The plastocyanin from Phaseolus vulgaris has been shown to consist of a single polypeptide chain of 100 residues to which 1 atom of copper is bound. This plastocyanin is the smallest copper-protein yet reported; its molecular weight is 10,690. The molar extinction coefficient (E& of the copper chromophore was shown to be 4.5 x 103. The copper content and molecular weight contrast with that of p...

We present the use of direct bonded copper (DBC) for the straightforward fabrication of high power atom chips. Atom chips using DBC have several benefits: excellent copper/substrate adhesion, high purity, thick (> 100 μm) copper layers, high substrate thermal conductivity, high aspect ratio wires, the potential for rapid (< 8 hr) fabrication, and three dimensional atom chip structures. Two mask...

The storage of copper by adult Merino sheep of normal copper status has been measured in liver biopsy samples drawn at weekly intervals following subcutaneous and intramuscular injections of copper glycine cerate (90 mg Cu) and aqueous suspensions of copper calcium ethylenediaminetetra-acetic acid (EDTA) and copper methionine complexes (each 100 mg Cu) . The glycine and EDTA preparations safely...

Minyoung Lee and Alan J. H. McGaughey Department of Mechanical Engineering, Carnegie Mellon University, Pittsburgh, Pennsylvania 15213, USA (Received 2 February 2011; published 29 April 2011) The energetics and kinetics of the c(2 × 2) to (2√2 ×√2)R45◦ missing-row reconstruction transition on the Cu(100) surface are investigated using density functional theory calculations. First, oxygen-molecu...
