It has come to our attention that the following sentence contains an error: “However, while octahedra in MIL-53 are cis-connected, CAU-10 trans-connected.” The words “cis” and “trans” should be swapped read trans-connected, cis-connected.”

Improved via connections i n structures of YBa,Cu,07.,/SrTi0,/YBa,Cu,0,, (YBCO /STO/ YBCO) multilayers have been made using a combined HF wet-etching and ion-mil l ing process. The critical current density Jc of the via is as high as 2 x l o 6 A/cm2 at 76 K, and i s dominated by edge contacts in the ab-plane. YBCO and Sr,AlNbO, (SAN) multilayer test circuits were also made with this process. Th...

Ferrocene is strongly adsorbed by the highly porous metal-organic framework compound [Al(OH)(bdc)l], (MIL-53; bdc = 1,4-benzenedicarboxylate). The structure of the crystalline phase {[Fe(eta5-C5H5)2][Al(OH)(bdc)]2}x, was determined by X-ray powder diffraction and Rietveld methods. The ferrocene molecules are arranged in a 1D chain-like fashion and their cyclopentadienyl rings are oriented almos...

We provide a general thermodynamic framework for the understanding of guest-induced structural transitions in hybrid organic-inorganic materials. The method is based on the analysis of experimental adsorption isotherms. It allows the determination of the free energy differences between host structures involved in guest-induced transitions, especially hard to obtain experimentally. We discuss th...

Polar metal-organic frameworks have potential applications as functional non-linear optical, piezoelectric, pyroelectric and ferroelectric materials. Using second harmonic generation microscopy we found that fluoride doping of the microporous iron(iii) terephthalate MOF MIL-53(Fe) induces a polar organization in its structure, which was not previously detected with XRD. The polar order is only ...

The Upper Jurassic Mantos Blancos copper deposit (500 Mt at 1.0% Cu), located in the Coastal Range of northern Chile, displays two superimposed hydrothermal events. An older phyllic alteration probably related to felsic magmatic–hydrothermal brecciation at ∼155 Ma, and younger (141–142 Ma) potassic, propylitic, and sodic alterations, coeval with dioritic and granodioritic stocks and sills, and ...

A force field is proposed for the flexible metal-organic framework MIL-53(Al), which is calibrated using density functional theory calculations on nonperiodic clusters. The force field has three main contributions: an electrostatic term based on atomic charges derived with a modified Hirshfeld-I method, a van der Waals (vdW) term with parameters taken from the MM3 model, and a valence force fie...
