In this project, solar concentrating power production systems and technologies are developed. The focus is on new innovations to bring this solar technology closer to commercialisation. A new type of concentrator, the so-called beam-down 2-stage concentrator, has been developed. It can be equipped with an integrated thermal (high-temperature) storage to provide dispatchable power operation. Up to 40% solar conversion efficiency can be reached.

VitalSens is a joint research project with the main goal of designing a smart, cost effective and scale-able personalized biomedical remote monitoring health platform. Printable wireless electronic sensors for continuous ECG monitoring are designed. Further, the ECG recordings are stored in a cloud storage. We then proceed by developing a computational engine which processes the physiological measurements and provide automated event detection for cardiovascular diseases (CVDs). The primary focus is to create an intelligent processing system which is adaptive to the patient ECG recording.

We aim at elucidating how plants acquire and use information about their abiotic and biotic environment. Perception of visible and ultraviolet regions of the daylight spectrum and the acclimation responses triggered by these cues are the main focus of our current research. Understanding cross-acclimtaion mechanisms can be used to develop new environmentally-friendly crop management strategies based on environmental cues, such as the light spectrum and/or temperature, replacing applications of chemical growth regulators and of some pesticides. Another application is enhancement of post-harvest shelf life of cut flowers, and leafy vegetables.

Global observations show that many high-elevation treelines are not advancing in spite of climatic warming. In this project, we aim to gain in-depth insight into the future of Andean treeline forests in a changing climate by predicting their persistence and upslope advance. This will be done by modelling potential microrefugial areas for treeline forests (suitable sites for tree growth in long-term) based on microtopography and current and future climate.

With the aim of achieving a more sustainable world, a number of efforts are currently oriented to replace synthetic polymer with the use of natural analogues, in order to obtain different materials. The objective of this project is to study in detail the characteristics of complexes formed by two different natural polyelectrolytes, such as chitosan and xylan. The research plan includes the study of the effect of the order of polyelectrolyte addition, relation of charge between them as well as the impact of the ionic strength and pH of the media in the external charge of the resulting complex. By reaching a better understanding of the condition of formation of these complexes, it is expected to widen the possibility of use of recycled, unbleached fibres in applications such as the manufacture of high quality packaging papers, and on the other hand, to manufacture films with excellent mechanical properties, of potential use in food packaging.
