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 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 ...
1957: Marvin Minsky, a professor at MIT, invents the confocal microscope, an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of using a spatial pinhole to block out-of-focus light in image formation. This technology is a predecessor to today's widely used confocal laser scanning microscope.
He investigated the need for a brighter electron source in the microscope, positing that cold field emission guns would be feasible. [9] Through this and other iterations, Crewe was able to improve the resolution of the STEM from 30 Ångstroms (Å) down to 2.5 Å. [10] Crewe's work made it possible to visualize individual atoms for the first ...
Through the microscope, nanoparticles look like symmetric round spots. The spot width is equivalent to the point spread function (~ 250 nm) and is defined by the microscope resolution. Lateral coordinates of the given particle can be evaluated with a precision much higher than the resolution of the microscope.
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 ...
XM-1 held the world record in spatial resolution with Fresnel zone plates down to 15 nm and is able to combine high spatial resolution with a sub-100ps time resolution to study e.g. ultrafast spin dynamics. In July 2012, a group at DESY claimed a record spatial resolution of 10 nm, by using the hard X-ray scanning microscope at PETRA III. [11]
James Hillier, OC (August 22, 1915 – January 15, 2007) was a Canadian-American scientist and inventor who designed and built, with Albert Prebus, the first successful high-resolution electron microscope in North America in 1938. [1]
