Current team members:

Team leader

Thomas Konegger, Dipl.Ing. Dr.techn.

 

After completing his diploma studies in Technical Chemistry at Vienna University of Technology with a focus on chemistry and technology of materials in 2007, Thomas received his PhD in 2010, with a research focus on polymer-derived ceramics. He has worked as a university assistant until 2017. Since 2018, he is Assistant Professor.

Publications and CV

PhD student

Christina Drechsel, Dipl.-Ing. BSc.

 

Christina initially joined us for her master thesis in May 2015 where she worked on multiscalar polymer-derived ceramic layer structures. After her graduation in September 2016, she has continued working in our group for her PhD project, where she investigates the generation of microporosity in polymer-derived ceramics in the framework of the MICROPORE project funded by the Austrian Science Fund (FWF).

PhD student

 

Johannes Rauchenecker, Dipl.-Ing. BSc.

 

Johannes first joined our group for his bachelor thesis in 2016, working on the control of porosity in SiCN-based ceramics, and also did his master thesis in the framework of the MICROPORE project, which he completed in June 2018.
In his PhD thesis, part of the ADDHANCE project, he investigates new approaches towards shaping of aluminum nitride ceramics.

 

Master student

 

Richard Obmann, BSc.

 

In 2015, Richie had already worked in our group for a short-term individual lab on porous polymer-derived ceramic structures. Since June 2017, he has been working on his master thesis project, again dealing with pore tailoring in polymer-derived ceramics.

 

Master student

 

Matthias Nebel, BSc.

 

In his Master thesis, Matthias explores new ways to modify the structure of preceramic polymers in order to tailor structural changes during the polymer-to-ceramic conversion process.

 

Master student

 

Gregor Mikl, BSc.

 

Gregor explores new approaches towards aligned pore structures in polymer-derived ceramics.

 

Master student

 

Johannes Eßmeister, BSc.

 

Johannes joined our team in October 2018 and carries out his diploma project in the framework of an FWF/CDG-funded project led by Miriam Unterlass. In collaboration with the Unterlass Lab, Johannes develops polyimide-based composites and evaluates their mechanical and structural properties.

 

Master student

 

Felix Frank, BSc.

 

Having joined our team in December 2018, Felix works on the development of polymer-derived ceramic membranes in the framework of the MICROPORE project.

 

Project assistant

 

Deniz Akgün

 

Deniz supports our group in several processing- and characterization-related aspects, including the mechanical evaluation of ceramic materials.

 

Bachelor student

 

Samuel Stelzl

 

Samuel joined us in April 2018 to work on his bachelor thesis project involving the preparation of nano-scaled oxide powders through a freeze-drying approach.

 

Bachelor student

 

Veronika Hartinger

 

Veronika, who started her Bachelor thesis project in our group in July 2018, is working on hierarchical pore systems in alumina ceramics.

 

Bachelor student

 

Johannes Maschke

 

Johannes joined us in July 2018. He works on the development of sol-gel-based oxide layers.

 

Bachelor student

 

Ivan Delic

 

Ivan's bachelor thesis project involves the characterization of low-temperature cofired ceramics (LTCC), in the framework of a collaboration with the Institute of Sensor and Actuator Systems at TU Wien.

 

Bachelor student

 

Kirsten Rath

 

Kirsten joined us in September 2018 for her bachelor thesis. Her project involves the investigation and comparison of material properties of polymer-derived ceramics.

 

Bachelor student

 

Ella Staufer

 

Ella's bachelor thesis, which she started in October 2018, deals with the evaluation of processing parameters during the cross-linking of preceramic polymers, and their effects on the resulting material's properties.

 

Bachelor student

 

Nicholas Wakelnig

 

In his bachelor thesis, Nicholas investigates the impact of a variety of processing parameters on the structural and mechanical properties of alumina foams.
