Rapid investigation of geometric effects on charge transport in electrodialysis, Anne Benneker (SFI)

Investigation of the effect of geometry on charge transport in electrodialysis is extremely important as it can strongly influence performance. In this research, a microfluidic electrodialysis platform using charged hydrogels was developed for rapid investigation of the role of membrane geometry on charge transport.

Hydrogen production from solar energy based on a microporous silicon membrane device, Pieter Westerik (MCS)

Our fossil fuel based economy is not future proof. They cause pollution and climate change, and reserves are depleting at an alarming rate. Solar energy is a promising renewable alternative, but needs energy storage to bridge nights and winters. A promising technology is hydrogen generation, and for that purpose here we present an integrated water splitting device architecture.

Using Magnetophoresis to Sort FCC Particles: The Relation between Activity and Fe Distribution, Miguel Solsona (BIOS)

Fluid catalytic cracking (FCC) particles are responsible for cutting down long chain hydrocarbons into smaller and more useful molecules, however, they deactivate due to Fe, Ni and V accumulation coming from the feedstock. This approach aims at sorting FCC particles by their Fe content using magnetic fields & microfluidics and investigate their activity and Fe distribution.

An evaporating Ouzo droplet, Huanshu Tan (POF)

Evaporating liquid droplets are omnipresent in nature and technology. Here we show that the evaporation of such ternary mixtures can trigger a phase transition and the nucleation of microdroplets of one of the components of the mixture. As a model system, we pick a sessile Ouzo droplet and reveal and theoretically explain its four life phases.
