In this research paper, STiBNite ESRs Marco Franceschini and Martina Crosta (UNIVIE) present the synthesis and the properties of a series of BN-doped molecular ribbons. The BN-graphenoids in this study show systematic red-shift of their UV−vis absorption and emission spectra, as well as a decrease in their oxidation potential, upon elongation of the fused aromatic backbone. In addition, the ribbons’ emission shows a Thermally-Activated Delayed Fluorescence (TADF) component. All these properties are highly desirable features to engineer p-type organic semiconductors.

In this collaborative work, Anna Voronova (Univ. Lille) and STiBNite ESR Diego Jaramillo (device fabrication, UCLouvain) present the delivery of an angiotensin-converting enzyme (ACE) inhibitor, ramipril, using an electrothermal actuator based on a gold nanowire array to increase the transdermal ramipril flux. Using rats as in vivo model, systolic and diastolic blood pressure were monitored, while heat activation in the electrothermal actuator provided full drug delivery. The full paper can be found here.

In this research paper, STiBNite ESR Laura Caputo, using first-principles (ab initio) techniques, investigates the periodic doping of graphene with borazine-like rings. The theoretical calculations show that the properties are sensitive to the doping pattern and doping concentration, and therefore these materials could be interesting candidates for optoelectronic applications. The full paper can be found here.

In this collaborative work where the STiBNite ESR Sena Tömekçe (TUM) is involved, Marc G. Cuxart presents the fabrication of B-doped graphene by chemical vapor deposition (CVD), using borane tetrahydrofuran on iridium substrate, which templates the segregation of boron substitutional atoms. The resulting material has been characterized by scanning tunneling microscopy/spectroscopy (STM/STS), x-ray photoelectron spectroscopy (XPS), angle-resolved photoemission spectroscopy (ARPES) and density functional theory (DFT) calculations. The full paper can be found here.

In this review, STiBNite ESR Luca Cavinato (TUM) presents an extensive overview of emerging bio-derived materials suitable for organic solar cells, dye-sensitized solar cells and perovskite solar cells. Their production, handling, characterization, and implementation as bio-hybrid components, such as substrates, electrodes, photoactive layers, carrier transporters, light-trapping layers and sealant films, are critically discussed. The full paper can be found here.

In this collaborative work, Deborah Romito (UNIVIE), together with STiBNite ESRs Luca Cavinato (device fabrication, TUM) and Laura Caputo (theoretical calculations, UCLouvain), demonstrates how the use of chalcogen-bonded molecules, in light-emitting electrochemical cells (LECs), prolongs the device lifespan. The full paper can be found here.

In this research paper, STiBNite ESR Luca Cavinato (TUM) presents a new family of green electrolytes in light-emitting electrochemical cells (LECs). Self-stable and highly performing LECs are achieved by combining novel biogenic cellulose-based electrolytes and archetypical emitters (i.e., conjugated polymers (CPs) and ionic transition metal complexes). For the first time in the field, green electrolytes do not jeopardize device performance. The full paper can be found here.
