Opis:: The paper presents our recent investigations of the early stage growth of titanium silicides on a modified Si(100) substrate. The substrate was modified by deposition of a minute amount of Ni atoms, and the subsequent flash annealing. This process led to the creation of parallel defect lines on the Si(100) surface. We expected TiSi_2 to form elongated structures on top and/or between the defect lines. Though this idea failed, stable nanostructures were observed and characterized using scanning probe microscopy (scanning tunneling microscopy and atomic force microscopy) methods.

Opis:: PbSnS thin films were prepared by hot-wall vacuum evaporation. The Rutherford backscattering technique was employed for the investigation of $Pb_{x}Sn_{1 - x}S$ thin films composition. With a help of atomic force microscopy the main stages in the development of the thin films were characterized. Contact angle measurements of water drop on $Pb_{x}Sn_{1 - x}S$ thin films have been conducted on our original setup.

Opis:: In that report we observe the initial stages in the process of film growth at different irradiation doses. Investigations of influence of Mo deposition on glass substrates by means of self-ion-assisted deposition on its topography (atomic force microscopy) and wettability (sessile-drop method) were carried out. It was found out that with an increase of the irradiation dose, the average roughness and the contact angle increases rapidly at first and then decrease. 2.45-2.77 increase in the contact angle of water when Mo-based coating was deposited on the glass was observed.

Opis:: Fe-Al single crystals of three different compositions (20, 28 and 40 at.% Al) in single slip orientation were studied. Evolution of their surfaces during deformation at room temperature was observed in situ in atomic force microscope. Atomic force microscopy allows us to investigate slip lines on much finer scale than traditional optical observations. Wavy slip bands in $Fe-Al_{20},$ cross-slip in $Fe-Al_{28}$ and weak slip line texture in $Fe-Al_{40}$ are described. Post mortem observations of surfaces of $Fe-Al_{28}$ deformed at elevated temperatures (in the range of yield stress anomaly) are presented as well.

Opis:: Thin obalt films, 40 nm and 100 nm in thickness, were evaporated at an incidence angle of 45° in a vacuum of about $10^{-5}$ mbar, simultaneously on unheated glass substrates and NaCl crystals. The magnetic microstructure of these films was investigated in a previous paper. In the present paper, to obtain an insight into relation between the magnetic microstructure and the morphological structure, we studied the latter structure with atomic force microscopy and transmission electron microscopy. For the films 40 nm as well as 100 nm thick, the presence of contribution of the shape anisotropy (related to the geometric alignment of the grains of the film) to the magnetic anisotropy of the film was found. Nevertheless, for the films investigated, we could not detect crystallographic texture.

Opis:: This paper presents a comparative study between the microstructural features of two water-ferrofluids intended for biological applications. In both cases the ferrophase was prepared by auto-catalytic reaction between ferrous and ferric salts and resulted in magnetite and some maghemite precipitates. The difference is given by the stabilizer molecule: tetramethylammonium hydroxide and, respectively, citric acid. Transmission electron microscopy and atomic force microscopy were utilized for ferrophase size investigation. The evidence of short chains and large aggregates was obtained mainly by atomic force microscopy analysis (the tip diameter being equal to 5 nm). Their role in the ferrofluid rheological properties was studied by carrying out comparative measurements of viscosity and surface tension. Complementary investigation of the ferrofluid composition was done by means of IR absorption spectra. The suitability of the prepared ferrofluids for biological goals was proved by their convenient ferrophase diameter as well as by their stability in time.

Opis:: The X-ray diffraction and atomic force microscopy are used to examine the microstructure of La$\text{}_{1.85}$Sr$\text{}_{0.15}$CuO$\text{}_{4}$ films grown by pulsed laser deposition on LaSrAlO$\text{}_{4}$ substrates. The films grow with different degrees of built-in strain, ranging from a large compressive to a large tensile in-plain strain. The tensile strain cannot be attributed to a substrate-related strain. The possible origins of the tensile strain are discussed.

Opis:: The structure of the surface and spectra of the cathodoluminescence of Y₂O₃:Eu thin films when changing the activator concentration in the range 1.0-7.5% by mole obtained by RF sputtering were investigated. On the base of the shape of the cathodoluminescence spectra at different concentrations of the activator, the possibility of irregular solutions creating of yttrium and europium oxides and the structural features of the small and large crystallites forming the film Y₂O₃:Eu is shown. The dependence of the cathodoluminescence intensity on the energy of the exited electrons and current density of electron irradiation was established.

Opis:: Cubic molybdenum (Mo) nanocubes were deposited on a silicon substrate via dc sputtering. This method has been widely used to prepare the thin films containing the crystalline nanostructures. We used this approach to deposition and after that, the characterization of Mo nanocubes. Formation of these cubes was investigated by atomic force microscopy, X-ray diffractometry and four point probes, respectively. First, the mean sizes of the molybdenum cubic nanoparticles were studied under different Mo film thicknesses of 50, 80, 110, and 140 nm. Structural characterizations indicate that the as-deposited Mo nanocubes have different side-length and their distribution over the surface has been measured, separately. In the next step, according to the X-ray diffractometry, Mo crystallites were all along the (110) crystal planes of cubic structure. Finally, electrical characterizations reported that at a deposition power of 54 W, our samples exhibit an electrical resistivity, in the range of 0.92×10¯⁴ Ω cm to 0.58×10¯⁴ Ω cm.
