Characterization of hydrogenated silicon thin films and diode structures with integrated germanium nanoparticles
Stuchlík, J.; Fajgar, R.; Remeš, Z.; Kupčík, Jaroslav; Stuchlíková, H.
2018 - anglický
P-I-N diode structures based on the thin films of amorphous hydrogenated silicon (a-Si: H) deposited by Plasma Enhanced Chemical Vapor Deposition (PECVD) technique were prepared with embedded Si and Ge nanoparticles. The Reactive Laser Ablation (RLA) of germanium target was used to cover the intrinsic a-Si: H layer by Ge NPs under a low pressure of the silane. The RLA was performed using focused excimer ArF laser beam under SiH4 background atmosphere. Reaction between ablated Ge NPs and SiH4 led to formation of Ge NPs covered by thin GeSi: H layer. The deposited NPs were covered and stabilized by a-Si: H layer by PECVD. Those two deposition processes were alternated repeatedly. Volt-ampere characteristics of final diode structures were measured in dark and under illumination as well as their electroluminescence spectra. Klíčová slova: PECVD; a-Si: H; PIN diode; Ge; nanoparticles Plné texty jsou dostupné na jednotlivých ústavech Akademie věd ČR.

Combination of cobalt bis(dicarbollide) amino derivative and antibiotic effect on growth of staphylococcus epidermidis
Lokočová, K.; Vaňková, E.; Šícha, Václav; Masák, J.
2018 - anglický
Nosocomial infections are often caused by bacteria from the Staphylococcus genus. The clinically relevant representatives of this species are Staphylococcus epidermidis and Staphylococcus aureus which grow predominantly as surface-attached stable communities known as biofilms. Cells in these biofilms are often highly resistant to antibiotics. Therefore, new antimicrobial or antibiofilm substances are still being developed. In this study, we investigated the influence of cobalt bis(dicarbollide) or its amino derivatives, and antibiotics (erythromycin, tetracycline)-alone and in combination-to determine the antimicrobial activity and the inhibition of biofilm formation against three type strains of S. epidermidis. We used a microcultivation device to determine the minimum inhibitory concentrations and MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay to determine the metabolic activity of the cells in biofilms. We observed the synergistic effect of cobalt bis(dicarbollide) and its amino derivatives with both the antibiotics on both the planktonic and biofilm cells.

The deposition of germanium nanoparticles on hydrogenated amorphous silicon.

We reveal the mechanism of Ge nanoparticles (NPs) formation on the surface of the hydrogenated amorphous silicon (a-Si:H) deposited by Plasma Enhanced Chemical Vapor Deposition (PECVD) on ITO and a on boron doped nanocrystalline diamond (BDD). The coating of Ge NPs on a-Si:H was performed by molecular beam epitaxy (MBE) at temperatures up to 450 degrees C. The Ge NPs were characterized by Raman spectroscopy, scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM). The nanocrystalline Ge particles are conglomerates of nanocrystals of size 10-15 nm and quantum dots (QDs) with size below 2 nm embedded in amorphous Ge phase. After coating with Ge NPs the a-Si:H thin films show better adhesion on BDD substrates then on ITO substrates.

The origin issue of the head of John the Baptist from Tajov
Hradilová, J.; Bezúchová, E.; Hradil, David; Šídová, K.
2017 - anglický
The significant work of art, the Head of John the Baptist from Tajov, from the Museum of Central Slovakia in Banska Bystrica, which is probably part of the works of Niclaus Gerhaert von Leiden (1420/30 - 1475), was subject to conservation as well as detailed material analysis - first using non-invasive methods (radiography computer tomography, X-ray fluorescence), then laboratory analysis of taken samples (elemental and phase analysis, analysis of organic binders, dendrochronology, radiocarbon dating). The specific painting technique was described. Gilding of the head was performed without any ground only on brown preparatory layer for oil gilding (mixtion), however, the incarnates with an oily binder did contain a light dolomitic ground layer. The blood drops painting employed madder lake including sheep wool shearlings. The work consists of two parts - the head and the bowl, which was understood not to be original. Both parts are made from poplar wood. The results of the dating indicate that the head was created in the second half of the 15th century. The bowl could have been added later, but no later than the beginning of the 16th century. Its inclusion may have happened (albeit it is less probable) in the 17th century, but any period of time after that can be ruled out. The original colouring of the bowl was different the earth pigments of specific composition used in the ground layer imitated terracotta - a clay bowl. Based on the location of the existing hanging points the head was probably on display occasionally in a vertical position with a slight bottom view of 45 degrees.

Rebecca and Eliezer at the well a mysterious oil painting from the Historical Museum of the Slovak National Museum at the Bratislava Castle
Hradilová, J.; Kližanová, H.; Bezák, M.; Holcová, K.; Bezdička, Petr
2017 - anglický
Light microscopy, scanning electron microscopy and microanalysis, X-ray powder micro-diffraction, infrared micro-spectrometry as well as palaeontological analysis have been applied in order to solve the question of provenance of the oil-on-canvas painting Rebecca and Eliezer at the well. In addition to the finding of pigments important for the dating of the painting, as, e.g. Naples yellow (Pb2Sb2O7), or smalt, fossil nannoplankton was described in the carbonate-rich clay ground. It indicates the use of marine sediments of Eocene to Oligocene age. According to mineralogical and paleontological data this ground may be included among grounds used in Italy, particularly in the 17th century. The studied painting is today greatly altered due to extensive reworkings. Prussian blue was used to overpaint faded ultramarine and degraded smalt, which is visibly affected by saponification processes. Klíčová slova: Carlo Maratta/Maratti; materials research; painting technique; micropaleontology; clay-based grounds; saponification Plné texty jsou dostupné na jednotlivých ústavech Akademie věd ČR.
