PhD Researcher

At the University of Bremen, the Faculty of Production Engineering (FB04) and the Department
Process & Chemical Engineering (FG01) invites applications for the following academic position
-    under the condition of job release    -

PhD Researcher
Salary level 13 TV-L (100%), start date: as soon as possible
Reference number: A 283/18

The employment is fixed-term and governed by the Act of Academic Fixed-Term Contract, §2
(1) (Wissenschaftszeitvertragsgesetz – WissZeitVG). Therefore, candidates may only be considered
for appointment if they still have the respective qualification periods available in accordance
with § 2 (1) WissZeitVG. The position is available for three years.

In the field of
“High Throughput Designing of Aggressive Organometallic Precursor-Solvent Combinations
for Single Droplet Combustion”

Background: The Faculty of Production Engineering, University of Bremen is well known
through its cutting edge research in the areas of particle production, their use in different
applications and designing reactors/machines for specific material engineering. We are looking
forward to establish the next level gas-phase technologies for the production of sulfide/nitride
nanomaterials through environmentally friendly and safer engineering processes. The Faculty
of Production Engineering closely co-operates with the Leibniz Institute for Materials
Engineering (IWT), an independent interdisciplinary research institute with a focus on materials
science, manufacturing technology and chemical & process engineering.

Your Task: While remarkable knowledge for designing metal oxides nanoparticles and their
application has been acquired in the past, the productions of sulfides/nitrides have not yet been
as successful. Through this position you will bring reactive spray technology to the next level
and advance from metal oxide nanoparticles to sulphide/nitride materials. You will utilize fast,
safe and versatile high throughput single droplet combustion screening processes which will
be used to design spray reactors for the synthesis of novel metastable binary and/or complex
multi-metal sulphides/nitrides. You will investigative possible precursor-solvent combinations,
reaction conditions and process models for this new class of reactive sprays.

Required qualifications:

You have an above-average degree in engineering or natural sciences with a focus on chemical
and materials engineering. Basic knowledge in the field of aerosol combustion, solution chemistry,
laser spectroscopy and material characterization techniques (XRD, TEM and BET), knowledge of reactor
design/housing are required. Through your master’s thesis, you have proven your ability to work independently.
The national and international co-operation within the project requires fluency in English and German languages.
Knowledge of the MS Office applications such as Word, Excel and PowerPoint is required. Strong knowledge of
MATLAB and CAD4 for machine design is desirable.

•    A master´s degree in materials science, Chemistry and engineering and/or physics.
•    Sound knowledge in aerosol combustion, solution chemistry, laser spectroscopy and
      material characterization techniques
•    Strong knowledge of MATLAB is desirable
•    Knowledge of reactor design/housing is a plus
•    Excellent academic record and ability to work in a team and independently.
•    Excellent written and oral communication in English while communication skill in German is helpful

What we offer: You will have the opportunity to work independently in innovative research areas such as spray
technologies and materials chemistry under close supervision of experts in their field. You will be working to
establish next-level spray technology utilizing modern instruments and laser spectroscopic technique. As part
of your research work, you will have intensive contact with national and international research institutes and
universities through collaborations, visits and conferences. We offer a team-oriented, future- and practice-oriented
research environment with the possibility of scientific qualification and doctorate.
