Beschreibung

Through cutting-edge research in the fields of ENERGY, HEALTH and MATTER, Helmholtz-Zentrum Dresden-Rossendorf (HZDR) solves some of the pressing societal and industrial challenges of our time.

Join our 1.500 employees from more than 50 nations at one of our six research sites and help us moving research to the next level

The Institute of Resource Ecology (IRE) performs research to protect humans and the environment from hazards caused by pollutants resulting from technical processes that produce energy and raw materials.

One major goal is gaining a better understanding of fundamental processes defining transport and accumulation of radiotoxic elements in the geo
- and biosphere including the food chain.

The Department of Surface Processes is looking for a
PhD student (f/m/d) Technetium interaction with metabolites and Fe(II) minerals. The position will be available from 1 April 2023. The employment contract is limited to three years.

Tc is the lightest element with only radioactive isotopes. Its molecular interactions in the environment are poorly understood. The Ph.
D. studies will focus on the interaction of Tc with metabolites and with Fe(II) minerals. Moreover, the impact of metabolites on mineral dissolution will be studied.

The interactions will be comprehensively quantified and characterized to identify the Tc molecular structure in solution and the mechanism responsible for Tc removal by minerals.

The PhD studies are part of the BMBF funded young investigator group (02NUK072) "Wechselwirkung von Technetium mit Mikroorganismen, Metaboliten und an Mineral-Wasser Grenzflächen - Radioökologische Betrachtungen" ("Interactions of Technetium with microorganism, metabolites and at the mineral-water interface - radioecological considerations").

The aim of the young investigator group is to characterize the interaction of Tc with occurring material in the biosphere (microorganisms, metabolites and minerals) under complex conditions using a variety of spectroscopic techniques as well as wet chemistry and electrochemistry.

"

Your tasks:

Determination of Tc complex formation constants with metabolites
Synthesis and characterization of Fe(II) minerals
Quantification of Fe(II) mineral dissolution rates in presence of metabolites
Technetium retention experiments with Fe(II) minerals
Characterization of the Tc structural environment both in solution (Tcmetabolite complexes) or in the solid phase (Tc-Fe(II) mineral interaction) by spectroscopic (e.g. UVvis, Raman, infrared, nuclear magnetic resonance, Xray absorption spectroscopies) and microscopic (e.g., scanning and transmission electron microscopy) techniques
Presentation of results at international conferences and their publication in peerreviewed journals

Your profile:

Very good university degree in natural science, preferably in chemistry, biochemistry, or geoscience (master or diploma)
Experience in spectroscopy (Raman, infrared, Xray photoelectron spectroscopy, nuclear magnetic resonance) and other physicochemical characterization techniques (Xray diffraction, electron microscopy) is helpful
Experience in experimental lab work, high motivation, and selfinitiation
Willingness to handle open radioactive materials in a radiation safety controlled lab is required
Ability to communicate and conduct work in an interdisciplinary research team (radiochemistry, biochemistry, geochemistry, physical chemistry) and willingness to participate in scientific conferences and workshops
Excellent fluent communication skills in (scientific) English. A basic German knowledge is an advantage

Our offer:

An exciting working environment on an attractive research campus and a workplace in the middle of nature
Scientific excellence and extensive professional networking opportunities
A structured PhD program with a comprehensive range of continuing education and networking opportunities more information about the PhD program at the HZDR can be found here
The employment contract is limited to three years with the possibility of longerterm prospects
Salary and social benefits in accordance with the collective agreement for the public sector (TVöD-Bund) including 30 days of paid holiday leave, company pension scheme (VBL)
We support a good worklife balance with the possibility of parttime employment, mobile working and flexible working hours
Numerous company health management offerings
Employee discounts with wellknown providers via the platform Corporate Benefits
An employer subsidy for the VVO job ticket
