摘要:
The reactor is used for producing nano-particles of metal from volatile moieties in flow through mode. The reactor comprises at least a first feeder and a second feeder on one end of the vessel. The first feeder feeds the moiety in the form of an educt fluid into the reactor. This fluid is a mixture of metal moieties and a bearer fluid, entering the reactor in a vaporized state, in which the bearer fluid is used as a carrier gas. The second feeder is used as a radiator means to heat up the educt fluid within the reactor. By providing the heating fluid through the second feeder control over some environmental conditions like ambient temperature within the reactor is achieved and dissociation of the metal moieties under such controlled conditions leads to quantitative production of selected nano-particle morphologies.

A method of forming impressions in a flexible graphite sheet is provided. More particularly, the inventive method involves contacting a flexible graphite sheet with an forming element capable of oscillating against the flexible graphite sheet, whereby the oscillations in the element are such that a plurality of impressions are formed in the flexible graphite sheet.
