Physicists are clamoring to use a new microscope that captures details of materials they'd never seen before. “It was a little bit like everyone was flying biplanes, and all of a sudden, here’s a jetliner.” (From 2018)
. Using its beam of electrons, scientists have glimpsed many types of viruses for the first time. They’ve used it to study parts of biological cells like ribosomes and mitochondria. You can see individual atoms with it.
Each dot in this image is a single molybdenum or sulfur atom from two overlapping but twisted atom-thick sheets. Cornell University's transmission electron microscope, which took this image, broke the record for highest-resolution microscope this July.Now the rest of the field is clamoring to outfit their scopes with similar cameras, says Muller. “You can see all sorts of things you couldn’t before,” he says.
Postdoctoral researcher Zhen Chen took the record-breaking images on a custom-designed microscope at Cornell University.to the open source physics website arXiv, a team led by McMorran has developed a new type of image you can take with the microscope. This method can image materials normally transparent to electrons, such as lightweight atoms like lithium. It should allow scientists to study and improve lithium-based batteries with atomic detail.
These new capabilities can help scientists like Mary Scott, a physicist at the University of California, Berkeley, who studies nanoparticles smaller than a bacterium. Scott has spent long hours photographing these tiny inanimate clumps under an electron microscope. Using a special rig, she carefully tilts the sample to get as many angles as possible. Then, from those images, she creates an extremely precise 3-D model, accurate down to the atom.
