Essentially, scrap rubber is cryogenically ground to a fine powder, then treated with a unique combination of non-hazardous, non-toxic, chemical reactants.
As De Kepper's burning-grass metaphor might suggest, this stable, chemical quilt emerges from a continuous interplay between the initial chemical reactants and their own reaction-inhibiting products, as those products diffuse into surrounding areas.
While ALD process developers are sometimes hampered by the need to find reactive saturating precursor combinations for ALD process windows that are closely matched in temperature for each element in a film stack, NLD[TM] technology uses plasma treatment steps in place of paired chemical reactants, to overcome this limitation, thus allowing for increased process latitude in the fabrication of complex dielectric films and metal alloys.
Moreover, there are some important aspects controlling the dispersion of chemical reactants such as diffusion and compatibility that should be taken into account as well (11, 12).
When another creature yanks on one of its legs or antennae, a bombardier beetle contracts muscles in glands that store chemical reactants in separate compartments.
