Заглавие : Optical coupled-mode theory for dielectric solids of revolution
Место публикации : Phys. Rev. A. - 2023. - Vol. 107, Is. 4. - Ст.043506. - ISSN 24699926 (ISSN), DOI 10.1103/PhysRevA.107.043506. - ISSN 24699934 (eISSN)

Аннотация: We propose a single resonance coupled-mode approach to light scattering by dielectric solids of revolution. By using a biorthogonal decomposition of the S matrix found with the extended boundary condition method we derived all parameters required for application of the temporal coupled-mode theory in a closed form. The proposed approach allows for constructing a frequency-dependent Fano response due to a single resonance after the full-wave solution has been found at a single incident frequency.

Заглавие : The effect of copper and iron adsorption on the catalytic performance of alumina nanofiber / nanodiamond composite in sensing applications
Место публикации : J. Phys. Chem. Solids. - 2022. - Vol. 167. - Ст.110785. - ISSN 00223697 (ISSN), DOI 10.1016/j.jpcs.2022.110785

Аннотация: Phenolic compounds are common environmental pollutants, which are used in many industries and contaminate water environment due to industrial wastewater discharge. Presently, there is an increasing demand for the development and improvement of inexpensive, easy-to-use analytical tools for in-situ detection of phenolic compounds. In this work, we investigate the effect of adsorption of Cu2+ and Fe2+ ions on the catalytic activity of a composite material based on alumina nanofibers (ANF) and detonation nanodiamonds (DND) in the co-oxidation of phenols with 4-aminoantipyrine in the presence of hydrogen peroxide. We have found more than two-fold increase of the catalytic activity for ANF + DND + Cu composite, while the activity of ANF + DND + Fe composite is found to decrease by several times in comparison with the original ANF + DND material. The results of FTIR analysis indicate that the adsorption of iron ions occurs with the formation of hydroxide surface groups and hydrogen bonds, which apparently block their catalytic activity in the Fenton redox cycle. The higher catalytic performance of AND + DND composite functionalized with copper ions makes it possible to detect two times lower concentrations of analytes (phenol and 4-chlorophenol) in comparison with the original composite. It is shown that the AND + DND + Cu composite provides a linear yield of the co-oxidation reaction product in a wide range of analyte concentrations (0.25–100 μM for phenol and 0.5–25 μM for 4-chlorophenol). Model experiments demonstrate the applicability of copper-functionalized composite as a reusable sensor for the determination of phenol in aqueous samples.

Аннотация: In this work, we investigated the ferromagnetic resonance spectra of metal/carbon composite coatings. FeC and NiC coatings were synthesized by electroless deposition using polysaccharide arabinogalactan. An analysis of the angular dependences of the resonance field showed that the coatings consist of three magnetic phases separated by a nonmagnetic phase of carbon.

Заглавие : Multiple-quantum NMR spectroscopy and quantum information spreading control in the spin systems of solids
Место публикации : J. Exp. Theor. Phys. - 2022. - Vol. 135, Is. 5. - P.752-761. - ISSN 10637761 (ISSN), DOI 10.1134/S1063776122110139. - ISSN 10906509 (eISSN)

Аннотация: Multiple-quantum (MQ) solid-state NMR spectroscopy allows the growth of multiple-spin correlations and, thus, the spreading of quantum information in the object under study to be observed. Recently, in [11] it was proposed to control this process through a controlled perturbation added to the effective Hamiltonian that causes degradation of correlated spin clusters with a rate determined by the number of spins K in a cluster. However, this perturbation can also lead to degradation whose rate is determined by the coherence order M. In this paper, to investigate the influence of a small added perturbation, we used an expansion into orthogonal operators that allowed the cluster size distribution to be taken into account. In our calculations we realized a simple model with known amplitudes of the expansion into a complete set of orthogonal operators in the absence of a perturbation. We performed numerical calculations of the “preparation time” dependences of the MQ spectra, their second moments, and the coherence orders at which the MQ spectra decrease by a factor of e as well as the average correlated spin cluster sizes K¯. The coherence-order-dependent contribution to the degradation is shown to change the shape of the MQ spectrum. In particular, as the preparation time increases, the MQ spectrum can be stabilized, while the growth of K¯ is retained. Due to the change in the shape of the MQ spectrum, the relations of its characteristics to the number K¯ change compared to those for the Gaussian function (traditionally used to process the experiments). These changes should be taken into account when studying the spreading of quantum information through MQ spectroscopy.

Заглавие : Magnetic resonance properties of low-dimensional cobalt – Al2O3-germanium tunnel contacts
Место публикации : Magn. Reson. Solids. - 2022. - Vol. 24, Is. 2. - Ст.22201. - ISSN 20725981 (ISSN), DOI 10.26907/mrsej-22201

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 : Heat capacity and thermal expansion of nanosized ferroelectric (NH4)2SO4 embedded in borosilicate glasses
Место публикации : J. Non-Cryst. Solids. - 2022. - Vol. 597. - Ст.121935. - ISSN 00223093 (ISSN), DOI 10.1016/j.jnoncrysol.2022.121935
Примечания : Cited References: 29. - The authors are grateful to Dr. Ewa Rysiakiewicz-Pasek (Wroclaw University of Science and Technology, Poland) for the preparation and characterization of borosilicate glasses. X-ray and dilatometric data were obtained using the equipment of Krasnoyarsk Regional Center of Research Equipment of Federal Research Center “Krasnoyarsk Science Center SB RAS”
Аннотация: The thermal properties of nanocomposites obtained by incorporating a ferroelectric (NH4)2SO4 (AS) into porous glasses (PG) was studied for the first time. X-ray diffraction studies showed a strong increase in the ratio of the size of nanocrystallites grown in glass matrices to pore size, dcryst/ dpore = 0.47→1.50→5.00, with a decrease in dpore = 320→46→7 nm. Calorimetric and dilatometric measurements showed a change from a first-order phase transition in AS single crystal to a second-order transformation in AS nanocrystallites. A restricted geometry also led to a significant decrease in the anomalous entropy in AS+PG samples compared to AS (J/mol∙K): 17.7 (AS)→12.4 (AS+PG320)→10.4 (AS+PG46)→8.1 (AS+PG7). A discussion of the nontrivial behavior of the phase transition temperature in embedded AS was carried out using the degree of PG filling, the ratio dcryst/dpore, texture, and the volumetric and linear baric coefficients for the bulk AS.

Аннотация: Needle-shape single crystals of Mn2.25Co0.75BO5 ludwigite were synthesized by the flux technique and investigated by means of X-ray diffraction, static magnetic susceptibility and specific heat measurements. Magnetization and specific heat experiments showed the presence of ferrimagnetic ordering near TN≃61K. Below this temperature the magnetic properties demonstrated the angular dependence and the high magnetic hardness in a magnetic field applied perpendicular to the crystallographic c axis, which is similar to other cobalt-containing ludwigites. The effective magnetic moment per magnetic ion 4.8μB was calculated from the paramagnetic data. Analysis of the phonon contribution to the specific heat allowed to distinguish the magnetic contribution CM, which has two features. One of which was observed at TN and can be attributed to strong exchange interactions between spins of magnetic ions. The second one at T = 11.6 K is due to the effect of the ligands crystal field on a magnetic ion with S›1/2.
