Welcome to the GEFRO group
Our group in Electrochemistry, Photochemistry and Organic Reactivity (GEFRO) from the Department of Chemistry of the UAB aims at studying and developing new processes and materials by means of photo- and electrochemical technologies. Based on the multidisciplinary background of our research team, we investigate a variety of processes and materials ranging from the electrosynthesis of organic compounds and the electroactivation of CO2 to the sustainable synthesis and processing of polymers as well as the preparation and characterization of smart molecules and (nano)materials. A number of different equipments and facilities are available in our laboratories to carry out this research, which is supported by both public and private funding.

Jaume Otaeguis’s paper on fluorescent data storage and encoding is now online in Advanced Functional Materials
Jaume Otaegui‘s first-author publication is now published in Advanced Functional Materials. In collaboration with Nanosfun (ICN2-BIST), in this work we describe a novel strategy for the fabrication of fluorescent 3D and 4D codes capable of high density and high security encryption data storage. Our approach makes use of microstructured dye-paraffin mixtures, with which pixel arrays can be prepared that exhibit stimuli-responsive and multicolor emission. Nice work, Jaume!

Kick-off meeting of Confeti
This week we celebrated the kick-off meeting of Confeti at UAB, an EIC Pathfinder Challenges project recently funded. Through the combined effort of an international consortium led by Dr. Gonzalo Guirado, Confeti aims at developing a lab-scale validated autonomous technology to capture and photo-electrochemically convert CO2 and N2 directly from air or flue gases to urea, which will be produced and delivered in situ in the agricultural fields. To start the project, researchers from all the partners of the consortium gathered together at UAB campus in November 7th and 8th (UAB, CSIC-IMB, CNRS, Université Paul Sabatier Toulouse III, Universiteit Antwerpen, Universitá di Pisa, CIEMAT, Iowa State University and Arkyne Technologies SL).

Jaume Otaegui’s paper on smart windows is now online in Chemical Engineering Journal
Jaume Otaegui‘s first-author publication is now online in Chemical Engineering Journal. In collaboration with Nanosfun (ICN2-BIST), in this work we describe a novel methodology for the preparation of smart windows based on the use of paraffin-polymer nanocomposites that show large modulation of light transparency upon thermal, photothermal and electrothermal heating. As a result, these materials exhibit efficient regulation of solar heating indoors for different weather conditions. This, in combination with their low cost, facile fabrication, ample tunability and high photostability and flexibility, makes our technology very appealing for the smart glass market. Nice work, Jaume!
