Stable gold alloy electrodeposits

Ligand Protected Gold Alloy Clusters as Superatoms

Density functional study of the experimentally observed ligand-protected gold alloy clusters reveal the same stabilization mechanism as in ligand protected pure AuN: the delocalized s-electron subsystem of a high symmetry metal core exhibits a shell closing. On the basis of this observation it is predicted that the substitution of a single Au atom in the well-known Au25(SR)18 compound with Pd, ...

CHARACTERIZATION OF COBALT-HARDENED GOLD ELECTRODEPOSITS BY Co57-Fe57 MÖSSBAUER SPECTROSCOPY

Recent Advances in Superhydrophobic Electrodeposits

In this review, we present an extensive summary of research on superhydrophobic electrodeposits reported in the literature over the past decade. As a synthesis technique, electrodeposition is a simple and scalable process to produce non-wetting metal surfaces. There are three main categories of superhydrophobic surfaces made by electrodeposition: (i) electrodeposits that are inherently non-wett...

Patterning metallic electrodeposits with magnet arrays

The influence of a pattern of a magnetic field on the structure of metal deposits at the cathode of a small electrochemical cell is investigated for cobalt, nickel, copper, and zinc. The different magnetic properties of the ions in their oxidized and reduced states, together with the influence on the patterned electrodeposits of variables, including the structure of the array of small magnets u...

Stable gold(III) complexes with thiosemicarbazone derivatives.

Novel thiosemicarbazonato complexes of gold(III) have been prepared from reactions of [Au(damp-C1,N)Cl2(damp- = 2-(N,N-dimethylaminomethyl)phenyl) or [NBu4][AuCl4] with 2-pyridineformamide thiosemicarbazones (HL). The thiosemicarbazones deprotonate and coordinate as mononegative, tridentate NNS ligands to gold to give [Au(Hdamp-C1)(L)]Cl2 or [AuCl(L)]Cl complexes. The organometallic damp- ligan...
