Designs for a quantum electron microscope [PDF]

Ultramicroscopy, 2016
One of the astounding consequences of quantum mechanics is that it allows the detection of a target using an incident probe, with only a low probability of interaction of the probe and the target. This 'quantum weirdness' could be applied in the field of electron microscopy to generate images of beam-sensitive specimens with substantially reduced ...

Spatially resolved quantum nano-optics of single photons using an electron microscope [PDF]

Physical Review Letters, 2013
We report on the experimental demonstration of single photon state generation and characterization in an electron microscope. In this aim we have used low intensity relativistic (energy between 60kV and 100 keV) electrons beams focused in a ca 1 nm probe

Attosecond metrology in a continuous-beam transmission electron microscope

Science Advances, 2020
Electron microscopy is advanced to attosecond resolution by modulating the beam with the field cycles of a continuous-wave laser. Electron microscopy can visualize the structure of complex materials with atomic and subatomic resolution, but ...

Single atom manipulation and control in a scanning transmission electron microscope [PDF]

, 2017
We demonstrate that the sub-atomically focused beam of a scanning transmission electron microscope (STEM) can be used to controllably manipulate individual dopant atoms in a 2D graphene lattice.

Isotope analysis in the transmission electron microscope [PDF]

Nature Communications, 2016
The Ångström-sized probe of the scanning transmission electron microscope can visualize and collect spectra from single atoms. This can unambiguously resolve the chemical structure of materials, but not their isotopic composition.

Multicolour correlative imaging using phosphor probes [PDF]

, 2015
Correlative light and electron microscopy exploits the advantages of optical methods, such as multicolour probes and their use in hydrated live biological samples, to locate functional units, which are then correlated with structural details that can be ...

The Impact of Multiple Autoclave Cycles on the Surface Roughness of Thermally Treated Nickel-Titanium Endodontic Files

Advances in Materials Science and Engineering, 2022
In this study, we evaluate the surface roughness (SR) of three thermally treated nickel-titanium rotary instruments (i.e., TruNatomy [TN], ProTaper Gold [PTG], and EdgeTaper Platinum [ETP]) after impact testing with multiple autoclave sterilization ...

Serial protein crystallography in an electron microscope

Nature Communications, 2019
Serial X-ray crystallography at free-electron lasers allows to solve biomolecular structures from sub-micron-sized crystals. However, beam time at these facilities is scarce, and involved sample delivery techniques are required.
