    Morphological properties.The image of the surface and morphological structure of the sample indicates that the realgar nanopowder obtained was condensed and highly porous and was comprised of 20 nm spherical particles larger particles observed in the surface of the image were formed as a result of the aggregation of the smaller particles, which manifested as irregular spherical shapes.

  • Mechano Chemical Synthesis Of Ammonia And Acetic

    Abstracta mechano-chemical reaction formed by a simple high-energy ball milling was applied to simulate the synthesis of ammonia and organic precursors from common inorganic materials that occurred on early earth.By milling for 0.564 h at centrifugal accelerations of 20150 g, ammonia and acetic acid were produced from inorganic materials, such as iron nitride, nitrate, carbide, and.

  • Mechanochemical Routes To Functionalized Graphene

    Dry ballmilling of graphite in a planetary mill under gas pressure is a scalable and environmentally benign onestep process, which requires neither hazardous solvents nor tedious separate functionalization and purification steps.Gas type, pressure, and milling duration govern average particle size, shape, and functionalization.
