Extraction of REE(III), U(VI), and Th(IV) from Nitric Acid Solutions with Carbamoylmethylphosphine Oxides Bearing an Additional Phosphoryl Group

Alexander N. Turanov, Vasilii K. Karandashev, Vladimir A. Khvostikov, Elena V. Sharova et autres

Abstract The extraction of trace amounts of U(VI), Th(IV), and REE(III) from HNO3 solutions with new carbamoylmethylphosphine oxides Ph2P(O)CH2C(O)N(Bu)CH2P(O)Bu2 and Bu2P(O)CH2C(O)N(Bu)CH2P(O)Bu2, containing a phosphoryl group in the amide moiety of the molecule, in dichloroethane has been studied. The stoichiometry of the extracted …

Use of Porphyrin Precursors as a Novel Approach for Detection of Mycobacterium tuberculosis

Oganes A. Ambartsumyan, Platon Eliseev, Olesya A. Skuredina, Ekaterina Y. Gosteva et autres

Tuberculosis remains one of the leading infectious diseases worldwide, which is why new approaches are being developed as a foundation for future diagnostic methods. One promising strategy relies on porphyrins as biomarkers for the detection of Mycobacterium tuberculosis using fluorescence spectroscopy. Previous …

New metal complexes of derivatives of natural porphyrins with gallium: Synthesis and spectral characteristics

A. A. Lelyukhova, Nikita V. Suvorov, Valentina D. Rumyantseva, Nikita Kirin et autres

Objectives. Porphyrins are known to selectively accumulate in tumor cells and exhibit photosensitizing properties. However, the use of free-base porphyrins is accompanied by side effects due to the slow elimination of such drugs from the body and long-term skin phototoxicity. One approach …

Accelerated interrupted aging and enhanced secondary precipitation in Al–Mg–Si–Cu alloys via electropulsing

Conghan Huang, Le Zong, Hao Zhong, Boris Straumal et autres

: Interrupted aging (IA) is a promising route for enhancing precipitate nucleation in age-hardenable alloys, but its industrial application is limited by the prolonged IA stage, owing to the trade-off between solute supersaturation and diffusion-controlled kinetics at low temperatures. Here, we replace …

Frequency control of superconducting resonators using integrated interferometers

I. E. Tarasova, Sergey V. Egorov, Ivan A. Nazhestkin, Sergey V. Bakurskiy et autres

Predictable frequency trimming of superconducting resonators at liquid-helium temperatures requires a tuning element whose usable range remains well defined despite screening currents and hysteresis. Here, we realize flux-controlled λ/4 coplanar-waveguide resonators terminated by two-junction DC superconducting quantum interference devices (SQUIDs) fabricated in …

Perfect Absorption by Metal-contacted Two-dimensional Systems with Ultra-proximate Reflectors

K. Kapralov, V. Atlasov, A. Khisameeva, В. Муравьев et autres

Electromagnetic absorbance by most two-dimensional electron systems is typically well below unity, which hinders both practical applications in photodetection and fundamental studies of their optical properties. Here, we show that a periodic structure comprised of narrow two-dimensional sections connected with wide perfectly …
