Заглавие : Atomic layer deposition ZnO on porous Al2O3 nanofibers film

Аннотация: The paper presents the results of the formation and study of the morphological and structural characteristics of the mesoporous ZnO / Al2O3 nanofibers film (ZANF). The deposition of a ZnO layer on Al2O3 nanofibers film (ANF) ~ 1 µm thick was carried out by the method of atomic layer deposition. The morphology of the mesoporous composite layer ZnO / Al2O3 (ZANF) has been studied by scanning and transmission electron microscopy. It is shown that in the process of atomic layer deposition, the ZnO layer grows according to the Stranski-Krastanov mechanism. A ZnO layer less than 5 nm thick gives an island structure in which Al2O3 nanofibers are uniformly coated with ZnO particles, an increase in the ZnO layer thickness to 15 nm demonstrates a continuous coating of Al2O3 nanofibers. The system has a core-shell structure. The resulting composite structures are promising for applications in photocatalysis and gas sensing.

Аннотация: The automated system for measuring ferromagnetic resonance spectra in the radio frequency range has been developed for measuring magnetic characteristics of thin films. The system allows measuring the spectrum of ferromagnetic resonance at a frequency of 12 MHz with a field step of 0.01 Oe (constant or variable) and with 0.0125° angle resolution. Automatic determination of the anisotropy field and automatic sensitivity adjustment of the measuring system allows obtaining data from permalloy thin magnetic films samples with thickness less than 50 nm. Measurements can be carried out with different directions of external magnetic fields (in the plane of the TMF sample) and with rotation of the sample in the external magnetic field. This is achieved by the independent automatic rotation of the sample and high-frequency Helmholtz coils. Processing and transmission of the received data in the digital form provides automatic processing and representation of measurement results on the PC screen. The measurement results can be used for TMF study, assessing the quality, rejection and further use in finished devices.

Аннотация: In this paper demountable K/Q bands feed for satellite communication Cassegrain antenna is reported. The feed is based on the combined coaxial-circular waveguide, in which outer wall of a circular waveguide is used as an inner conductor of a coaxial waveguide. This design allows to simultaneously transmit and receive signals in two widely separated frequency bands. A coaxial joint, which is the key part of the feed, is proposed and described in details. The joint performs several functions. First is to transmit the microwave energy through both waveguides. Second is ensuring the waveguides sealing. And third is ensuring the circular and coaxial waveguides alignment. The joint simulation results demonstrated return loss below-20 dB and insertion loss less than 0.06 dB in 20-21 GHz frequency range (K-band) as well as return loss below-30 dB and insertion loss less than 0.15 dB in 43-45.5 GHz frequency range (Q-band). Mechanical prototype of the joint was manufactured and tested.

Аннотация: This paper presents analysis of optical images of films obtained by evaporation (293 K) of a thin layer of low-concentrated (1% wt.) aqueous soot suspensions in a Petri dish. Suspensions of wood, fullerene and diamond-containing (after detonation synthesis) soot were prepared using hydrodynamic dispersion in a cavitation mixer with a wedge-shaped cavitator with the rotor's angular velocity of rotation being 10000 rpm. The components of the hydrodynamic dispersion process are turbulent micro-mixing and bubble cavitation. As a result of intense turbulence, carbon suspensions assumed properties of non-equilibrium systems. The images of an optical microscope revealed self-organized dissipative micron-sized structures in the dried films being present there in the form of chain, branched and ring-shaped cluster fractals of various dimensions that look very similar to nanotubes. The self-assembling effect was identified for all the types of suspensions under study. The EPR method was used to study the change in the electronic structure of soot resulting from the exposure to high temperatures and pressures that occur when the cavitation bubbles collapse (cavitational activation). The dynamics of changes in dissipative structures in the process of film drying was monitored.

Аннотация: Coal-water slurry (CWS) is the basis of modern alternative fuel - coal-water fuel (CWF). To produce stable coal-water slurry, i.e. coagulation and separation is an important technological problem. The paper studies CWS the disperse part of which is fine brown Kansk-Achinsk coal, the dispersive part is distilled water. Effect of cavitational conditioning on CWS stability has been studied. The efficiency was for the first time studied by magnetic resonance tomography (MRT). In the experiment spin-lattice relaxation time profiles T1 were recorded along the central vertical axis of the samples. T1 dynamics correlates well with the local density of CWS solid phase. MRT data was sequentially interpreted with rheological characteristics of CWS. Feasibility of applying MRT method to find out time and space evolution of CWS has been estimated. The MRT methods has been shown to be efficient in resolution of technological problems to improve consumer properties of the coal-water fuel.

Аннотация: Confident effect of five magnetic composite nanoparticles (FeP@Ag, FeP@Pd, CoP, NiP, Fe2O3@AГ) on growth of test bacteria colonies (Acinetobacter baumannii, Еscherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus) in five replicates each is considered. Reliable inhibitors of colonies of all five test bacteria were nanoparticles FeP@Ag. CoP nanoparticles are reliable inhibitors of growth of 4 test bacteria (except for test bacteria Escherichia сoli). NiP nanoparticles are reliable inhibitors of growth of 2 test bacteria: Escherichia сoli and Klebsiella pneumoniae. Bacteria Escherichia сoli were most sensitive to the effect of magnetic nanoparticles; and bacteria Pseudomonas aeruginosa and Staphylococcus aureus were most resistant to the effect of magnetic nanoparticles. The prospects of the method are in the possibility of multiple reuse of the magnetic particles with antimicrobial properties for bacterial decontamination of the studied sources of water and removal of magnetic nanoparticles from the treated liquids by electromagnet. The method can find use in water treatment facilities for household, Industrial and medical wastes.

Заглавие : Electrooptical bistability and thermoaddressed information recording in polymer dispersed cholesterics
Коллективы : International liquid crystal workshop on surface phenomena
Место публикации : Proceedings SPIE. - 1996. - Vol. 2731. - P.162-170
Аннотация: The reflection spectra of cholesteric liquid crystals dispersed in polymer and comprising pyrimidine dopes are investigated in the entire temperature range of the mesophase existence. One or several oxyphenyl substituents in an ortho position implemented into a pyrimidine system induce the second reflection region. The reflection curves for different wavelengths corresponding to regions I and II merge with temperature. Thermodynamically equilibrium states of polymer-dispersed cholesterics under the influence of polar pyrimidine dopes are considered. The pyrimidine effect is modulated by the orientational near-surface potential. The existence of two space regions of a spherical droplet with different helix pitches is validated. The natural helix pitch is retained inside the droplet while a new pyrimidine-induced pitch is formed in a layer close to the droplet surface. The results obtained describe the existence of two reflection regions and the temperature behavior of the helix pitch.

Заглавие : Laser addressed information recording in bistable PDChLС films
Коллективы : International Liquid Crystal Conference
Место публикации : 16th International Liquid Crystal Conference (ILCC 1996): program and abstract book. - 1996. - Ст.B1P.39. - P.53
Аннотация: Polymer dispersed cholesteric liquid crystal (PDChLC) films exhibiting a large hysteresis of the volt-contrast curve were used for laser addressed information recording. Switching over ofthe bistable state was provided by a local heating of the PDChLC film due to the thermal effect of the light A proper dye was added to ChLC to increase the light absorption and thus improve sensitivity of the method. Unlike the photoaddressed method [1], here recording is possible not only in a normal mode (a transparent spot against a scattering background), but in a reverse mode too. With this method no photoconductive layer is required in the cell design. Image recording with grey levels was obtained by varying the duration or the amplitude ofthe laser pulse.

Аннотация: This paper considers resonant and non-resonant methods for measuring magnetic characteristics of Ni 80 Fe 20 thin films with 1000 Å thickness. The imaginary part of complex magnetic permeability was measured by using resonant and nonresonant measuring cells. The resonant measuring cell included: a micro-strip line, a lumped capacitance, and an amplitude detector. The non-resonant measuring cell included a short-circuited micro-strip line. The studied sample of thin magnetic film is placed under the short-circuited micro-strip line. The self-resonant frequency of the non-resonant measuring cell is higher than frequency of the ferromagnetic resonance (in field, equal 14 Oersteds). Ferromagnetic resonance method was used to study the change of measuring cell resonant frequency. The angular dependences of resonant frequency were achieved by the change of angle between constant magnetic field and high-frequency field of excitation, the hard axis of magnetization in thin magnetic film. The measurements were carried out using automation units. A numerical comparison of the obtained results showed that the difference between measurements does not exceed 5%.

Аннотация: The magnetic properties of thin magnetic films are of scientific and practical promise due to their of the physical properties. The presence of hysteresis loops is the specific characteristic feature of ferromagnetic materials. Some magnetic characteristics, as well as the quality of a thin ferromagnetic film can be determined by the hysteresis loop. The paper considers a new measuring unit for the observation of hysteresis loops in thin ferromagnetic films. A structural scheme, a sketch of the measuring unit, an external appearance are presented. Two Hall sensors were used as a sensitive element. Detailed description of the design is given and the advantages of the new unit over its analogues are shown. The results of the experiment confirm that the newly developed measuring unit can be used to solve various scientific and practical problems, e. g., for the express measurement analysis of hysteresis loops in thin magnetic film device manufacturing. The experiment was carried out on a thin ferromagnetic film of permalloy Ni 80 Fe 20 composition with 8 magnetic layers. The sample was obtained by magnetron sputtering of a permalloy target on a glass substrate in vacuum. The dimensions of the film were 4 × 8 mm. The new measuring unit allows to use any external sources of alternating magnetic field. The sensitive elements (Hall sensors) of the unit can be replaced by other magnetic field sensors.

Аннотация: The article presents the results of measuring the generation of the second harmonic in a microstrip transmission line and in a quarter-wavelength stepped-impedance microstrip resonator with a thin permalloy magnetic film (Ni80Fe20 ). The measurements were carried out for three samples with different thicknesses – 50 nm, 75 nm and 100 nm, at an input signal excitation frequency of 1 GHz and maximum input power of ~3500 mW. It was shown that the level of the second harmonic rises as the TMF thickness increases. It was found that a 100-nm sample generates the second harmonic more efficiently due to the larger ΔH FMR and the larger amount of magnetic material involved in the process of nonlinear conversion of the input power. It was shown that the resonator-based frequency doubler has a conversion factor ~4500 times higher than that of the doubler based on the microstrip line due to the higher value of the loaded Q-factor. Therefore, a quarter-wavelength stepped-impedance microstrip resonator can be used as a frequency doubler.

Аннотация: The paper is devoted to simulation, designing and fabrication of a microstrip 5-order bandstop rejecting filter. The bandstop filter uses classic schem, e.g. it consists of a microstrip through (common) line whose ends serve input and output ports. In the vicinity of the line a number of microstrip rejecting resonators locate, in our case five S-shaped resonators. They electromagnetically interact with the line, that forces signals, having frequenscies, bieng equal to the resonant ones, to reject (reflect) from a device. Dielectric substrate of the device has thickness 1.0 mm, and other sizes are 44.0×20.0 mm 2 . The filter described in this work has shielding. In a band 1480 MHz …1499 MHz rejection exceeds 50 dB. Transmission bands at a level –2 dB are 0…1437 MHz and 1563 MHz…3000 MHz lower and upper correspondingly. Return loss in the passbands does not exceed –16 dB (VSWR≤1.4). Good agreement is observed between simulated and experimental data. Fabricated filter has small size.
