SEM Analysis with EDS Capabilities. Scanning Electron Microscopy (SEM) is a test process that scans a sample with an electron beam to produce a magnified image for analysis. The method is also known as SEM analysis and SEM microscopy, and is used very effectively in microanalysis and failure analysis of solid inorganic materials.
Converged ion beam polishing system using radio frequency based gridded ion source and applications thereof
Converged ion beam polishing system using radio frequency based gridded ion source and applications thereof The present invention discloses a dual-source broad ion beam polishing system designed for high-precision surface and cross-section milling It features an ion milling chamber (01) and load lock chamber (02) connected via a transfer arm (03). Two inductively coupled plasma ion sources with gridded extraction are mounted on flanges (04): an EBSD ion source (05a) for flat milling and a cross-section ion source (05b) for cross-sectional polishing, each with dedicated specimen holders (09a, 09b) and adjustable ion incidence. The cross-section source includes a conical aperture (12) to produce a 3 mm collimated beam for high-resolution thinning. Dielectric plasma chambers (06), inductive coils (07), and focusing grids (08) ensure stable ion generation. Shutters (11a, 11b) serve as Faraday devices. Real-time monitoring is provided by an integrated CMOS camera. The system enables efficient, artifact-free sample preparation for EBSD and SEM analysis across fields like metallurgy, semiconductors, materials science, and geology.

The application discloses a monoclinic phase BiVO4 micropipe prepared by a microwave radiation method and a preparation method thereof. Pure Bi(NO3)3.5H2O and NH4VO3 are used as reaction raw materials, distilled water is used as a solvent, polyethylene glycol (PEG-10000) with a molecular weight of 10000 is used as a surfactant, and a monoclinic phase BiVO4 micropipe material is prepared by using a microwave radiation technology. The microwave radiation process is simple in operation, energy-saving and environment-friendly, low in energy consumption, and energy-concentrated, and is favorable for improving a reaction rate and a synthesis efficiency of the BiVO4 material. The XRD and SEM analysis results of the product fully prove that the method can obtain the BiVO4 material with regular morphology and small particle size, is favorable for increasing active sites of the BiVO4 material, and thus improves the photocatalytic performance of the BiVO4 material. The target product BiVO4 material has the abilities of catalytic degradation of pollutants, catalytic photoelectrochemical decomposition of water and energy storage, and is expected to play an important role in the field of photocatalysis.
