Breakfast Seminars - Fall 2015

Materials@LU Breakfast Seminars

The Materials@LU breakfast seminars is an opportunity to find out more about materials-related research taking place within the university.

At each event, a new research group at LU invites you to come and have a cup of morning coffee and listen to an informal presentation of their current research activities and possibly also to take a tour through their research labs.

Join this opportunity to get to know materials research at LU and find out more about what your colleagues are up to and what experimental resources are available.

The information on this page is continuously updated.

The hosts during the fall semester 2015 will be:

October: The Division of Nuclear Physics

November: The Department of Orthopaedics and the Department of Biomedical Engineering

December: The National Center for High Resolution Electron Microscopy (nCHREM)

These events are further detailed below.

October: The Division of Nuclear Physics

Time: October 9th, at 9.15 am

Place: Room H422 at the Physics Department.

How to get there: Enter the building from Professorsgatan 1, turn left and walk to the end of the corridor. Take the stairs two floors up. Room H422 lies next to the Rydberg lecture room (previously "Sal B").

The research profile of the division is broad and ranges all the way from aerosol research to nuclear structure physics.  It can be divided into three main research areas:

Aerosol physics. The Aerosol group has a very close collaboration with the Aerosol group at Ergonomics and Aerosol Technology (EAT) and part of group is localized in the Design building where the large Aerosol laboratory is situated. The group has also very strong connection to the Applied Nuclear Physics group, both through common projects and through shared laboratory resources (accelerator beam line for ion beam analysis). The aerosol group has a broad range of local, national and international multidisciplinary projects with focus on climate and health.

Applied Nuclear Physics research is performed in two groups, the AMS-group and the Nuclear Microprobe group (NMP), with close technical collaboration and interdisciplinary research programs. Both groups are dependent on local heavy equipment and the NMP group has an extra support from LTH for running the accelerator laboratory. Most projects are within the field of Applied Nuclear Physics which is by its nature interdisciplinary. Collaborators can be found in medicine, biology, geosciences and industry but also archaeology.

Experimental  Nuclear Physics experiments are performed both locally, in particlular at MAX-lab, and at international sites. There are two main research groups, the photo nuclear reaction group and the nuclear structure group. Both groups are involved in large international collaborations. The involvement of physicists in detector and system development is important and it connects the activities both to the applied nuclear physics group and to other groups at the department and faculty. The Experimental nuclear physics group has an ongoing collaboration with Medical Radiation Physics regarding detector development.

November: The Department of Orthopaedics and the Division of Biomechanics

Time: To be announced

Place: To be announced

Our Biomechanics group's research is focused on understanding the link between mechanics and biology in the musculoskeletal system. More specifically, our research involves biomechanics, pathologies and repair of skeletal tissues using tissue characterisation methods, imaging and computational simulation techniques. Our research has direct applications in orthoaedics, where clinicians are looking for improved methods or understanding of repair of skeletal tissues, e.g. bone, cartilge and tendons.

September (preliminary): The National Center for High Resolution Electron Microscopy (nCHREM)

Time: September (preliminary)

Place: To be announced

The central objective of the research group in high resolution electron microscopy at the Chemical Center in Lund has been the study of the local crystal structure and the nature of structural defects by direct imaging of atomic positions.

For those crystals which are sufficiently resistant to irradiation damage, excluding most organic materials, it has become common-place to obtain images using electron beams with an energy of 100 keV to 1 MeV directly parallel to a crystal axis (preferably shorter than 10 Å) so that a two-dimensional image of the structure can be observed showing details of the arrangements of atoms.

The resolution of electron microscopes has improved gradually, and it is now possible to achieve a resolution better than 1.7 Å and with new abberration correctors for the lenses, the resolution will be below 1 Å. This of course results in images with clearer details of crystal structures. Converging the electron beam to a sub-atomic spot makes chemical analysis of virtually each row of atoms a reality.

It is no trivial matter to make full use of the resolution in the instruments now available. The precision needed for controlling the experimental variables increases rapidly as the resolution limit is improved. For this reason the use of the microscopes must be performed together with a well trained scientist of the microscopy group.
