Optically pure P-stereogenic monophosphorus ligands containing a heterocyclic substituent have been prepared. They have been coordinated to Ru-η<sup>6</sup>-arene moieties in which the ligands act as mono- or bidentate. The complexes catalyse asymmetric transfer hydrogenation reactions with up to 70% ee.

CODRu(h3methylallyl)2 is a versatile starting material for the preparation of a wide range of chiral bisphosphines ruthenium(II) complexes: (P*P)Ru(h3methylallyl)2 2, Ru[X4(P*P)2] 3, and cationic monohydride ruthenium complex 4. A facile synthesis of new C2 electron-rich chiral phosphines, bis(phosphetano)benzene 8 and 1,1¢bis(phosphetano)ferrocene 10 is presented. Dynamic kinetic resolution was used for efficient syntheses of key components of the hexahydroazepane core 16 of balanol and of optically pure Boc-(2S,3R,3S)-iso-dolaproïne 19.

We have prepared a new bis(bipyridyl) ligand 1 based on a chiral 9,9´-spirobifluorene core in both enantiomerically pure forms. This ligand was found to undergo diastereoselective self-assembly to optically pure dinuclear coordination compounds upon coordination to copper(I) and silver(I) ions. Surprisingly, however, the resulting diastereomer was not found to be D2-symmetric which is usually found for similar bis(bidentate) ligands, but rather C2-symmetric with differently configurated metal centers.

In this work, organic–inorganic hybrids based on nanocrystalline indium oxide and ruthenium (II) heteroleptic complexes were used as sensitive materials for room temperature light-activated NO2 detection. In2O3 was obtained by chemical precipitation method and then annealed at three different temperatures (T = 300, 500, 700 °C) in order to investigate the influence of the microstructure of indium oxide on sensor characteristics of hybrid materials and on kinetics of the rise and fall of photoconductivity.

La métathèse des oléfines est une réaction emblématique de la chimie verte pour la formation de nouvelles doubles liaisons carbone-carbone. Permettant une grande économie d’atome et la réduction du nombre d’étapes de synthèse, cette réaction offre des atouts incontestables pour la production de molécules d’intérêts. Ainsi, une multitude de complexes de ruthénium ont été développés depuis les années 1990 avec pour objectif d’étendre les champs d’applications de la métathèse. Si des avancées majeures ont été accomplies au niveau de l’activité et de la stabilité de ces précatalyseurs, le contrôle

The combination of organic and inorganic materials forms unique composites with properties that neither of the two components provides. Such functional materials are considered innovative advanced materials that enable applications in many fields, including optics, electronics, separation membranes, protective coatings, catalysis, sensors, biotechnology, and others. The challenge of incorporating inorganic particles into an organic matrix still remains today, especially for nanoparticles, due to the difficulties in their dispersion, de-agglomeration and surface modification.

Graphene is one of the most promising carbon nanomaterial due to its excellent electrical, thermal, optical and mechanical properties. However, it is still very challenging to unlock its exotic properties and widely adopt it in real-world applications. In this paper, we introduces a new 3D graphene structure printing approach with pure graphene oxide material, better inter-layer bonding, and complex architecture printing capability. Various parameters related to this novel process are discussed in detail in order to improve the printability, reliability and accuracy. We have shown that the pri

Abstract An experimental study is conducted to determine the property fields of 40 MHz argon radio frequency inductively coupled plasma using optical emission spectroscopy. The pure argon plasma was operated at the input power of 0.3 kW and under atmospheric pressure. 29 atomic argon lines with upper level energies ranging from 12.9 to 15.5 eV, continuum emission and line width are used to evaluate plasma parameters such as temperature and electron number density. Since 40 MHz plasma is in almost complete nonequilibrium, the validaty and accuracy of most usual spectroscopic methods are questio

The crystal lattice of high-entropy alloys (HEAs) undergoes significant deformation, that is why HEAs have high strength, significant wear resistance and corrosion resistance in environments with high chemical activity [1]. This work was aimed at creating new heat-resistant high-entropy alloys, based on inexpensive elements and prepared from common master-alloys, studying their phase composition and structure, as well as determining their physical-mechanical properties. FeNiCrCuAl alloys do not contain such an expensive element as cobalt (Co), which is usually present in similar metallic syste
