AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Carbon nanotubes with unique physical and mechanical properties have shown great potential for biological applications, including tissue engineering and mimicking the structure and properties of human bones. In the present work, sol-gel synthesized nanocom ...
Embrittlement by helium was investigated in a lamellar TiAl alloy under two conditions: Specimens were implanted to various amounts of helium up to 762 appm at temperatures from 630 °C to 1000 °C and some of them subsequently creep-tested at the same tempe ...
We study in this thesis the structural origin of defect insensitive light emission in indium containing group-III nitride ternary alloys grown on sapphire, which are the active materials for the commercially available high brightness blue diodes. These str ...
This device is for holding samples during their preparation prior to imaging in the electron microscope. The design means it can be transferred between the light and electron microscopes as well as trimming devices used to prepare the final sample. It can ...
The ability to reshape nanopores and observe their shrinkage under an electron microscope is a powerful and novel technique. It increases the sensitivity of the resistive pulse sensing and enables to detect very short and small molecules. However, this has ...
Cryo electron tomography provides nanometer-scale information on biological matter preserved in a close-to native state. The resolution of tomograms and structures resolved by sub-tomogram averaging is typically limited by the contrast transfer function of ...
The oxidation of nickel particles was studied in situ in an environmental transmission electron microscope in 3.2 mbar of O-2 between ambient temperature and 600 degrees C. Several different transmission electron microscopy imaging techniques, electron dif ...
Although the analogies between the electron energy loss spectra and X-ray absorption spectra were recognized long ago, the possibility to observe the magnetic circular dichroism in the electron microscope was demonstrated only recently. This technique comb ...
Cryo-electron microscopy is a form of transmission electron microscopy that has been used to determine the 3D structure of biological specimens in the hydrated state and with high resolution. We report the development of 4D cryo-electron microscopy by inte ...
The ability to reshape nanopores and observe their shrinkage under an electron microscope is a powerful and novel technique14,17. It increases the sensitivity of the resistive pulse sensing and enables to detect very short and small molecules12,31. However ...
