   Перевод заглавия: Двухмодовой расщепленный микрополосковый резонатор и его применения в частотно-селективных устройствах
Аннотация: A dual-mode microstrip resonator whose strip conductor is partially split from its one end by a longitudinal slot has been studied. The resonator has two fundamental modes, even and odd ones. The difference of their frequencies is controlled by varying the slot length. Based on such resonators, original structures of a diplexer and passband filters including dual-band have been designed. Measured performances of their fabricated prototypes prove applicability of designed devices in microwave engineering.

bandpass filter -- multi-conductor strip resonator -- multilayer printed-circuit-board technology
Аннотация: A new monolithic design of a miniature bandpass filter for manufacture by means of multilayer printed-circuit-board technology has been developed. It is demonstrated using a fourth-order filter that multi-conductor strip resonators used in the design ensure both miniaturization and high selectivity of the device. The passband center frequency of the manufactured filter is f0 = 546 MHz, the fractional bandwidth is Δf/f0 = 25%, and the insertion loss is 0.8 dB. The filter has a wide high-frequency stopband, which extends up to a frequency of 10f0 at a level of –30 dB. The filter dimensions are 15.0 × 12.0 × 4.3 mm (0.027λ0 × 0.021λ0 × 0.007λ0, where λ0 is the wavelength in vacuum at frequency f0) and the mass is only 1.8 g. The performances of the filter and the accessibility of its design for surface mounting show that the device has great potential.

Аннотация: Doping or alloying in perovskites and perovskite variants provides a promising way for modulating the electronic and photoluminescence properties and the structural stability. In this work, a series of yellow-emitting Rb2−xCsxZrCl6:Te4+ solid solution phosphors were prepared by a hydrothermal method, and their broad emission is assigned to the triplet 3P1–1S0 self-trapped excitons (STEs). Upon increasing the alloying ion Cs+, the yellow emission can be greatly enhanced by a stronger Jahn–Teller distortion. Moreover, Cs2ZrCl6:Te4+ shows a high photoluminescence quantum yield (PLQY), and impressive thermal and anti-water stability. This doping–alloying strategy presents a new direction towards designing lead-free, high-performance and stable perovskite derivatives.

Аннотация: For modern microelectronics, at the present time, the technologies of consciousness smart structures play an important role, which can provide accuracy, stability and high quality of the structures. Submicron lithography methods are quite expensive and have natural size limitations, not allowing the production of structures with an extremely small lateral limitation. Therefore, an intensive search was conducted for alternative methods for creating submicron resolution structures. Especially attractive one is the possibility of self-organization effects utilization, where the nanostructure of a certain size is formed under the influence of internal forces. The dip pen nanolithography method based on a scanning probe microscope uses a directwrite technology and allows one to carry out a playback of small size structures with high accuracy. In the experiment, a substrate coated with Au (15 nm) using a DPN technique is applied to the polymer to form a desired pattern nano-sized channel. The experiment was conducted using a pointed probe SiN, coated MHA-Acetonitrile, on the Si(111)/Fe3Si/Au structure.

Аннотация: This paper reports studies of thin films of nickel oxide obtained by the extraction–pyrolysis method on glass and quartz substrates at temperatures of 380–600°C. The films have been characterized by atomic force microscopy and X-ray diffraction. It is shown that amorphous and crystalline nickel oxide films are formed on the glass. The grain size depends on the annealing temperature, while increased annealing temperatures lead to recrystallization and a decrease in the grain size in NiO films from 130 to 35 nm.

Аннотация: An electrodynamic analysis of an optical resonator comprising a half-wavelength dielectric layer that is covered from both sides by quarter-wavelength layers with higher and lower refractive indices (RIs) is carried out.For such a resonator, the dependences of the external quality factor on number and RIs of the layers are obtained first. That allows one to determine minimum number of the layers in the structure to achieve the required quality factor at practically any contrast of the RIs. The results of this study provide an easy way to optimize the structures of 1D photonic crystal devices, particularly high-selectivity bandpass filters.

    Automated measuring system for studying ferromagnetic resonance spectra in the radio frequency range / A. V. Burmitskikh, B. A. Belyaev, N. M. Boev, S. A.

   Перевод заглавия: Автоматизированная измерительная система для исследования спектров ферромагнитного резонанса в радиочастотном диапазоне
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.

Bandpass filter with an ultra wide stopband designed on miniaturized coaxial resonators / B. A. Belyaev [et al.] // J. Commun. Technol. Electron. - 2013. - Vol. 58, No. 2. - P. 110-117DOI 10.1134/S1064226913020022
Аннотация: Characteristics of a new miniaturized coaxial resonator are theoretically investigated. It is shown that the first resonant frequency of the resonator can be significantly lowered relative to the second one and the resonator dimensions can be considerably decreased as compared to those of a traditional dielectric filled quarter wavelength coaxial resonator. Based on the investigated resonator, a fourth order bandpass filter has been designed and fabricated. The filter stopband at a level of no worse than –90 dB extends to the frequency that exceeds the passband center frequency by a factor of 47. Calculated frequency responses are in good agreement with those measured on the fabricated filter prototypes.

polyhydroxyalkanoates -- 3-hydroxy-4-methylvalerate -- synthesis -- physicochemical properties
Аннотация: BACKGROUND: Polyhydroxyalkanoates (PHA) containing 3-hydroxy-4-methylvalerate (3H4MV) have better processing properties than other PHA types and were not prone to ageing. The main challenge in the production of these polymers is to simultaneously achieve high cell biomass, high polymer content, and high molar fraction of 3H4MV. The aim of this study was to investigate the production of poly(3-hydroxybutyrate-co-3-hydroxyvalerate-co-3-hydroxy-4-methylvalerate) [P(3HB-co-3 HV-co-3H4MV)] by Cupriavidus eutrophus B-10646, synthesize polymers with different contents of 3H4MV and investigate their properties. RESULTS: It was shown that 4-methylvalerate (4MV, the precursor substrate) concentration in the culture medium must not be higher than 1 g L−1, and that 4MV must be carefully dosed, with at least 10–12 h intervals between supplementations. A series of polymers with molar fractions of 3H4MV between 2.7 and 11.3 mol% was synthesized. Degrees of crystallinity, molecular weight characteristics, and thermal properties of the polymers have been investigated as dependent on proportions of monomers. CONCLUSION: The content of 3H4MV depends on the concentration of 4MV and conditions of carbon nutrition. The molar fraction of 3H4MV had a strong effect on the crystalline to amorphous region ratio. PHA containing 3H4MV specimens synthesized in this study had a degree of crystallinity of below 50%, which remained unchanged for 2.5 years.

Microwave remote sensing -- ultra-wide band remote sensing -- unmanned aerial vehicle -- log-periodic dipole antenna -- reflection coefficient
Аннотация: In this work, the possibility of the remote measurement of reflection coefficient in the ultra-wide frequency range from 425 MHz to 1010 MHz from the board of unmanned aerial vehicle (UAV) using ultra-wide band (UWB) radar was investigated. With this in mind, the antenna-feeder path of UAV UWB radar is calibrated. The calibration process consisted in measuring the reflection coefficient from the brass mesh sheet at various UAV hovering heights. Printed log-periodic dipole antenna was used as transmitter-receiver antenna. As a result, the antenna return loss in an empty-room and the complex antenna response function of the antenna-feeder path of the UAV UWB radar were found. It is shown that the amplitude of the reflected wave from a brass mesh sheet can be measured with root-mean square error (RMSE), RMSE=0.017 1/m and a determination coefficient (R 2 ) of R 2 = 0.967. Therewith the UAV hovering heights measured by the pulse method and the on-board laser rangefinder correlates with each other with R2=0.999 and with RMSE=3.5cm (distance measurement error of the laser rangefinder is ±1cm, surface irregularities of the brass mesh sheet were no more than 1.5cm). Measured in the frequency range from 500 MHz to 900 MHz, the reflection coefficient from fresh lake water by UAV UWB radar with a relative error of no more than 7.5% (practically does not depend on the height of the UAV hovering, approximately from 2.2 m to 5.2 m) coincides with the calculated one by the Stogryn's formulas.

core-shell Fe3O4@C nanoparticles -- core-shell Fe3O4@C@C nanoparticles -- magnetic properties -- dyes adsorption
Аннотация: This work is devoted to the study of magnetic Fe3O4 nanoparticles doubly coated with carbon. First, Fe3O4@C nanoparticles were synthesized by thermal decomposition. Then these synthesized nanoparticles, 20–30 nm in size were processed in a solution of glucose at 200 °C during 12 h, which led to an unexpected phenomenon – the nanoparticles self-assembled into large conglomerates of a regular shape of about 300 nm in size. The morphology and features of the magnetic properties of the obtained hybrid nanoparticles were characterized by transmission electron microscopy, differential thermo-gravimetric analysis, vibrating sample magnetometer, magnetic circular dichroism and Mössbauer spectroscopy. It was shown that the magnetic core of Fe3O4@C nanoparticles was nano-crystalline, corresponding to the Fe3O4 phase. The Fe3O4@C@C nanoparticles presumably contain Fe3O4 phase (80%) with admixture of maghemite (20%), the thickness of the carbon shell in the first case was of about 2–4 nm. The formation of very large nanoparticle conglomerates with a linear size up to 300 nm and of the same regular shape is a remarkable peculiarity of the Fe3O4@C@C nanoparticles. Adsorption of organic dyes from water by the studied nanoparticles was also studied. The best candidates for the removal of dyes were Fe3O4@C@C nanoparticles. The kinetic data showed that the adsorption processes were associated with the pseudo-second order mechanism for cationic dye methylene blue (MB) and anionic dye Congo red (CR). The equilibrium data were more consistent with the Langmuir isotherm and were perfectly described by the Langmuir–Freundlich model.

Autotrophic synthesis -- Cupriavidus eutrophus -- Polyhydroxyalkanoates
Аннотация: Synthesis of polyhydroxyalkanoates (PHAs) by a new strain of Cupriavidus - Cupriavidus eutrophus B-10646 - was investigated under autotrophic growth conditions. Under chemostat, at the specific flow rate D=0.1h-1, on sole carbon substrate (CO2), with nitrogen, sulfur, phosphorus, potassium, and manganese used as growth limiting elements, the highest poly(3-hydroxybutyrate) [P(3HB)] yields were obtained under nitrogen deficiency. In batch autotrophic culture, in the fermenter with oxygen mass transfer coefficient 0.460h-1, P(3HB) yields reached 85% of dry cell weight (DCW) and DCW reached 50g/l. Concentrations of supplementary PHA precursor substrates (valerate, hexanoate, ?-butyrolactone) and culture conditions were varied to produce, for the first time under autotrophic growth conditions, PHA ter- and tetra-polymers with widely varying major fractions of 3-hydroxybutyrate, 4-hydroxybutyrate, 3-hydroxyvalerate, and 3-hydroxyhexanoate monomer units. Investigation of the high-purity PHA specimens showed significant differences in their physicochemical and physicomechanical properties. В© 2013 Elsevier Ltd.
