    Wet milling of wheat is the process of separating flour into its components, primarily starch and gluten, using water in the process. This can easily be illustrated in a household kitchen. Take some flour and add enough water to form a dough ball and then knead the ball for a few minutes to allow the gluten to form.

  • Mechanical Alloying A Novel Technique To Synthesize

    Mechanical alloying is a solid-state powder processing technique that involves repeated cold welding, fracturing, and rewelding of powder particles in a high-energy ball mill. Originally developed about 50 years ago to produce oxide-dispersion-strengthened Ni- and Fe-based superalloys for aerospace and high temperature applications, it is now recognized as an important technique to synthesize ...
