Заглавие : A Challenge toward novel quaternary sulfides SrLnCuS3 (Ln = La, Nd, Tm): Unraveling synthetic pathways, structures and properties
Место публикации : Int. J. Mol. Sci. - 2022. - Vol. 23, Is. 20. - Ст.12438. - ISSN 14220067 (ISSN), DOI 10.3390/ijms232012438
Примечания : Cited References: 62. - The research was funded by the Tyumen Oblast Government, as part of the West-Siberian Interregional Science and Education Center’s project No. 89-DON (3).

Аннотация: We report on the novel heterometallic quaternary sulfides SrLnCuS3 (Ln = La, Nd, Tm), obtained as both single crystals and powdered samples. The structures of both the single crystal and powdered samples of SrLaCuS3 and SrNdCuS3 belong to the orthorhombic space group Pnma but are of different structural types, while both samples of SrTmCuS3 crystallize in the orthorhombic space group Cmcm with the structural type KZrCuS3. Three-dimensional crystal structures of SrLaCuS3 and SrNdCuS3 are formed from the (Sr/Ln)S7 capped trigonal prisms and CuS4 tetrahedra. In SrLaCuS3, alternating 2D layers are stacked, while the main backbone of the structure of SrNdCuS3 is a polymeric 3D framework [(Sr/Ln)S7]n, strengthened by 1D polymeric chains (CuS4)n with 1D channels, filled by the other Sr2+/Ln3+ cations, which, in turn, form 1D dimeric ribbons. A 3D crystal structure of SrTmCuS3 is constructed from the SrS6 trigonal prisms, TmS6 octahedra and CuS4 tetrahedra. The latter two polyhedra are packed together into 2D layers, which are separated by 1D chains (SrS6)n and 1D free channels. In both crystal structures of SrLaCuS3 obtained in this work, the crystallographic positions of strontium and lanthanum were partially mixed, while only in the structure of SrNdCuS3, solved from the powder X-ray diffraction data, were the crystallographic positions of strontium and neodymium partially mixed. Band gaps of SrLnCuS3 (Ln = La, Nd, Tm) were found to be 1.86, 1.94 and 2.57 eV, respectively. Both SrNdCuS3 and SrTmCuS3 were found to be paramagnetic at 20-300 K, with the experimental magnetic characteristics being in good agreement with the corresponding calculated parameters.

Заглавие : A high-selectivity waveguide bandpass filter with interference suppression by more than 120 dB in rejection band
Колич.характеристики :5 с
Место публикации : Tech. Phys. Lett. - 2023. - Vol. 49, Is. 5. - P.72-76. - ISSN 10637850 (ISSN), DOI 10.21883/TPL.2023.05.56034.19541. - ISSN 10906533 (eISSN)
Примечания : Cited References: 10. - This study was carried out under agreement No. 470 dated August 30, 2022, between the Kirensky Institute of Physics (Siberian Branch, Russian Academy of Sciences), the Regional Science Foundation, and ”AO ”NPP ”Radiosvyaz“ as part of a competitive tender of research-andengineering and innovative projects for the first climatological research and education center ”Yenisey Siberia“
Аннотация: The design of a 10th-order waveguide bandpass filter with an additional inductive cross-coupling between non-adjacent resonators has been proposed and studied. An inductive coupling is formed by a U-shaped conductor structure with grounded ends that is formed in the filter cover. This method of cross-coupling organization ensures not only the temperature stability of the characteristics, but also the manufacturability of the structure. The high selectivity of the device is achieved by both the attenuation poles located near the passband, as well as the level of suppression in the stopbands, exceeding 120 dB. The passband loss of the fabricated filter is ~ 0.8 dB at its central frequency f0=18.2 GHz and relative bandwidth Δf/f0=1.5%. The small dimensions (135 x 30 x 10 mm) and the weight of about 200 g of the device, with simultaneously high electrical characteristics show the promise of its use, for example, in on-board and ground-based space communication systems.

Заглавие : Alteration of the aggregation stability of quantum dots by irradiation
Коллективы : International Conference on Metamaterials and Nanophotonics

Аннотация: The influence of weak irradiation on the aggregation stability of quantum dots is considered. It was shown that under combined UV and visible light irradiation, a gradual increase in spontaneous aggregation takes place, testifying decrease in stabilizing potential barrier height. Thereby, the laser-induced controllable self-assembly of CdTe QDs is recommended to be performed over a time period between 80 and 100 min after the beginning of low intensity irradiation under conditions equivalent to those applied in this study.

Аннотация: Novel nanoscale bioconjugates combining unique plasmonic photothermal properties of gold nanoparticles (AuNPs) with targeted delivery using cell-specific DNA aptamers have a tremendous potential for medical diagnostics and therapy of many cell-based diseases. In this study, we demonstrate the high anti-cancer activity of aptamer-conjugated, 37-nm spherical gold nanoparticles toward Ehrlich carcinoma in tumor-bearing mice after photothermal treatment. The synthetic anti-tumor aptamers bring the nanoparticles precisely to the desired cells and selectively eliminate cancer cells after the subsequent laser treatment. To prove tumor eradication, we used positron emission tomography (PET) utilizing radioactive glucose and computer tomography, followed by histological analysis of cancer tissue. Three injections of aptamer-conjugated AuNPs and 5 min of laser irradiations are enough to make the tumor undetectable by PET. Histological analysis proves PET results and shows lower damage of healthy tissue in addition to a higher treatment efficiency and selectivity of the gold nanoparticles functionalized with aptamers in comparison to control experiments using free unconjugated nanoparticles.

Заглавие : Brownian dynamics of the self-assembly of complex nanostructures in the field of quasi-resonant laser radiation
Место публикации : Photonics Nanostruc. Fundam. Appl. - 2019. - Vol. 35. - Ст.100707. - ISSN 15694410 (ISSN), DOI 10.1016/j.photonics.2019.100707

Аннотация: Self-assembly of nanoparticles under the action of laser field can be an universal method for the formation of nanostructures with specific properties for application in sensorics and nanophotonics. For prognosis of the self-assembly processes, the model of movement of an ensemble of nanoparticles in a viscous media under the action of laser radiation with the account for interaction of laser-induced polarizations and Brownian dynamics is developed. This model is applied to the investigation of the self-assembly process of a triple of nanoparticles into three-particle structure with a predetermined geometry.Two specific cases of formation of nanostructure from a preliminarily formed pair of particles are studied: either for the pair fixed in space or from the unfixed pair of nanoparticles. The geometry of resulting nanostructures is shown to be determined by the polarization direction of laser radiation and the laser wavelength. Under proper choice of these parameters the formation of structures is shown to be highly efficient. E. g., maximum probability of structures formation is as hig as 36–46% per single laser pulse of 10 ns duration. © 2019 Elsevier B.V.

Аннотация: Cerenkov nonlinear diffraction of femtosecond pulses in one-dimensional nonlinear photonic crystal of strontium tetraborate was studied theoretically and experimentally in both frequency and time domains. Spectral features of second harmonic radiation were measured in the course of mapping the nonlinear photonic crystal structure. The local second harmonic spectrum demonstrates complex angular behavior within the beam cross section. The spectral width of the second harmonic radiation is found to be fundamental beam size-dependent, and optimal focusing should be used for exact conversion of the fundamental spectrum into the second harmonic one. Experimental results are in excellent agreement with calculations. Maximum second harmonic generation efficiency was up to 2.1% at pumping by a femtosecond oscillator.
