An alloy based on copper electrical conductivity and a softening temperature of the castings for applications in the electronicCopper-based alloy, in particular for applications in electronics, for the manufacture of the supports of the components, characterized in that it contains from 0,1 to 1% ...
In addition to the room-temperature mechanical properties, the 1.0LaB6-Cu also shows improved thermal stability at elevated temperatures. Cu and its alloys are often used in elevated temperature environments (heating due to electrical currents, or heat management applications)44. After exposure to ele...
Compared with Al2O3, AlN is more expensive, but it has better mechanical and thermal performance (thermal conductivity larger than 150 W/m·K) and therefore has become popular in high-temperature applications [5]. The bottom copper layer is usually not patterned and is soldered to the ...
Conductivity: Copper is nearly as conductive as silver – the most conductive metal – but comes at a fraction of the cost. Ductility: Copper can easily be shaped into wire, which is important for most electrical applications. It’s also important to note that temperature does not affect copp...
A bright appearance of the deposits usually indicates better mechanical and electrical properties. The coating is composed of Cu, and other possible ingredients, such as B, N, are invisible. In addition, copper plating on modified fabric has good adherence stability and high electrical conductivity ...
The electrical conductivity test was performed using a four point probe resistivity tester at room temperature. The specimen has a dimension of 1 × 1 × 52 mm3with longitudinal direction parallel to the swaging direction. The specimens were strictly cut from the central positions of al...

The electroreduction of CO2was conducted in CO2-saturated 0.5 M KHCO3solution without or with different amounts of EDTMPA additives at room temperature and atmospheric pressure. The electrolyte was purged with CO2for at least 30 min to remove residual air in the reservoir. ...
A1H NMR spectrum of [(hfac)Cu]2(DMDVS) is shown inFIG. 1, left side, at room temperature. The resonance of bonded vinyl protons shifts upfield significantly (about 1-3 ppm) compared to those of free ligand DMDVS, shown in the right hand portion of the spectrum of FIG.1. ...
