Figure 3From: Determination of the volume-specific surface area by using transmission electron tomography for characterization and definition of nanomaterialsElectron tomographic analyses of silica NM. The micrographs, taken at 0°, show one (Figure 3A) and two aggregates (Figure 3C) consisting of multiple primary subunits of NM-200 and NM-203, respectively. Figure 3B and Figure 3D show the corresponding ET reconstructions. Bars: 200 nm.Back to article page
