The Research Center on Nanotechnology Applied to Engineering (CNIS), Sapienza University of Rome is pleased to announce that the video, 'Phase Segmentation in Superjunction MOSFET using FIB-SEM tomography and 3D EDX,' has been awarded the 1st prize at the esteemed International Symposium for Testing and Failure Analysis - ISTFA 2023 Video Contest. The recognition highlights the depth and significance of the research paper presented at the conference by Dr. Flavio Cognigni, titled ‘A Multiscale and Multimodal Correlative Microscopy Workflow to Characterize Copper Segregations Identified in Epitaxial Layer of Power MOSFETs.’
This collaborative effort was enriched by the expertise and collaboration of Carl Zeiss Microscopy, Oberkochen, and STMicroelectronics, Catania. The invaluable contributions of these partners played a crucial role in bringing this project to fruition and achieving such great recognition. 

The Damascus Steel

The lost secret of the Damascus steel, the strongest material of antiquity

In Europe, the first to learn about it were the Crusaders: steel was light and strong.
The formula of its production was secret. And it was precisely this secrecy that condemned it to oblivion.

Is it possible to " un-invent" something? The answer, perhaps, is yes. The best example is precisely the Damascus steel, the legendary material used by numerous knights of the past, including the Crusaders, whose formula is still unknown, lost as a secret in the past. Many, in recent years, have tried to reproduce it. Some are convinced they have succeeded, but not everyone agrees.

X-Ray Microscopy: A Non-Destructive Multi-Scale Imaging to Study the Inner Workings of Batteries

acciaio damascoThe leading scientific journal "ChemElectroChem" dedicates the cover of its n. 7 issue to a research entitled "X-Ray Microscopy: A Non-Destructive Multi-Scale Imaging to Study the Inner Workings of Batteries," carried out as part of the iENTRANCE project, at the new CNIS laboratories in Sapienza. Authors: Dr. Flavio Cognigni, Professor Mauro Pasquali, Dr. Francesca Anna Scaramuzzo, and Professor Marco Rossi of ICI-SBAI.

"X-ray microscopy (XRM) is a non-destructive characterization technique that provides quantitative information regarding the morphology/composition of the specimen and allows to perform multiscale and multimodal 2D/3D experiments exploiting the radiation-matter interactions. XRM is particularly suitable to afford in situ images of inner parts of a battery and for the early diagnosis of its degradation in a non-invasive way.
