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.

The production of hydrogen by solar energy is an attractive technique to realize global renewable energy supply. The photoinduced water splitting into hydrogen and oxygen by the direct use of sunlight is an ideal, renewable method of hydrogen production that integrates solar energy collection and water electrolysis into a single photoelectrode. Although the concept is attractive to produce sustainable fuel, the suitable electrode material (performance, stability and low cost) is yet to be found.

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.
