3D Analysis of Helium-3 Nanobubbles in Palladium Aged under Tritium by Electron Tomography

نویسندگان

چکیده

A 3D analysis at the nanoscale has been used to characterize helium-3 nanobubbles in palladium powders aged several years under tritium assess their structural characteristics and spatial distribution. These are formed by radioactive decay exhibit diameters centered around 2.5 nm. Scanning transmission electron microscopy (STEM) acquire tomographic series on typical zones of macroscopic specimen containing helium nanobubbles. Electron tomography data treatments have achieved, allowing For first time, interdistances between bubbles determined with a mean value 8 10 The swelling material varies 18%, agreement measurements modeling.

Atomic masses of tritium and helium-3.

By measuring the cyclotron frequency ratios of (3)He(+) to HD(+) and T(+) to HD(+), and using HD(+) as a mass reference, we obtain new atomic masses for (3)He and T. Our results are M[(3)He]=3.016 029 322 43(19)  u and M[T]=3.016 049 281 78(19)  u, where the uncertainty includes an uncertainty of 0.12 nu in the mass reference. Allowing for cancellation of common systematic errors, we find the Q...

Tritium Production from Palladium Alloys

A number of palladium alloys have been loaded with deuterium or hydrogen under low energy plasma bombardment in a system that allows the continuous measurement of tritium. Long run times (up to 200 h) result in an integration of the tritium and this, coupled with the high intrinsic sensitivity of the system (~ 0.1nCi/l), enables the significance of the tritium measurement to be many sigma (>10)...

Status And Trends In 3D Nanodevices: Inspection By Electron Tomography

The reduction of the size of modern semiconductor devices has lead to the requirement of characterisation techniques with nanometer resolution, and more recently these requirements have been extended to all three dimensions. Most classical characterisation methods provide only 2-dimensional projections and are therefore unable to reproduce the complex structure of 3D nanoelectronic devices. To ...

3D structure of eukaryotic flagella/cilia by cryo-electron tomography

Flagella/cilia are motile organelles with more than 400 proteins. To understand the mechanism of such complex systems, we need methods to describe molecular arrange-ments and conformations three-dimensionally in vivo. Cryo-electron tomography enabled us such a 3D structural analysis. Our group has been working on 3D structure of flagella/cilia using this method and revealed highly ordered and b...
