TLDR
In this article, 3D transmission electron microscopy (3D-TEM) combined with electron tomography was used to visualize and evaluate structural characteristics in 3D space, such as the size and volume of in situ silica generated in the NR matrix by the sol-gel reaction of tetraethoxysilane, at nanometer scale resolution.Abstract:
Summary: Three dimensional (3D) nanostructures of particulate silicas in natural rubber (NR) were observed for the first time by use of 3D transmission electron microscopy (3D-TEM) combined with electron tomography The method enabled us to visualize and evaluate structural characteristics in 3D space, such as the size and the volume of in situ silica generated in the NR matrix by the sol-gel reaction of tetraethoxysilane, at nanometer scale resolution

Three-dimensional nanoscale organization of bulk heterojunction polymer solar cells.
TL;DR: After annealing treatment, genuine 3D nanoscale networks are formed with high crystalline order and favorable concentration gradients of both P3HT and PCBM through the thickness of the photoactive layer, which accounts for a considerable increase of the power conversion efficiency in corresponding solar cell devices.

Visualisation of carbon black networks in rubbery matrix by skeletonisation of 3D-TEM image
TL;DR: In this paper, the first visualization of nanofiller networking due to association of carbon black in natural rubber is achieved by a transmission electron microscopy combined with computerised tomography (3D-TEM), and the resulted skeleton displays the characteristics of the filler network, which has long been assumed on the percolation behaviour in electron conductivity and on the mechanical behaviours of filled rubbers.
