Kim et al. [119] synthesized a mixture of Mg(AlH )2 and NaCl after 1 h of milling in a SPEX 8000 ball mill. DSC test was carried out only up to slightly over 300°C and showed the first exothermic peak at the range of 115-150°C and the second endothermic peak at the range of 240-290°C. They concluded that the first exothermic reaction corresponds to the decomposition of Mg(AlH )2 into MgH, Al and and the second endothermic peak to the decomposition of MgH. Apparently,... 

Root powdering and demineralization. Sixty-five frozen and pulp-free tooth roots were ground in a Waring blender and powdered under liquid nitrogen in a freezer mill (Spex, Edison NJ, USA). The sieved powder (< 450 pm) was demineralized in dialysis bags in 0.5 M EDTA, pH 7.4, at 4°C with regular replacement of the solution. Demineralization was continued until no further calcium release could be detected by atomic absorption spectrometry.

In the present study, 12 g from each sherd was collected. Glazes and other surfaces were mechanically removed to minimize contamination from glaze and other external compounds. Following this process, specimens were powdered and homogenized in a Spex Mixer (Mod. 8000) tungsten carbide cell mill for 12 minutes. Powdered specimens were transferred to clean polyethylene vials for transportation to the laboratory.
