MAPEX workshop & user meeting - 3D Materials Analytics 2021

08 September 2021 from 09:00 to 13:00
Fully online event

MAPEX workshop & user meeting - 3D Materials Analytics

Developed within the investigation area “3D Materials Analytics” of the MAPEX-CF, this meeting aims to connect researchers active or interested in the fields of x-ray microscopy and x-ray computed tomography.

From biology and geosciences to materials science, scientists from the University of Bremen and external institutions will share their research with a multidisciplinary audience.

Be there and benefit from the expertise and instrumentation present on campus.

The workshop will comprise


Aims and scope

Studies of 3D bulk materials microstructures can be pivotal for the future development of sustainable materials and to the understanding of biological materials towards bio-inspired goals.

In this sense, x-ray microscopy and x-ray computed tomography surge as viable options to tackle the open questions in the scientific community.

By promoting the exchange between present and future interested researchers with the expertise of MAPEX and MAPEX-CF we intent to further develop and solidify the field of 3D materials analytics at the University of Bremen.


The workshop will be in a fully virtual format using the platform In the workshop space, you will be able to use your personal avatar to:

  • Listen to the lecture and talks in the keynote room;
  • Meet colleagues in private spaces for small group discussions.
  • Participate in round-table discussions;
