A grafted polymer layer can be used to prevent the deposition of colloidal particles on a solid surface. This thesis presents Monte Carlo simulations of hard-sphere colloids pushed to a polymer brush under the influence of external fields (e.g. gravity). For weak fields colloids can not penetrate the brush and the eff…

The specific heat at constant pressure of bundles of single-walled carbon nanotubes closed at their ends has been investigated in a temperature interval of 2-120 K. It is found that the curve of heat capacity has features near 5, 36, 80, and 100 K. The experimental results on the heat capacity and the radial thermal e…
Main aim of this thesis is polyphasic characterization of 16 benthic andperiphytic Anabaena strain collected from eight localities in the north part of the Czech Republic in 2010-2011 near the town Sokolov. They were studied using a polyphasic approach, a combination of morphological and molecular approaches. Accordin…

Les microcapsules son particules habitualment esferiques, el diametre de les quals es troba entre 1 i 1000 µm. Estan formades per una paret polimerica que rete al seu interior un altre material amb la finalitat d’aillar-lo del medi, protegir-lo o alliberar-lo de manera controlada. La microencapsulacio s’utilitza en mo…
The experimental values of permeability to gas coefficient P by three gas-penetrants (N2, O2, and CO2), acquired in paper [3], were used for nanocomposites PE/MMT with MMT contents ϕn = 0.008, 0.016, and 0.065. The value P was determined on a baric device [7] at pressure 1-2 MPa and temperature 293K. Nanocomposites sa…
Introduction of different fillers of organic or inorganic origin is one of the most effective and economically profitable methods for enhancement of mechanical properties of polyethylene. Calcium carbonate (CaCO3) is one from such fillers, applied for this purpose for a considerable length of time. It is mainly used a…
Control of nanometre-scale topography of solid surfaces has opened the possibility to tailor the interactions between materials and biomolecules maintaining the biological functions of these molecules, a crucial aspect for diverse biomaterial applications. However, the primary mechanisms that dictate protein adsorptio…

Abstract The reported compound, {Na2[Cu4(HCOO)2(pa)4(CH3OH)] · CH3OH} n (1, H2pa = 2-(hydroxyimino)propionic acid), is a sodium salt of an anionic coordination polymer, comprising rare-topology tetranuclear cluster units, linked through Cu–O bonds to form a polymeric chain. Each cluster unit comprises four Cu2+ cation…

Studies on infinite long monatomic carbon chains based on the hybrid density functional calculations show that the direct band gap can be continuously tuned from 1.58 to 3.8 eV by stretching the chains up to 10% elongation and pairs of sharp peaks locate at the well separated Van Hove singularities in the density of s…
Their intrinsic properties render single quantum systems as ideal tools for quantum enhanced sensing and microscopy. As an additional benefit, their size is typically on an atomic scale which enables sensing with very high spatial resolution. Here, we report on utilizing a single nitrogen vacancy center in nanodiamond…
