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.

Tristan Tentrup 'High-dimensional quantum communication' This thesis is about the further development of high-dimensional spatial-alphabet quantum communications. ‘Especially in encrypted video communication the quantum key generation rate is the main bottleneck,’ Tristan Tentrup explains the topical relevance of his PhD work. Jordi Moreno 'Energy generation from salinity gradients with reverse electrodialysis, fouling management and process design' In this thesis Reverse Electrodialysis (RED) is central. A RED stack comprises of alternating series of cation exchange membranes (CEMs) and anion exchange membranes (AEMs), with seawater and river water compartments between these membranes. Pieter Westerik 'microfabrication for solar-to-hydrogen devices' In this thesis microfabrication techniques for the development of solar-to-hydrogen devices were studied. Anupam Pandey 'Mechanics at soft interfaces' In this thesis the interaction of soft interfaces with liquid drops, solid particles and liquid flows is explored. ‘This led to some new, interesting phenomena,’ says Anupam Pandey. ‘We also brought a new perspective to the classical creasing instability of a compressed soft solid, where the interface folds onto itself and creates a self-contact.’ Terica Sinclair 'Virus control by enhanced physical seperation' In this thesis microfiltration (MF) membranes are studied with a focus on the removal of viral pathogens. Evelien Maaskant 'Mix and Match - New monomers for interfacial polymerization' In this thesis the synthesis of thin films by interfacial polymerization is studied. Interfacial polymerization is a very versatile technique to allow for the production of thin, defect-free films in a localized manner. Seyed Mehran Abtahi Foroushani 'Towards tertiary micropollutants removal, by bio-augmented moving bed biofilm reactors an nanofiltration' In this thesis, reducing the release of emerging micropollutants (MPs) into the surface water, is the center of focus. ‘The potential risk of MPs, constantly discharged from municipal wastewater treatment plants, is now under active evaluation among researchers worldwide.,’ Seyed Mehran Abtahi Foroushani says. Vishal Ahuja 'Hydrodynamically coupled Brownian dynamics simulations for flow of non-newtonian fluids' In this PhD thesis, a novel computational technique called Hydrodynamically Coupled Brownian Dynamics (HCBD) was developed. It can be used to couple any Brownian dynamics based polymer model, with a fluid model such as Smoothed Particle Hydrodynamics. 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.’
