This is why Nanotechnology is the most important key player (as a technology that can be applied to other fields of technologies) in the whole business. My use of wiki here is used for a direct description to give headway to viable sources of information. Nucleation is the first step in the formation of either a new thermodynamic phase or a new structure via self-assembly or self-organisation. Nucleation is typically defined to be the process that determines how long we have to wait before the new phase or self-organised structure, appears. Nucleation is often found to be very sensitive to impurities in the system. Because of this, it is often important to distinguish between heterogenous nucleation and homogeneous nucleation. Heterogeneous nucleation occurs at nucleation sites on surfaces in the system. Homogenous nucleation occurs away from a surface. en.wikipedia.org/wiki/Nucleation -------------------- The reason I post a google link to numerous google links, is when there are too many links too choose from. few examples by title, for heterogeneous: Selective Heterogeneous Nucleation and Growth of Size-Controlled Metal Nanoparticles on Carbon Nanotubes in Solution Heterogeneous Seeded Growth: A Potentially General Synthesis of Monodisperse Metallic Nanoparticles Heterogeneous nucleation of/on nanoparticles: a density functional study using the phase-field crystal model Heterogeneous Nucleation on Charged Nanoparticles heterogeneous nucleation of synthetic nanoparticles: https://google/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=heterogeneous%20nucleation%20of%20synthetic%20nanoparticles scholar.google/scholar?q=Heterogeneous+nucleation+of+synthetic+nanoparticles&hl=en&as_sdt=0&as_vis=1&oi=scholart&sa=X&ei=km6oVPaGDseOyAT784KgAw&ved=0CBsQgQMwAA - Now, lets switch over to homogeneous (by title): Shape and Aggregation Control of Nanoparticles: Not Shaken, Not Stirred Binary homogeneous nucleation and growth of water–sulfuric acid nanoparticles using a TEMOM model Shape Control of Colloidal Metal Nanocrystals - Chemistry The kinetics of homogeneous nucleation of silver nanoparticles stabilized by polymers Homogeneous nucleation of synthetic nanoparticles: https://google/search?q=Homogeneous+nucleation+of+synthetic+nanoparticles&hl=en&gws_rd=ssl scholar.google/scholar?q=Homogeneous+nucleation+of+synthetic+nanoparticles&hl=en&as_sdt=0&as_vis=1&oi=scholart&sa=X&ei=InCoVNewIpOHyATZmoCgAw&ved=0CB0QgQMwAA -- Clouds form when wet air cools (often because the air is rising) and many small water droplets nucleate from the supersaturated air. The amount of water vapor that air can carry decreases with lower temperatures. The excess vapor begins to nucleate and form small water droplets which form a cloud. Nucleation of the droplets of liquid water is heterogeneous, occurring on particles referred to as cloud condensation nuclei. Cloud seeding is the process of adding artificial condensation nuclei to quicken the formation of clouds.

In particular, new methods employing the latest techniques in molecular self-assembly and supramolecular control for synthesizing and assembling nano-structured energetic materials were studied. The synthetic efforts of the program were guided by state-of-the-art theoretical calculations and advanced dynamic performance testing methodologies that also operate on all length scales. To accomplish these objectives, the program made use of a combination of novel nanotechnology fabrication techniques, state-of-the-art theoretical modeling techniques that can interrogate events occurring from the atomistic/molecular scale through the mesoscale to the macroscale, and experimental diagnostic techniques that can capture the reactive dynamics at femtosecond timescales to those that evaluate overall combustion performance. dtic.mil/dtic/tr/fulltext/u2/a544673.pdf ------ Please note femtosecond timescales. It is now proven, that the Teramobile femtosecond laser, can modify cirrus-clouds with plasma-evaporate ice crystals. They have already experimented with this laser system and proven its capabilities, so...sorry there trolls. cirrus-clouds = natural cirrus and chemtrail-cirrus ___________________________
