Berlin: Microscopy Conference 2019 - Poster prize for Katharina Spangenberg

This year the national microscopy conference MC 2019 organized by the German Microscopy Society (DGE) was held in Berlin (September 1-5). Six members from Prof. Wilde’s work group attended the conference to present recent results. Among the poster contributions, Katharina Spangenberg, PhD student was awarded the Best Poster Prize in her category. Katharina is currently working on relaxation and diffusion studies of amorphous materials using electron correlation microscopy (ECM). ECM is relatively new microscopy technique giving access to fast time-dependent processes near or at the glass transition temperature of metallic glasses.

ISMANAM 2019  - Prof. Wilde’s group sweeps the board

The ISMANAM symposium 2019 held in Chennai, India turned out very successful for the working group of Prof. Wilde. Due to third-party funds, he and six of his PhD students were able to attend this conference, which is the most important annual meeting of scientists, tech-nologists and students working in the field of metastable, nanocrystalline and amorphous materials. Among several interesting talks and discussions, the Münster team was honored for their research contributions: Manoel da Silva Pinto and Sven Hilke were awarded the Best Poster Award in their categories.
Moreover, the prestigious Alain Reza Yavari Award, which is the highest award of the conference series for leading scientists, was awarded to Prof. Wilde for his outstanding scientific contributions as senior researcher in the field of nanocrys-talline and amorphous materials.
Congratulations to all!

Outstanding Reviewer 2018

Prof. Gerhard Wilde and private lecturer Dr. Divinskiy were honoured as outstanding reviewers 2018 for the journal Acta Materialia.

Dr. Friederike Emeis (AG Wilde),

Dr. Vitalij Hieronymus-Schmidt (AG Wilde) and

Dr. Niklas Nollmann (AG Wilde)

finished their doctorate:
With the certificate, which was handed by Prof. Dr. Wilde (Dean of the Physics Department) on February 1st, 2019, it became official. Congratulation!


While metallic glasses are disordered systems with rather simple atomic interactions, colloids allow manipulations and observations on the single particle level. Both these material classes present models of disordered systems allowing analyses of structure-property relations and materials’ response upon external excitations with complementing opportunities with the focus on heterogeneous dynamics, shear localization, shear band formation and avalanche dynamics.
The symposium present a unique platform to utilize the complementing generic advantages, control parameters and specific analysis tools available for these two different classes of disordered materials and to approach a unified view concerning the underlying physical mechanisms that lead to system-independent universal behavior of disordered systems with respect to glass relaxation, aging, rejuvenation and shear response.
We expect in-depth discussions during the symposium and collaborations emerging from these discussions will contribute to deepen the understanding of metallic glasses and glass-formation. More information...
