1.详细描述样品有着怎样的形貌,由哪些微观结构组成,是什么原因造成的。

 

实例一:SEM imaging shows that the as-deposited films consist of platelets roughly 100 nm in diameters that tend to be vertically oriented and randomly distributed on the electrode surface. This morphology is consistent with that typically observed for layered double hydroxides or oxyhydroxides adopting a brucite-like structure with octahedrally coordinated metal cations hexagonally packed insheets that are separated by water and charge-balancing ions.

句式模板:SEM imaging shows that __ consist of__ roughly __ nm in diameter…This morphology is consistent with that typically observed for…

 

变型:The __ had typical diameters of ~ nm and (thin, wide) shells that were ~ _ nm thick. SEM images recorded at high magnification clearly show the (perfect) __ shape of the __, with uniform shapes and flat surfaces. (Kong, X. et .al. Science, 2004, 303, 1348-1351)

 

 

实例二:High-magnification SEM images show that the rods that compose these tubular structures are highly ordered, with the gold ends on the exterior of the structure and the polymerends all pointing toward the interior of the tubes. Rods with a 3:2 gold/polymer ratio also yield tubular structures but with ~ 29 μm diameters.

 

(Ref. Park, S. et. al. Science, 2004, 303,348-351)

 

句式模板:High-magnification SEM images show that __ that compose these __structures are __, with… __with __ also yield __ structures but with ~ nmdiameters.

 

 

实例三:The scanning electron microscopy (SEM) images of both ZnO films also showed essentially the same smooth surface morphology composing of closely packed particles with a particle size of 30?50 nm, indicating that each particle was a ZnO single crystal since this particle size was similar to the one calculated from the XRD results.

 

(Ref. Ong, B. et al. J.Am. Chem. Soc., 2007, 129, 2750–2751)

 

句式模板:The scanning electron microscopy (SEM) images of __ also showedessentially the __ morphology composing of __ with a particle size of __ nm, indicatingthat …

实例一:SEM micrographs show that particles of 1 adopt a rodlike morphology with diameters of 50?100 nm and lengths of 750 nm toseveral μm.

 

(Ref.: Taylor, K. et. al. J. Am. Chem. Soc., 2008,130, 14358-14359)

 

句式模板:SEM micrographs show that particles (of _) adopt a __morphology with diameters of __ nm and lengths of __ nm.

 

变型:The resulting (suspended particles) of __ were found to be (microsizedcubic crystals), as shown in Figure 1, with an average size of __ μm. (Ref.: Ni, Z. et al. J. Am. Chem. Soc., 2006, 128,12394–12395)

 

 

 

实例二:A high magnification SEM image of the tilted sample reveals that most nanotubes are vertically aligned. These nanotubes are about 12 nm in diameter, in line with the results reported in the literature.

 

(Ref. Tian, Z. et al. J. Am. Chem. Soc., 2003, 125,12384–12385)

 

句式模板:A high magnification SEM image of __ reveals that … These __ areabout _ nm in diameter, in line with the results reported in the literature.

 

实例三: Figure 2 shows scanning electron microscopy (SEM) images of the resulting MoS2/RGO hybrid, in which the RGO sheets were uniformly decorated with MoS2 nanoparticles.

 

(Ref.Li, Y. et al. J. Am. Chem. Soc., 2011, 133, 7296–7299)

 

句式模板:Figure 2 shows scanning electron microscopy (SEM) images of __,in which…

 

变型:SEM images under high magnification clearly show (hierarchical mesoporosity in the range of 5-40 nm.) (Ref.:Xiao, F. et al. Angew. Chem. Int. Ed.2006, 118, 3162-3165.)

 

2.SEM作为佐证来说明前面已经证实的结论

 

 

实例一:High-resolution scanning electron microscopic (SEM) images confirm that the pore structures of the carbon samples vary with the carbon precursors and the processing methods.

 

(Ref.: Liang, C. and Dai, S. J. Am.Chem. Soc., 2006, 128, 5316–5317)

 

句式模板:High-resolution scanning electron microscopic (SEM) images confirm that…
