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 ...

(Nanowerk News) The precise control of electron beams in so-called transmission electron microscopes (TEM) makes it possible to analyze materials or molecules at the atomic level. Combined with short ...

In transmission electron microscopy (TEM), where the electron beam passes through the sample to be directly imaged on the detector below, it is often necessary to support the thin samples on a grid.

In this interview, AZoMaterials speaks with Professor Sarah Haigh, Professor of Materials Characterization at the University of Manchester, about her pioneering work in electron microscopy and its ...

Gold is generally associated with pyrite (iron disulfide, FeS2), and pyrite-induced gold precipitation is critical to the ...

Responsive technique: Jonathan Peters using an electron microscope at Trinity College Dublin (Courtesy: Lewys Jones and Jonathan Peters/Trinity College Dublin) A new scanning transmission electron ...

When light passes through a material, it often behaves in unpredictable ways. This phenomenon is the subject of “nonlinear optics”, which is now integral to technological and scientific advances – ...

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 ...

They can image a wide range of materials and biological samples with high magnification, resolution, and depth of field, thereby revealing surface structure and chemical composition. Industries like ...
