Opis:: Results concerning the morphology of Cu adsorption layers deposited from vapor under ultrahigh vacuum on Ir tip and the influence of oxygen on this morphology are reported. The method employed was field electron emission microscopy. It was found that the presence of oxygen decreases the copper wettability of iridium. Preadsorption of oxygen on the Ir surface is followed by an increase in cohesion interaction between atoms of the Cu deposited onto the tip at room temperature. Coadsorption of Cu and O on the Ir tip surface at liquid nitrogen temperature, when followed by gradually heating the adlayer, results in crystallization of the deposit in the temperature range from 430 K to about 700 K. Some evidence indicates the formation of Cu$\text{}_{2}$O with a high degree of crystallinity under these conditions. Cu and O coadsorption on the Ir surface at a temperature higher than 1090 K leads to selective accumulation of Cu on the {111} faces and to formation of epitaxial crystals which are oriented to the substrate in the same manner as the Cu crystals grown at ultra-high vacuum from Cu flux containing no oxygen. Oxygen incorporated into the Cu beam interact preferentially with {011} and {001} Ir faces, where it can produce oxide layers.

Opis:: Adsorption of N, N'-dioctyl-3,4,9,10-perylenedicarboximide (PTCDI-C8) on the Si(100) surface has been examined using X-ray photoelectron spectroscopy and scanning tunneling microscopy. X-ray photoelectron spectroscopy results show that the bonds are formed between the carbonyl groups of the molecules and the substrate. Scanning tunneling microscopy results show that the first and further layers are disordered.

Opis:: Atomic force microscopy and scanning tunneling microscopy have been used for nanometer scale modifications of Sb films deposited on 6H-SiC(0001) surface. The films are grown in situ by vapor deposition under ultrahigh vacuum. The growth follows the Volmer-Weber mode. Ultrathin (up to 3 nm on average) Sb films which consist of no coalesced islands can be modified by moving the island over the substrate surface by the AFM tip. Thicker films, which are firmer due to the coalescence, can be modified by the field and/or current produced by STM tip. Final result of the modifications is adsorbate free 6H-SiC(0001) surface restitution over the modified area.

Opis:: TiO2 thin films were grown on silicon substrates using an electron-beam evaporator. Grainy TiO was used as the evaporation material. Temperature substrate during TiO2 growth was relatively low (about 150 °C), what is important for many optoelectronic devices and multilayers mirrors. High vacuum condition allows to maintain clean surfaces substrates before and during oxide growth. The morphology of titanium oxide thin films was ex situ investigated using atomic force microscopy operating in contact mode, X-ray photoelectron spectroscopy, X-ray powder diffractometry, and by means of a contact angle analyzer. The influence of annealing treatment and exposure to UV–VIS radiation on the morphology has been also discussed.

Opis:: The electronic structure of p-type GaN(0001) surfaces and its modification by antimony adsorption, and properties of Sb/GaN(0001) interface, are presented in this report. The studies were carried out in situ by ultraviolet photoelectron spectroscopy, X-ray photoelectron spectroscopy, and low-energy electron diffraction. Thin Sb layers were deposited under ultrahigh vacuum conditions onto the substrate at room temperature. Electron affinity of clean p-GaN surface amounted to 3.0 eV. A small amount of Sb on GaN(0001) surface reduced the electron affinity to 1.9 eV. The work function of the Sb layer was equal to 4.4 eV. For the Schottky barrier height of the Sb/GaN interface, the value of 2.50 eV was obtained.

Opis:: Near-field scanning optical microscopy is a technique providing images of structures with spatial resolution better than λ/2, which is undetectable in far-field where the Abbe law of limiting resolution is critical. In parallel to the optical imaging, topography maps are also acquired. Near-field scanning optical microscopy measurements can be performed both in air and liquid environments. The later makes the technique very useful for biomaterials analysis offering information that could not be obtained with other methods. Our work presents the results of recent studies on application of near-field scanning optical microscopy to imaging of cells in air as well as in physiological buffers. Differences in cell's topography and morphology have been noticed between two cell lines from human bladder non-malignant (HCV29) and malignant (T24) cancers. Presented results are part of the research that characterizes physiological changes of cells depending on stage of cancer.

Opis:: Sarmatian sands and bur ied Pleis to cene val leys of the Kedzierzyn-Głubczyce Subtrough represent one of the main aquifers in southern Poland ( MGWB-332 - Major Ground Water Basin). This aquifer is intensively exploited, supplying tap water for the human population and for industry in the whole area; but, being confined, it has no influence on the ground water ecosystems. Two Ground Water Bodies (GWB-128 and GWB-129), introduced by administrative decisions according to EUDirectives, approximately cover the area of MGWB-332. The present study is related to the eastern part, the Sarmatian and buriedval eys sands of MGWB-332, i.e. to the most im - portant part of the multiaquifer GWB-129 which in profile consists of Holocene and Pleistocene sands, confined Sarmatian and Pleistocene buried valley sands, and Badenian sands. The presence and influence of deeper permeable formations is not addressed. The Sarmatian and Badenian aquifers are recharged and drained mainly by vertical seepages. Hydrodynamic modelling of the whole Kędzierzyn-Głubczyce Subthrough and tracer data indicate modern ages at the out crops of the Sarmatian under the Pleistocene deposits and mid to early Holocene ages close to the Odra River valley. Waters are of the HCO3-Ca type, changing at the centre of the Sarmatian to the SO4-Ca type due to the contribution of ascending sulphate water from the Badenian strata, whereas water in the buried Quaternary valley is of the HCO3-Na type, which means no significant contribution of ascending waters. Polluted modern waters occur only at the north west ern boundary in the area of the hydrogeological window. The quality of waters and their hydrochemistry result from water-rock in teractions and seepage exchanges with overlying and underlying aquifers belonging to the same GWB. Natural distributions of most major, minor and trace constituents are very wide, exemplifying difficulties in defining the quality of water in aunique way for the whole aquifer and particularly for the investigated multi-aquifer GWB.
