A composition is prepared by mixing at least one aluminum halide (preferably AlCl 3 ), at least one copper(II) salt (preferably CuCl 2 ), calcium aluminate and at least one alcohol (preferably ethanol), shaping the mixture, and drying the shaped particles. The thus-obtained catalyst ...
A process for the preparation of water gas shift catalyst is described. The process includes mixing a copper salt and a zinc salt with an aluminum component in a solution, precipitating a precipitate from the solution, drying an forming the precipitate i
The thermal pad may contain copper. In one embodiment, there is an individual thermal pad beneath each LED. In another embodiment, one or more LEDs may share one thermal pad. The LED is thermally coupled to the thermal pad 730 and then the thermal pad 730 is thermally coupled to the ...

ALUMINUM-copper alloysIn this study, ultrasonic vibration (USV) was evaluated in preparation of Al–8wt.%Cu alloys at a lab-scale. Moreover, the role of Ti–6Al–4V sonotrode erosion and its contribution in grain refining were analyzed. Based on the experimental conditions/paramete...
Said body may be produced by a method in which (i) an oxidic material is prepared, comprising copper oxide, aluminum oxide, and at least one oxide of lanthanum, tungsten, molybdenum, titanium, or zirconium, followed by (ii) addition of powdered metallic copper, copper platelets, powdered ...
