Laser induced plasma

When a laser radiation is focused on a sample (solid, liquid and gas), its electromagnetic energy is transformed in to electronic excitation (free electron, plasmons). If the laser energy exceeds a characteristic threshold (depending on sample features and laser parameters), evaporation, atomization, and partial ionization of the sample will result. Laser induced plasma (LIP) is defined as the generation of a totally ionized gas, a plasma, that practically is a ‘gas’ of charged particles. Therefore a short-pulse high power laser beam focused onto a sample converts a finite volume of sample instantaneously into its vapor phase constituents in an expanding plasma cloud. The high electron density and the high temperature sustain a plasma that then will rapidly evolve through a series of kinetic mechanisms. The study of the temporal and spatial evolution of LIP in different environments by the spectroscopic techniquesleads to the required knowledge useful for a wide range of application fields (i.e. chemical analysis, nanoparticles and nanostructures production).

Alessandro Polini, si aggiudica l'LushPrize2018

Berlino, 16 novembre 2018 

Alessandro Polini , giovane ricercatore presso l’Istituto di Nanotecnologia del Consiglio nazionale delle ricerche (Cnr-Nanotec) di Lecce, si è aggiudicato il Lush Prize 2018 categoria 'Giovani ricercatori', il premio che incoraggia le idee che promuovono la sperimentazione non animale.

Il giovane salentino ha visto così gratificare il suo studio basato sull’utilizzo di modelli 'organ-on-a-chip' altamente sofisticati per capire i meccanismi patologici alla base della Sclerosi Laterale Amiotrofica (SLA). Formatosi nel campo delle biotecnologie mediche, bioingegneria e nanotecnologie, anche con importanti esperienze internazionali -dal Lawrence Berkeley National Laboratory in California all'Harvard Medical School in Massachusetts per approdare poi alla Radboud University in Olanda- Alessandro Polini è rientrato in Italia per proseguire gli studi relativi ai sistemi 'organ-on-a-chip' grazie alla piattaforma tecnologica TecnoMED, il 'Tecnopolo di nanotecnologia e fotonica per la medicina di precisione' nato presso il Cnr-Nanotec di Lecce da un progetto finanziato da Regione Puglia, Cnr e Miur...
