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.
