Abstract:

The growing need for energy requires development of new energy sources/carriers and more efficient utilization of energy. Hydrogen is the ideal energy carrier due to its natural abundance and non-polluting nature.
The development of hydrogen storage technologies for mobile applications still requires overcoming some technical barriers.
Different hydrogen storage paths have been envisaged: from the classical storage technologies, namely pressurization and cryogenic liquefaction, to the solid phase storage in metal hydrides, or physisorbed on a solid surface (metal-organic frameworks, covalent organic frameworks) and the organic liquid hydrogen carrier (LC) under ambient conditions.
Chemical hydrogen storage can became competitive if the storage material fulfils some requierements: high gravimetric and volumetric hydrogen content under ambient conditions, energy-efficient reversible charge and discharge, the absence of byproducts, long-term stability, low toxicity, easily available at a large scale and at a low price. The challenge is to find suitable organic carriers.
Formic acid is a promising candidate for reversible hydrogen storage. The aim of this project is to study formic acid decomposition/formation using a new type of catalysts: metallic nanoparticles confined in metal-organic frameworks, to exploit the nanoparticles confinement and the nanoscale properties for reactions of formic acid dehydrogenation and carbon dioxide reduction under mild conditions.

Abstract:

In modern dentistry, both the early prevention of tooth decay and the development of new and efficient restorative materials are generally targeted. Although tremendous efforts have been made in promoting oral hygiene and fluoridation, the prevention of early caries lesions are still challenges for dental research and public health. Recent studies have indicated that nanotechnology might provide novel strategies in dentistry.
Graphene consists in a one-atom-thick planar sheet of sp2–bonded carbon atoms arranged in a hexagonal lattice. Graphene is considered to be the “thinnest and strongest material in the universe” and therefore it has remarkable physical and chemical properties, including superior Young’s modulus (1 TPa) and tensile strength (130 GPa). Recent studies have shown that graphene can be used as nanofiller and can dramatically improve the properties of polymer-based composites at a very low loading (0.1-5 wt.%).The results so far reported in the literature indicated that graphene/polymer composites are promising multifunctional materials with significantly improved tensile strength and elastic modulus, electrical and thermal conductivity. Despite some challenges and the fact that carbon nanotubes/polymer composites are sometimes better in some particular performance, graphene/polymer composites may have wide applications in dentistry due to their outstanding properties and the availability of graphene in a large quantity and at low cost.
Within the BIOGRAF project we plan to develop: ► a new nanocomposite material based on biocompatible polymers and graphene to be used in dental restorations ► new ex vivo tests to identify the host reaction to this material, in relationship with some biologic risk indicators. The final aim of the project is to develop modern and standardized therapies of caries lesions through the development of the novel nanocomposite material based on biocompatible polymers and graphene.
The present research project fits very well into the research domain 7. Materials, processes and innovative products since a new nanocomposite material with graphene will be manufactured which will fulfill the bio-safety criteria and have biocompatible properties with the local cellular environment. By its specific objectives BIOGRAF corresponds to the research thematic 7.1.6. Advanced materials and biomaterials for improving the quality of life (health, sport, education) because: ► a new nanocomposite material with graphene will be developed, for better medical treatments ► complex inter-/multidisciplinary studies will be performed, in order to elaborate and validate new standardized therapies based on advanced materials ►the development of a new perspective in dentistry, based on advanced theoretical and practical knowledge ► a research network will be developed which can ensure human resources for the top scientific research ► articles will be published in highly-ranked journals (ISI) ► research papers will be presented at international conferences ►valuable information will be disseminated among PhD/PostDoc students and researchers in the field of nanocomposite materials ►the equipments that will be purchased will develop the existing R&D infrastructure.
BIOGRAF project is aiming to deliver the following end-product(s)/ expected results:
► a new nanocomposite material with graphene, to be used in dental restoration therapy
► one laboratory technology for the synthesis of the nanocomposite material
►3 ISI papers, in highly ranked journals
►a patent.

Abstract:

The main concept of the project proposal is the study of the influence of the application of some new therapies involving the use of new biomaterials based on metallic nanoparticles and natural organic compounds separated from fruits (anthocyanins, aminoacids, poliphenols) at skin level. The macroscopic and microscopic changes induced by metallic nanoparticles (nanomaterials) applied topically on skin can be evaluated by using high frequency ultrasound. By means of the obtained results, a mathematical model of how the nanoparticles help organic molecules to penetrate the skin and to influence the evolution of collagen layer will be developed.

Abstract:

This project proposes the identification of parameters necessary to obtain in a single step synthesis high-purity graphenes, decorated with Au or Pt nanoparticles. To accomplish this task, we propose the development and study of novel Au or Pt supported on MgO catalytic systems, that can be used in the inductive heating-CCVD method, to grow composites of graphenes and Au/Pt nanoparticles. We propose to study the influence of the synthesis conditions on the morphology of the graphene layers and the uniformity of Au/Pt nanoparticles distribution throughout the graphitic structure. The integration of the noble metal nanoparticles (Au, Pt) into the graphitic structure of layers, rather than just attaching them chemically on the graphitic surface, has some major advantages related to the electronic properties, better structural integrity, and better distribution uniformity. Finally, the graphenes decorated with Au or Pt nanoparticles will be used as active components into highly sensitive electrochemical electrodes to study the oxidation processes of adenine, guanine and DNA strands. These studies could be the foundation for the development of new technologies with high sensitivity and specificity towards the understanding of various bio-chemical reactions that could include the DNA degradation. Moreover, the results of this study could be integrated in technological platforms used for the detection of various deseases and medical conditions.
