Iterative Bayesian denoising based on variance stabilization using Contourlet Transform with Sharp Frequency Localization: application to EFTEM images

Autor: Soumia Sid Ahmed, Zoubeida Messali, Larbi Boubchir, Ahmed Bouridane, Sergio Marco, Cédric Messaoudi

Publikováno v: BMC Biomedical Engineering, Vol 1, Iss 1, Pp 1-12 (2019)

Abstract Background Due to the presence of high noise level in tomographic series of energy filtered transmission electron microscopy (EFTEM) images, alignment and 3D reconstruction steps become so difficult. To improve the alignment process which wi

Amorphization of Graphite Flakes in Gray Cast Iron Under Tribological Load

Autor: Ruth Hinrichs, Marcos Antonio Zen Vasconcellos, Werner Österle, Claudia Prietzel

Publikováno v: Materials Research, Vol 21, Iss 4 (2018)

A gray cast iron disc, which had been submitted to a heavy duty automotive brake test, was examined with energy filtered transmission electron microscopy. A graphite flake in a convenient angular position showed the shear interaction of graphite laye

Nonparametric Denoising Methods Based on Contourlet Transform with Sharp Frequency Localization: Application to Low Exposure Time Electron Microscopy Images

Autor: Soumia Sid Ahmed, Zoubeida Messali, Abdeldjalil Ouahabi, Sylvain Trepout, Cedric Messaoudi, Sergio Marco

Publikováno v: Entropy, Vol 17, Iss 5, Pp 3461-3478 (2015)

Image denoising is a very important step in cryo-transmission electron microscopy (cryo-TEM) and the energy filtering TEM images before the 3D tomography reconstruction, as it addresses the problem of high noise in these images, that leads to a loss

Elemental mapping of labelled biological specimens at intermediate energy loss in an energy‐filtered TEM acquired using a direct detection device

Autor: Mark H. Ellisman, Steven T. Peltier, Stephen R. Adams, Xuong Nguyen-Huu, Junru Hu, Ranjan Ramachandra, Mason R. Mackey

Publikováno v: Journal of Microscopy
Journal of microscopy, vol 283, iss 2

The technique of colour EM that was recently developed enabled localisation of specific macromolecules/proteins of interest by the targeted deposition of diaminobenzidine (DAB) conjugated to lanthanide chelates. By acquiring lanthanide elemental maps

Nano-structuring, surface and bulk modification with a focused helium ion beam

Autor: Daniel Fox, Yanhui Chen, Colm C. Faulkner, Hongzhou Zhang

Publikováno v: Beilstein Journal of Nanotechnology, Vol 3, Iss 1, Pp 579-585 (2012)

We investigate the ability of a focused helium ion beam to selectively modify and mill materials. The sub nanometer probe size of the helium ion microscope used provides lateral control not previously available for helium ion irradiation experiments.
