Two pairing domes as Cu2+ varies to Cu3+

A Tale of Two Domes

Domes as a Prodigal Shape in Synthesis-Enhanced Parsers

Research on logic based bottom-up parsing in particular, around Constraint Handling Rule Grammars [3]is uncovering shape as an untapped fertile ground for natural language processing in general, and for bottom-up parsing and grammar induction in particular [1]. For instance, commonalities between shapes implicit in molecular biology strings and in natural language strings motivated an award win...

Synthesis and Characterization of Cu2(I,I), Cu2(I,II), and Cu2(II,II) Compounds Supported by Two Phthalazine-Based Ligands: Dramatic Influence of a Hydrophobic Pocket

The copper coordination chemistry of two phthalazine-based ligands of differing steric bulk was investigated. A family of dinuclear complexes were prepared from reactions Of Cu-2(bdptz)(MeCN)(2)](OTf)(2), 1(OTf)(2), where bdptz = 1,4-bis(2,2’-dipyridylmethyl)phthalazine. Treatment of 1(OTf)(2) with NaO2CCH3 afforded the class I mixed-valent compound Cu-2(bdPtZ)(2)](OTf)(3), 2(OTf)(3), by dispro...

Evolution of fermion pairing from three to two dimensions.

We follow the evolution of fermion pairing in the dimensional crossover from three-dimensional to two-dimensional as a strongly interacting Fermi gas of ^{6}Li atoms becomes confined to a stack of two-dimensional layers formed by a one-dimensional optical lattice. Decreasing the dimensionality leads to the opening of a gap in radio-frequency spectra, even on the Bardeen-Cooper-Schrieffer side o...

Loading of Two Related Metal-Organic Frameworks (MOFs), [Cu2(bdc)2(dabco)] and [Cu2(ndc)2(dabco)], with Ferrocene

We have studied the loading of two related, similar porous metal-organic frameworks (MOFs) [Cu2(bdc)2(dabco)] (1), and [Cu2(ndc)2(dabco)] (2) with ferrocene by exposing bulk powder samples to the corresponding vapor. On the basis of powder X-ray diffraction data and molecular dynamics (MD) calculations we propose that each pore can store one ferrocene molecule. Despite the rather pronounced sim...
