Abstract:

We propose a methodology for the improvement of fabrication technology for the positive electrodes used as components in the lead-acid batteries produced at sc rombat sa . The final goal of our consortium is to improve the current technology used by industrial partner for fabrication of the batteries to be used for start-and-stop automobiles (i.e . To satisfy the j240 – sae and en 50342-6 quality tests) . The proposed approach is designed for the optimization of the scientific and technological steps involved in the fabrication of positive electrodes . It integrates the fundamental knowledge obtained from ab initio calculations, synthesis of new chemical compounds, fabrication of new alloys and structural characterization of the materials used to fabricate the electrode, at both nanoscopic and mesoscopic scale . The key element for the integration of all these activities is the fabrication and characterization of functional prototypes by the industrial partner.
The main problem to be solved is to control the corrosion of the positive electrode during the charge-discharge cycles, imposed by the requests of the start-and-stop technology . The solutions proposed by our consortium are: (i) fabrication of new alloys to be used for the production of the metallic grid that support for the active mass of the electrode (ii) improving the fabrication technology of the metallic grid (iii) improving the electrochemical properties of the active mass by new fabrication technology and by the use of new additives to the active mass. We note here that for the negative electrode as well as for the electrolyte the standard products fabricated by sc rombat sa will be used . The project’s goal will be achieved by using a feed-back loop: the design of materials and the fabrication steps involved by each prototype will be refined by successive fabrication of the prototypes that will gradually incorporate the information produced by each partner . At each step of our methodology the full characterization of the electrochemical and structural properties of the materials and prototypes already fabricated will be used as starting point for further refinement of the fabrication technology . A continuous exchange of data between the research Institutes and the industrial partner is foreseen for the whole duration of the project . This will allow us to tune the results obtained in the laboratory with those produced in industrial conditions . At project’s term we will discuss the technological steps needed for the implementation of the results by using the infrastructure available at sc rombat sa.

Abstract:

Immunological methods such as enzyme linked immunosorbent assay (ELISA) are increasingly becoming important for pesticides residual analysis due to the high specificity of detecting molecules like antibodies. These immunoassay methods are highly specific, sensitive (nanogram or picogram) and accuracy for the detection of low molecular weight contaminants presents in our environment. ELISA is a technique based on the ability of non-labeled antigen (e.g. pesticide) in a specific volume of standard solution or in an unknown sample to compete with a fixed of amount of enzymatic labeled antigen for a limited number of binding sites of a specific binding antibody protein. The objective of the project is to develop a new and innovative immunochemical technique based on functionalized nanoparticles, homogenous enzyme linked immunosorbent assay (HnELISA) technique for detection of pesticide contaminant 2,4-dichlorophenoxyacetic acid (2,4D) from alimentary and environmental samples. 2,4D is one of the most used herbicide in agriculture to control and destroy of the weeds that can affect agricultural crops. The remanence of this organochlorurate compound in alimentary products, transfer and contamination of ground water in the areas where this pesticide is used require the analysis of this chemical in order to establish the contamination level of the alimentary products and the environmental factors (water, soil).
The objective of the project is to develop an immunoassay technique with improved qualities in comparison with traditionally ELISA technique existed on the market for detection of pesticide contaminants from alimentary and environmental factors. Qualitative characteristics as sensitivity, accuracy, stability of the nanoimmunosorbent and low cost per assay are finally taken in account. Development of HnELISA technique would have practical application in monitoring of the pesticide contaminant 2,4D from alimentary and environmental samples.

Abstract:

Development of nanostructures capable of detecting and separating individual molecules and ions has become an important field of research. Particularly, protein-based nanostructures are attractive due to their ability for tunable molecular recognition and ease of chemical modification, which are extremely important factors on various applications. In this project, self-assembly functionalization will be approached, aimed at providing an efficient design for molecular recognition, ion sensing and separation, through new host-guest chemical methodologies, bio-nanofabrication and physicochemical manipulations methods. New crown ether type macrocycles, functionalized cyclodextrins and cyclic peptides will be engineered to work as specific molecular adaptors for the -hemolysin protein, giving rise to hybrid molecular superstructures possessing ion sensing and selectivity properties. The size and functionality of the macrocycles are targeted to ensure the anchorage in the pores and the selectivity of specific host-guest complexation processes. A surface detector array device suitable for use with a biosensor is envisioned, through ink printing nanotechnologies. The device architecture will be formed of a substrate having a surface defining a plurality of distinct bilayer-compatible surface regions separated by one or more bilayer barrier regions. Custom designed nanoscale bilayers containing selected receptors through cyclodextrins derivatives and macrocyclic peptides, self-assembled on different micro-nano arrays surfaces (polymers, Au or Si) will be fabricated. Further engineering of such functionalized nanomaterials based on molecular recognition and host-guest methodologies, in conjunction with flexible and mechanically robust enough substrate platforms, have the great potential for applications such as separation of nanoparticles, sensors, drug delivery, removal of heavy metals from aqueous solutions and chiral separation.

Abstract:

The identification of alternative and renewable sources of energy is one of the most important challenges that modern society faces, and has become more urgent and intense in the past few years. One of the most promising technologies is that of thermoelectric (TE) devices, which allow one to transform heat into electrical energy or vice-versa. Several technological problems still need to be solved before TEs become a competitive energy source. In particular, the efficiency of TE materials will have to be roughly doubled before large-scale applications can be envisaged. New perspectives on TEs have been opened recently by their structuring at the nanoscale. This has allowed experimentalists to obtain impressive efficiencies in thin film samples in the lab, but transfering these new ideas to a nanostructured bulk material suitable for mass production remains a challenge. Theoreticians have played a central role proposing new material and explaining how the intrinsic limits of bulk TE materials can be overcome or bypassed.
The present project aims to study and optimize the TE properties of promising SrTiO3 based oxides for high temperature TE applications by performing electronic and transport calculations. Engineering the electronic band structure of SrTiO3 alloys with Nb(V) and that of LaVO3(KNbO3) nanostructures embedded in a SrTiO3 matrix, the project aims to design new oxide materials with high TE efficiency and new ideas which can be used to achieve this high efficiency.
