Synthetic polycrystalline diamond films are routinely grown over the world not only for basic research but also for industrial uses in many different fields including optics and photonics. Optically tailored diamond films are usually grown by microwave plasma chemical vapor deposition (MWCVD) reactors. Here we will pr…
Here we report photovoltaic-electrolysis method for reductive preparation of various nano-structures of metals like tellurium, silver, etc., without the need of any other chemical reduction agents, like borohydride.
The presence of Edge Localized Modes (ELMs) in large tokamak devices like ITER can lead to exposure of plasma facing components (PFCs) to extremely high power fluxes and consequential melting of PFCs. A very promising method for ELM mitigation and/or suppression is the application of non-axisymmetric magnetic fields,…
Electrorheological (ER) fluids are smart materials that experience an abrupt increase of viscosity when subjected to an external electric field applied perpendicular to the flow field. The reversible change in viscosity turns them suitable for applications in mechanical devices, like brakes, damping systems and clutch…
Through-the-lens secondary electron detector (TLD) works as a bandpass energy filter in a field emission gun SEM Magellan 400.
Předneseno na: 20th International Summer School Vacuum, Electron and Ion Technologies (VEIT2017), Sozopol, 25-29.09.2017.\nThe Langmuir probe is among the most frequently used tools in evaluating the plasma potential, electron temperature and density in the vicinity of the last closed flux surface (LCFS) and in the sc…
In Vertical Gradient Freeze growth of GaAs, the solid-liquid interface shape and subsequently the crystal quality can be improved by forced convection via travelling magnetic fields (TMFs). At present, general methodology to identify the relation and optimize magnetic and crystal growth parameters doesn’t exist. In th…

This research is focused on the electrochemical synthesis and characterization of\npoly(methylene blue) (pMB). Two different carbon-based electrode substrates, basal plane\nhighly oriented pyrolytic graphite (HOPG) and pencil graphite electrode (PGE), have been\nmodified by conductive film of pMB. Electrochemical prop…
Synthetic strategies to partially fluorinated polyaromatics by photocyclization were examined, leading to both 1,2,3,4-tetrafluoro[6]helicene (1) and 1,2,3,4,13,14,15,16-octafluoro[6]helicene (2), and to 1,2,3,4-tetrafluoro[5]phenacene (3) and 1,2,3,4-tetrafluoro[6]phenacene (4). Thin films of the prepared compounds w…
This book introduces and describes in detail the research and development in thin film scintillators, glass ceramics, as well as nanocomposite and optical ceramics prepared by spark plasma sintering. It also features example of an in-depth study of a ZnO-based powder phosphor material. Both technology description and…
Properties of milling-induced high-pressure B phase in Y2O3 and W-Y2O3 powders were studied by differential thermal analysis and X-Ray diffraction. It was found that phase stability strongly depends on the heating rate and holding time.

Homogeneous dispersions of MoSe2 nanoparticles of various concentrations in the polycrystalline Bi2Se3 matrix were prepared and their pellets were produced by the conventional hot-pressing method. The transport and thermoelectric properties were studied
Global Interest In the sustalnable development has become the main topic of discussion, recently. In transport Infrastructure sector, many research from novel materlal to technological development, driven toward the economic stimulation and promoting the reduction on environmental impact, are highly encouraged. This t…
The device is designed to accurately measure the depth of etching in a deep reactive etching system. Measurements can be made in real time, allowing you to stop the etching process after reaching a certain depth of etching, thereby improving the production of micro and nanostructures.

The purope of this study was to investigate the effect of silica-supported 12-phosphomolybdic acids in which molybdenum is partially substituted for vanadium on deep oxidation of ethanol and the effect of introduction of palladium to the catalysts on their activity and selectivity in total ethanol oxidation.
Summarizing, it was shown that metal particle size is a key factor that influences the physicochemical properties of the catalysts and consequently their catalytic performance. Moreover, it demonstrated that by employing a proper method of catalyst preparation (especially the way of noble metal introduction), highly a…
