The Fe 2+-substituted LiFe x Mn 1-x PO 4 /C (x = 0.2, 0.5, and 0.8) samples were prepared using the high energy ball mill-assisted soft template method as described earlier. Figure 3A shows the XRD of the LiFe x Mn 1-x PO 4 /C (x = 0.2, 0.5, and 0.8) samples. All the Bragg peaks belong to the Pmnb space group (JCPDS Card No. 33-0803).

Focused ion beam milling: A method of site-specific sample …

milling to extract TEM sections from a carbonate-rich alter-ation veinlet within the Lafayette Martian meteorite were only partially successful (Vicenzi and Heaney 1999). Whereas the silicate host (olivine Fa 67) within the meteorite remained in-tact, Ca-rich siderite intergrowths were largely amorphized.

Machining - Wikipedia

Machining is a process in which a material (often metal) is cut to a desired final shape and size by a controlled material-removal process. The processes that have this common theme are collectively called subtractive manufacturing, in contrast to additive manufacturing, which uses controlled addition of material.Exactly what the "controlled" part of the definition implies can vary, but it ...
