A study of the magnetic and electrochemical properties of a TEMPO-substituted disulfide diradical in three different environments was carried out: in solution, in the crystal, and as a self-assembled monolayer (SAM) on an Au(111) substrate, and the relationship between them was explored. In solution, this flexible diradical shows a strong spin-exchange interaction between the two nitroxide functions that depends on the temperature and solvent. Structural, dynamic, and thermodynamic information has been extracted from the EPR spectra of this dinitroxide. The magnetic interactions in the crystal include intra- and intermolecular contributions, which have been studied separately and shown to be antiferromagnetic in both cases. Finally, we demonstrate that both the magnetic and electrochemical properties are preserved upon chemisorption of the diradical on a gold surface. The resulting SAM displayed anisotropic magnetic properties, and angle-resolved EPR spectra of the monocrystal allowed a rough determination of the orientation of the molecules in the SAM.

The potential application of molecular switches as active elements in information storage has been demonstrated through numerous works. Importantly, such switching capabilities have also been reported for self-assembled monolayers (SAMs). SAMs of electroactive molecules have recently been exploited as electrochemical switches. Typically, the state of these switches could be read out through their optical and/or magnetic response. These output reading processes are difficult to integrate into devices, and furthermore, there is a need to use liquid environments for switching the redox-active molecular systems. In this work, both of these challenges were overcome by using an ionic gel as the electrolyte medium, which led to an unprecedented solid-state device based on a single molecular layer. Moreover, electrochemical impedance has been successfully exploited as the output of the system.
The OISensing project has won the prize from Ideas Generation Program. This project has developed a BL (Bi-Layer) film made of a new material completely organic and sensitive to infrared radiation. The characteristics of this material make it optimal for low-cost sensors used in the objects detection on large distances, with lower consumption and without need of refrigeration. It has been driven by researchers Dr. Victor Lebedev and Prof. Jaume Veciana from the NANOMOL group, Dr. Ana Magrasó from the Catalan Institute of Nanoscience and Nanotechnology (ICN2) and Fredi Fernández, a specialist in sales and marketing.
Sensors that developed based on BL Films have special interest for using them in areas such as surveillance, safety and industrial process control. Specifically, they use drones to carry out risk prevention tasks, rescue and fire control. The sensors have higher sensitivity, 70 times lower price than the currently used materials and no require complex electronics to optimize energy consumption. The sensors also are bringing an environmental and safety benefits for manufacturers, since the material (full organic) is not composed of toxic elements that are typically required in today's detectors.
The prize consists of 1,500 euros and three months of incubation in the Eureka building.

"Nanomedicine" is a new word, but it is heard more and more. It is based on the administration of drugs by very small particles. They act directly on the specific site of the body, hence they are more effective. Using this methodology, Catalan researchers have found a new way to treat ulcers as the so-called "diabetic foot".
On June 9th 2015, 16th Symposium on rare diseases was held at the Institute of Catalan Studies, in which the results of 20 research projects funded by TV3 Marathon Foundation in its edition of 2009 were presented.
At the end of the ceremony, Dr. Gabriel Capellà, coordinator of the Scientific Advisory Board of the Foundation, mentioned five outstanding results from all developed projects. Among them, he spoke about the nanoconjugate developed by the NANOFABRY project through the collaboration of the CIBER-BBN groups headed by Dr. Simó Schwartz (VHIR), Prof Jaume Veciana and Dr. Nora Ventosa (Nanomol, CSIC), Dr. Miriam Royo (PCB-UB), and Dr. Pepe Corchero (IBB-UAB) for the treatment of the Fabry’s rare disease. This nanoconjugate is based on unilamellar lipid vesicles, or nanoliposomes, carrying the alpha-galactosidase enzyme as part of an enzyme replacement therapy for the Fabry’s disease. Dr. Capellà highlighted the submission and license of a patent protecting this nanoconjugate, recently licensed to the company Biopraxis Research, together with efforts done by the researchers to bring it to a regulatory pre-clinical stage, and the additional funding achieved by means of two new competitive projects, Lipocell and Terarmet, achieved by the same consortium.
Prof. Jaume Veciana has been named Scientific Director of the Singular Scientific Technological Infrastructures NANBIOSIS. This is one of the 29 ICTS which has been recently recognized by the Spanish Government (MINECO) comprising different units of the Biomedical Research Center in Bioingeneering, Biomaterials and Nanomedicine (CIBER-BBN) and the Centre for Minimal Invasive Surgery Jesus Uson (CCMIJU).NANBIOSIS provides a wide range of services for the production and characterization of nanomaterials, biomaterials and biomedical devices. This ICTS operates through a single contact point model and is organized into five platforms coordinating 27 service units that belong to CIBER-BBN and CCMIJU and that are distributed throughout the Spanish State (Alava, Badajoz, Barcelona , Caceres, Madrid, Valencia and Zaragoza) which receive support from more than 800 researchers from many different fields and with multidisciplinary experiences.
