ABSTRACT
It is demonstrated that formation of MgO nanoparticles during a Mg particle combustion occurs in the vapor adsorption regime and the particle coagulation and coalescence do not play any significant role in the process in question. Analysis of the particle size distributions shows that the rate of the nanoparticle condensation growth strongly depends on the actual particle size. The revealed dependence of the growth rate upon the size is consistent with the exponential law recently predicted. This finding can shed light on the long-standing general problem of gas-phase nanotechnology—the origin of lognormal size distribution behavior of generated nanoparticles.

    An expression is verified to allow for the contribution of self-adsorption in the Young equation for the interface between a polycrystalline metal and its own melt using only two properties, the heat of fusion and the gram-atomic volume. The adequacy of this relation is established for precious...

    The adsorption of a dense fluid of hard spheres on a lattice of attractive sites disposed on a planar interface is studied by numerical simulations. These show that the adsorbed spheres associate into clusters and that the adsorption occurs continuously, apparently without order–disorder...
