Fuel Cells and Water Remediation

The main issue in this field is in fact the necessity of reducing the amount of precious metal catalyst and of finding protonic exchange polymeric membrane alternative to expensive NAFION. Fuel Cells for portable applications can take advantage from dry plasma technologies

Over the last decade, heterogeneuos photocatalysis has shown tremendous promise for the effective degradation of organic pollutants in water. Recently, immobilization of photocatalyst (e.g., TiO2 and ZnO) nanopowders on suitable substrates has attracted growing interest because it eliminates costly post-treatment separation processes and allows multiple catalyst recycling.

Oil/water separation materials have received considerable attention in recent years because of environmental problems associated with oily wastewater and oil spills.

Electrocatalytic layers

High performance electrocatalytic hydrocarbon thin films containing Pt nano-clusters can be deposited by simultaneous plasma polymerization of a monomer and sputtering of a Pt target. The proposed synthetic approach largely simplifies the PEMFC electrocatalyst fabrication process with respect to conventional methods.

The strategy carried out in our lab consists in a one-step simultaneous metal sputtering and plasma polymerization from a suitable monomer forming the embedding matrix. This approach allows for choosing the metal catalyst/or oxide independent from the matrix, which limit aggregation of the catalyst detrimental for eletrocatalyst performance

Protonic Membrane layers

Proton exchange membranes for fuel cells are typically made of a perfluorinated polymer matrix bearing phosphonic acid (–PO3H) or carboxylic acid (–COOH), or more often, sulfonic acid (–SO3H). The role of the electrolyte membrane in the fuel cell is to provide the transport of protons from the anode where the protons are produced, to the cathode where they are consumed by reduction with oxygen into water. It is essential to miniaturize conventional fuel cells components for portable devices. deposition from vapor phase, as PECVD or iCVD is advantageous since are dry processes compatible with microelectronic miniaturization

Photocatalytic degradation of organic pollutants

The research is focused on the atmospheric plasma deposition of thin films containing photocatalyst nanoparticles and characterized by high photocatalytic activity and recyclability.Thin films containing TiO2 and ZnO nanoparticles are deposited on different substrates by aerosol-assisted process in which a dispersion of preformed nanoparticles in a suitable solvent are in injected in aerosol form in an atmospheric cold plasma

Oil/water separation

The research is focused on the optimization of unique atmospheric plasma processes for the preparation of novel filtration or absorbing materials exhibiting opposite wettability behavior towards water and oil and consequently suitable for the effective separation of oil from water through selective filtration or absorption, respectively. Preparation of filtration materials for oil/water separation by atmospheric pressure plasma deposition of superhydrophobic/superoleophilic coatings on different substrates, such as fabrics, meshes, membranes.

Optimization of unique atmospheric plasma processes able to modify the outer and inner surfaces of porous absorbent materials, such as polymeric sponges, to achieve simultaneous superhydrophobic/superoleophilic properties

TERAMETANANO - International Conference on Terahertz Emission, Metamaterials and Nanophotonics

TERAMETANANO - IV ed.

 

Castello Carlo V, Lecce 27 -31 Maggio 2018

 

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.

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...
