Research topics:

Laser texturing of metal surfaces: A method has been developed for the generation of nanoscale periodic structures called Laser Induced Periodic Surface Structures (LIPSS) that provide certain surface functionalities. Specifically, application of these nanometric structures has been shown to prevent the growth of bacterial colonies on machine components in the agri-food industry. This application was addressed in the European project TRESCLEAN and the POR-FESR 2014-2020 regional project.

Surface metrology: In the context of topography analysis via scanning probe microscopy and optical profilometry, methods have been developed for detecting the density of peaks generated by technologies exploiting energy intensification. An algorithm has been developed that can model the behaviour of deformable bodies such as bacterial cells in the proximity of a rough surface.

Active projects:

TRESCLEAN "High throughput laser texturing of self-cleaning and antibacterial surfaces" funded by the European Commission under the Call H2020-ICT-2015. Beneficiary: University of Parma.

Objective: Development of optical components and laser systems for large-scale production of highly aseptic metal components for the food industry. The research group at the University of Parma was responsible for the design of the surface morphology through the modulation of periodic structures induced by laser pulses with a duration of less than one picosecond, with specific reference to antibacterial properties, and their metrological and microbiological characterisation.

Project duration: 42 months starting 1 April 2016. The Consortium Agreement was approved by the University of Parma with REP. D.R.D. No. 126/2016 on 27/1/2016.

Total budget funded by the European Commission: € 3,364,000.

Activities: Scientific direction and coordination of the consortium comprising six partners: ALPhANOV-Institut d'Optique d'Aquitaine (Fr), University of Stuttgart (Ge), Ecor International (It), Raylase (Ge), Bosch / Siemens (Sp) and Modus ltd (UK). The research group was also responsible for WP2 (assigned budget € 563,000), as well as dissemination and project management as coordinator.
