Researchers use electron microscopy to produce high-resolution images at the atomic scale of everything from composite nanomaterials to single proteins. The technology provides invaluable information on the texture, chemistry, and structure of these materials. Research over the past few decades has focused on achieving higher resolutions: being able to image materials at progressively finer levels with more sensitivity and contrast. But what does the future hold for electron microscopy?

First 4D look at crystallising atoms contradicts textbook nucleation theory

June 27, 2019
Source: Chemistry World

For the first time scientists have watched iron and platinum atoms crystallise in 4D – not only observing their arrangement in space but tracking them over time. Their observations clash with classical nucleation theory, which describes the early stages of a phase transition, adding to growing evidence that the textbook theory is outdated and imprecise.

Watching crystal nucleation happen at atomic scale

Crystals form in storm clouds, metals, drug molecules, and even in diseased tissues. Despite their ubiquity, scientists still don’t fully understand what happens when a liquid solution first starts to form a solid crystal, a step called nucleation. Now researchers have gotten their first glimpse of the details of the process, imaging individual atoms during nucleation in metal nanoparticles (Nature 2019, DOI: 10.1038/s41586-019-1317-x).

Atomic motion is captured in 4D for the first time

Results of UCLA-led study contradict a long-held classical theory.  Everyday transitions from one state of matter to another — such as freezing, melting or evaporation — start with a process called “nucleation,” in which tiny clusters of atoms or molecules (called “nuclei”) begin to coalesce. Nucleation plays a critical role in circumstances as diverse as the formation of clouds and the onset of neurodegenerative disease. A UCLA-led team has gained a never-before-seen view of nucleation — capturing how the atoms rearrange at 4D atomic resolution (that is, in three dimensions of... Read More

More than half of the people in the world host colonies of a bacterium called Helicobacter pylori in their stomachs. Although it’s harmless to many, H. pylori can cause stomach cancer as well as ulcers and other gastric conditions. Doctors tend to prescribe multiple antibiotics to defeat the microbe, but that strategy can lead to antibiotic-resistant superbugs. Now, a finding by UCLA scientists may lead to a better approach. The researchers have determined the molecular structure of a protein that enables H. pylori to stay alive in the stomach, and elucidated the mechanism by... Read More

Paper on diffractive optics shows 3D holograms become reconfigurable by computer

October 04, 2018

Diffraction refers to a variety of phenomena occurring when a wave encounters an obstacle and bends around it. Diffractive optics are widely used today in imaging, holography, microscopy and manufacturing. Previous work has shown that extending diffractive optics from two dimensions to three dimensions enables new functionality and improves system performance. The paper suggests a way to make the two-dimensional waves three-dimensional in real time with a simple modification to existing devices controlled with a computer.
