Continuing Bragg Legacy of Structure Determination

08.09.2014

Over 100 years since the Nobel Prize-winning father and son team Sir William and Sir Lawrence Bragg pioneered the use of X-rays to determine crystal structure, University of Adelaide researchers have made significant new advances in the field.

Published in the journal Nature Chemistry today, Associate Professors Christian Doonan and Christopher Sumby and their team in the School of Chemistry and Physics, have developed a new material for examining structures using X-rays without first having to crystallise the substance.

“2014 is the International Year of Crystallography, recognising the importance of this 100-year-old science and how it underpins a vast range of the technological developments of our modern society,” says Associate Professor Sumby.

“Today, crystallography is an area of science that’s still providing new insights into the structures of materials – our new research is a prime example of that. It allows us to study chemical reactions that have just happened, or potentially even while they are still happening, which we can’t do using normal crystallography.”

The researchers are using a new nanomaterial – called a metal-organic framework – to bind the metal complex catalyst and its chemical reactants in place.

“We can then examine the structures of the reaction products using X-rays without having to isolate the product or grow crystals,” says Associate Professor Doonan.

“We are effectively taking snap-shots of the chemistry, enabling us to study the reaction products in their native state. In this way we can provide structural evidence for the chemical transformations that are taking place.”

The research, being undertaken in the Centre for Advanced Nanomaterials, is supported by the Australian Research Council and the Science and Industry Endowment Fund.

Sir William Bragg started his work on X-rays and crystal structure when he was Elder Professor of Mathematics and Physics at the University of Adelaide. His son Lawrence was a graduate of the University. The new work is being carried out in the Bragg Crystallography Facility at the University’s North Terrace campus.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
