Graphene-nanostructure hybrid materials for advanced sensing applications


Combination of metallic nanostructures with graphene is envisioned to modify with accuracy and to confer extra functionality to the already extraordinary properties of graphene. Physical vapor deposition methods, such as magnetron sputtering or gas-phase aggregation techniques, are reliable methods to incorporate functional nanostructures. The gradual manipulation of the optical and electric properties in these hybrid materials is anticipated to give insight into the development of tunable touch, chemical and biosensors and other advanced electronic devices.

Mn-based rare-earth-free permanent magnetic nanostructured alloys


The so-called “rare-earth crisis” in the 2010’s re-ignited investigation in the search for new concepts in permanent magnetic materials design.  The key factor is that advanced fabrication and analysis methods with precision down to the nanoscale that combine composition and crystal structure control and optimization of the microstructure to manipulate the intrinsic magnetic properties of magnets (magnetization, exchange and magnetocrystalline anisotropy) or to enhance extrinsic magnetic features (remanence and coercivity) are now accessible. Thus, current strategies involve nanostructuring and control of crystal structure and composition to the nanoscale through metallurgical non-equilibrium processing techniques convey optimization of the magnetic properties or advantageous modification of the fabrication process of new magnets.

Magnetostructural nanomaterials


Magnetic materials presenting magnetostructural transitions are subject of intense study in the current days, due to their more than interesting properties, as well as to their potential applications in magnetic memory, caloric nd sensor devices. A very intereseting research pathway is the study of the magnetostructural transition of FeRh (AF-FM with simultaneous lattice expansion at around ambient temperatures) subjected to atomic substitution and nanostructuring effects. Results are providing exciting hints in order to develop nanomagnetic materials with tunable properties.
