Self-organized growth of nanostructure arrays on strain-relief patterns
Article Abstract:
A self-organized growth method can be used to create almost monodispersed, equally spaced nanostructures through self-organization on substrates with a period strain-relief pattern. The strain-relief patterns are created spontaneously when a monolayer or two of one material is deposited on a substrate with a dissimilar lattice constant. The feasibility of this method has been demonstrated with Fe islands on the second monolayer of Cu on a Pt(111) substrate and with Ag nucleation on 2 ML of Ag on Pt(111). This approach may be useful for the growth of quantum arrays,

Ab initio determination of solid-state nanostructure
Article Abstract:
A study was conducted to demonstrate that ab initio structure solution of the nanostructured materials is feasible using diffraction data in combination with distance geometry methods. A genetic algorithm called La Liga was developed for solving the unassigned distance geometry problem which grows large clusters by adding atoms to a population of high quality subclusters which incorporates a strategy for backtracking and updating populations of high quality clusters at each size.

Equilibrium cluster formation in concentrated protein solutions and colloids
Article Abstract:
The study reports small-angle scattering and confocal microscopy investigations of two-model system that is protein solutions and colloid-polymer mixtures. It is demonstrated that in both systems, a combination of short-range attraction and long-range repulsion results in the formation of small equilibrium clusters.
