In a research career spanning the last 50 years, Barry has made a huge impact in materials science - especially in advancing our understanding of the role and nature of defects in metals, semiconductors and ceramics.

Using various techniques including transmission electron microscopy, high resolution TEM, and electron diffraction, Barry has established himself as an internationally distinguished researcher who has made critical contributions to both the science and application of microscopy.

Barry, who remains an active Emeritus Professor at the University of Connecticut, and as a Distinguished Affliliate Scientist at the Sandia National Laboratory, has also made vital contributions to microscopy education at the undergraduate, graduate and post-graduate levels.

Professor Williams is synonymous with Analytical Transmission Electron Microscopy (ATEM) having pioneered its development and applications to a broad range of materials.

Over the past 45 years his work has led to a new understanding of materials and microstructural evolution, including segregation, precipitation phenomena, phase diagrams and phase transformations in metals and alloys.

Among his achievements, Professor Williams is widely recognized for his prolific research in Al alloy metallurgy – particularly in his pioneering research into Al-Li alloys, as well as fundamental research in EELS and STEM-EDX microanalysis.

Mervyn Miles is currently Emeritus Professor of Physics, School of Physics, University of Bristol and a Fellow of the Royal Society. He was one of the UK pioneers of scanning probe microscopy (SPM) and in particular its development and application to biological systems. In the mid-1980s he was one of the first researchers to apply scanning tunnelling microscopy to protein imaging. He went on to apply atomic force microscopy (AFM) to a range of biological systems, first at the Institute of Food Research in Norwich, and then, from 1990 in Bristol. On moving to Bristol, he started to work on development of SPM techniques, first scanning near field optical microscopy, and then AFM. After developing liquid Q-control, a method for enhancing force sensitivity for biological imagine, he went on to pioneer high speed AFM. This is one of the major roadblocks in the applicability of AFM, both for following processes and for rapid surface analysis and industrial applications, and the Miles group has been one of the two leading groups in this field in the world (the other being that of Prof Toshio Ando, Kanazawa University, Japan). The approaches taken by Mervyn elegantly side-stepped some of the traditional barriers to high-speed scanning, and are just now, fifteen years later, starting to be incorporated into commercial laboratory machines.
