DESCRIPTION:Speakers: Pieter Glatzel (ESRF)\nThe highly brilliant X-ray be
 am at the ESRF allows application of sophisticated techniques for identifi
 cation of the chemical state. High-resolution powder diffraction pushes th
 e limits of solving and refining of crystal structures and investigating t
 he structure of crystalline\, defective and non-crystalline materials via 
 atomic pair distribution function (PDF) analysis. X-ray spectroscopy provi
 des an element-selective tool to study the chemical state of an analyte. H
 ere\, the ESRF has been pioneering the development of photon-in/photon-out
  spectroscopy that allows for higher spectral resolution and probes unoccu
 pied as well as occupied electronic levels (Figure 1). This technique will
  enter a new dimension with the upgrade programme ESRF-EBS where it will b
 e combined with a micron-sized beam. This unique technical development pro
 vides access to the study of “invisible” elements\, i.e. analytes in l
 ow concentration in a matrix of elements with similar atomic number.\nThe 
 presentation will provide brief explanations of the techniques\, present t
 he most important technical developments and give examples to illustrate t
 he new possibilities.\n\nhttps://events.saip.org.za/event/173/contribution

DESCRIPTION:Speakers: Wolf-Dieter Schubert (University of Pretoria)\nThe d
 iscipline of structural biology has had a rocky start and chequered histor
 y in South Africa. Despite structural biology having transformed the life 
 sciences over the last half century and the continued relevance being docu
 mented almost daily through novel revelations in the premier scientific jo
 urnals such as Nature\, Science\, Proceedings of the National Academy of S
 ciences (USA)\, New Scientist\, and novel drugs being developed continuous
 ly based on its insights\, the field has been systematically underdevelope
 d in South Africa. In the 1970’s to the 2000’s\, structural biology wa
 s seen as too expensive for universities and funding agencies in South Afr
 ica. Hence the first rotating anode generators were installed only in the 
 early 2000’s in Cape Town and Johannesburg under the respective leadersh
 ip of Profs Trevor Sewell and Heini Dirr. From these late beginnings\, the
  discipline has expanded slowly but steadily to secondary centres througho
 ut the country including Bloemfontein\, Stellenbosch\, Pietermaritzburg\, 
 Pretoria\, Richards Bay\, Potchefstroom\, Makhandla/Grahamstown and others
 . As centres are not all equally well equipped in hardware\, expertise and
  manpower\, a complex network of extensive collaborations have developed b
 etween the groups helping researchers and students in different parts of t
 he country to push their projects forward.\nDespite the hardships encounte
 red over many years and enduring into the present\, the community of struc
 tural biologists is currently fairly cohesive and still growing. However\,
  many dangers lurk that could rapidly derail the gains made over the last 
 years. These include the weak financial support in the South African fundi
 ng landscape\, the (imminent) retirement of the trailblazers in the field\
 , limited employment prospects for graduates and a resulting associated br
 ain-drain out of the country\, the poorly developed drug industry in South
  Africa\, to name just a few.\nThus while structural biology appears passa
 bly well established in South Africa at present with fairly good links to 
 international infrastructure such as the ESRF and Diamond\, the continued 
 development of the discipline will require significant will power\, hard w
 ork\, the identification of alternate funding sources\, the further develo
 pment of international ties\, and the engagement with and support from app
 ropriate representatives in the South African funding agencies and ministr
 ies.\n\nhttps://events.saip.org.za/event/173/contributions/2140/

DESCRIPTION:Speakers: Mashikoane Mogodi (University of Cape Town)\nAfrica 
 does not have a synchrotron\, and while the establishment of a synchrotron
  light source on the African continent continues to be discussed\, these i
 nitiatives get stalled by the lack of expertise on the African continent i
 n successfully designing an experiment and analysing the large amount of d
 ata. In this contribution\, I will highlight some collaborative projects b
 etween African researchers and the technology and expertise around the wor
 ld. I will also highlight the South African “Indaba”\, a series of int
 erdisciplinary workshops\, organised by the South African Crystallography 
 (SACrS)\, which assembles scientists from around the world particularly in
  chemistry. Lastly\, I will also present the “deep learning” experienc
 e at ID22 - High resolution powder diffraction beamline – ESRF. Included
  will be my scientific work at the institution which can be summarised as 
 participation in in-house research programmes\, the operation of the beaml
 ine\, providing support to external users as local contact and development
  of a personal research program.\n\nhttps://events.saip.org.za/event/173/c

DESCRIPTION:Speakers: Daniel Glaser (CSIR)\nThe lifespan and integrity of 
 critical metal components such as steam turbine blades for the power gener
 ation industry can be limited and compromised by mechanisms such as fatigu
 e and stress corrosion cracking. Conventional surface treatments such as s
 hot peening and roller burnishing are commonly used to introduce beneficia
 l compressive residual stresses to mitigate crack related phenomena. Laser
  Shock Peening (LSP) is an advanced surface enhancement process that poten
 tially achieves superior performance compared to conventional treatments d
 ue to deeper levels of compressive residual stresses. Although LSP has suc
 cessfully been adopted in the aerospace sector for titanium blade performa
 nce enhancement\, the technology is not yet typically applied for power ge
 neration applications. Systematic development of the LSP process parameter
 s applied to 12Cr steels for low pressure stream turbine blades has been p
 erformed using a number of complimentary residual stress characterization 
 techniques such as synchrotron XRD\, laboratory XRD\, incremental hole-dri
 lling\, neutron diffraction\, and the contour method. High energy synchrot
 ron X-Ray Diffraction performed at the ESRF (beamline ID15A experiment ME1
 440) has allowed for qualitative evaluation of a number of LSP parameter c
 ombinations leading toward the selection of an optimized parameter combina
 tion to be applied to full scale components.\n\nhttps://events.saip.org.za

DESCRIPTION:Speakers: Jonathan Wright (ESRF)\nAtomic structures can be det
 ermined 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 av
 ailable for diffraction experiments in many beamlines. Detector upgrades a
 re also planned in order to get the full benefit of these source improveme
 nts. \nIn many cases\, these upgrades will increase the range of samples f
 or which we can obtain atomic information\, to ever smaller crystals and a
 lso with higher resolution in time and space. There are a range of new tec
 hniques available where we can obtain images of samples by scanning small 
 beams while recording X-ray diffraction data. The EBS upgrade will enable 
 these very demanding methods to be used for in-situ studies\, so that we w
 ill be able to see what the atoms are doing inside of complex materials an
 d evolving micro-structures. Examples of recent highlights from ESRF will 
 be presented with a view towards the new possibilities planned for 2020.\n

DESCRIPTION:Speakers: Gordon Leonard (ESRF)\nThe ESRF’s facilities for S
 tructural Biology comprise 6 end-stations for macromolecular crystallograp
 hy (MX) 1\, one end-station for BioSAXS experiments 2 and one end-station 
 based around a Titan Krios cryo-electron microscope 3. These are supplemen
 ted by a number of support laboratories including the iCOS facility for in
  crystallo optical spectroscopy 4 and a facility for the high pressure cry
 o-cooling and/or derivatisation of crystals of biological macromolecules 5
 . This talk will describe the instrumentation and experimental possibiliti
 es available on these end-stations\, with a particular emphasis on automat
 ion\, remote access and mail-in services.\nThe ESRF Extremely Brilliant So
 urce (EBS) project (see http://www.esrf.fr/about/upgrade for details) will
  provide benefits for many areas of synchrotron-based science. This presen
 tation will thus also look ahead to the evolution of the ESRF’s faciliti

SUMMARY:Synchrotron microtomography in palaeontology\, a bright future for

DESCRIPTION:Speakers: Paul Tafforeau (ESRF)\nThe first application of X-ra
 y synchrotron microtomography in palaeontology was performed in 2000 at th
 e 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 synch
 rotron microtomography the golden standard for non-destructive imaging of 
 internal structure in fossils\, when conventional microtomography reaches 
 its limit. Considering the exceptional fossil record preserved in South Af
 rica\, palaeontology became a major collaborative topics between the ESRF 
 and South-Africa during the last decade. More recently\, archaeological ap
 plications have joined this portfolio. In most of synchrotrons using micro
 tomography\, sample size is typically limited to few millimeters in most o
 f the beamlines\, with only a handful of them allowing specimens in the de
 cimeter range. Larger specimens are typically imaged with high energy conv
 entional X-ray tomographs\, but with severe restrictions in term of resolu
 tion and sensitivity. There is a clear lack of solution for high-sensitivi
 ty imaging in large fossils.\n\nThe BM18 beamline project at the ESRF\, ma
 de possible by the development of the EBS new source\, aims to tackle thes
 e limitations all at once by making possible synchrotron multi-resolution 
 imaging on much larger samples than today\, with special emphasis on fossi
 ls and natural and cultural heritage specimens. In addition to the other b
 eamlines that were already involved in the thematics (ID19\, ID17\, BM05) 
 BM18 will be able to image specimens up to 1 m in diameter and 2.5 m verti
 cally. It will cover a pixel size range from 200 µm down to 1 µm\, thank
 s to a 30 cm wide polychromatic beam able to reach 300 keV\, tunable in fl
 ux\, spectrum and geometry through various in-line X-ray optics. The whole
  beamline is designed for multi-resolution investigations using semi-autom
 atic multi-detector system. The exceptional coherence properties of the ES
 RF-EBS\, coupled with the 38 m of propagation on BM18 will allow phase con
 trasts imaging capabilities without equivalent worldwide.\nBM18 should ope
 n tremendous new research capabilities for paleontology\, but also for man
 y other research fields\, including archaeology\, cultural heritage or evo
 lutionary biology. The expected start of first user operations is planned 
 for September 2021.\n\nhttps://events.saip.org.za/event/173/contributions/

DESCRIPTION:Speakers: Harald Reichert (European Synchrotron Radiation Faci
 lity)\nThere is a strong competition for beam time at the ESRF. Access is 
 based on submission of a Research Proposal. The proposal success rate aver
 ages 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 ser
 vice interruption\, the proposal submission deadlines for the next round o
 f beam times are in January and March next year - depending on the type of
  access required. The purpose of this session is to provide information on
  the proposal writing and submission process\, so that South African resea
 rchers can be ready for the Proposal Submission deadline early next year. 
 There is also opportunity at this conference for new users to identify par
 ters who are experienced users. This can greatly increase the success rate
  of applications for new users. It is particularly useful to partner with 
 beamline scientists from the ESRF\, or other collaborators\, who are famil
 iar not only with the proposal process\, but also the samples preparation\
 , the measurements and the analysis of synchrotron data.\n\nhttps://events

DESCRIPTION:Speakers: David Billing (University of the Witwatersrand)\nSol
 id Oxide Fuel Cells (SOFCs) and Solid Oxide electrolyser cells (SOECs) are
  exciting electrochemical devices that could provide unique and revolution
 ary solutions to some of the renewable energy challenges facing society. C
 entral to the design of these devices is the need for a solid electrolyte 
 that is an excellent oxygen ionic conductor whilst simultaneously being an
 d electronic insulator. Additionally the materials needs to be mechanicall
 y tough and remain chemically inert in harsh operating environments.  The 
 architype materials used as solid electrolyte in most SOFCs include YSZ (Y
 ttrium stabilised Zirconia) and CaSZ (Calcium stabilised Zirconia) with th
 e Y or Ca dopants present at around 8 to 10% level. As the performance cha
 racteristics of these materials are not completely satisfactory\, there is
  a definite need for improved alternatives. \n\nOur research has focused o
 n gaining a fundamental understanding of the mechanisms governing the tran
 sport properties of these and closely related materials. Typically the cub
 ic forms (Space group Fm-3m) of these materials exhibit higher oxide ion c
 onductivity due to the presence of vacant anionic sites. Our research has 
 included the development of suitable synthesis\, preparation and processin
 g methodologies\, particularly for the more novel materials\, followed by 
 structural\, crystallographic\, electrochemical and spectroscopic characte
 risation. Noteworthy\, as SOFCs and SOECs have operational temperatures ra
 nging from around 300°C to 1000°C\, we perform XRD\, PDF(1)\, Raman and 
 EIS measurements between ambient to 900°C or 1000°C. Consideration of th
 e results obtained for the array of distinct materials we have prepared\, 
 has highlighted the central role of short range order\, as well as the imp
 ortance of microstructure on the overall transport properties of the mater
 ials. \n\nI will present a selection of our results to date\, including th
 e results obtained from total scattering experiments performed on ID22 at 
 the ESRF in Grenoble as well as 28-ID-1 at NSLS-II at BNL. Analysis of the
  data shows structural differences when comparing the structure as perceiv
 ed on the nano-scale with the bulk average structure. The implications of 
 this for the transport properties of all energy materials is profound\, an
 d will be described.\n\nSynchrotron techniques are central to insight into
  the real structure – property relationships\, to this end we have addit
 ional experiments planned (beamtime approved) for NSLS-II\, Diamond and SS
 RL. I will also present some of the unique aspects of some of the planned 
 experiments.\n\n\n(1)    S. J. L. Billinge\, “Nanostructure studied usin
