Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which ...

From paints and inks to catalysts and drug-delivery materials, many advanced technologies rely on substances dispersed in ...

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 ...

Researchers have shown that expensive aberration-corrected microscopes are no longer required to achieve record-breaking microscopic resolution. Researchers at the University of Illinois at ...

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 ...

TEM works by transmitting a beam of electrons through an ultra-thin specimen. As the electrons interact with the specimen, they are scattered or transmitted, producing an image that is magnified and ...

(Nanowerk Spotlight) The dynamics of chemical reactions central to energy innovations unfold at nanometer lengths - a scale too small to directly witness in atomistic detail, obscured by limitations ...
