The Origin of High Thermal Conductivity and Ultralow Thermal Expansion in Copper-Graphite Composites We developed a nanocomposite with highly aligned graphite platelets in a copper matrix. Spark plasma sintering ensured an excellent copper-graphite interfa... I Firkowska,A Boden,B Boerner,... - 《...
The electrical conductivities of the composite wires were found to be substantially lower than that of pure copper and essentially equal to the conductivity contribution of the outer copper sheath alone.doi:10.1016/0378-4363(80)90292-2S.C. Singhal...
1a), where the electrolyte accessibility is limited, and the bottom of the strip is copper current collector, in contact with the separator. Thus, the Li+ ions mainly intercalate from the lateral surfaces toward deeper region of the graphite electrode (Fig. 1c, d), and accordingly the ...
The P3HT/graphene composite also works as an oxidation-resistant and conductive film for a copper substrate, which is due to the high gas-barrier property of graphene. Graphene is one of the most interesting nanomaterials owing to its unique properties, such as high electri- cal conductivity, ...
摘要: A copper-zinc alloy powder of which zinc content is from 10 to 50 wt % and of which mean particle diameter is from 15 μm or under is added to a Pb-less brush body comprising graphite, copper and a metal sulfide solid lubricant of a copper-graphite brush....
Unlike graphite mines, base-metal mines producing metals like copper, nickel or cobalt will achieve a concentrate product of similar concentration, and the product value is directly linked to the metal mass within the concentrate. Deleterious elements (like arsenic) found in the concentrate will...
The electrical connection was provided through a wire of copper joined to the end of the tube. The surface modification of the electrode was done by immobilization 10 μL SLS surfactant on the carbon nanotube and pencil graphite composite paste electrode. 3. Result and Interpretations 3.1. FE-...

The mixture of SNGA, NG and binder was deposited on copper foil (1 mg cm−2) to prepare the electrodes (label: SNGA/NG). Two reference electrodes were prepared by mixing i) nanographite and sodium alginate binder (weight ratio 90:10) labeled as NG and ii) silicon, nanographite...
