Fuel Cells and Water Remediation

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

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.
