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:

Document forgery is a criminal activity that causes billion dollar losses each year worldwide. Security paper is among the most important ingredients used in the fight against the forgery of private or public documents. The continuous diversification and sophistication of the paper securing techniques is one of the most important ways to erect fences against forgery attempts. The NanoMagSecurityPaper project aims to expand the diversity of high tech means for paper securing. The project’s strategic objective is to bring magnetic security paper on the security paper market. It is estimated that the Romanian security paper market alone will demand for tens of tons of magnetic security paper each year.

NanoMagSecurityPaper brings in the idea to obtain magnetic security paper by dispersing superparamagnetic nanoparticles in the wet cellulose pulp. The superparamagnetic paper thus obtained gets the functionality of security paper only together with appropriate validation methods and instruments. In order to meet this goal, joint applied research from the following three fields is necessary: 1. paper making, 2. magnetic nanoparticle/composite synthesis, and 3. magnetic sensing and validation. In order to meet the highest security standards, the authenticity checking procedures should make possible both a fast, handy and reliable first instance validation, and a sophisticated, albeit laborious, high security level validation. The NanoMagSecurityPaper will elaborate and test methods to produce high security level magnetic paper, by embedding in the paper composition magnetic nanoparticles and, for white color paper, magnetic composites. A handy and high sensitivity first instance validation method and instrument will be developed.

NanoMagSecurityPaper will achieve its objectives by transferring fundamental and applied knowledge on magnetometry, magnetogranulometry, magnetic sensing and magnetic nanoparticle/composite synthesis, from three Romanian academic institutions to three Romanian industrial partners: SC CEPROHART SA - security paper producer, SC ROSEAL SA - magnetic nanoparticle/composite producer, and SC DATRONIC-NCIP SRL – electronic equipment producer. NanoMagSecurityPaper will provide high-tech added value to the product portfolio of the consortium industrial partners, as well as a deeper scientific knowledge transfer expertise to the academic institutions of the consortium.

NanoMagSecurityPaper will also open means for the development of securitization techniques for a wide range of diamagnetic materials like paints, textiles, polymeric composites, and others.

Abstract:

DONTAS project presents the research, development and innovation of new tools, like surgical methods and techniques by using metal implants coated with smart composite layers based on advanced nanotechnology for medical applications. More specific, nanostructured phosphates (nanoPHOs), such as nano hydroxyapatite (nanoHAP) incorporating different additions of silicon as an osseopromotive agent, as well as magnesium and zinc requested for bone metabolism are synthesized and structural, morphological and biological characterized. Further smart composites, made of said nanoPHOs incorporated into natural polymers (collagen type I and/or chitosan) are developed to mimic the characteristics of natural bone. In addition, nanoPHOs are incorporated into synthetic polymers (PMMA or poly-Bis-GMA) for comparison with the above ones. Our preliminary results indicate a remarkably difference among morphologies of various DONTAS composites ranging from particulate matters to fibers mineralized with nanoPHOs. Also, metal implants are realized by a strong cooperation in DONTAS consortium, formed of two prestigious universities and two important national institutes, as well as a small and medium sized enterprise (SME). The metal implants are advanced processed to reach the surface characteristics to be well osteo integrated in bone. Furthermore, the surface of implants is functionalized by coating with DONTAS composite layers to efficiently promote the bond of the implant to the bone. This inventive project tackles the bioactivity of the above new composites assembled as scaffolds on implants (rods, intramedullary rods or plates), which will be thoroughly examined in cell cultures of osteoblasts. DONTAS surgical tools and smart composites will have large medical applications for repairing and replacement of bone in orthopedic surgery and in reconstructive medicine.

Abstract:

Metal–organic frameworks (MOFs), a new class of crystalline materials exhibiting extremely high porosity, attracted attention as hydrogen-storage materials, similar to the best activated carbons at 77K. However, for applications in transportation a high H2 sorption capacity at ambient temperatures with low adsorption/desorption enthalpy are required. The promising results for room temperature H2 adsorption on MOFs composites with Pt/activated carbon recently reported were assigned to ‘‘spillover” effect but the controversy raised due to contradictory literature results is still open and needs to be solved due to its possible high impact on hydrogen storage.

The goal of the project is to assess the enhanced hydrogen adsorption reported in literature and to find new materials and methods to improve the H2 storage in solid state materials. New approaches for building the intimate contact at the interface of MOF with metal/support catalyst will improve the knowledge of the routes and methods with positive effects on hydrogen adsorption by MOFs based composites. Systematic studies will be performed on MOF/catalyst composites, employing alternative and complementary methods, with emphasis on: controlled ball-milling procedure, influence of the catalytic metal (Pt, Pd, Ni) or support, direct synthesis of different MOFs on catalyst, validation of hydrogen uptake measurements, identification of the major factors implied in the hydrogen transfer at the MOF/catalyst interface.
