This work presents a systematic and rational approach to the synthesis of previously reported as well as novel tetra- and di- ortho-borylated perylene, perylenediimide, and perylenemonoimide scaffolds. Through optimization of reaction conditions, employing [Ir(OMe)(COD)]₂ as a catalyst and the suitable ligands, efficient tetraborylation and regioselective diborylations were achieved. Additionally, the reaction times were reduced from days to hours under microwave irradiation, rendering this methodology a practical and scalable route for the ortho-functionalization of perylene derivatives.

Our work demonstrates that alterations in post-transcriptional gene expression because of miRNAs dysregulation might represent an endogenous mechanism by which insulin response in the subcutaneous fat depot is already affected at middle age. Importantly, caloric restriction could prevent this modulation, demonstrating that certain miRNAs could constitute potential biomarkers of age-related metabolic alterations.

Oxidative steam reforming allows higher energy efficiency and lowers coke deposition compared to traditional steam reforming. In this work, CeO2-based supports have been prepared with Ni as the active phase, and they were tested in the oxidative steam reforming of acetic acid. The in-fluence of the O2/AcOH molar ratio (0 - 0.3) has been evaluated over Ni/CeO2. The results stated that by increasing oxygen content in the feeding mixture, acetic acid conversion increases, too with a decrease in coke deposition, and hydrogen yield. To have a proper balance between the acetic acid conversion and the hydrogen yield an O2/AcOH molar ratio of 0.075 was selected to study the catalytic performance of Ni catalysts over different supports: commercial CeO2, a novel mesostructured CeO2, and CeO2-SBA-15. Due to higher Ni dispersion over the support, the mesostructured catalysts allowed higher acetic acid conversion and hydrogen yield compared to the non-porous Ni/CeO2. The best catalytic performance and the lowest coke formation (120.6 mgcoke·gcat 1·h 1), were obtained with the mesostructured Ni/CeO2. This sample reached almost complete conversion (> 97%) at 500 °C, maintaining the hydrogen yield over 51.5% after 5 h TOS, being close to the predicted value by the thermodynamic equilibrium due to the synergistic co-ordination between Ni and CeO2 particles.

The equipment was purchased with the support of the grant RYC2021-033499-I, with the objetive of providing solar irradiance measurements, which are required to evaluate the performance of solar technologies. It was intalled in Getafe's UPM premises during the measurement campaign (one year).
