Transport coefficients for Planetary Atmospheres

Transport coefficients (thermal conductivity λ, viscosity η and electrical conductivity σe) for plasmas generated in the impact of space vehicles on different planetary atmospheres (Earth, Jupiter, Mars), have been derived, in the framework of the Chapman Enskog theory, considering a high-order approximation and including also minor species. The core of the calculation is represented by the characterization of binary interactions, i.e. the derivation of collision integrals, describing the microscopic dynamics. The phenomenological approach has been proposed and validated for a number of different systems, that is based on modeling the average interparticle interaction with a phenomenological potential, whose parameters can be estimated through correlation formulas from physical properties of the collisional partners. Moreover a novel efficient algorithm has been implemented based on fractal integration.

Technology transfer

The joint research activity with Antonio D’Angola (Università della Basilicata) has led to the construction of a web-access computational tool EquilTheta, that calculates chemical equilibrium product concentrations, thermodynamic and transport properties for a given mixture in wide temperature and pressure ranges, and is the focus of a business plan for the creation of a CNR-UniBAS spin-off.

TERAMETANANO - International Conference on Terahertz Emission, Metamaterials and Nanophotonics

TERAMETANANO - IV ed.

Castello Carlo V, Lecce 27 -31 Maggio 2019

The IV edition of TERAMETANANO, the International Conference on Terahertz Emission, Metamaterials and Nanophotonics, will take place in Lecce (Italy) from 27 to 31 of May 2019 in the 16th-century Castle of Charles V   with two special nights that will be held in an original Theatre of Roman period.

 

TERAMETANANO is an annual conference that gather physicists studying a wide variety of phenomena in the areas of nano-structuresnano-photonics and meta-materials, with special attention to the coupling between light and matter and in a broad range of wavelengths, going from the visible up to the terahertz.

 

Al via la fase 2 del Tecnopolo per la medicina di precisione

Firmata convenzione tra Regione, Università e Cnr per avvio seconda fase del Tecnopolo

Bari, 27 novembre 2018 

Sottoscritto stamane l’accordo tra Regione PugliaCnr Consiglio nazionale delle ricerche, Irccs Giovanni Paolo II di Bari e Università di Bari per l’avvio della seconda fase del Tecnopolo per la Medicina di Precisione. Sede del tecnopolo, il CnrNanotec.

“La sfida della medicina moderna è tradurre nella pratica clinica gli enormi progressi compiuti dalla scienza e dalla tecnologia. In questo contesto le nanotecnologie, focalizzate sull’indagine e sulla manipolazione della materia a livello nanometrico-molecolare, si presentano come uno strumento potentissimo al servizio della medicina di precisione, la nuova frontiera che punta allo sviluppo di trattamenti personalizzati per il singolo paziente”, afferma  Giuseppe Gigli, direttore di Cnr Nanotec e coordinatore del Tecnopolo.

Colloidal nanocrystals (NCs) are very promising materials for photovoltaic applications since they can absorb most of the sunlight radiation, they can be synthesized in the solution phase and may coated on flexible substrates, retaining the broadband absorption and superior transport properties of traditional photovoltaic semiconductors.
