In thermites using aluminum metal as the fuel, the passivation of the metal surface with oxide must be taken into account. For micrometer sized particles of aluminum, the oxide passivation layer is negligible, but on the nano-scale this passivation layer of alumina begins to account for a significant mass portion of the nanoparticles. In addition, the precise nature of the oxide layer is not the same for all manufacturers of aluminum nanoparticles, so the researcher must use TEM to measure oxide thickness to allow calculation of active aluminum content before stoichiometric calculations are carried out for the mixing of thermites. Table 13.3 shows details of some of the percentages of aluminum in aluminum nanoparticles and shows just how significant and inconsistent the oxide layer can be. [Pg.265]

As the gas is cooled, it becomes supersaturated, leading to the nucleation of particles. This nucleation is a result of molecules colliding and agglomerating until a critical nucleus size is reached and a panicle is formed. As these particles move down, the supersaturated gas molecules conden.se on the particles causing them to grow in size and then to flocculate. In the development on the CD-ROM. w c will model the formation and growth of aluminum nanoparticles in an, AFPR. [Pg.233]

Ma et al. [5] first demonstrated that resistive switching could be achieved by depositing a layer of aluminum nanoparticles between two organic layers. The depositions of the nanoparticles and the organic layer can be controlled independently and hence the distribution of nanoparticles can be very well controlled in these devices. [Pg.449]

The effect of the aluminum oxide layer is also known to reduce the propagation of thermite reactions since alumina is an effective absorber of thermal energy. A study by Weismiller et al. of a 49 % active aluminum nanopowder in a thermite with copper oxide supports the idea that too much oxide can actually reduce thermite performance. Table 13.4 shows Weismiller s data which indicates the negative effect of a thick oxide layer on aluminum nanoparticles. [Pg.212]

Figure 8.3c shows Raman spectra of a 1-nm-thick adenine film deposited on a 140-nm-wide aluminum nanoparticle array and on fused silica [23]. The Raman scattering intensity of adenine on aluminum nanoparticles was significantly increased compared with that on fused silica. The excitation laser wavelength was 257 nm, which matches the observed quadrupolar plasmon resonance in a 140-nm-diameter aluminum nanoparticle. The adenine sample has absorption at 270 nm (see also the inset in Fig. 8.6b). The excitation laser wavelength was in the absorption band of adenine.
