Chemical synthesis of nanostructured oxides.
In this lab sol-gel, wet- and dry- syntheses are performed to prepare nanowires, nanoparticles, star-shaped and mutipods of oxides (mainly zinc oxide, silica, alumina) and metals (gold and silver). In particular the chemical lab is equipped for the synthesis of nanoscopic particles, wires, tubes and powders. The synthesis of the materials can be performed not only with conventional sol-gel chemistry, but also in protected atmosphere with a Schlenk-line or in a glove dry-box in nitrogen atmosphere. Autoclave for hydrothermal synthesis, anodic oxidation chamber, ultrasound bath, microwave, spin-coating, and thermostatic chamber for low temperature synthesis are also available for the material preparations.
Preparation and characterization of nanostructured materials.
The sample preparation and characterization it is performed with an UV-Vis lamp for photopolymerization purposes and a glove dry-box in nitrogen for the sample handling and synthesis in protected atmosphere. A polishing machine is also available for the surface grinding and polishing. Porous materials and nanosized powders can be characterized in this lab with a nitrogen sorption apparatus (Quadrasorb Quantachrome). Information like the specific surface area, the pore volume and pore size of the materials down to 2-3 nm in diameter can be easily obtained, measuring up to 4 samples in parallel. Supercritical CO2 dryer used for separating liquid form solid samples.
Polymeric nanocomposite synthesis for resistive hysteresis applications
In this lab synthesis of polymeric nanocomposites for resistive hysteresis applications is performed. In-situ and ex-situ nanoparticle synthesis is carried out by several techniques such as thermal, chemical or photo reduction of metal precursors. These materials are then used as fillers for the preparation of thermoplastics or thermosets nanocomposites by different methods such as spin casting, inkjet printing and photocuring. Resulting devices are exploited for their neuromorphic properties, in particular resistive hysteresis and resistive plasticity, to fabricate the logics of the future.
