Ruhr-Universität Bochum (RUB), Lehrstuhl für Analytische Chemie II (NanoEC)
Kristina Tschulik received her doctorate from TU Dresden in 2012 and worked as a postdoctoral fellow at the Leibniz Institute for Solid State and Materials Research Dresden and at the University of Oxford. Afterwards she established the working group for “Electrochemistry and Nanoscale Materials” at Ruhr-University Bochum, where she has held the Chair for Analytical Chemistry II since 2018.
Activities
As Principal Investigator, Professor Tschulik is a member of the Cluster of Excellence Ruhr Explores Solvation RESOLV, the graduate college “Confinement Controlled Chemistry”, the international training network “Single-Entity Nanoelectrochemistry SENTINEL” and the Transregio SFB/TR 247 “Heterogeneous Oxidation Catalysis in the Liquid Phase”.
Awards
Among her most important honors are the “Dissertation Award of the Leibniz Association” (2013), the “International Society of Electrochemistry Award for Analytical Electrochemistry” (2017) and the “Hellmuth Fischer Medal” of the DECHEMA (2018). In addition to that she has received highly prestigious fellowships like a returnee program of North Rhine-Westphalia (2015–2020), a Marie Curie Intra European Fellowship (2012–2015) and a PhD scholarship of the Studienstiftung des deutschen Volkes (2009–2012).
Focus
Tschulik develops new electrochemical and spectroelectrochemical methods for the characterization of nanoparticles in the liquid phase, both with regard to their physical properties, such as size, composition and structure, and their chemical reactivities in electrocatalysis and corrosion.
A further focus of her research is magnetic field-supported electrochemistry, in which locally superimposed magnetic fields are specifically used to control electrochemical reactions.
Methods
A combination of dark-field microscopy and electrochemistry can make individual nanoparticles in a liquid medium visible. The technique is suited to determine the activity of catalysts (…)
High reaction rates even without precious metals
Precious metals are often efficient catalysts. But they are expensive and rare. However, it has so far been difficult to determine how efficient non-precious metal alternatives are. Non-precious metal nanoparticles could one day replace expensive catalysts for hydrogen production. However, ... more
Drug resistance: Preventing drugs from being transported
Certain membrane proteins specialise in transporting molecules out of cells – a problem for the efficacy of cancer medication and antibiotics. An international research team has investigated the transport mechanism of a bacterial membrane protein using an artificially produced antibody frag ... more
Monitoring the lifecycle of tiny catalyst nanoparticles
Since they are so tiny, it is difficult to investigate single nanoparticles. However, this is exactly what researchers are aiming for in order to tailor their properties. A novel approach: particle at the stick. Nanoparticles can be used in many ways as catalysts. To be able to tailor them ... more
Light plus current: The formula for researching what happens to individual nanoparticles
A combination of dark-field microscopy and electrochemistry can make individual nanoparticles in a liquid medium visible. The technique is suited to determine the activity of catalysts during their use. more
Vibrational spectroscopy - Label-free imaging
Spectroscopic methods are now granting us deep insights into biological systems at previously unattainable spatial and temporal resolutions. Complementing the already well-established fluorescence spectroscopy, the major potential of label-free vibrational spectroscopy has become clear in r ... more
