The electron beam follows a vertical path through the microscope, which is held within a vacuum. The beam travels through electromagnetic fields and lenses, which focus the beam down toward the sample ...

As a result, scanning electron microscopy was developed to supply novel techniques for sample imaging via electron scanning. This article outlines the working principles and applications of ...

All forms of Earth life have specific chemicals in their makeup, such as amino acids and sugars. Scientists have known that ...

Kim Morgan has spent the last decade getting really, really close up to blood cells, skin flakes and more. Her artwork using ...

Electron microscopy uses a beam of electrons to illuminate a sample and achieve much higher spatial resolution than light microscopy. Transmission electron microscopy generates an image of the ...

A hybrid microscope allows scientists to simultaneously image the full 3D orientation and position of an ensemble of molecules, such as labeled proteins inside cells. The microscope combines polarized ...

Molecules friendly to life have been found in samples of the asteroid Bennu, which NASA collected with a robotic probe five years ago.

Two heads are better than one, as the saying goes, and sometimes two instruments, ingeniously recombined, can accomplish ...

Rock and dust samples brought back to Earth from the asteroid Bennu contain organic matter and a variety of minerals crucial to the emergence of life ...

This laboratory course integrates the theory and practice of scanning electron microscopy (SEM), including sample preparation, SEM operation, darkroom work, manuscript preparation, and an ...

The short answer is; no. We will never see atoms using visible light, simply because the wavelength of visible light (around 400 to 700 nanometers) is larger than the size of an atom (around 0.1 to ...
