In the transmission electron microscopy (TEM) images, the starch nanoplatelets (SNPs) are believed to aggregate as a result of hydrogen bond interactions due to the surface hydroxyl groups [13] (Fig. lA). Blocking these interactions by relatively large molecular weight molecules obviously improves the individualization of the nanoparticles. The acetylated starch and cellulose nanoparticles (SAcNPs and CelAcNPs) appeared more individualized and monodispersed than their unmodified counterparts with a size of about 50 nm (Fig. IB C). [Pg.124]

The transmission electron microscopy (TEM) images of a two-layer Tl-1223 film are shown in Fig. 7.12, which confirms the epitaxial nature of the annealed electrodeposited films. All films showed a significant amount of intergrowth, as shown by a high-resolution transmission electron microscopic (HRTEM) measurement in Figs. 7.12c and d of a representative two-layer... [Pg.221]

The reaction was so fast as to finish within 1 min, as shown by the transmission electron microscopy (TEM) images in Figure 3.3.2, for which each withdrawn sample on a copper grid was instantly quenched with liquid nitrogen and freeze-dried without melting. [Pg.209]

Microstructures of (1) PE-g-PPG polymer hybrid and (2) the blended sample of PE and PPG were observed by transmission electron microscopy (TEM) images after the preparation of press sheets of each polymer sample at 200 °C. The TEM images of the resulting polymer hybrid reveal the nanometer level microphase-separation morphology between the PE segment and the PPG segment compared with the PE/PPG blended polymer. From the result, the nanodispersion of different segments in polymer hybrids is possible, but different from the blended polymer sample (Fig. 8). [Pg.89]

The transmission electron microscopy (TEM) image of the sample is shown in Figure 3 (A). This image displays a rod-like nanocrystallite (50 nm x 350 nm). The SAED patterns of the sample were taken in different projection. One of the patterns is parallel to the ab plane as shown in Figure 3 (B). [Pg.134]

The transmission electron microscopy (TEM) images were acquired using a Phillips CM200FEG microscope operated at lOOkV. The scanning electron microscopy (SEM) photograph was obtained on a JEOL, JSM-35C microscope operated at 25kV. [Pg.235]

The advantage of this reaction lies on the creation of nitrogen, which makes an inert ambience to prevent nanoparticels from further oxidation. So it is convenient route to make metal nanoparticles. The formation of the assembled iron particles can be directly seen by transmission electron microscopy (TEM) image (in Figure la), the average size of assembled spheres is about 210 10 nm. The X ray diffraction pattern of the products (Figure lb) revealed the formation of cubic Fe [21]. [Pg.400]
