PhD Graduates

To give an impression of what it is to be a PhD student at MESA+, we interview all finishing students and ask them to share their experiences. An abstract of their thesis’s can also be found, so that it can supply an idea of the scientific part of their work, while the interviews are intended to give an impression of the working environment of a PhD student at MESA+. To view more interviews, select a year in the directory to the left.

Zinaida Kostiuchenko ’Mass flow in electrochemical nanofluidic detectors’ In this thesis nanogap devices were studied using amplification through redox cyling of analyte molecules between two parallel, closely spaced electrodes. Dennis Alveringh ‘Integrated throughflow mechanical microfluidic sensors’ In this thesis are described: novel designs, fabrication methods and experiments of microfluidic sensors that use a mechanical transduction principle. ‘They can be integrated, throughflow, with other sensors on a single chip,’ says Dennis Alveringh. Rogier van den Bos ‘Hydrogen induced blister formation in heterogeneous structures’ In this thesis blister formation in multilayer systems was central. ‘We studied how stabilized blisters are formed in nanometer thick molybdenum/silicium multilayers, under the building up of hydrogen pressure,’ Rogier van den Bos says. ‘A model description of the growth and stability of blisters by elastic deformation within the multilayers was developed.’ Anne Benneker ‘From small to big: Ion transport at interfaces’ In this work, ion transport at charge selective interfaces is investigated. ‘This is important in a multitude of technologies,’ says Anne Benneker. ‘Electrochemical cells, such as fuel cells, and electrodialysis both serve as good examples.’ Timon Rijnaarts ‘The role of membranes in the use of natural salinity gradients for reverse electrodialysis' In this thesis reverse electrodialysis (RED) is central in which energy is harvested from a salinity gradient. For RED, two streams with a difference in salinity are used in combination with ion exchange membranes. Jeroen Huijben ‘Interfacial phenomena in atomically engineered LaAlO3/SrTiO3 heterostructures’ In this thesis a complex oxide is central. These type of materials are interesting as they exhibit spectacular phenomena including: colossal magnetoresistance, high transition temperature superconductivity, ferromagnetism and ferroelectricity. Celestine Lawrence ‘Evolving networks to have intelligence realized at nanoscale (ENTHIRAN)’ In this thesis the shrinking down of hardware feature sizes is the central base for research. ‘This can lead to packing densities beyond the scope of human design,’ Celestine Lawrence says. ‘Going beyond current CMOS technology, however, involves imperfections and other unintended physical effects. Alexander Milbrat ‘Electrochemical coating of micro-structured silicon for photoelectrochemical water splitting’ In this thesis the focus is on the development of materials for photoelectrochemical devices, applicable in solar-driven hydrogen generation from water splitting. Gulistan Kocer ‘Cell-instructive biointerfaces with dynamic complexity’ In this thesis chemical approaches inspired by the extracellular environment are explored. ‘We aim to fabricate cell-instructive biointerfaces,’ says Gulistan Koçer. ‘Light-responsive liquid crystal polymer networks (LCNs) and supported lipid bilayers (SLBs) are presented and discussed, with an emphasis on investigating stem cell behaviour.’ Yao Lu ’Hypersonic poration of membranes: from triggered release and encapsulation to drug delivery’ In this thesis hypersonic poration has been applied, to induce reversible membrane disruption in different assembled systems, such as: supported lipid bilayer (SLB), giant unilamellar vesicles (GUVs), polymer-shelled vesicles (PSVs) and cells. Marise Gielen ‘Splashing drops’ In this thesis, the focus is on substrate properties influencing the splashing behaviour of impacting drops. ‘The PhD project was a collaboration between NWO and ASML,’ says Marise Gielen. ‘In the extreme ultraviolet (EUV) source chamber, liquid tin debris impact is causing a lot of contamination.
