Microstructure and Non-Metallic Inclusion Modification in Steel Deoxidized by Complex Fe-Si-Mn-Al Alloy

This study evaluates the effects of semi-industrial and synthetic Fe–Si–Mn–Al deoxidizers on the microstructure, non-metallic inclusions, and hardness of St3 steel. Seven complex alloys with different Fe, Si, Mn, and Al contents were produced and compared with conventional FeSi–F...

Optimal Extrapolation of the Derivative of a Polynomial Approximately Defined on the Lemniscate

Abstract We study the problem of optimal extrapolation (optimal recovery) of the derivative of a polynomial defined with an error on a compact set in the complex plane when the compact set is a lemniscate. Along with the extrapolation problem, we consider a related sharp inequali...

Intrinsically Conductive Films of Ag2Te Nanocrystals for Broadband Infrared Photodetection beyond 2000 nm

Abstract We report a rapid, up-scalable synthesis in an aprotic solvent to obtain Ag2Te nanocrystals that are intrinsically capped with a short, conductive thiol ligand, making them suitable for optoelectronic applications. The simultaneous use of labile and stable tellurium prec...

Freshwater Mollusks of the Upper Reaches of the Konda River Basin (Western Siberia): Species Composition, Distribution Patterns and Insights on Their Phylogeography

The taxonomic composition and zoogeographic characteristics of the malacofauna of the upper Konda River basin, a major left tributary of the Irtysh River within the taiga zone of Western Siberia, were identified. A total of 27 species of freshwater mollusks were recorded, includi...

First record of Ambulyx japonica Rothschild, 1894 from Russia (Lepidoptera: Sphingidae)

Ambulyx japonica Rothschild, 1894 is reported from Russia for the first time. A single male specimen was collected in Kajmanovka village, Primorsky Krai. Therefore, the Sphingidae fauna of Russia currently comprises 69 species belonging to 34 genera.

Cobalt Carbonyl as a Solid CO(g) Source for the Synthesis of Novel Coumarin Derivatives and Biaryl Ketones by Palladium‐Catalyzed Carbonylative Suzuki–Miyaura Reaction

We herein report an atom‐economical, facile, and efficient approach developed for synthesizing a variety of C‐7 carbonylated coumarin derivatives and biaryl ketones in good‐to‐excellent yields. The use of aryl fluorosulfates as an atom‐economical electrophilic coupling partner an...

Methodology of the main transport network creation and development of the European and Cisural North of Russia

Research in the field of improving transport efficiency, including the development of transport networks, is relevant at the state, regional and local levels. The improvement of the main transport network of the region is associated with its creation (construction of new network...
