Within the Sonata BIS project, the team members (Agnieszka Drewniak, Damian Koszelow, and Jakub Karczewski), went to SLS synchrotron at Paul Scherrer Institut to perfrom in-situ observation of high-temperature oxidation process - oxide scale growth. We have (again) successfully applied for beamtime at the Tomcat line. The measurements were carried out from 30th March to 2nd April 2022.
We have previously analyzed samples after an ex-situ oxidation experiments (Materials & Design paper - LINK), and this time we wanted to check whether it can be done in-situ. After 3 days of measurements, now is time for intensive data analysis!

In collaboration with Paul Scherrer Institute in Switzerland, we were able to carry out an interesting tomography study of porous alloys, including oxidized alloys.
The main achievement of this work is the possibility to distinguish the metallic and oxide phases, making detailed 3D analysis possible.

This work has been carried out within the Sonata BIS project.

Graphical abstract:

In respect to the on the announcement from 10th December, only one candidate applied. 

Mr. Ahsanul Kabir, with MSc from University of Stuttgart and PhD from Technical University of Denmark has been interviewed and received high notes for his skills. 

Based on the interview, the selection committee has positively assessed Mr. Kabir's skills and recommend him for employment at Gdańsk University of Technology.

Within the Sonata BIS project: "High-temperature corrosion studies and development of oxidation lifetime model of alloy powders and sintered porous alloys: effects of composition and microstructure" we have an opening for PostDoc for maximum 24 months. 

The PostDoc will work on fabrication of metallic materials by means of 3D printing and tape-casting, followed by high-temperature sintering.

Our work has been published in Corrosion Science, a leading journal in the field of corrosion. 
"High temperature corrosion evaluation and lifetime prediction of porous Fe22Cr stainless steel in air in temperature range 700–900 °C"
This work is based on a collaboration of Gdańsk Tech with Paul Scherrer Institut (M. Makowska, F. Marone), where we have performed some advanced 3D imaging of porous alloys.

This article is also the first outcome of the Sonata BIS project.

We show how can we try to predict the lifetime of the porous alloys based on only short-time measurements (~150 hours). It is a simple and practical approach, supplementing other developed methods of lifetime prediction.

The article is Open Access: https://www.sciencedirect.com/science/article/pii/S0010938X21003553

Together with Kaunas University of Technology (KTU) and Warsaw University of Technology (WUT) we have been granted a NCN Daina-2 (Lithuanian-Polish cooperation call) project: "Porous metal supported micro-scale solid oxide fuel cells: fundamentals, fabrication and testing". We will work on fabrication of a novel fuel cell based on specially tailored porous metal substrate.

At PG we are looking for a highly motivated PhD student to work on development and testing of new fuel cells.
