The chair conducts research in applied geochemistry and environmental geochemistry to investigate the geochemical cycling of elements in soils, sediments, and surface waters using an interdisciplinary approach. Our research focuses on (bio)geochemical reactions involving iron, carbon, and sulfur and their impact on trace elements in environments affected by human activities and climate change. Furthermore, we aim to develop innovative solutions to these challenges by exploring novel remediation and engineering approaches.

Thomas published his first PhD paper!

In his first PhD paper Thomas comprehensively investigates the Tc–magnetite interaction.

Magnetite is one of the primary corrosion products of steel under anoxic conditions and therefore plays a crucial role in the retention of radionuclides relevant to final disposal. In particular, the interaction of magnetite nanoparticles with technetium is relevant to safety, as previous studies have already indicated that Tc can be incorporated into the magnetite structure. However, the underlying mechanisms and the specific conditions for this structural incorporation have not yet been fully understood.

By combining high-resolution X-ray absorption spectroscopy with computer-aided modeling, Thomas made it possible to identify the conditions under which structural incorporation of technetium occurs and to elucidate the mechanism of the associated charge balancing.

BIG CONGRATS THOMAS!

A Successful Start of the Aquatic and Environmental Analytics Module

The new Aquatic and Environmental Analytics module for MSc Earth Sciences students was launched with great success. Starting from the question of whether former mining activities affect the environment in the Kappler Valley, students investigated their own water and soil samples—from field sampling to laboratory analysis and interpretation of the results.

A big thank you goes to all students for their enthusiasm, curiosity, and active participation, which greatly contributed to the success of this first edition of the module.
