Abstract Hydrogen could be considered a synthetic secondary power carrier fuel in the years to come, subsequent to the fossil fuels economy. Thus the concept 'hydrogen economy' shall be defined, and it will also have a great influence in the future years.The field of power generation (producing electric power), transports, (electric cars), chemistry (hydrogen is a major raw material) are ...

These surface r e x tioris usually lead to the deposition of a t h i n layer of the reaction products. The major advantages of these plasma processes over the chemical ones are that they affect only the material surfaces and their great intensity requires only a very short time to achieve a significant effect. thus conduciveto continuous processes.

The efficiency of the dense medium separation process is known to depend on the rheology and stability of the medium. In particular, the medium should exhibit a low viscosity and a high settling stability. Despite this knowledge, little information existed on these medium properties. The lack of information stems partially from the difficulties associated with measuring the rheological ...
