Scanning electron microscope, resolving

Detailed transmission and scanning electron microscopic studies of shortly polymerized Si02-supported metallocene catalysts facilitated the time-resolved representation of the morphology of the various polymerization stages from the start of the reaction until the maximum activity was reached.

Identifying unknown natural materials . Mineral identification (petrology) may be performed by a combination of microscopy, X-ray diffraction and chemical analyses. Electron-probe microanalysis (EPMA) is particularly valuable in mineral identification as the technique combines spatially resolved quantitative determination of major elements with the imaging capabilities of the scanning electron microscope. 

Carbon black was an oft-examined substance during the evolution of the transmission electron microscope. It was a tour-de-force to resolve the graphitic planes in carbon black [23]. With the scanning electron microscope (SEM), more fidly dimensional views became available. In recent years, with the advent of the atomic force microscope (AFM) there have been attempts to correlate fine-scale microstructure with electrical conductivity. 

CL spectra were collected in a field-emission gun scanning electron microscope (FEG-SEM, Hitachi SE-4300) equipped with a CL device. The CL device consisted of an ellipsoidal mirror and a bundle of optical fibers to collect and to transmit the CL emission into a spectrally resolved monochromator (Jobin-Yvon/Horiba Triax 320,). A 150 gr/mm grating was used throughout the...
