Originally developed for mineral processing, mechanical treatment by ball milling is an extremely versatile technique for the degradation of toxic compounds. Reactive milling can rapidly destroy organic compounds without producing hazardous wastes. Complete breakdown of the organic molecules is achieved after relatively short milling times.
There are so many fabric dyeing techniques that produce gorgeous and diverse results. Today, I'll show you 8 different fabric dying methods with video tutorials. All of these techniques are demonstrated using Rit Dye, which is an all-purpose dye, but you can also use other types of dye like fiber reactive dyes to get the same results.
However, the novel reactive milling synthesis technique presented in this study is used to complete the nitride reaction at room temperature in a relatively short amount of time. The focus of this study is to determine the effects of the addition of dysprosium metal (as a surrogate for americium) to the uranium reactive ball milling process.

The Reactive (dry-) Milling technique  is still not widely used, even though mechanical alloying [2-4] has a long tradition and inorganic or more recently organic chemical syntheses are known to proceed to completion without producing wastes .
Milling with reactive ions is a chemical etching technique. To gain time, ion milling is often done with beams of higher energy and/or with higher current densities compared to sputter cleaning. Typically a distinction is made between focused ion beam (FIB) milling and broad ion beam (BIB) milling.
Therefore, reactive milling can be an alternative technique to produce oxides from metals. Since ball milling is a violent technique involving damaging the material, we may expect that resulting oxides would have a nanocrystalline structure.
