• Synthesis of Nanomaterials by High Energy Ball Milling

    In particular mechanical attributed contamination by the milling tools (Fe or WC) as well as ambient gas (trace impurities such as O 2 N 2 in rare gases) can be problems for high-energy ball milling. However using optimized milling speed and milling time may effectively reduce the contamination.
