Werner Heisenberg's famous uncertainty principle describes one of the most intriguing features of quantum physics: certain pairs of physical quantities describing a particle, such as position and ...

Although both a SEM and a TEM are electron microscopes, their working principles and images are very different. Whereas an SEM uses secondary electrons ejected after bombarding a sample’s surface with ...

A laser (purple) is powerfully amplified by highly polished mirrors and focused on the electron beam (blue) to shift its phase and increase the cryo-EM microscope’s contrast, allowing biologists to ...

For those of us who weren't paying attention, over the last few years, scientists around the world have been one-upping each other in a bid to create the smallest QR code that can be reliably read.

With a so-called cryo plasma-FIB (Plasma Focused Ion Beam) scanning electron microscope with nanomanipulator, Goethe University in Frankfurt (Germany) is expanding its research infrastructure with a ...

Microscopy is an imaging technique that enables us to see a world that would otherwise be invisible to us. Once upon a time, visualizing cells, microbes and other entities not perceptible to the naked ...

A butterfly net, tweezers and a drawstring bag brimming with small plastic vials: it is an unusual toolkit for a photographer, but not for Michael Benson. Over six years, he gathered specimens for his ...

(a) A scanning electron microscope (SEM) image of the nanoneedle probe used for the measurements. (b) Elasticity map of a 1 µm × 1 µm area on the nuclear surface, showing the change in elasticity ...

STARKVILLE, Miss.—Mississippi State’s Institute for Imaging and Analytical Technologies soon will be home to a scanning electron microscope so advanced that it will be the first of its kind in the ...

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 ...
