. Plasma modelling was carried out using COMSOL Multiphysics software with delivered microwave power, gas flow rates and experimental reactor geometry as input parameters. [..] Read more

Abstract: We report the fabrication of thick nanoporous oxide films on stainless steel (SS) foils via long-term constant-potential anodization at room temperature. The anodization potential of 50 V was employed for 1, 2 and 3 h, respectively to form the anodic films with different thickness. [..] Read more

Abstract: Magnetic nanoparticles experience magnetic force under the magnetic field. The magnetic force can be measured as the magnetic weight of the magnetic nanoparticle sample with a conventional electronic balance. [..] Read more

Abstract: In this contribution, magnetic Fe2O3 nanoparticles (MNPs) were successfully incorporated into the polyvinyl butyral (PVB) nanofibrous membranes using the electrospinning process. The effects of the MNP concentration on the morphology of the nanofibres and their magnetic properties were investigated. [..] Read more

Abstract: The development of electronic technologies and the requirement for high-speed electronic systems and devices have led to an increased improvement in the performance of electronic and telecommunication devices (mobile phones, wireless or navigation systems etc.). Long-term exposure to electromagnetic (EM) fields poses serious risks to human health (EM pollution). [..] Read more

Abstract: In this work, a stable suspension recipe and the optimal mode for the EPD process are presented. The possibility of precision control of the thermite material composition in electrophoretic deposition technology is considered. [..] Read more

Abstract: This study deals with the effect of star-like zinc oxide (ZnO) filler addition into poly(vinylidene fluoride) (PVDF) matrix on its structural and physical properties with the consequences to mechanical energy harvesting performance. In this case, the microwave-assisted synthesis was optimized for the preparation of unique star-like shape of ZnO particles. [..] Read more

Abstract: ZnO nanorods have attracted increasing interest in recent years due to their potential in optoelectronic applications. The lack of p-type ZnO emphasizes the importance of rectifying junctions realized on other p-type materials. [..] Read more

Abstract: Perovskites are one of the most intensively studied photovoltaic materials nowadays. Microscopic studies can provide useful information about material roughness, conductivity, structure, mechanical and opto-electronic properties as well as about kinetic effects from short to long time scale for understanding and improving the photovoltaic performance.

Abstract: On the basis of arc metal deposition process the technology for carbon nanotubes (CNT) addition to metal was developed. It uses extruded metal rods with CNT’s as additional material. [..] Read more

Abstract: Polyester urethane polymer was synthesized as linked biocompatible poly (lactide)/poly (ethylene oxide) polymers. The bulk polymer was subsequently used as precursor material for plasma assisted vapour thermal deposition of thin plasma polymer films under varying RF discharge power. [..] Read more

Abstract: An in situ investigation has been carried out by X-ray diffraction of the evolution of the crystallite size and the microstrain of low-temperature annealed commercially pure titanium grade 2 in the state after machining and polishing. Annealing was performed in vacuum at a temperature of 300, 400 and 500°C, with various dwell times. [..] Read more

Abstract: A novel two-step pathway towards sulphur-doped graphitic carbon nitride (CN) was hypothesized and practically tested. As a result of that, three new materials with the different content of sulphur (up to 0.023 wt.%) were synthesized. [..] Read more

Abstract: PMMA / PTFE optical fibers with increasing lateral emission were coated with titanium nanolayer using low-temperature plasma. We investigated how this nanolayer affected the spectrum of emission when VIS LED and UVA LED light sources were used. [..] Read more

Abstract: Ecological concern has recently resulted in a natural sources which are rich in cellulose, cheap and provide good prospective as reinforcements fillers in polymer matrix composites as recyclability and environmental safety. Rice husk is a cellulose-based fibrous material and a waste product of the rice processing industry. [..] Read more

Abstract: Photocatalytic reduction of carbon dioxide (CO2) is a challenging reaction attracting a lot of attention. Finding a novel, efficient and relatively cheap photocatalyst is the goal of many research teams all over the world. [..] Read more

Abstract: Agarose hydrogel was used as the transport medium for the investigation of the diffusion of lignohumate through plant cuticle. The cuticles were isolated from Prunus laurocerasus by two different methods: chemical and enzymatic. [..] Read more

Abstract: Thermal decomposition of complex salts [M(NH3)4]A (M = Pt, Pd; A = CrO4, Cr2O7) in oxygen atmosphere goes through the stage of formation of the phase MCrO2 with delafossite structure and it’s further decomposition and formation of the chromium oxide(III) and monometallic platinum or palladium. Thermal decomposition of complex salts [M(NH3)4]A (M = Pt, Pd; A = CrO4, Cr2O7) in hydrogen atmosphere proceeds with partial reduction of chromium to an metallic state and the formation of a metal solid solution MxCr1-x (M = Pt, Pd) with a chromium content up to 22 at.% and a chromium oxide(III).
