DESCRIPTION:Prof. Marianne Liebi\, PSI/EPFL\nAbstract \nMicroscopy in sca
 nning mode allows to image different contrasts from the sample\, by probin
 g not only absorption and phase contrast of the sample but for example a f
 ull X-ray fluorescence spectrum or a 2D scattering pattern. Small- and wid
 e-angle X-ray scattering (SAXS/WAXS) imaging is in particular valuable for
  heterogeneous samples\, in which structural elements in the nano- or Ång
 ström-scale change over macroscopic length scales\, thus several millimet
 ers or centimeters. The scattering patterns provide statistical informatio
 n in each scan point\, thus this method is complementary to high-resolutio
 n imaging techniques. The information extracted from each scattering patte
 rn can be used to create images with different contrast\, such as density 
 of nano-scale features or orientation of nanostructures. These methods can
  also be combined with computed tomography to study the inside of three-di
 mensional samples. A range of applications will be shown from biological t
 issues to various soft-matter systems.\n\nBiography \nMarianne Liebi is T
 enure-Track Assistant Professor at EPF Lausanne and head of the group “S
 tructure and Mechanics of Advanced Materials” at PSI. She has been appoi
 nted in 2021 at EPFL where she is part of the Institute of Materials withi
 n the School of Engineering. Marianne Liebi studied Food Science at ETH Zu
 rich where she also obtained her PhD in 2013 in the Laboratory of Food Pro
 cess Engineering lead by Prof. Erich J. Windhab. Within this project start
 ed using small-angle neutron scattering at PSI for the characterization of
  soft-matter\, namely of magnetic alignable self-assembly structures. As a
  Postdoc in the coherent X-ray scattering group at the Swiss Light Source 
 she worked from 2013-2016 on method development in SAXS tensor tomography.
  In 2016 she moved to Sweden where after a short period at the NanoMAX bea
 mline\, MAXIV Laboratory\, Lund she started her own research group in 2017
  as Assistant Professor at the Chalmers University of Technology\, Gothenb
 urg\, and became Docent in Physics in spring 2020. She kept her affiliatio
 n at Chalmers University of Technology\, where still part of her group is 
 located (Liebi research group) when moving back to Switzerland in 2020 whe
 re she was Scientific Group Leader in the Center for X-ray Analytics at Em
 pa\, St.Gallen\, before joining PSI in November 2021.  \n\nRegister here!
