An experimental and theoretical study of a heptacoordinated tungsten(VI) complex of a noninnocent phenylenediamine bis(phenolate) ligand
2018
Abstract [W(N2O2)(HN2O2)] (H4N2O2 = N,N′-bis(3,5-di-tert-butyl-2-hydroxyphenyl)-1,2-phenylenediamine) with a noninnocent ligand was formed by reaction of the alkoxide precursor [W(eg)3] (eg = the 1,2-ethanediolate dianion) with two equivalents of ligand. The phenol groups on one of the ligands are completely deprotonated and the ligand coordinates in a tetradentate fashion, whereas the other ligand is tridentate with one phenol having an intact OH group. The molecular structure, magnetic measurements, EPR spectroscopy, and density functional theory calculations indicate that the complex is a stable radical with the odd electron situated on the tridentate amidophenoxide ligand. The formal ox…

Kinetic evidence for the incorporation of the [(pentamethylcyclopentadienyl) (2,2′-bipyridyl)(aquo)rhodium(III)] complex into DPPC vesicles
2008
Abstract The binding of the [(pentamethylcyclopentadienyl) (2,2′-bipyridyl)(aquo)rhodium(III)] complex [Cp*RhIII(bpy)H2O]2+, to l -α-dipalmitoylphosphatidyl choline (DPPC) vesicles has been estimated by studying the kinetics of the electron transfer reaction between the rhodium(III) complex and formiate ions. Kinetic measurements carried out under anaerobic conditions in absence and presence of DPPC show that the total reaction is composed of two steps. The rate of the first reaction increases with the phospholipid concentration, while that of the second process is independent of the concentration of DPPC. This is consistent with a reaction, where the two reacting species are partitioned be…
Thermodynamically driven self-assembly of pyridinearene to hexameric capsules
2019
Pyridinearene macrocycles have previously shown unique host–guest properties in their capsular dimers including endo complexation of neutral molecules and exo complexation of anions. Here, we demonstrate for the first time the formation of hydrogen bonded hexamer of tetraisobutyl-octahydroxypyridinearene in all three states of matter – gas phase, solution and solid-state. Cationic tris(bipyridine)ruthenium(II) template was found to stabilize the hexamer in gas phase, whereas solvent molecules do this in condensed phases. In solution, the capsular hexamer was found to be the thermodynamically favoured self-assembly product and transition from dimer to hexamer occurred in course of time. The …
Installazioni idrauliche nell’area sacra a Sud del tempio di Zeus Olympios ad Agrigento
2020
This paper will test the relationship between water and cult in the southern part of the sanctuary of Zeus Olympios at Agrigento. The most singular feature of this area is a monumental pool, besides some cisterns, buildings and a small oikos temple. The sacred area was investigated during the 20th century by E. Gabrici and E. De Miro and was referred to a chthonian cult, without deepening the features and modalities of ritual activities. Besides, it was not considered at all as a part of the sanctuary of Zeus, depending on the late chronology assigned to the main buildings. After having defined the character of the context through an analysis of the architectural remains, the votive and rit…
An IPMSM torque/weight and torque/moment of inertia ratio optimization
2014
In this paper, a torque/weight and torque/moment of inertia ratio optimization procedure for interior permanent magnet syncronous motors (IPMSMs) is presented. More in detail, a performance comparison between several IPMSM rotor structures has been carried out in order to determine the optimum geometry that can maximize the torque/weight and torque/moment of inertia ratios. A commercial motor, with known electrical and mechanical characteristics, has been taken as reference. Its rotor structure has been modified several times, obtaining different rotor geometries and, therefore, many IPMSM models with different electrical and mechanical characteristics. The finite element method (FEM) analy…
Cadmium Metal–Organic Frameworks Based on Ditopic Triazamacrocyclic Linkers: Unusual Structural Features and Selective CO 2 Capture
2017
International audience; Two three-dimensional cadmium metal organic frameworks with general formula [Cd-2(L-1)(H2O)(3)](NO3)(0.7)(HCOO)(0.2)Br-0.1 (Cd2L1, L-1 = 1,4,7-tris(4-carboxybenzy1)-1,4,7-triazacyclononane) and Cd(HL2)(H2O)(2) (CdL2, L-2 = 1,4,7-tris(3-(4-benzoate)prop-2-yn-1-yl)-1,4,7-triazacydononane) based on 1,4,7-triazacyclononane N-functionalized by different arylcarboxylic acids were prepared under solvothermal conditions and characterized by single crystal X-ray analysis and porosity measurements. The crystal structure of Cd2L1 reveals a cationic net with a bcs topology,. and nodes are constituted by dinuclear cadmium complexes, in which each cadmium atom adopts a hexacoordin…
Zirgs latviešu tradicionālajā un mūsdienu kultūrā
2017
Maģistra darbs “Zirgs latviešu tradicionālajā un mūsdienu kultūrā” ir pētījums par zirga lomu latviešu kultūrvēsturiskajā, simboliskajā un mitoloģiskajā apziņā, mēģinājums izsekot tam, kā tā mainījusies cauri laikam. Darba trīs daļās analizēta zirga semantēma no senākajiem laikiem līdz mūsdienām – pirmā veltīta zirgam indoeiropiešu un baltu kultūrā, gan vēsturiskajā, gan mitoloģiskajā aspektā. Otrajā daļā aplūkots zirgs latviešu tradicionālajā kultūrā, par pamatu ņemot latviešu tautas dziesmas un padziļināti aplūkojot zirgu mītiskajā izpratnē, kā arī pievēršoties iepriekš latviešu folkloristikā nepētītam, ar zirgu saistītai reālijai – stallim. Trešā daļa apskata zirgu mūsdienu cilvēku priek…
