TL;DR: The experimental demonstration of a general electron tomography method that achieves atomic-scale resolution without initial assumptions about the sample structure is reported, and it is anticipated that this general method can be applied not only to determine the 3D structure of nanomaterials at atomic- scale resolution, but also to improve the spatial resolution and image quality in other tomography fields.

TL;DR: 3D imaging of dislocations in materials at atomic resolution by electron tomography is reported, and nearly all the atoms in a multiply twinned platinum nanoparticle are observed by applying 3D Fourier filtering together with equal-slope tomographic reconstruction.

TL;DR: It is demonstrated that EST reconstructions with the lowest scanner flux setting of 39 mAs produce comparable image quality, resolution, and contrast relative to FBP with the 140 mAs flux setting, and a significant reduction in computation time is achieved with EST.

TL;DR: Zhu et al. as mentioned in this paper proposed a novel approach to solve the problem of particle filtering in the context of nanosystems, which can be seen as an example of the work we are investigating in this paper.

TL;DR: In this article, the 3D surface morphology and internal lattice structure revealed are consistent with a distorted icosahedral multiply-twinned particle, which can be used not only to determine the structure of nanomaterials at atomic scale resolution, but also to improve the spatial resolution and image quality in other tomography fields.
