Proteins are constantly moving, but our structures of them are static. Clare Sansom talks to the researchers using free-electron lasers to make time-resolved structures ...

Atoms are the building blocks of all matter, from the air we breathe to every cell in our bodies. Yet despite their presence everywhere, no one has truly seen an atom with the naked eye ,until ...

Atomic-scale detail is now possible with photons, thanks to a cooled-down silver tip and a clever use of plasmonics.

An atom has the same number of protons as electrons, so it is neutral − it has no overall charge. Now, most of the atoms in the universe are the two simplest kinds: hydrogen, which has one proton, ...

Using a STEM-in-SEM conversion holder, we can convert a scanning electron microscope into a scanning transmission microscope. Neat!

New electron microscopy technique enables precise atomic number mapping, revealing nanoscale hydrogen storage and defect dynamics in palladium.

Scientists have captured the first-ever video of atoms in motion during a chemical reaction, revealing hidden pathways and short-lived molecules previously impossible to observe. Using a new type of ...

Scanning transmission electron microscopy experiments have uncovered the structural changes a ruthenium catalyst undergoes that increase its activity during an ammonia cracking reaction. The findings ...

In a recent article, researchers presented an iridium single-atom catalyst coordinated with cobalt–iron hydroxides, showing enhanced performance for oxygen evolution reactions (OER). This catalyst ...

Next, what’s known as an optical gating pulse initiates, allowing an infinitesimal timeframe for a one-attosecond electron pulse to then emit from the microscope.

Scanning tunneling microscopy uses a sharp probe to map the surface of a material atom by atom. Researchers at Drexel and UCLA are using the technology to get the first high-resolution look at the ...
