Cryogenic sample grinding for copper, lead and
2010-8-11 A simple method is proposed for copper, lead and manganese determination in deciduous teeth by graphite furnace atomic absorption spectrometry (GFAAS) using slurry sampling introduction and cryogenic sample preparation. Teeth samples were ground in a cryogenic mill in two steps: pre-cooling (5 min) and cryogenic grinding (2 min) in liquid nitrogen.

Mechanochemical synthesis of copper manganese
2015-4-1 A series of copper manganese oxide catalysts have been prepared by mechanochemical grinding of carbonate precursors and tested for the low temperature oxidation of CO. It is shown that a 72 h grind time and heat treatment under oxygen is necessary to form active CuMn 2 O 4 for the conversion of CO to CO 2 at room temperature. Energy dispersive X-ray analysis mapping indicated that the degree of mixing was improved at longer grinding
