The article publishes the results of X-ray fluorescence mapping of the alloy composition of a figured hanging weight from the Roman "fast" scales in the form of a male bust. The weight was found at the Eklizi-Burun sanctuary (southern part of the Mountainous Crimea). The figured shell of the weight is cast from high-tin bronze, which differs in tin content in different areas of the sculpture. It was possible to reveal an abnormally high content of tin (more than 35.6%) in the area on the front of the bust. The inner cavity is completely or partially filled with heavier lead, the splashes of which onto the surface were recorded using point-by-point X-ray analysis. The figured weight from the Eklizi-Burun sanctuary is probably evidence of one of the "early" cases, when the population of the Northern Black Sea region becoming familiar with relatively complex devices ("fast" scales) and technologies (casting on a lost wax model with a lead core) developed in the Roman Empire.

A convenient, stable, and non-toxic substance, tetrabutylammonium difluorotriphenylsilicate (TBAT), can be used as an organocatalyst in all stages of polymer lifetime: synthesis, modification, and recycling. The fluorine-containing initiator showed high activity in the polymerization of siloxanes compared to classic organocatalytic systems. Using kinetically controlled ROP, a high-molecular-weight PDMS (Mn up to 820 𝑘𝑔/𝑚𝑜𝑙) was prepared at room ...

A simple and atom-efficient way to prepare amides directly from carboxylic acids and nitroarenes was developed. Carbon monoxide as a sole reducing agent provides the ultimate selectivity of the protocol. A straightforward and selective way for the preparation of amides from nitroarenes and carboxylic acids using carbon monoxide as a reductant was developed. This protocol ...

Solubility is a crucial property of organic compounds, impacting their potential applications in synthetic chemistry, materials science and drug design. Moreover, in technological processes mixtures of solvents are often utilized, making the solubility assessment more complicated. Predicting solubility values in mixtures of solvents from a molecular structure can help to address this issue, although a ...

Heterostructures based on ZnO nanorods and CsPbBr3 nanocrystals were investigated for their potential as semiconductor SERS substrates. We found that ZnO morphology governs the efficiency of interfacial energy transfer, leading to enhanced photoluminescence under 390 nm excitation and a noticeable reduction of the bandgap in the composites. Raman analysis revealed a pronounced intensity enhancement and ...

Проведено квантово-химическое моделирование механизма экстракции Fe(III) из солянокислого раствора с использованием гидрофобных эвтектических растворителей на основе 1-октанола. Установлено, что путь реакции существенно различается в зависимости от того, является ли инертный компонент донором или акцептором водородной связи в димере с октанолом. На основе оценки прочности водородных связей показано, что более слабое взаимодействие между компонентами упрощает протекание ...

A new approach to managing the extraction properties of eutectic solvents based on aliphatic alcohols is proposed. Aliphatic alcohols, when functioning as hydrogen bond donors within a eutectic solvent, significantly enhance the solvent’s efficiency in extracting metal ions. Conversely, when the alcohol acts as a hydrogen bond acceptor, its extraction properties diminish. Molecular modelling reveals ...

The reactivity of polar vinyl monomers, unsaturated compounds containing functional groups, depends on the presence or absence of conjugation between the C=C bond and the neighbouring unsaturated moieties or donor heteroatoms. Conjugated polar vinyl monomers (acrylates, vinyl ethers, etc.) (co)polymerize upon free-radical initiation. The reaction is widely used to produce numerous polymer materials that qualitatively differ ...

Silica-supported chromium oxide catalysts, also named Phillips chromium catalysts (PCCs), provide more than half of the world’s production of high- and medium-density polyethylenes. PCCs are usually prepared in the Cr(VI)/SiO2 form, which is subjected to reductive activation. It has been explicitly proven that CO reduces Cr(VI) to Cr(II) species that initiate ethylene polymerization; ethylene activates ...
