Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...
Chiral metasurfaces can strongly twist the polarization of light, but how this process unfolds in space and time has been unclear. Scientists in China have now used ultrafast electron microscopy and ...
Schematic representation of the experimental setup: Attosecond pulses (violet) eject electrons (green) from a crystal surface. The photoemission electron microscope (cone-shaped instrument at top) ...
Electron microscopy has become a vital tool in structural biology, enabling researchers to visualize biological macromolecules at near-atomic resolution. Recent advances have transformed it from a low ...
With the inventions of transmission electron microscopy (TEM) in 1931 and scanning electron microscopy (SEM) shortly after in 1937, scientists gained an unprecedented ultrastructural view of the ...
Current optical and electron microscopy imaging techniques are not suited for measuring the dynamic characteristics of living microorganisms at tiny scales due to complex sample preparation methods or ...
This is an exciting time for polymer electron microscopy. Recent improvements in instrumentation are pushing resolution limits to remarkable new heights, achieving imaging at 0.5 Å, while dual beam ...
Microscopy continues to transform the life sciences. Here are five recent breakthroughs made possible by the technique.
TEM works by accelerating electrons, typically with energies between 80 and 300 kV, and directing them through a specimen thin enough for electron transmission. Because of their very short wavelength ...
