INFRARED PHOTOLUMINESCENCE SPECTRA OF PBS NANOPARTICLES PREPARED BY LANGMUIR–BLODGETT AND LASER ABLATION METHODS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
We optimized the optical setup originally designed for the photoluminescence measurements in the spectral range 400‒1100 nm. New design extends the spectral range into the near infrared region 900‒1700 nm and allows the ...
OBLIQUE MAGNETIC FIELDS AND THE ROLE OF FRAME DRAGGING NEAR ROTATING BLACK HOLE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
Magnetic null points can develop near the ergosphere boundary of a rotating black hole by the combined effects of strong gravitational field and the frame-dragging mechanism. The induced electric component does not vanish ...
INFLUENCE OF SUBSTRATE THICKNESS ON DIFFUSE COPLANAR SURFACE BARRIER DISCHARGE PROPERTIES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
In presented work the influence of dielectric barrier thickness on the parameters of Diffuse Coplanar Surface Barrier Discharge was investigated. The discharge was operated at atmospheric pressure laboratory air. The ...
DEPOSITION CARBON NANOSTRUCTURES BY SURFATRON GENERATED DISCHARGE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
Carbon nanostructures were deposited by surface wave discharge using various Ar/CH4/ CO2 gas mixture ratios. The morphology was controlled by adjusting of gas concentration and was investigated by scanning electron microscopy ...
SHAPE OF A NUCLEUS GROWING ON STRONGLY CURVED SURFACE OF A NANOFIBER
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
The equilibrium shape of a critical nucleus has strong impact on important parameters of nucleation theory, such as nucleation rate. While on the flat substrate the growing nucleus has a shape of a spherical cap, a shape ...
AUTOMORPHISMS OF ALGEBRAS AND ORTHOGONAL POLYNOMIALS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
Suitable automorphisms together with complete classification of representations of some algebras can be used to generate some sets of orthogonal polynomials “at no cost”. This is also the case of nonstandard Klimyk-Gavrilik ...
EFFECTIVE USE OF ROTARY FURNACE SHELL HEAT
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
Significant proportion of the total energy expenditure for the heat treatment of raw materials are heat losses through the shell of rotary furnace. Currently, the waste heat is not used in any way and escapes into the ...
ANALYSIS OF MECHANICAL PROPERTIES OF HYDROTHERMALLY CURED HIGH STRENGTH CEMENT MATRIX FOR TEXTILE REINFORCED CONCRETE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
The main objective of this article is to describe the influence of hydrothermal curing conditions in an autoclave device (different pressure and temperature), which took place at various ages of a fresh mixture (cement ...
TREATMENT OF NATURAL GAS BY ADSORPTION OF CO2
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
Apart from burning, one of the possible uses of natural gas is as a fuel for motor vehicles. There are two types of fuel from natural gas — CNG (Compressed Natural Gas) or LNG (Liquefied Natural Gas). Liquefaction of natural ...
UNSTEADY FLOW OF THIXOTROPIC COLLAGEN SUBSTANCE IN PIPES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
Unsteady flow of thixotropic liquid in pipes is solved by 1D and 2D numerical methods using the same constitutive equation — the only difference is in the radial diffusion of the structural parameter. Comparison shows that ...
