The present work encompasses results on NDs and diamond coatings for life sciences, tissue engineering, and regenerative medicine. First, the interaction of functionalized NDs with human osteoblast cells in vitro will be presented. The influence of NDs on the cell viability was measured by mitochondrial metabolic acti…
Дисертаційну роботу присвячено встановленню зв'язку між фізико-хімічними властивостями нанорозмірних Pd, Pt-вмісних матеріалів на основі SnO2, їх каталітичною активністю в реакції окиснення СН4 та характеристиками створених на їх основі адсорбційно-напівпровідникових сенсорів метану. Золь-гель методом синтезовано нано…
The aim of this work was to analyze mortar from Petschek villa, XRD and SEM-EDX analyzes have been proposed, which results in the characterization of aggregate and mortar binders. The analyses proved gypsum plaster with surface paint.
From the perspective of the immune system, nanomaterials (NMs) represent invading agents. Macrophages are immune cells residing in all organs and tissues as the first line of defense. Interactions of macrophages with NMs can determine the fate of NMs as well as their potential toxic effects. In the present study, we c…
Citrate solution method is very suitable for preparation of multielement perovskites in the form of powders and thin layers. In this study, we demonstrate the feasibility of the method for deposition of perovskite-based materials on conventional γ-alumina and industrial metal carriers. A perovskite-based entity of La(…

The effects of degassing, holding time and melt additions (Sr, Sr + Ti, Ti, B and B + Sr) on the quality of A356 melts were examined. A total of 120 reduced pressure test samples were collected. Pores in these samples were analyzed via digital image processing to determine the number density of pores as well as the st…
Cathodoluminescence is a phenomenon of some materials which is generated by electron beam interaction with a luminescence matter. The result of this interaction is production of the photons of infrared, visible and ultraviolet parts of electromagnetic spectrum. The technique to release the photons from luminescence ma…
Pb(Zr, Ti)O3 (PTZ) is a ferroelectric material interesting for its high dielectric constatn and piezoelectric response. PZT thin films can be prepared by various method, e.g. pulsed laser depozition, chemical vapon deposition, sol-gel and, most frequently, sputtering. Though the magnetron sputtering is used more frequ…

This work deals with growth of KCaI3:Eu and KSr2I5:Eu by micro-pulling-down method. Polycrystalline ingots with compositions of KCa0.97Eu0.03I3 and KSr1.92Eu0.08I5:Eu were presynthesized from stoichiometric mixtures of the binary iodides and used as starting materials for growth experiments. Scintillation light output…

The Laboratories of Institute of Scientific Instruments of the Academy of Sciences of the Czech Republic (ISI) are equipped with cutting-edge scanning electron microscopes that allow studying a wide range of materials science and biological samples. One of these is the Magellan 400L which offers a resolution of less t…
Heat flux magnitude and distribution over first wall and plasma facing components is a key issue for next step fusion devices in order to avoid damage of inner vessel components and secure reliable operation. Radial profiles of parallel heat\nflux in present tokamaks and their scaling towards next step devices are thu…
In this study, effects of the TRISO packing fractions of extended burn up of CANDU reactor were investigated. The prospects of utilization of TRISO fuel made of reactor grade plutonium mixed natural uranium in CANDU reactors were performed. TRISO fuels particles were imbedded Simple Cubic (SC), Body Centered Cubic (BC…
We present the spectroscopic characterization and laser operation of a 2%at. Yb doped Gd3(Al0.5Ga0.5)5O12 (Yb:GAGG) crystal, grown with the Czochralski method. We determined the absorption and the emission spectrum, the upper level lifetime, and the thermal conductivity. The internal disordered structure determines a…
Electrospun nanofibres (NFs), with high surface area to volume ration and structures mimicking natural extracellular matrix, have gained popularity as cell carrier systems for regenerative medicine. However, many polymers used for NFs preparation, do not have the desired surface properties to be used as biomaterials i…
Energetic Particle driven plasma modes resulting from interaction of shear Alfvén waves with fast ions generated by fusion reactions, NBI or ICRH heating are capable of causing fast particle losses, negatively affecting the plasma performance or having detrimental effects on plasma-facing components or vacuum vessel.…
