Заглавие : Adsorption properties and catalytic activity of Fe3O4-Ag nanostructures

Аннотация: The morphology and magnetic properties as well as adsorption capacity and catalytic activity of Fe3O4-Ag nanoparticles synthesized by the solvothermal method were studied in dependence on the duration of the thermolysis process (3, 6, and 8 h). X-ray diffraction, transmission electron microscopy, and energy-dispersive spectroscopy measurements showed that the morphology of nanoparticles changed strongly as the duration of thermolysis increased. At 6 and 8 h duration, Fe3O4 nanocrystals grow and assemble into porous spherical globules with an Ag core (samples 2 and 3). These samples demonstrate high magnetization value and very low coercivity. The adsorption capacity of nanoparticles was studied with respect to two organic dyes: cationic methylene blue (MB) and anionic Congo red (CR). The particles showed preferential adsorption of the cationic dye. High catalytic activity towards four dyes: MB, methyl orange (MO), CR, and Rhodamine C (RhC) at the presence of NaBH4 is the remarkable property of these samples. The rate constant of the catalytic reaction was 1.4 min−1. Simultaneous exposure of CR and MO dyes to nanoparticles and NaBH4 caused their irreversible 100 % degradation while in the case of MB and RhC, a transition to their leuco form occurred.

Аннотация: A fullerene mixture was enriched with endohedral metallofullerenes (EMF) using Lewis acid (TiCl4), which took 22 min, whereas the standard method requires about 8 h. An algorithm for assessing small-area chromatographic peaks has been proposed, which has improved the accuracy of determination. For example, the area of the C84 peak was 4.24% using the developed program, while the use of chromatograph software estimated the area of this peak to be 1.78%.

Аннотация: Наноструктурированные фотонно-кристаллические пленки TiO2 анодно синтезированы при импульсном и ступенчатом изменениях напряжения. Полученные фотонные структуры активированы методом циклической вольтамперометрии в 0,5M Na2SO4. Фотоэлектрохимическая активность электродов исследована в реакции разложения воды в области длин волн 360–700 нм. Активация приводит к изменению энергии запрещенной зоны, красному сдвигу спектра IPCE и увеличению его значений в исследованном диапазоне длин волн.TiO2 photonic crystal nanostructure films are anodic synthesized with pulsed and stepwise voltage changes. The obtained photonic structures were activated by cyclic voltammetry in 0.5M Na2SO4. The photoelectrochemical activity of the electrodes was studied in the water splitting reaction in the wavelength range 360–700 nm. Activation leads to a change in the band gap energy, a red shift in the IPCE spectrum and an increase in its values in the studied wavelength range.

Заглавие : Polarization-sensitive resonant absorber based on splitted tamm plasmon polariton
Место публикации : Photonics Nanostruc. Fundam. Appl. - 2023. - Vol. 53, Is. 16. - Ст.101094. - ISSN 15694410 (ISSN), DOI 10.1016/j.photonics.2022.101094. - ISSN 15694429 (eISSN)
Примечания : Cited References: 55
Аннотация: The possibility of creating a polarization-sensitive absorber on the basis of the splitting of a Tamm plasmon polariton at the interface between a metallic film and an anisotropic nanocomposite layer conjugated with a photonic crystal is theoretically predicted. The effect of geometrical parameters on the optical absorption spectra under the critical coupling conditions is discussed. It is shown that, changing the polarization of the radiation falling onto the structure along its normal, one can control the absorption at the Tamm plasmon polariton wavelength.

Аннотация: (Mg/ZrO2)52 multilayer nanostructures with different thicknesses of Mg layers and the same thickness of ZrO2 layers are obtained via the ion-beam sputtering of two targets in an argon medium. The thickness of one bilayer (Mg + ZrO2) varies from 3.6 to 8.5 nm. It is found that using zirconium dioxide prevents the oxidation of the magnesium phase. An electric percolation threshold is observed when the morphology of magnesium layers changes (a transition from discrete to continuous morphology) as a result of an increase in the bilayer thickness. A change of the electrotransport mechanism is identified in the (Mg/ZrO2)52 multilayer nanostructures upon passing through the percolation threshold.

Аннотация: We consider light absorption in a germanium grating placed on top of photonic-crystalline substrate. Such a system supports an optical Tamm state decoupled from the continuous spectrum with its frequency within the photonic band gap. We have demonstrated that application of the Tamm state makes in possible to engineer extremely narrow absorber which provides a 100 % absorption in a semiconductor grating in the critical coupling regime. The proposed design may be used at both normal and oblique incidence at the telecom wavelength.

Аннотация: The magnetic resonance properties of a low-dimensional cobalt-Al2O3-germanium tunnel contact are studied in this work. The appearance of minima observed at low temperatures on both sides of the cobalt layer was found on the thermomagnetic curve. The value of the temperature minimum differs in magnitude on both sides of the cobalt layer. The position of the minimum in the temperature dependence of magnetization depends on the sample preparation technology. As a result of layer growth, at least two magnetic phases appear. One contribution is from the spins of ferromagnetic particles (cobalt particles with a hexagonal close packed lattice), and additional contributions from the magnetically disordered phase of fine cobalt particles and Co-Al2O3 compounds.

Заглавие : Mechanical activation of fullerene containing soot during extraction of higher and endohedral metallofullerenes
Место публикации : Fuller. Nanotub. Carbon Nanostruct. - 2022. - Vol. 30, Is. 5. - P.553-558. - ISSN 1536383X (ISSN), DOI 10.1080/1536383X.2021.1966421

Аннотация: For extraction of higher fullerenes and endohedral metallofullerenes (EMF) with yttrium from fullerene-containing carbon soot (soot) obtained by combined spraying of graphite and yttrium oxide powders in an arc plasma, we developed a device (Extractor*) that provides mechanical activation effects on agents combined with filtration. It has been shown that the soot recovery percentage of a mixture of higher fullerenes and EMF with different solvents (carbon disulfide, o-xylene, pyridine) and the EMF mass fraction in the mixture is significantly higher than in the extraction with a Soxhlet apparatus traditionally used for these purposes. The time spent on the extraction process is reduced significantly. Due to a known reaction with titanium chloride (TiCl4) and removal of a solution of empty fullerenes, subsequent bonding of EMF with yttrium into an insoluble complex directly in the extractor allows the product to be significantly enriched with EMF. In general, we were able to significantly reduce both the duration of extraction of the fullerenes mixture and EMF and the production of EMF separately.

Аннотация: Herein, the AC magnetoresistance (MR) in the silicon-on-insulator (SOI)-based Fe/Si/SiO2/p-Si structure is presented. The structure is used for fabricating a back-gate field-effect pseudo-metal-oxide-semiconductor field-effect transistor (MOSFET) device. The effects of the magnetic field and gate voltage on the transport characteristics of the device are investigated. Magnetoimpedance value of up to 100% is obtained due to recharging of the impurity and surface centers at the insulator/semiconductor interface. A resistance variation of up to 1000% is found, which is caused by the voltage applied to the gate and the field effect on the band structure of the sample. Combining the magnetic and electric fields, one can either change the absolute value of the AC resistance while having the MR fixed or change the sign and character of the field dependence of the MR. The observed effects can be used in the development of magnetic-field-driven SOI-based devices and high-frequency circuits.

Аннотация: This paper considers the photoelectrochemical characteristics of a composite porous TiO2 thin film with deposited plasmonic gold nanoparticles. The deposition of gold nanoparticles was carried out by the laser-induced chemical liquid-phase deposition (LCLD) method. The structural characteristics of the composite have been studied; it has been shown that the porous TiO2 film has a lattice related to the tetragonal system and is in the anatase phase. Gold nanoparticles form on the surface of a porous TiO2 film. A complex of photoelectrochemical measurements was carried out. It was shown that the deposition of plasmonic gold nanoparticles led to a significant increase in the photocurrent density by ~820%. The proposed concept is aimed at testing the method of forming a uniform layer of plasmonic gold nanoparticles on a porous TiO2 film, studying their photocatalytic properties for further scaling, and obtaining large area Au/TiO2/FTO photoelectrodes, including in the roll-to-roll process.

Аннотация: The article shows numerical calculation of the spectra for a metal-dielectric microcavity. The microcavity consists of a photonic crystal mirror, metallic mirror and a liquid crystal layer between them. It is shown that the system supports both symmetry-protected and Friedrich-Wintgen types of bound states in the continuum. The quality factor and position of resonant modes are effectively controlled by changing the system parameters or applying an external electric field to the liquid crystal layer.
