The project aims to develop knowledge and a method to make a new bio-based material from lignin and cellulose extracted from the local Dutch agricultural and forestry biomass side streams and residual streams to enable 3D printing of building components for the building industry. It aims to provide the construction industry with "wood without trees".

The continuous monitoring of health indicators in biofluids such as sweat, saliva, blood, and urine has great potential for preventive medicine. Techniques that continuously monitor biomarkers still remain a major technological challenge. Recently, a concept of dynamic biosensing was published that is based on mediator particles. Such mediator particles exhibit rapid switching between a bound and unbound state during interaction with a probing structure to which they are connected through a molecular tether (like a balloon on a string). Although the concept of using mediator particles for dynamics biosensing is very promising, the used detection method is not a viable solution as it is not miniaturizable. We propose to use a photonic ring resonator (RR) or Mach-Zender interferometer (MZI) as the probing structure in combination with a highly miniaturizable readout scheme. In this project, we perform preliminary experiments to prove that this photonic approach can be used for the detection of the mediator particles tethered to the photonic waveguide. To bridge the gap with the practical application by health professionals, we will enrich the envisioned solution through OnePlanets OpenEd program. OpenEd aims to share technology and innovations (e.g. prototypes) with educational institutes (MBO, HBO) that want to further innovate their courses or work methods, such that current and future professionals are well prepared to work with new (digital) technologies. By presenting our use-case as a challenge to teachers, students and practitioners, OpenEd also allows enriching the use-case by involving (future) health professionals that can provide feedback on - or further investigation of - the practical application of our new technology from the health professionals perspective.

We recently invented a highly efficient continuous electrochemical ammonia synthesis process from gaseous nitric oxide. This project aims at demonstrating the technology under commercially-relevant conditions, evaluating economic viability and developing future solutions for decentralized, CO2 emission-free production process of ammonia which is the primary ingredient for fertilizers and a promising liquefiable chemical energy carrier. Effects of feed composition, materials/process stability and scale-up feasibility will be studied and a thorough techno-economic analysis will be performed.

The study is about metric and arithmetic properties of algorithms for continued fractions, which are used for approximating real numbers by rational numbers. The first part is on approximation coefficients of regular continued fractions. These coefficients indicate the quality of an approximation. The study is focused on examining properties of these coefficients. Next, I will study the recently introduced N-expansions, which in some ways have more attractive properties than regular expansions but may lack some other. Finally, I will focus on a/b-continued fractions, based on a recently developed algorithm for continued fractions.
