Ceramic materials based on lanthanum zirconate for the bone augmentation purposes: cytocompatibility in a cell culture model

Creation of new ceramic materials for the bone augmentation purposes that combine the absence of cytotoxicity, high strength and osseointegration characteristics is an urgent modern task. In this work, the cytocompatibility of ceramic materials based on lanthanum zirconate (La2Zr2O7) was determined to assess the prospects for their use as implants and components of human joint endoprostheses. The effect of ceramic materials based on undoped and alkali-earth (Ca, Sr) doped La2Zr2O7 on the viability and proliferative activity of human cells was evaluated. The release of elements into the culture medium was also evaluated

Kinetics and thermodynamics of carbon segregation and graphene growth on Ru(0001)

We measure the concentration of carbon adatoms on the Ru(0001) surface that are in equilibrium with C atoms in the crystal's bulk by monitoring the electron reflectivity of the surface while imaging. During cooling from high temperature, C atoms segregate to the Ru surface, causing graphene islands to nucleate. Using low-energy electron microscopy (LEEM), we measure the growth rate of individual graphene islands and, simultaneously, the local concentration of C adatoms on the surface. We find that graphene growth is fed by the supersaturated, two-dimensional gas of C adatoms rather than by direct exchange between the bulk C and the graphene. At long times, the rate at which C diffuses from the bulk to the surface controls the graphene growth rate. The competition among C in three states - dissolved in Ru, as an adatom, and in graphene - is quantified and discussed. The adatom segregation enthalpy determined by applying the simple Langmuir-McLean model to the temperature-dependent equilibrium concentration seriously disagrees with the value calculated from first-principles. This discrepancy suggests that the assumption in the model of non-interacting C is not valid

For this task solution it is suggested to use TrueCrypt, the crossplatform cryptographic software, allowing to carry out the on-the-fly encryption. There was conducted the analysis of TrueCrypt performance capabilities and efficiency. The algorithm of TrueCrypt practical application for storage device protection was worked out. It was shown that TrueCrypt implementation is the most effective measure which allows to prevent the losses of users' confidential information stored on PC as well as on removable storage devices

Two topics in surface science: morphological changes of NiA(111) induced by oxygen : secondary electron yield studies of Ru and TiO2 surfaces related to extreme ultraviolet lithography

This dissertation reports on two surface science projects: (1) one focuses on a study of oxygen-induced faceting of a NiAl(111) single crystal surface as a potential support for model catalysts; and (2) the other concerns secondary electron yield studies of TiO2(011) and Ru(0001), which are models of ruthenium and titanium dioxide capping layers on Mo/Si multilayer mirrors designed for applications in Extreme Ultraviolet Lithography (EUVL). It is known that monolayer films of oxygen can induce faceting of some atomically rough but planar metal surfaces. We extend our knowledge from surfaces of elemental metals to atomically rough metal alloy surfaces, such as NiAl(111). We discovered that the NiAl(111) surface exhibits an unusual behavior upon interaction with oxygen, including nanometer scale facet formation and growth of micrometer scale dendritic features. A series of experiments aimed at understanding the adsorption of oxygen and oxygen-induced faceting of NiAl(111) employing a variety of ultrahigh vacuum surface characterization methods. The atomically rough NiAl(111) surface remains planar at room temperature when exposed to oxygen. However, the oxygen-covered surface changes its morphology and forms nanometer scale facets upon annealing in the temperature range of ~1050 K to 1200K. Covered with one monolayer-thick γ-Al2O3 film, three-sided facets of {110} orientation appear. These facets coexist with the planar (111) surface. The surface becomes planar upon annealing in UHV above ~1250K. After prolonged exposure to oxygen at elevated temperatures three dimensional features exhibiting three-fold symmetry erupted from the surface; their dimensions are several micrometers in length, and ~300 nm high; their orientation is along low index directions in the plane of the NiAl(111) substrate. SEM X-ray mapping and EDS measurements indicate that these are spinel (NiAl2O4) structures; further investigation with SPEM revealed that these structures consist of γ-Al2O3 and NiAl2O4 oxides. Finally, TEM studies of the cross section of dendrites-covered NiAl(111) surface detected that γ-Al2O3 [13 ] is aligned with the NiAl[111] direction with a mismatch angle of 6˚. Ruthenium and titanium dioxide capping layers ~2 nm thick protect and extend the lifetimes of Mo/Si multilayer mirrors (MLMs) used in EUVL. The magnitude of secondary electron yield (SEY) at EUV wavelengths (13.5nm) is a major factor in determining contamination rates of MLMs in EUV projection optics. Low energy secondary electrons (0 to ~ 20 eV) cause dissociation of adsorbed hydrocarbons from the background gas, and lead to carbon film growth on MLM surfaces. In this dissertation, we investigate SEY for model EUV optics cap layer materials -TiO2 and Ru single crystals (clean, O-covered, C-covered, air exposed) and compare them with measurements for Mo/Si multilayer films capped with Ru, TiO2, and RuO2. SEY measurements were performed using synchrotron radiation over the range 40 eV to 180 eV at three different beamlines (U4A, U5UA, and U3C) at NSLS. For photon beams incident at 45˚, the shapes of the curves for Ru MLMs, especially the maxima at ~ 65 eV due to the Ru 4p excitation, are very similar to the data for pure Ru; such similarities are found also for a TiO2 crystal and TiO2-capped MLMs. The observation that the cap layer properties dominate the SEY characteristics agrees with theory. For near normal incidence, and for photon energies ~92 eV, dramatic energy- and angle-dependent resonances in SEY are observed for the capped MLMs, with SEYs 2 to 3 times higher than off-resonance. Calculations show excellent correlations between the photon electric field strength on the surface of a cap layer and the angular-dependent SEYs.Ph.D.Includes abstractVitaIncludes bibliographical referencesby Elena Loginov

Meaning construal through multimodal clusters in the theatrical discourse

The paper presents the results of an empirical study of monomodal and multimodal data collected from the plays by Russian playwrights of the second half of the 20th century (A. Vampilov, A. Kazantsev, N. Sadur) and the theatrical performances based on these plays. The main aim is to find out what semiotic modalities are more frequently involved in the process of recurrent semiosis and, as such, in the multimodal meaning construal. Following the classical as well as contemporary works in the field explored, the research sets out to elaborate the cognitive-semiotic approach to the analysis of the theatre-specific means of multimodal meaning construal to get insights into dynamicity, embodiment and figurativity of artistic expression typical of theatrical performativity and inaccessible to other arts. The data are explored by means of a complex methodology that comprises quantitative and qualitative methods with the diagraph analysis as a key analytical tool which serves to recognize meaningful correlations within and across modalities resulting from mappings between dialogically juxtaposed independent utterances. This paper demonstrates that the involvement of nonverbal resources is mainly manifested in the use of hand and head gestures, facial movements and body repositioning. Next to the quantitative results, the research shows that co-occurring conceptualizations through verbal and nonverbal components, gestures in particular, can trigger off the amplification of meaning or bring about the emergence of new conceptual projections

Graphene Growth by Metal Etching on Ru (0001)

Low-energy electron microscopy (LEEM) reveals a new mode of graphene growth on Ru(0001) in which Ru atoms from a step edge are injected under a growing graphene sheet. The injected atoms can form under-graphene islands, or incorporate into the topmost Ru layer, thereby increasing its density and forming dislocation networks. Density functional calculations imply that Ru islands nucleated between the graphene layer and the substrate are energetically stable; scanning tunneling microscopy (STM) reveals that dislocation networks exist near step edges
