Atherosclerosis -- Monocyte-macrophages morphology -- Alkanoate-based bionanofilms -- Surface relief
Аннотация: The effect of surface relief profiles of alkanoate-based bionanofilms to the monocyte-macrophages (MN-MPhs) from peripheral blood of patients with atherosclerosis was studied in vitro. Patients were subjected to coronary stenting. Cell morphology and phenotype (expression of CD antigens, levels of production of marker cytokines) in vitro were analyzed before and after the installation of stents. It was shown, that the mean square roughness (Rq) of the bionanofilms determined the variability of cell morphology, CD antigens spectraand activity of production interleukins-6 and-10. Also, it was revealed, that the “activity” of the surface topography of biopolymer substrates depends on the functional state of MNs, isolated in different time points: Before and after stenting the ratios of cell morphotypes and production of cytokines in MN-MPhs differed significantly.

Ferrihydrite nanoparticles -- Morphology -- Laurdan -- TMA-DPH -- Membrane -- Fluidity
Аннотация: In recent years was observed an increased interest towards the use of metal nanoparticles for various biomedical applications, such as therapeutics, delivery systems or imaging. As biological membranes are the first structures with which the nanoparticles interact, it is necessary to understand better the mechanisms governing these interactions. In the present paper we aim to characterize the effect of three different ferrihydrite nanoparticles (simple or doped with cooper or cobalt) on the fluidity of model lipid membranes. First we evaluated the physicochemical properties of the nanoparticles: size and composition. Secondly, their effect on lipid membranes was also evaluated using Laurdan, TMA-DPH and DPH fluorescence. Our results can help better understand the mechanisms involved in nanoparticles and membrane interactions.

Gold -- Morphology -- Nanocrystals -- Silicides
Аннотация: The growth of α-FeSi2 nanocrystal ensembles on gold-activated and gold-free Si(001) surfaces at different Si/Fe flux ratios via molecular beam epitaxy is reported. The study reveals that the utilisation of gold as a catalyst regulates the preferable orientation relationship (OR) of the nanocrystals to silicon and their morphology at a given Si/Fe flux ratio. α-FeSi2 free-standing crystals with continuously tuned sizes from 30 nm up to several micrometres can be grown with an α(001)//Si(001) basic OR under gold-assisted conditions and an α(111)//Si(001) OR under gold-free growth conditions on a Si(001) surface. The preferred morphology of nanocrystals with a particular OR can be altered through changes to the Si/Fe flux ratio. Herein, the microstructure and basic OR between the silicide nanocrystals and the silicon substrate, and the formation of nanocrystal facets were analysed in detail with the help of microscopic techniques and simulation methods based on the analysis of near coincidence site (NCS) distributions at silicide/silicon interfaces. On the basis of the simulations used, we managed to reveal the nature of the interfaces observed for the main types of α-FeSi2 nanocrystals grown. Three types of interfaces typical for nanoplates with an α(001)//Si(001) basic OR, which are (i) stepped, (ii) stressed, and (iii) flat, are explained based on the tendency for the NCS density to increase at the interface. The results presented reveal the potential for the bottom-up fabrication of α-FeSi2 nanocrystals with tuned physical properties as potentially important contact materials and as building blocks for future nanoelectronic devices.

Lead-free ceramics -- Raman spectroscopy -- Domain morphology -- Photoluminescence
Аннотация: Present work focuses on detailed temperature-dependent X-ray diffraction, Raman scattering, domain configuration, and photoluminescence (PL) studies in the (Ba0·85Ca0.15) (Zr0·10Ti0.90)O3 (BCZT) ceramics. The comprehensive Raman spectroscopy analysis in the present work not only validates the presence of the intermediate orthorhombic phase in BCZT, but also provides evidence of another transition: rhombohedral R3c phase to R3m at low temperature. Temperature behaviour of the lowest frequency transverse optical mode (soft E (TO) phonon) and hard modes was studied. Temperature dependence of peak positions, intensities, and linewidths of Raman phonon modes signalled the presence of phase transitions near −50 ± 5 °C, 0±5 °C, 35±5 °C and 110 ± 10 °C. Evolution of domain morphology occurring at phase transitions above room temperature was studied by piezoresponse force microscopy technique. Analysis of PL spectra revealed disorder/heterogeneity in the sample and indicated the existence of self-trapped excitons. PL spectra are composed of four distinct colour components (~2.55eV:blue, ~2.32eV:green, ~2.08eV:orange and ~1.78eV:red).

Аннотация: The saturation magnetizations, local magnetic anisotropy field and coercivity values of FeCo film plated under various processing conditions have been investigated to optimize soft magnetic properties. Herein, we introduce a very promising processing technique based on the electrodeless deposition of FeCo film with carbohydrates as reducing agents. The produced FeCo film demonstrated significantly better saturation magnetization values and less contaminations, compared to those for the sample preparing with conventional reducing agent (sodium hypophosphite). The surface morphology and coercivities of FeCo films are dependent on the iron content and type of reducing agent. The coercive force values range from 12 up to 30 Oe and the saturation magnetization from 150 to 240 emu/g depending on the bath composition and deposition parameters. Maximum of saturation magnetization magnitude is reached for FeCo film with 30% cobalt. The local anisotropy field value of FeCo alloys increases with a decrease in Fe content for all reducing agent types.

Effect of molecular weight of sodium polyacrylates on the size and morphology of nickel nanoparticles synthesized by the modified polyol method and their magnetic properties / O. A.

Кл.слова (ненормированные):
Nickel nanoparticles -- Sodium polyacrylate -- Polyol -- Reduction -- Magnetic properties
Аннотация: Nickel nanoparticles were synthesized by the reduction of nickel chloride with hydrazine hydrate in a polyol medium in the presence of sodium polyacrylates (Na-PA) having molecular weights (Mw) of 1200, 5100 and 8000. The size and morphology of the resulting nickel nanoparticles were characterized by X-ray diffraction, scanning and transmission electron microscopy. Polymers having lower Mw values were found to be more efficient in reducing the nickel particle size. A decrease in the polymer concentrations yielded the smaller particles. Magnetic measurements showed that the as-prepared powders are ferromagnetic and their saturation magnetization and coercivity are size-dependent. Compared with bulk nickel, the nanoparticles exhibit an enhanced coercivity which is due to their small size and a decreased saturation magnetization resulted from the surface oxidation of the powder. The synthesis procedure offers a simple approach to preparing nickel nanopowders on a large scale which could be used as magnetic recording materials, including high-density memory storage devices.

Аннотация: A cold finger cell intended for the wax deposition measurements was fabricated and integrated into an NMR imaging probe for the noninvasive study of wax precipitation processes in situ. The cell was first tested with a model system; then, a series of experiments with different thermal gradients applied to the cell were performed for a waxy crude oil. NMR imaging of the operating cell revealed the formation of a deposit with the morphology and dynamics strongly correlating with the temperature regime. At higher temperatures of cold finger, the incipient wax gel ages uniformly, giving rise to the hard and thin inner layer of deposit accompanied by a branched loosely consolidated outer layer. Conversely, the lower temperatures facilitate formation of a thick deposit which no longer ages uniformly and slow down the diffusion-controlled growth of the branched deposit structure. The results obtained are consistent with the majority of the data previously reported. Thus, gelation of the wax at temperatures below the cloud point and subsequent thermal-driven diffusion processes are considered to be the dominant mechanisms of the deposit formation. The counter diffusion and Ostwald ripening aging concepts were found to be relevant in the case of the cold finger study and account for the phenomena observed in this work. The information obtained via NMR imaging is highly complementary to the results obtained by other techniques that can aid in understanding the essential processes behind the wax precipitation phenomena. The approach developed can be effectively extended to study any thermal-driven phase separation process. © 2016 American Chemical Society.

Monocytes -- Macrophages -- Cell morphology -- Polyhydroxyalkanoates -- Atherosclerosis -- Intravascular stenting
Аннотация: The morphotypes of human macrophages (MPh) were studied in the culture on nano-structured biopolymer substrates, made from polyhydroxyalcanoates (PHAs) of five various monomer compositions, followed by the solvent evaporation. Its surface relief, which was further in direct contact with human cells in vitro, was analyzed by atomic force microscopy (AFM) and scanning electron microscopy (SEM). It was shown, that the features of the micro/nano relief depend on the monomeric composition of the polymer substrates. Monocytes (MN) of patients with atherosclerosis and cardiac ischemia, undergoing stenting and conventional anti-atherosclerotic therapy, were harvested prior and after stenting. MN were isolated and cultured, with the transformation into MPh in direct contact with biopolymer culture substrates with different monomer composition and nano-reliefs, and transformed into MPh, in comparison with the same process on standard culture plastic. Sub-populations of cells with characteristic morphology in each phenotypic class were described, and their quantitative ratios for each sample of polymers were counted as an intermediate result in the development of “smart” material for cardiovascular devices. The results obtained allow us to assume, that the processes of MPh differentiation and polarization in vitro depend not only on the features of the micro/nano relief of biopolymer substrates, but also on the initial state of MN in vivo and general response of patients.

Аннотация: The aim of this study is to develop a manufacturing technique of polymethylmethacrylate (PMMA) nanospheres to produce a more stable opal template. Water-acetone mixture was used as a dispersion medium to synthesize a PMMA opal structure. Morphology features, IR vibrational spectra and glass transition temperatures of the PMMA nanospheres formed in the water-acetone dispersion medium (nanospheres A) have been studied comparing with the same prepared in distilled water solution without acetone (nanospheres B). A dependence of a shrinkage degree of the nanoparticles on the acetone volume has been investigated. It has been revealed that under an electron beam action the shrinkage degree of the nanospheres A is in the range of 7-16% while the shrinkage of the nanospheres B is 18-25% at the same conditions. The nanospheres A are less flexible and soft as compared to the nanospheres B. Additionally, an ability of the PMMA nanoparticles fabricated in the water-acetone dispersion medium to form the ordered opal structures is demonstrated to be the similar to the nanospheres B.

Показано, что напряжение анодирования оказывает существенное влияние на структуру нанопленок и, соответственно, на их фотоэлектрокаталитическую активность. Методом катодного осаждения Cu2O на анодированный TiO2 получен фотоанод с гетеропереходом. Установлено, что фотоэлектроактивность такого анода при потенциале 1В (отн. Ag/AgCl/3,5MKCl) на 15% выше, чем активность исходной наноструктурированной TiO2 пленки.
Nanostructured titanium dioxide films were prepared by electrochemical oxidation technique, anodization voltage effect on structure morphology, optical and photoelectrocatalytic performances of the nanotubes were studied. The anodization voltage is shown to significantly affect structure of nanofilms and, accordingly, their photoelectrocatalytic activity. An active heterojunction photoanode was synthesised with electrode position of Cu2O onanodized TiO2. The anode photoelectroact ivity under bias 1V (Ag/AgCl/3,5M KCl) is found to be 15 % higher than that of the original nanostructured TiO2 film.

Hematite -- α-Fe2−xCrxO3 -- Morin transition -- Nanorods -- Magnetization -- Magnetic circular dichroism
Аннотация: Hematite, α-Fe2O3, one of the most widely studied magnetic compounds known to mankind since ancient times, has amazing properties and continues to puzzle researchers to this day. In this work, we found exceptionally strong changes in the morphology and magnetic properties of hematite nanoparticles upon doping with rather low concentrations of chromium. Nanoparticles α-Fe2−xCrxO3 with x varied from zero to 0.15 were prepared by solvothermal method using FeCl3·6H2O, CrCl3·6H2O, and 1,2-diaminopropane, (CH2)3(NH2)2, as precursors and temperature 180 °C for 6 h. The X-ray diffraction data showed the presence of only one crystal phase α-Fe2O3 for all x meanings with growing average crystalline size as the x increases. For the parent α-Fe2O3 powdered samples, the transmission electron microscopy revealed very long narrow nanorods with rounded ends that transform into spindles of increasing volume and cross section diameter as the Cr concentration increases. Vibrating sample magnetometry (VSM) and magnetic circular dichroism (MCD) study of the nanoparticles behavior in dependences on temperature and magnetic field revealed many unusual peculiarities. Among them there are strong increase of NPs magnetization with x increase (usually opposite picture is observed), the Morin transition temperature TM dependence on magnetic field, VSM sees the Morin transition in samples with small x only while MCD – in all samples, magnetization field dependences also are different when measured with VSM and MCD, and so on. Qualitative considerations were proposed to explain the observed phenomena.

Аннотация: A plasma-chemical method for the modification of silicon carbide particles is presented, which makes it possible to obtain particles with a controlled surface morphology. The variable parameter of particle processing was the ratio of the fraction of plasma-forming (Ar) and additional (H) gases. It was shown that at Ar/H = 100/0, the formation of a carbon shell is observed; at Ar/H ratios of 91/9 and 84/16, the particles are characterized by a carbon shell decorated with silicon nanoparticles or nanowires, respectively. The modified particles were analyzed using scanning electron microscopy and Raman spectroscopy.
