The management of schizophrenia is evolving towards a more comprehensive model based on functional recovery. concept recovery goes beyond clinical remission and encompasses multiple aspects the patient's life, making it difficult to settle definition develop reliable assessment criteria. In this consensus process panel experts in schizophrenia, we aimed provide useful insights its involvement practice research. After literature review scientific committee 8 members prepared 75-item...
We report a self-assembled metallo suprapolymer gel exhibiting remarkable self-healing features. The Ni2BTC gels result from the complexation of Ni2+ metal ions by tritopic ligand (bis-terpyridine cyclam) in dimethylformamide (DMF) and an annealing step at 50 °C for 24 hours. properties are characterized visual inspection, rheological impedance spectroscopy measurements: results compared with those fatty acid-based molecular organogel chosen as reference system. creep–recovery analysis uses...
