The Surface of Copper-Nickel Catalyst. II. Adsorption of Hydrogen on Copper, Nickel, and Copper-Nickel Catalysts

Nickel Plated Copper Heat Spreader Surface Characteristics

Nickel plated copper heat spreader acts as a medium to dissipate heat from silicon die towards heat-sink. Electroless nickel plating requires catalytic activation before the nickel can be deposited onto copper. Different catalytic activation techniques such as galvanic initiation and thin nickel-copper electrodeposition have diverse impact on the thermal performance of the heat spreader. Surfac...

Synthesis and characterization of Nickel Copper Ferrite

Nano size nickel copper ferrite powders (NiCuFe2O4) have been prepared by a prepared by Co precipitation method. The resulting powders were characterized by X-ray diffraction (XRD), Scanning electron microscope (SEM).The result showed nanosize nickel copper ferrite(35.65nm). The powders showed extensive XRD line broadening and sizes of crystals observed from the XRD line broadening was35.65 nm,...

Heteroleptic bis(dipyrrinato)copper(II) and nickel(II) complexes.

Heteroleptic bis(dipyrrinato)copper(II) and nickel(II) complexes are synthesized. Their structures are determined by X-ray diffraction analysis, and their properties are investigated by using cyclic voltammetry, chronocoulometry, and UV/vis absorption spectroscopy.

TEMPLATE SYNTHESIS, CHARACTERIZATION OF HIGHLY UNSYMMETRICAL TETRADENTATE SCHIFF BASE COMPLEXES OF NICKEL (II) AND COPPER (II)

Nickel (II) and copper (II) complexes of highly unsymmetrical tetradentate Schiff base have been synthesized by the template reaction of half-units N-(1-hydroxy-2-acetonaphtone)-1-amino-2-phenyleneimine (HL) and N-(2-hydroxyacetophenone)-1-amino-2-phenyleneimine (HL1) with the glyoxalphenylhydrazone. The complexes have been characterized by elemental analyses, conductance, IR, 1H NMR and UV spe...
