This study examined the local structural properties of CuI at low temperatures of 10-300 K by x-ray diffraction (XRD) and extended x-ray absorption fine structure (EXAFS) measurements at the Cu K edge. The XRD data were refined using two models, split (distorted zinc-blende structure) and non-split (zinc-blende structure), using a conventional Rietveld refinement combined with a maximum entropy...

The results are reported of the molecular dynamics simulations of the coherent static structure factor of molten CuI at 938 K using a polarizable ion model. This model is based on a rigid ion potential to which the many body interactions due to the anions induced polarization are added. The calculated structure factor reproduces the clear sharp prepeak observed in neutron diffraction data. The ...

Work on both the graphical user interface (GUI) and the conversational user interface (CUI) started at about the same time, about 40 years ago. The GUI was a lot easier to implement, and it made computing and information resources available to ordinary people—but over the years it has lost much of its simplicity and charm. The CUI has taken many more years to develop, requiring major scientific...

We report a combined experimental and theoretical investigation of MI(2)(-) (M = Cs, Cu, Ag, Au) to explore the chemical bonding in the group IA and IB diiodide complexes. Both photoelectron imaging and low-temperature photoelectron spectroscopy are applied to MI(2)(-) (M = Cs, Cu, Au), yielding vibrationally resolved spectra for CuI(2)(-) and AuI(2)(-) and accurate electron affinities, 4.52 ± ...

The azide-alkyne click polymerization (AACP) has emerged as a powerful tool for the synthesis of functional polytriazoles. While, for the Cu(I)-catalyzed AACP, the removal of the catalytic Cu(I) species from the resulting polytriazoles is difficult, and the research on the recyclability and reusability of the catalyst remains intact. Herein, we reported the first example of using recyclable and...

Riassunto: Negli ultimi anni molti studi sono stati condotti al fine di valutare la presenza di una eventuale associazione tra inquinamento dell’aria e mortalità. La relazione tra le concentrazioni di inquinanti e mortalità (o morbosità) nel medesimo giorno, o nei giorni successivi, viene usualmente specificata mediante modelli di regressione in cui la variabile di risposta è il numero di morti...

Photoinduced, copper-catalyzed cross-coupling can offer a complementary approach to thermal (non-photoinduced) methods for generating C-X (X = C, N, O, S, etc.) bonds. In this report, we describe the first detailed mechanistic investigation of one of the processes that we have developed, specifically, the (stoichiometric) coupling of a copper-thiolate with an aryl iodide. In particular, we focu...

The preparation of Pt(ii) complexes of the type trans-L2Pt(Ar)Cl, L2Pt(Ar)2, and L2Pt(Ar)(Ar') (L = PBu3, Ar = arylene) by CuI catalyzed reaction of cis-(PBu3)2PtCl2 with aryl-stannanes is reported. The reactions proceed at 25-60 °C in moderate to good yields. The reaction is demonstrated to occur with phenyl- and 2-thienyl-stannanes that include a variety of functionality, and all of the resul...
