"Revolutionizing Electron Microscopy: High-Resolution Imaging on a Budget"

Researchers at the University of Illinois Urbana-Champaign have demonstrated that record-breaking microscopic resolution can be achieved using electron ptychography on "conventional" transmission electron microscopes, breaking the trend of increasing microscope price with increasing resolution. This new technique, which uses computation to boost resolution, allows for deep sub-angstrom spatial resolution and rivals the highest ptychographic resolutions achieved with expensive aberration-corrected microscopes. The approach quadruples the resolution of conventional transmission electron microscopes and represents a significant paradigm shift in the field of electron microscopy.

'Doughnut' beams revolutionize microscopic imaging

Researchers at the University of Colorado Boulder have developed a new technique using doughnut-shaped beams of light to capture detailed images of objects too small to be viewed with traditional microscopes. This method, called ptychography, has previously struggled with highly periodic samples or objects with regularly repeating patterns, such as nanoelectronics. By using beams of extreme ultraviolet light shaped like doughnuts, the researchers were able to collect accurate images of delicate structures as small as 10 to 100 nanometers. This breakthrough could have applications in improving nanoelectronics and inspecting semiconductors for defects without causing damage.
