PhD position: Search for magnetic skyrmions and topological memory in new materials by neutron and x-ray scattering
With a recently awarded FOM programme we combine theory, material synthesis and the latest experimental techniques to explore new magnetic topological states and transport effects of magnetic Skyrmions. Skyrmions are chiral nanoparticles with a vortex-like structure that occur spontaneously in certain materials. These mysterious quasi-particles challenge our fundamental understanding of condensed matter. They are also of technological relevance as they be brought into motion by very low electrical currents and might be used as information bits in the computers of the future.
PhD position: Aberration-free optical imaging in living brain tissue
Although the past decade has seen a wave of breakthroughs in light-based imaging and stimulation techniques to probe neuronal organization and activity at high spatial and temporal resolution, these techniques suffer from dramatic optical distortions as one proceeds deeper inside the tissue. Currently, wavefront shaping methods are emerging that could correct for these tissue-induced aberrations and allow deeper imaging at improved resolution. Within the NWO Programme Neurophotonics, experts in the field of single-neuron physiology (Kole, Wierenga) join forces with experts in advanced imaging and wavefront shaping technology (Mosk, Vellekoop, Gerritsen, Kapitein). The goal is use advanced light-based methodology to unravel the physical principles underlying signal generation, propagation and integration in neurons embedded in functional circuits.
PhD position: Thermal stability effects in large scale windfarms
Wind-turbines interact with the environment over a wide range of length scales ranging from millimeters (viscous scales) and meters (wakes and tip vortices) up to geophysical scales of hundreds of meters (inter-turbine spacing) to kilometers (wind-farms). The large scale separation makes analysis and design of wind-farms challenging from both a theoretical and a numerical perspective. However, a detailed understanding of the relevant physics is critical for efficient wind-farm designs that exploit the full potential of this important renewable energy source. Field experiments can provide measurements of key parameters but it is not possible to fully specify the test conditions, i.e. isolate a set of control parameters, which makes it very difficult to separate different effects. High-fidelity simulations on the other hand offer the possibility to set the control parameters exactly and thus allow one to fully specify the conditions under which the wind-farm performance is tested. This makes simulations the ideal tool to obtain insight into the complex interactions that dictate wind-farm performance.
PhD position: The surface chemistry of Fischer-Tropsch synthesis catalysts
DIFFER, Syngaschem BV and the TU/e work together in an industrial-private partnership financed by Syngaschem BV and NWO. Within the overarching theme of 'Electricity to Chemistry, Catalysis for Energy Storage' we investigate novel approaches to use electrical energy, water and CO2 to produce chemicals that are easy to handle and suitable for long term storage. This theme addresses the current need to efficiently capture and store electricity from sustainable but intermittent sources such as wind and solar power. Synthesis gas, mixture of CO and hydrogen, plays a central role in the project. The PhD project focuses on the fundamental aspects of the conversion of synthesis gas into liquid hydrocarbon fuels via the Fischer-Tropsch synthesis process. In the experimental approach taken single crystal model catalysts will be studied in an ultrahigh vacuum environment to obtain more detailed understanding of the reaction mechanism of this complex reaction. The research will be performed in the research laboratory of Syngaschem BV in the DIFFER building.
