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 ...

Single amino acid substitutions in the ATP-binding domain of ACVRL1, a key receptor in the bone morphogenetic protein (BMP) signaling pathway, are frequently classified as variants of uncertain significance (VUS), complicating molecular diagnosis for pulmonary arterial hypertension (PAH) and Hereditary Hemorrhagic Telangiectasia (HHT). Since aberrant ATP binding disrupts downstream SMAD1/5/8 phosphorylation, we employed molecular dynamics ...

Background Cardiac fibrosis represents a significant health burden, with endothelial dysfunction and damaged
perivascular microenvironment increasingly recognized as key contributors to fibrotic remodeling. The urokinase
plasminogen activator receptor (uPAR), a critical component of the urokinase system, plays a pivotal role in vascular
remodeling and fibrosis. While prior evidence indicates that uPAR deficiency leads to microvascular dysfunction and
perivascular fibrosis, ...

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 ...

The conformational mobility of the [8-EtO-8’-I-3,3’-Co(1,2-C2B9H10)2]− anion, which has been chosen as a model compound for many potential drugs based on cobalt bis(dicarbollide), was studied by 1H NMR spectroscopy, single crystal X-ray diffraction and quantum chemical calculations. According to the results of quantum chemical calculations, the most favourable conformation for [8-EtO-8’-I-3,3’-Co(1,2-C2B9H10)2]− is the transoid conformation, which is stabilized by one ...

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 ...

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 ...

The reaction of copper(I) phenylacetylide [PhC ≡ CCu]n with the 2-pyridylphosphines (tBu2PyP and Ph2PyP) offers a straightforward route to structurally diverse clusters. With tBu2PyP, a trinuclear cluster [Cu3(C ≡ CPh)3(tBu2PyP)3] featuring a Cu3 triangular was isolated. Surprisingly, the reaction of [PhC ≡ CCu]n with Ph2PyP yields two isomeric clusters [Cu4(C ≡ CPh)4(Ph2PyP)4] with tetrahedral or zigzag-arranged Cu4 cores. Upon prolonged storage in acetonitrile, the tetrahedral Cu4 cluster converts to ...
