He is twice in the Guinness World Records, most recently, for achieving the highest resolution microscope image ever recorded using electron ptychography. [3] His work spans theory, computation, and experimental physics research. He is also a Faculty member of the Center for Bright Beams. [4]
In 2012 it was also shown that electron ptychography could improve on the resolution of an electron lens by a factor of five, [57] a method which was used in 2018 to provide the highest-resolution transmission image ever obtained [27] earning a Guinness world record, [58] and once again in 2021 to achieve an even better resolution.
In 1998, working with Stephen Pennycook of ORNL, he recorded "the highest resolution microscope images ever made of crystal structures". [ 9 ] [ 10 ] Six years later, Nellist, Pennycook, and colleagues at ORNL produced the first images of atoms in a crystal on sub-Angstrom scales by using a new technique to correct the optical aberrations in a ...
High-resolution transmission electron microscopy is an imaging mode of specialized transmission electron microscopes that allows for direct imaging of the atomic structure of samples. [ 1 ] [ 2 ] It is a powerful tool to study properties of materials on the atomic scale, such as semiconductors, metals, nanoparticles and sp 2 -bonded carbon (e.g ...
Aberration-Corrected Transmission Electron Microscopy (AC-TEM) is the general term for using electron microscopes where electro optical components are introduced to reduce the aberrations that would otherwise reduce the resolution of images. Historically electron microscopes had quite severe aberrations, and until about the start of the 21st ...
By Keith Morrison Taking the phrase of "putting it under the microscope" quite literally, the Nikon Small World contest recently announced its winners for 2014. Now in its 40th year, the contest ...
The 3,552-square-foot (330.0 m 2) photograph was made to mark the end of 165 years of film/chemistry-based photography and the start of the age of digital photography. It was taken using a decommissioned Marine Corps jet hangar (Building #115 at El Toro) transformed into the world's largest camera to make the world's largest picture.
Light MicrOscopical Nanosizing microscopy (3D LIMON) images, using the Vertico SMI microscope, are made possible by the combination of SMI and SPDM, whereby first the SMI, and then the SPDM, process is applied. The SMI process determines the center of particles and their spread in the direction of the microscope axis. While the center of ...
