Plasmas for aerospace

Numerical codes implementing kinetic, PIC, DSMC and fluid dynamic approaches and including advanced state-to-state chemical-physical models are used for the investigation of plasmas of interest for aerospace applications, with particular attention to the simulation of non-equilibrium conditions in planetary entry conditions, dusty plasmas and plasma propulsion systems.

Hypersonic Flows

The reliable prediction of thermal loads on a spacecraft thermal protection systems during an high-speed entry in the atmosphere of Earth and other planets requires proper consideration of the non-equilibrium character of the flow, taking into account the elementary processes of atomic and molecular excitation, dissociation and ionization induced by collisions with heavy particles and electrons, in the state-to-state approach, extended also to more complex molecules as CO2. Radiation emitted by excited species gives a further contribution to the vehicle heat load, determined by photon transport equation.
Different non-equilibrium phenomena can be observed in the first part of the atmosphere, in very rarefied conditions, where the mean free path of particles is very long, comparable with the vehicle dimensions, needing particle simulations (DSMC). Other problems are related to the control and stability of hypersonic intercontinental flights based on SCRAMJET engine. Surface dielectric barrier discharge (DBD) is a promising technique to avoid the use of mechanical actuators, not adequate for hypersonic flights. Particle and fluid simulations have been done for modelling DBD’s. Different approaches have been used to investigate geometries, ranging from homogeneous systems to 3D flows coupling self-consistently Boltzmann and Master Equations, Radiative Transfer Equation (RTE), Boundary Layer or Navier-Stokes Equations.

Space Plasmas

Plasma is the most diffuse matter state in the Universe, where conditions are often very extreme, from very low to very high density. This research line starting from fundamental aspects has different applications.

» Dusty Plasmas
The interaction of space dust in the surrounding plasma determines charging/growing dynamics and transport of dust grains. This research line deals with the dynamics of dust above airless body surfaces, rings and planetesimal formation.

» Nanoconfined Atoms and Molecules
Atomic species in high-density plasma, as met in star, are investigated by means of quantum theory. Modification of the atomic structure has relevant effects in thermodynamics and transport properties.

» Astrochemistry
The study concerns the chemical kinetics of the formation of the first molecules and the effect of the distribution of energy on the reaction mechanisms in space environment.

» Scientific space mission design
The advances in theoretical and numerical study of plasma turbulence require constant validation from in-situ observations. This calls for the progressive improvement and specific design of scientific space mission, that need to provide the observables necessary for the validation of the theory. NANOTEC_Rende actively participates in the design and realization of ESA and NASA space missions, such as ESA/THOR, ESA/Solar Orbiter and NASA/GRIPS.

Plasma for Space Propulsion

Electric thrusters (Hall-effect and helicon discharges) and plasma-assisted combustion (SCRAMJET) are important for space transportation (satellite guidance, orbit transfer and deep space exploration). Different numerical approaches (particle-based models and chemical kinetics) have been used to investigate non-equilibrium conditions typical of plasma propulsion systems.

Loretta del Mercato, si aggiudica  l'ERC STARTING GRANT 2017

uno dei bandi più competitivi a livello europeo.

Lecce, 6 settembre 2017 

Lo European Research Council, che promuove la ricerca di eccellenza in Europa, nei giorni scorsi ha reso noti i nomi dei 406 vincitori della selezione ERC STARTING GRANT 2017, il bando tra i più competitivi a livello internazionale.

Su 3085 progetti presentati, 406 i progetti selezionati a cui sono stati destinati i 605 i milioni di euro di investimento. 48 le nazioni di provenienza dei ricercatori, soltanto 17 gli Italiani che condurranno le loro ricerche nel nostro paese, tra cui Loretta del Mercato, ricercatrice dell'Istituto di Nanotecnologia del Consiglio Nazionale delle Ricerche di Lecce.

Un importante riconoscimento alla ricerca nel settore della medicina di precisione condotta presso il CNR NANOTEC, un indiscusso premio al talento della giovane ricercatrice che, a 38 anni e un contratto a tempo determinato, sarà a capo del progetto "Sensing cell-cell interaction heterogeneity in 3D tumor models: towards precision medicine – INTERCELLMED".

Il progetto, il cui obiettivo è affrontare uno dei problemi più spinosi della ricerca sul cancro, ovvero la difficoltà nel trasformare i risultati delle ricerche scientifiche in applicazioni cliniche per i pazienti e che vedrà coinvolto l'Istituto tumori "Giovanni Paolo II" di Bari, si propone di sviluppare nuovi modelli in vitro 3D di tumore del pancreas, alternativi ai modelli animali, ingegnerizzati con un set di sensori nanotecnologici che consentiranno di monitorare le interazioni delle cellule tumorali con il loro micorambiente, verificare l'appropriatezza delle terapie prima della somministrazione ai pazienti oncologici e quindi prevedere la risposta dei singoli pazienti ad una o più terapie antitumorali.

La realizzazione di queste piattaforme 3D multifunzionali consentirà di superare le evidenti differenze intercorrenti tra "modelli animali" ed esseri umani fornendo dati attendibili ed in tempi più rapidi rispetto ai dati ottenuti tramite lunghi e costosi procedimenti di sperimentazione sugli animali. Le tecnologie e i modelli sviluppati saranno estesi anche ad altre forme di tumori solidi nonché impiegati per studi nell'ambito della ingegneria tissutale e della medicina rigenerativa.
