Abstract
This issue is dedicated to Regents' Professor John Maxwell Cowley, FRS, in recognition of his lifelong contributions to electron microscopy, diffraction, and crystallography. This collection of 22 peer-reviewed articles is based on presentations made at the international workshop entitled “Recent Developments and Applications of Atomic Resolution Electron Microscopy and Spectroscopy—A Silver Jubilee.” The workshop was held in the historic Old Main building on the campus of Arizona State University in early January 2003 and was attended by about 150 people. It celebrated the 25th anniversary of the Center for High Resolution Electron Microscopy, which was founded by John Cowley, and also served as an occasion to honor him on his 80th birthday. Keynote speakers included Sumio Iijima, discoverer of the carbon nanotube; Mikail Roco, senior advisor on nanotechnology for the National Science Foundation; and John Cowley himself, whose lecture addressed innovative ideas for achieving sub-Ångstrom resolution without requiring aberration correction.
