Thermal and Photoinduced Electron Transfer in Directional Bis(terpyridine)ruthenium(II)–(Bipyridine)platinum(II) Complexes
2013
Metalloligands L1 and L2 consisting of directional bis(terpyridine)ruthenium(II) units and bipyridine moieties were constructed by amide formation. From these metalloligands two Ru–Pt heterobimetallic complexes 1 and 2 were derived by a building-block method by means of platination with [PtCl2(dmso)2]. Both bimetallic complexes 1 and 2 feature metal-to-ligand charge transfer (MLCT) absorptions, and emission occurs at room temperature in fluid solution from 3MLCT(Ru) states in all cases. Energy transfer from platinum to ruthenium is observed in 2 but not in 1 (light harvesting). The one-electron-reduced species [1]– and [2]– were prepared by reduction of 1 and 2 with decamethylcobaltocene. E…
The Throne of God as a prototype of primacy in the Church and in creation
2019
This study emphasises the cosmic dimensions of the Church understood as the Throne of God, analysing its understanding in this way by the great writers and thinkers of the ancient world, for example, Philo the Alexandrine, Saint Dionysius the Areopagite and Saint Irene of Lyon. The reconstitution of all the cosmological contexts and understanding of the Throne of God inspired by the texts of the ancient authors is opening a very interesting perspective over the existence of the Church as a cosmic Throne of God and reassembling of all the heavenly and intelligible creations sustained and vivified by the primal light of God transmitted in this way towards the lower degrees of the heavenly ang…
Crystal structure of a low-spin poly[di-μ3-cyanido-di-μ2-cyanido-bis(μ2-2-ethylpyrazine)dicopper(I)iron(II)]
2019
In the title metal–organic framework, [Fe(C6H8N2)2{Cu(CN)2}2] n , the low-spin FeII ion lies at an inversion centre and displays an elongated octahedral [FeN6] coordination environment. The axial positions are occupied by two symmetry-related bridging 2-ethylpyrazine ligands, while the equatorial positions are occupied by four N atoms of two pairs of symmetry-related cyanide groups. The CuI centre is coordinated by three cyanide carbon atoms and one N atom of a bridging 2-ethylpyrazine molecule, which form a tetrahedral coordination environment. Two neighbouring Cu atoms have a short Cu...Cu contact [2.4662 (7) Å] and their coordination tetrahedra are connected through a common edge between…
Crystal structure of tricarbonyl(μ-diphenylphosphido-κ2P:P)(methyldiphenylsilyl-κSi)bis(triphenylphosphane-κP)iron(II)platinum(0)(Fe—Pt)
2015
The title compound belongs to the large family of heterodinuclear phosphide-bridged complexes. The Fe—Pt bond is of 2.7738 (4) Å and there is an unprecedented arrangement of the silyl ligand in a trans-position with respect to the metal–metal vector in the family of phosphide-bridged iron–platinum heterobimetallics.

La posizione assunta dall'architettura all'inizio del ventunesimo secolo è ambigua e così la forma degli edifici che ambiscono a convogliare significati. Il processo di radicale trasformazione dell’architettura, avvenuto sin dal primo Novecento, quale conseguenza della graduale sostituzione delle tecniche edilizie tradizionali con le tecniche “moderne”, ha subito un notevole slancio nell'ultimo ventennio, per effetto del crescente mutamento tecnologico. I materiali, le tecniche costruttive e l’innovazione tecnologica hanno condizionato sensibilmente ed irreversibilmente il pensiero architettonico, producendo in questi ultimi anni nuove espressività linguistiche del tutto “insolite” rispetto…
Fluctuating asymmetry and immune function in a field cricket
2004
Recently, fluctuating asymmetry (FA) of morphological traits has attracted great attention as a short-cut measure of individual quality. Whereas there is some evidence that FA of sexual ornaments is negatively associated with immune function, studies concerning FA and immune function in non-ornamental traits are absent. Here, we tested whether FA of three non-ornamental traits in hind limbs is related to male immune function in a population of the Mediterranean field cricket, Gryllus bimaculatus. As different measures of male immune function, we used encapsulation rate and lytic activity. We found that a composite measure of FA (cFA) was negatively related to encapsulation rate. However, ly…

Reduction and catalytic behaviour of heterobimetallic copper–lanthanide oxides
2008
Abstract The reduction of the heterobimetallic copper–lanthanide oxides 2CuO·CeO2 and 3CuO·Ln2CuO4 (Ln = La, Pr, Nd) was studied by H2-TG/DTA and H2-TPR. All systems exhibit two main reduction steps accompanied by mass losses in the temperature range 20–1000 °C. The first step was attributed to CuO reduction, whereas the second step is due either to copper reduction in the Ln2CuO4 phase with the concomitant formation of Ln2O3 or to the surface reduction of CeO2. The products were characterized by XRD, SEM, EDX, and BET techniques and are better described as supported copper type materials. They were active for the mesityl oxide (4-methyl-2-penten-2-one) gas phase hydrogenation.
