Stylus-based surface profiling is a standard technique for accurate, repeatable surface shape, topography and step height measurement in applications ranging from semiconductor R&D to solar cell QC.

从中药中提取分离化合物，第一步需要将中药材中的成分用有机溶剂提取出来，包括常规的有机溶剂浸泡，超声提取，超临界提取和加速溶剂萃取（Aseeker-600型加速溶剂萃取仪）等，得到一份总提物。

Using Bruker’s Hysitron PI 88 SEM PicoIndenter equipped with tilt and rotation stages in conjunction with the QUANTAX EBSD system enables a more robust characterization of metallic materials by combining high resolution phase and grain orientation mapping capabilities with targeted nanomechanical property measurements. This combination could also be used to extend the scope of research related to other advanced textured, anisotropic, or multi-phase materials.
