“…Materials processing in centrifuges have two interesting motivations: first, opportunities for production of unique and improved materials that cannot be prepared under normal earth conditions or in space; second, such research improves our understanding of the influence of acceleration and thermophysical mechanisms on materials processing. Research on processing materials in high gravity has been increased in the last twenty years due to the fact that even a modest increase in acceleration gives dramatic effects on the physical properties of the materials [1]. Few examples are the improved compositional homogeneity of semiconductors [2,3]: the increased nucleation rates, growth rates, and coverage area for diamond film deposition [4,5]; the improved quality of protein and high-energy crystals [6]; the large-scale production of nanoparticles [7,8].…”
