SUMMARY:Multiscale structural characterization by scanning SWAXS imaging
DESCRIPTION:Zoom webinar | Replay on Youtube\n  \nKim Nygård\, \nMAX IV\, Sweden \nSmall- and wide-angle x-ray scattering (SWAXS) in scanning-imaging mode provides means to locally characterise the nanoscale structure of materials over macroscopic volumes. Here we will introduce the technique\, provide a few illustrative examples\, and discuss challenges for new users of the technique.

SUMMARY:Hyperspectral Imaging and microscopy
DESCRIPTION:Zoom webinar | Replay on Youtube\n  \nCristian Manzoni\, \nIFN-CNR & Polimi\, Italy \nSpectral imaging\, also known as imaging spectroscopy\, refers to methods and devices for acquiring a complete light spectrum for each point in the image of a scene. It provides much richer information with respect to standard imaging\, enabling to identify materials or detect dynamical processes. Spectral imaging has been applied to a wide range of scientific investigations\, such as remote sensing\, pigment determination in biology\, medicine\, coastal ocean imaging\, water analysis\, agriculture\, cultural heritage and archaeology\, just to cite a few. In particular\, hyperspectral imaging aims at acquiring the whole continuous spectrum of each point of the scene. A powerful approach to this aim is to combine classical imaging with Fourier-transform spectrometry [1]. \nHyperspectral imaging in the Thermal infrared of a sample with mineral and artificial quartz. Left: False RGB image\, synthesized from the spectral data; Right: spectral emissivity.\nIn this talk\, I will describe the main properties of the spectral imaging and the current acquisition approaches. I will also show the most recent advancements obtained at the Istituto di Fotonica e Nanotecnologie (IFN-CNR)\, based on an innovative optical device [2]. \nOur compact hyperspectral system is able to acquire spectral reflectance and fluorescence images with high sensitivity\, broad spectral coverage and high spectral resolution. Examples of hyperspectral remote-sensing and microscopy images will be provided and discussed [3]. \nHyperspectral microscope fluorescence imaging of Invitrogen slide #1 (MitoTracker® Red CMXRos +Alexa Fluor® 488 phalloidin). Excitation: 2 lasers at 478 and 562 nm; Objective: 20X\, 0.45 NA. (a) Fluorescence of Filamentous F-actin at 470-550nm; (b) Fluorescence of mitocondria at 570-680 nm; (c) Merged maps.\nReferences \n[1] S.P. Davis\, M.C. Abrams\, and J.W.
