X-ray characterization provides opportunities for scientists in the exploration of materials and living matter in many fields: chemistry, material sciences, archaeology and cultural heritage, structural biology and medical applications, environmental sciences, information science and nanotechnologies. A wide range of techniques are available one of which is X-ray imaging. This term is usually...

Atomic structures can be determined using X-ray diffraction and this technique has already had a huge impact on a wide range of scientific disciplines. The upgrade of the ESRF source will bring another order of magnitude increase in the X-ray flux available for diffraction experiments in many beamlines. Detector upgrades are also planned in order to get the full benefit of these source...

Solid Oxide Fuel Cells (SOFCs) and Solid Oxide electrolyser cells (SOECs) are exciting electrochemical devices that could provide unique and revolutionary solutions to some of the renewable energy challenges facing society. Central to the design of these devices is the need for a solid electrolyte that is an excellent oxygen ionic conductor whilst simultaneously being and electronic insulator....

The highly brilliant X-ray beam at the ESRF allows application of sophisticated techniques for identification of the chemical state. High-resolution powder diffraction pushes the limits of solving and refining of crystal structures and investigating the structure of crystalline, defective and non-crystalline materials via atomic pair distribution function (PDF) analysis. X-ray spectroscopy...

Africa does not have a synchrotron, and while the establishment of a synchrotron light source on the African continent continues to be discussed, these initiatives get stalled by the lack of expertise on the African continent in successfully designing an experiment and analysing the large amount of data. In this contribution, I will highlight some collaborative projects between African...

The first application of X-ray synchrotron microtomography in palaeontology was performed in 2000 at the ESRF on the beamline ID19. This topic has been so successful that it has become one of the very visible research topics at the ESRF, making synchrotron microtomography the golden standard for non-destructive imaging of internal structure in fossils, when conventional microtomography reaches...

The ESRF’s facilities for Structural Biology comprise 6 end-stations for macromolecular crystallography (MX) 1, one end-station for BioSAXS experiments 2 and one end-station based around a Titan Krios cryo-electron microscope 3. These are supplemented by a number of support laboratories including the iCOS facility for in crystallo optical spectroscopy 4 and a facility for the high pressure...

The discipline of structural biology has had a rocky start and chequered history in South Africa. Despite structural biology having transformed the life sciences over the last half century and the continued relevance being documented almost daily through novel revelations in the premier scientific journals such as Nature, Science, Proceedings of the National Academy of Sciences (USA), New...

The lifespan and integrity of critical metal components such as steam turbine blades for the power generation industry can be limited and compromised by mechanisms such as fatigue and stress corrosion cracking. Conventional surface treatments such as shot peening and roller burnishing are commonly used to introduce beneficial compressive residual stresses to mitigate crack related phenomena....

There is a strong competition for beam time at the ESRF. Access is based on submission of a Research Proposal. The proposal success rate averages 45%, but certain facilities are more in demand than others. Proposal are judged primarily on scientific merit. Technical feasibility, safety and ethics must also be assured. Although the EBS project has led to a service interruption, the proposal...
