Nanophase, definition

The hydrogen storage capacities for disordered graphites, nanographites, and activated carbons are collected in Table 4.1. One can conclude that activated carbons are better storage materials than CNTs and most experimentally investigated carbon nanophases (like GNFs). Yet, if one applies a broader definition of nanomaterials, the activated carbon phases are, indeed, the disordered and nanostructured carbons. 

Siegel has formed a company called Nanophase Technologies Corporation to commercialize his work. The opportunities look bright for nanocrystalline materials. Sometimes smaller is definitely better. ... 

We want to outline here the definition of solubility diagram and separate it from the definition of phase diagram which is now transformed into the nanophase diagram. Strictly speaking, the phase diagram is split, so the definitions should be split as well [81]. 

It foUows that, when one deals with the phase diagram, one must determine and plot the solubility curves in one T-C nanophase diagram (in the authors definitions) as well as the final equilibrium compositions, the boundaries of the phases of the already transformed system found by the transition criterion... 

The nonequivalence of the rates of photosensitized reactions in heterogeneous nanophases of glassy polymers is proved in experiments with naphthalene phosphorescence decay. For example, it is shown [13] that in aerated PMMA films fluorescence of singlet-excited naphthalene molecules N can be decayed by tinuvin P, but this does not affect the rate of naphthalene dissociation. The latter is consumed in the process, the rate of which is not defined by the concentration of particles responsible for fluorescence. Under such conditions, according to definition by the authors [13], primary chemical acts are inevitable. However, in the absence of oxygen tinuvin P slows the photochemical process down in accordance with a decrease of singlet-excited naphthalene molecule concentration.
