Master thesis "Creation of an LEIS reference data collection"
IONTOF is a manufacturer of innovative surface analysis instruments with various product lines for Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) and Low Energy Ion Scattering (LEIS).
Founded as a classic spin-off of the University of Münster, IONTOF is today the technological pioneer in the field of ToF-SIMS and LEIS devices. To strengthen our leading position, we would like to give students the opportunity to gain insight into these fields and write a master's thesis.
Description of the activity
Improve the quantification of LEIS spectra and build a collection of reference data:
*
Learning the basics and application of LEIS as well as operation of the device, incl. software for device control and data evaluation
*
Development and implementation of a measurement plan, including sample selection, preparation, in-situ pretreatment to eliminate atmospheric contamination and analysis under different measurement conditions.
*
Data analysis, visualization and structured data storage of measurement results
*
Validation of results by using multiple samples and, if necessary, various LEIS devices
*
Ideally, preparation of a manuscript for a data-oriented scientific journal (peer-reviewed)
Expected qualification
*
Advanced study of materials science, Analytic chemistry, surface sciences or scientific instrumentation
*
Ability to learn quickly and in a structured way, to work with attention to detail, both in the laboratory and in documentation
*
Interest in the described task and the improvement of an innovative surface analysis method
Our offer
*
Intensive training of all aspects of LEIS (ideally as an internship/project work before starting the Master's thesis)
*
Insights into a global company in a scientific/high-tech environment
*
Responsibility for the project and space for your own ideas
Postdoc (m/f/d) in the field of Surface Science of Energy Related Materials
Founded in 1607, Justus Liebig University Giessen (JLU) is a research university rich in tradition. Inspired by curiosity about the unknown, we enable around 26,500 students and 5,700 employees to advance science for society. Join us in breaking new ground and writing success stories - your own and those of our university.
Support us as of now in full-time as a Postdoc (m/f/d) in the field of Surface Science of Energy Related Materials
The position is to be filled within the framework of the EU-funded project ”Innovation Laboratory Process Diagnostics” at the Chair of Physical Chemistry (apl. Prof. Dr. Marcus Rohnke), Institute of Physical Chemistry at the Faculty of Biology and Chemistry for a limited period until 30 June 2027. The salary is in accordance with the collective labour agreement of the State of Hesse (E 13 TV-H).
Your tasks at a glance
As part of the project, you will construct electrochemical cells (e.g. Na batteries or electrolysers) and characterise them in detail electrochemically and post mortem using surface analytical methods (ToF-SIMS, XPS, SEM). The experiments are then repeated operando in a secondary ion mass spectrometer (SIMS). The coupled operando diagnostics will be used to obtain specific information on the material degradation of the electrochemical processes taking place.
You will work on the following sub-aspects in detail:
*
Design and construction of suitable electrochemical cells
*
Design and establishment of a sample holder for operando measurements in SIMS using liquid electrolytes
*
Carrying out and analysing electrochemical measurements coupled with mass spectrometry
*
Development of a transfer concept for the use of diagnostic findings and tools in industry
*
Supervision of student work
*
Participation in project meetings and national and international scientific conferences
*
Publication of the results in scientific journals
Your qualifications and competences
*
A university degree in chemistry, physics or materials science with a grade of at least ‘good’ (MSc, Diplom, first state examination or equivalent qualification)
*
Completed doctorate
*
Previous knowledge in the field of electrochemical energy storage
*
Experience in the investigation of ion transport and interfacial properties of electrochemical cells is desirable
*
Experience in handling/operating large-scale surface analytical equipment (e.g. SIMS, XPS)
*
Experience in handling glove boxes is an advantage
*
Confident command of German and/or English (spelling and grammar)
*
Very good communication skills and an interdisciplinary, open mindset
Very good expression and writing style in relation to scientific publishing.
Our offer to you
*
Interdisciplinary research in the field of analytics of energy-relevant materials with excellent equipment in a world-renowned research institute
*
A varied job with flexible working hours
*
Free use of local public transport (LandesTicket Hessen)
*
More than 100 training seminars, workshops and e-learning opportunities per year for personal development, as well as a wide range of health and sports activities
*
Remuneration according to TV-H, company pension scheme, child allowance and special payments
*
Good compatibility of family and career (certificate "audit familiengerechte hochschule")
