We use a subsample of co-detections of the ACT and MaDCoWS cluster catalogs to verify the predicted relation between the observed X-ray flux FX in the 0.5−2 keV band and the cluster mass M500c for halos at z > 0.6 − 0.7. We modified this relation by introducing a correction coefficient, η, which is supposed to encapsulate factors associated with a particular method of flux ...

To date, the design of stable panchromatic metal complexes simultaneously exhibiting reversible redox behavior remains a challenging endeavor, underscoring the need for new ligand platforms to expand their absorption spectrum. In this study, we report the synthesis and characterization of octahedral bis-cyclometalated iridium(III) complexes with redox-active o-semiquinone/o-iminosemiquinone ancillary ligands, which exhibit exceptional chemical stability and intense ...

Optimal conditions have been selected for the production of new phenol—azo dyes of different compositions, namely 2-phenyldiazenyl-4-(2-phenylpropan-2-yl)phenol and (2,6-dibromo)phenyldiazenyl-4-(2-phenylpropan-2-yl)phenol. The synthesized dyes were used for nucleophilic substitution with 3- and 4-nitrophthalonitrile to form 3/4-[2-phenyldiazenyl-4-(2-phenyl)propan-2-yl]phenoxy- and 3/4-[2-(2,6-dibromo)phenyldiazenyl]-4-(2-phenylpropan-2-yl)phenoxypthalonitriles. The metal complexes were synthesized by template condensation in a solution of the corresponding phthalonitrile with zinc or magnesium ...

С привлечением реакций диазотирования и азосочетания синтезирован 1-[4-(4-метоксифенил)азо]нафтол. Его использовали в качестве нуклеофила для получения 3- и 4-[(4-метоксифенилазо)-4-нафтокси]фталонитрилов. Темплатной конденсацией этих замещенных фталонитрилов с ацетатами цинка и магния синтезированы соответствующие металлокомплексы фталоцианинов. Определено влияние положения заместителя на процессы про тонирования и спектральные характеристики металлофталоцианинов. Изучены люминесцентные свойства синтезированных металлокомплексов и фотосенсибилизация синглетного кислорода. ...

Peripheral phenyl-substituted metal phthalocyanines with thio and oxa substitution in the spacer bridge fragment were obtained in the work. Spectroscopic properties were studied for the obtained complexes, and the main patterns of behavior and characteristics change depending on the solvent and the nature of the spacer atom. It is shown that the replacement of an oxygen ...

Tin-Vacancy (Sn-V) colour centres in diamond have a spin coherence time in the millisecond range at temperatures of 2 K, so they are promising to be used in diamond-based quantum optical devices. However, the incorporation of large Sn atoms into a dense diamond lattice is a non-trivial problem. The objective of our work is to use ...

This work is the first, to the best of our knowledge, to study synchrotron radiation (SR) from a massless charged electron based on the quantum theory of radiation using exact solutions of the Dirac equation in a constant magnetic field. The cases of (2 + 1)-dimensional and (3 + 1)-dimensional quantum electrodynamics are considered separately, and the ...

The neutrally charged silicon-vacancy defect (SiV0) is a colour centre in diamond with spin S = 1, a zero-phonon line (ZPL) at 946 nm and long spin coherence, which makes it a promising candidate for quantum network applications. For the proper performance of such colour centres, all of them must have identical optical characteristics. However, in practice, there ...

We examine the long-term (rest-frame time scales from a few months to ∼20 years) X-ray variability of a sample of 2344 X-ray bright quasars from the SDSS DR14Q Catalogue, based on the data of the SRG/eROSITA All-Sky Survey complemented for ∼7% of the sample by archival data from the XMM-Newton Serendipitous Source Catalogue. We characterise variability by a structure ...

We report the first measurement of the inclusive e+e−→bb¯→D±sX and e+e−→bb¯→D0/D¯0X cross sections in the energy range from 10.63 to 11.02. Based on these results, we determine σ(e+e−→B0sB¯0sX) and σ(e+e−→BB¯X) in the same energy range. We measure the fraction of B0s events at Υ(10860) to be fs=(22.0+2.0−2.1)%. We determine also the ratio of the B0s inclusive branching fractions B(B0s→D0/D¯0X)/B(B0s→D±sX)=0.416±0.018±0.092. The results are obtained using the data collected with the Belle detector at the KEKB ...

Разработан новый вариант метода диодной лазерной абсорбционной спектроскопии (ДЛАС) для определения температуры горячих зон. Метод основан на комбинации медленного сканирования частоты излучения зондирующего диодного лазера в окрестности линии поглощения тестовой молекулы среды и быстрой модуляции частоты излучения с амплитудой порядка ширины линии поглощения. Особенностью метода является использование двухлучевой дифференциальной схемы, логарифмическое преобразование сигналов и регистрация ...

Abstract: A new scheme for a calibration-free diode laser absorption spectroscopy (DLAS) sensor for
measuring the parameters of harsh zones is proposed. The key element of the scheme is a micro-prism
retroreflector (MPRR). The MPRR facilitates an increase in the mechanical stability of the sensor and
a decrease in the background thermal radiation in the hot areas of ...

Crystallization of a Na 2 O-K 2 O-Nb 2 O 5 -SiO 2 glass under thermal poling and subsequent annealing was studied by Raman spectroscopy and X-ray diffractometry. It was found that the poling and subsequent thermal treatment lead to partial crystallization of the poled region of the glass, which should be related with watering ...

Second-harmonic generation (SHG) is a well-known nonlinear spectroscopy method to probe electronic
structure, specifically, in transition metal dichalcogenide (TMDC) monolayers. This work investigates the
nonlinear dynamics of a strongly excited TMDC monolayer by solving the time evolution equations for the
density matrix. It is shown that the presence of excitons qualitatively changes the nonlinear dynamics leading,
in particular, to ...
