NANOALLOY is a COST action in the domain of Materials, Physics and Nanosciences (MPNS). The COST website contains a page on this action under the code MP0903. Alloy nanoparticles (also known as nanoalloys) are multicomponent metallic particles in the 1-100 nm diameter range. Nanoalloys present very complex structures and properties, which crucially depend on their size, composition and chemical ordering, and which can therefore be tailored for specific and industrially relevant applications - as in data storage, optical devices and catalysis. Controlling and tailoring the properties of nanoalloys, and determining their phase diagrams, require the concerted effort of experiment and computer modelling. NANOALLOY brings together European experimental and theory/modelling research groups from universities and other research institutions to develop new methodologies for the growth, synthesis and characterization of nanoalloys, leading to new applications and materials.
This project is focused on the synthesis by induced electrodeposition of nanowires and nanotubes as multilayered structures consisting of cobalt alloys with refractory metals like Mo and W. Hereto the superfilling of nanopores present as arrays in anodized aluminium oxide (AAO), will be investigated in-depth. First proofs of principles have been recently achieved by the applicant. The background of the host institution on electrodeposition in micro-pores (e.g. vias used in microelectronics) and its modelling is a most important support to this project.
EXPECTED RESULTS AND OUTCOMES
- The electrodeposition of cobalt-based homogeneous and multilayered nanotubes and nanowires engulfed in anodized aluminium, and as free-standing products after release from anodized aluminium.
- Scientific insight on the role of electrochemical parameters on structural and functional properties of electrodeposited nanotubes and nanowires either engulfed or released from anodized aluminium.
- Mapping of the functionality of nanotubes and nanowires made of compositionally modulated layers in view of future applications in MEMs and NEMs technology as wear resistant and/or electro-magnetic materials."
