Application

Iron is generally used as a catalyst for wide variety of organic transformations. It has been used for the synthesis of magnetic polydimethylsiloxane (PDMS) for automated microcontact printing of biomolecules.
Iron can also be used:
  • For the removal of arsenate from water.
  • To synthesize Fe(III) iodide catalyst for thioglycosylation of peracetylated saccharides.
  • As a catalyst for the graphitization for microscale radiocarbon analysis of small samples.
  • For the removal of nitroaromatic pesticides by reduction.

Self-Propagating Reactions Induced by Mechanical Alloying

Mechanical alloying is a “brute force” method of affecting alloying and chemical reactions. The mixture of reactant powders and several balls are placed in the milling jar of a high-energy ball mill, for example, a shaker mill or a planetary mill.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
