X-ray coherence-based imaging comprises several powerful techniques which allow investigations in the different scientific fields, including biology and life sciences. The non-crystalline nature of such samples can be explored by coherent diffractive imaging (CDI) and ptychography and cellular…
Read MoreRecent progress in 3D coherent x-ray diffraction imaging methods can enable high resolution structural imaging of nano-structured crystalline materials. In this talk, I discuss developments in Bragg coherent diffraction imaging (BCDI) and Bragg ptychography that aim to broaden the envelope of…
Read MoreIn this presentation, I will first review the principles of the Bragg ptychography approach, before detailing a selection of scientific results obtained with this novel crystalline microscopy. I will finally discuss some exciting perspectives opened by the advent of the fourth generation…
Read MoreThere has been much interest in topological defects of spontaneous polarization as templates for unique physical phenomena and in the design of electronic devices. Experimental investigations of the complex topologies of polarization have been limited to surface phenomena, which has restricted the…
Read MoreCoherent Diffraction Imaging in Bragg geometry is used to study crystalline samples to access, along with morphology, also information on strain fields, defects and other atomic -scale features. This webinar will focus on the following points..... * the basic concepts of the technique and data…
Read MoreFlocculants are usually polymeric molecules which cause the aggregation of particles in suspensions and will modify the sedimentation of particles. The gravitational field and the hydrodynamics of the aggregates result in a situation where larger aggregates sediment more quickly for less efficient…
Read MoreNeutrons are powerful probes for the study of biological samples as they are very sensitive to hydrogen(H)-rich materials and can discriminate between isotopes of the same element. Due to this property of neutrons, they can be used to observe hydrogen and it’s isotope, deuterium in materials. To…
Read MoreX-rays are excellent probes for studying many different types of matter ranging from biological macromolecules to porous rocks at resolutions far beyond what is possible using optical wavelengths. However, when it comes to imaging, X-rays have one glaring weakness: it’s very hard to make a good…
Read MoreVideo lecture on LINXS YouTube - watch the video at YouTube.com Speaker: Cinzia Giannini, National Research Council, Bari This webinar is part of LINXS webinar series, Let's Dive into the Atoms. The aim is to create a fundamental understanding of how you as a researcher can use x-rays and neutrons…
Read MoreThis webinar presents the fundamentals behind coherent X-ray imaging techniques that exploit the high-brilliance provided by X-ray free-electron lasers and diffraction-limited storage rings. For such purpose, we will introduce the fundaments of i) interactions of X-rays with matter, ii) coherence…
Read MoreThe efficient use of X-ray and neutron diffractometers is often hindered by complicated data analysis software that creates barriers to entry for novice users and may even reduce efficiency for advanced users. The talk presents easyDiffraction, a software developed to interface with a very wide…
Read MoreSasView is an open source, collaboratively developed software for analysis and modeling of small angle scattering (SAS) data. The core functionality of SasView includes fitting of model functions, pair-distance distribution function inversion, model-independent analysis and correlation function…
Read MoreAfter an introduction introduction to neutron scattering and the ESS, the challenges associated with providing scientists with appropriate tools to analyze their data from ESS is discussed together with a discussion on how the demand for reproducible results, FAIR data, and the promotion of the…
Read MoreMOOC on the Coursera platform (click here) This course takes you on a journey through the technologies used in particle accelerators: The microwave system which produce the electromagnetic waves that accelerate particles; The magnet technology for the magnets that guide and focus the beam of…
Read MoreMOOC on the Coursera platform (click here) Did you know that in the year 2000 there were more than 15 000 particle accelerators in the world? Today there are 30 000 of them! A third of the particle accelerators are dedicated to medical applications, such as radiotherapy, and about half are used for…
Read MoreMOOC on the Coursera platform (click here) The NPAP coourse “Medical Applications of Accelerators” is one out of three courses in the Nordic Particle Accelerator Program (NPAP). Here you will be taken on a tour focusing on the medical applications of particle accelerators. You will see that there…
Read MoreThe conversion of dinitrogen to ammonia is a challenging, energy intensive process, which is enabled biologically by the nitrogenase family of enzymes. The Mo-dependent nitrogenases contain two cofactors, the 8Fe-8S P-cluster and the Mo-7Fe-9S-C iron-molybdenum cofactor, known as “FeMoco”, which is…
Read MoreMatter absorbs and scatters X-rays. Spectral analysis of the X-rays reveals a wealth of information about the electronic structure of the X-ray absorbing element (the analyte). Pieter Glatzel explains the mechanisms that lead to the chemical sensitivity and show how they influence the spectral…
