Dr Grant Williams recognised in 2014 Queen's Birthday

Honours

3 June 2014

Congratulations to Dr Grant Williams who has been made a Member of the New Zealand Order of Merit (MNZM), for services to science. Such an honour is bestowed on those "who in any field of endeavour, have rendered meritorious service to the Crown and the nation or who have become distinguished by their eminence, talents, contributions, or other merits."

Dr Williams, Professorial Research Fellow at the School of Chemical and Physical Sciences, is currently involved in a number of research programmes that include the study of new materials for magnetic sensors, optical materials and methods for radiation detection, high temperature superconductivity, topological insulators, and linear and nonlinear optics.

"Part of the University’s mission is to play a leading role in shaping New Zealand’s future and our Honours recipients are doing just that," says Professor Grant Guilford, Vice-Chancellor of Victoria University of Wellington.

"I would like to extend my warmest congratulations to all our honours recipients, and thank them for using their expertise to enrich our world."

Dr Grant Williams wins Hector Medal. 

10 November 2010

The Hector Medal for physical sciences was awarded to Dr Grant Williams of Industrial Research in Lower Hutt for his internationally recognised work on the chemical and electronic structure of materials, especially high temperature superconductors. His work has led to a better understanding of the fundamental physics and the development of materials for magnetic sensors, radiation detection and imaging, and optical communication.

Podcast - Glass for radiation imaging

13 May 2010

Our Changing World, Radio New Zealand National.

Andy Edgar and Chris Varoy are developing new glasses and glass ceramics which can store radiation so that the image is held like invisible ink and then retrieved digitally later.

The materials can detect X-rays, gamma rays and neutrons, and can be used for recording images of objects placed in X-ray or neutron beams.

While there are similar products already on the market, the group is trying to improve them. As Ruth Beran finds out, the materials are batched and poured in an inert, un-reactive environment of dry argon or nitrogen gas in a “glove box". (Image and text: Our Changing World.)
