Stop Flow Lithography Synthesis and Characterization of Structured Microparticles

Figure 7

SEM micrographs of single via Al₂O₃ microparticles with a circular cross section (a). (b) and (c) are successively higher magnification images to reveal the microstructural features of (a). (d) TEM of the Al₂O₃ nanoparticles in suspension as received. Scale bars: (a) = 50 m, (b) = 10 m, (c) = 100 nm, and (d) = 100 nm.
