Through Silicon Vias With Invar Metal Conductor for High-Temperature Applications

Mikhail Asiatici, Göran Stemme

Through silicon vias (TSVs) are key enablers of 3-D integration technologies which, by vertically stacking and interconnecting multiple chips, achieve higher performances, lower power, and a smaller footprint. Copper is the most commonly used conductor to ...

Origin of the Strong Interaction between Polar Molecules and Copper(II) Paddle-Wheels in Metal Organic Frameworks

Berend Smit, Daniele Ongari, Davide Tiana

The copper paddle-wheel is the building unit of many metal organic frameworks. Because of the ability of the copper cations to attract polar molecules, copper paddle-wheels are promising for carbon dioxide adsorption and separation. They have therefore bee ...

Copper-catalysed cyanoalkylative cycloetherification of alkenes to 1,3-dihydroisobenzofurans: development and application to the synthesis of citalopram

Qian Wang, Jieping Zhu, Minh Tu Ha

A copper-catalysed cyanoalkylative cycloetherification of alkenes was developed. Heating a solution of substituted (2-vinylphenyl)methanol in MeCN/MeOH (v/v 7/3) in the presence of a catalytic amount of copper(II) tetrafluoroborate hydrate [Cu(BF4)26H2O], ...

Direct evidence for charge stripes in a layered cobalt oxide

Peter Babkevich, Paul Gregory Freeman, Mechthild Enderle

Recent experiments indicate that static stripe-like charge order is generic to the hole-doped copper oxide superconductors and competes with superconductivity. Here we show that a similar type of charge order is present in La-5/Sr-3(1)/3CoO4, an insulating ...

Luminescent Colloidal Semiconductor Nanocrystals Containing Copper: Synthesis, Photophysics, and Applications

Arianna Marchioro

Copper-doped semiconductors are classic phosphor materials that have been used in a variety of applications for many decades. Colloidal copper-doped semiconductor nanocrystals have recently attracted a great deal of interest because they combine the soluti ...

Mesoscopic Modeling and Experimental Investigations of the Last-Stage Solidification of Globular-Equiaxed Grains in Metallic Alloys

Christophe Mondoux

Hot tearing is a major defect of solidification processes and welding. It occurs in metallic alloys while they are in the semi-solid state and is caused by a lack of liquid feeding in the mushy zone to compensate solid network openings due to tensile and s ...

Solution Transformation of Cu2O into CuInS2 for Solar Water Splitting

Michael Graetzel, Jingshan Luo, Matthew Thomas Mayer, Stanley David Tilley, Marcel Roland Schreier, Ludmilla Steier

Though Cu2O has demonstrated high performance as a photocathode for solar water splitting, its band gap is too large for efficient use as the bottom cell in tandem configurations. Accordingly, copper chalcopyrites have recently attracted much attention for ...

A dimerization interface mediated by functionally critical residues creates interfacial disulfide bonds and copper sites in CueP

Matteo Dal Peraro, Luciano Andres Abriata

CueP confers bacterial copper resistance in the periplasm, particularly under anaerobic conditions, through an unknown mechanism. The only available structure and limited solution data suggest that CueP forms noncovalent timers in solution, whereas sequenc ...

Molecular dynamics simulations of apocupredoxins: insights into the formation and stabilization of copper sites under entatic control

Matteo Dal Peraro, Luciano Andres Abriata

Cupredoxins perform copper-mediated long-range electron transfer (ET) in biological systems. Their copper-binding sites have evolved to force copper ions into ET-competent systems with decreased reorganization energy, increased reduction potential, and a d ...
