Abstract:

(Poly)saccharides represent ideal natural sources for the eco-friendly hydrothermal synthesis of semi-carbonized materials (hydrothermal carbons, HCs). HCs are nowadays considered alternative green conductive materials to more expensive graphene or carbon nanotubes (CNTs). The main objective of the proposal is the development of a new generation of sustainable electrochemical sensors constructed from Cu-based/(poly)saccharide-derived HCs composites. The engineering of HCs supports through hard/soft template strategies or the obtaining of HCs/CNTs hybrid structures gave rise to stable mesoporous materials with controlled pore structures that are expected to enhance the conductivity of the carbonaceous materials. The embedding of Cu-based nanoparticles into the HCs matrix or supported on the pre-designed porous HCs materials will lead to composites of which sensitivity toward several analytes will be tested. The social and environmental impact, relying on our scientific results, represent a step forward to a cleaner environment. The involvement of young researchers in our team will help them to acquire knowledge and new research skills and will also familiarize them with research themes related to green chemistry issues, like the minimization of waste and clean synthesis.

Abstract:

Polynuclear complexes are very appealing due to their physico-chemical properties which can be exploited to envisage new molecular-scale magneto-optical devices, as for example high-density storage devices, display devices, photo-switchers or quantum computers. Cyanido metalloligands are very popular for constructing heterospin complexes due to the ability of the cyanido bridges to efficiently mediate magnetic interactions between paramagnetic metal ions. Heteroleptic cyanidometallates allow a higher control over the dimensionality of the resulting heterometallic compounds in comparison with their homoleptic analogues due to the chelating ligands which account for the decrease in the number of the cyanido ligands and to the smaller negative charge. The rare-earth ions are an advantageous option in the assembly of cyanide based polynuclear complexes due to their magnetic features, strong spin-orbit coupling and high magnetic moments, that are prerequisites to attain slow relaxation of the magnetization (molecular nanomagnets) and long-range magnetic ordering (molecular magnets). Moreover, the 4f ions exhibit interesting luminescent properties, NIR and visible emission. The main objective of the project is the design and synthesis of new magneto-luminescent molecular materials based on d-f heterometallic systems. A large variety of structures are envisaged to be assembled from heteroleptic cyanido complexes of 3(4,5)d metal ions and hydrated Ln(III) ions/or complexes of 4f metal ions with polydentate ligands. Considerable attention will be devoted to molecular materials with functional properties, both magnetic and light emissive properties. The design of a new generation of molecular materials with tailored magnetic and optical properties would highly contribute to the advancement of the multifunctional systems suitable for constructing magneto-optical devices. An important goal of this project is the dissemination of the results in highly ranked ISI Journals.

Abstract:

The goal of the present project represents the development of new inorganic biocidal agents toward prokaryotic and eukaryotic microbial strains, in planktonic and biofilm adherent state. Its general objective is the optimizing of the design for zinc oxide based nanomaterials, using eco-friendly synthesis in order to reach an effective antimicrobial activity, and the component/subsystem validation in laboratory environment. The obtained ZnO crystallites lies in the nano range. In these context the specific objectives of the project are:

1. selection of the synthesis procedure in terms of antimicrobial and cytotoxic activity;

2. for the selected synthesis procedure, the optimization of the experimental parameters in terms of antimicrobial and cytotoxic impact;

3. validation in laboratory environment of the antimicrobial and cytotoxyc activities;

4. validation in laboratory environment of the synthetic procedure;

5. dissemination and intelectual property protection.

This project aims to develop an inorganic antimicrobial material from technology maturity TRL 3 to TRL 4. The technology maturity TRL 3 of the already undertaken research is shown by: (i) the concept of ZnO nanomaterials with antimicrobial properties obtained via eco-friendly methods is proved experimentally and its efficiency is verified, (ii) each component of the assembly, namely ZnO as inorganic material, the eco-friendly synthesis of ZnO, and the antimicrobial activity of the resulting materials were tested. The final parameter of interest is the antimicrobial activity of these ZnO materials. According to the proposed objectives, the implementation of the project will lead to the integration of the three components in order to establish the functionality of the assembly, the antimicrobial tests being carried out in suitable conditions in accordance with widely approved methods.

Abstract:

The heterometallic complexes of various dimensionalities and topologies are very appealing for molecular magnetism. The main objective of the proposed project is the design and synthesis of new low dimensional magnetic heteropolymetallic molecular materials (from 0-D to 2-D). Using a bottom-up, rational approach, by assembling heteroleptic cyanido metalloligands with mono or bimetallic molecular bricks, heterometallic coordination polymers are synthesized. Molecular nanomagnets (Single-molecule magnets, SMMs and Single-chain magnets, SCMs) and ferrimagnetic chains with SCM behaviour are particularly envisaged. Moreover, the ferrimagnetic chains, ferromagnetically interacting through hydrogen bonds, can exhibit 3-D (supra)molecular magnet properties. A special attention will be devoted to multifunctional molecular materials, by combining magnetic properties with optical properties, chirality or luminescence. The project has an interdisciplinary character and will be a collaborative effort involving PhD students, postdoctoral and experienced researchers.

Abstract:

The present project has as general scientific objective the developing of innovative green strategies polysaccharides-assisted for the design/synthesis of tailor made oxide-based nanomaterials, exploiting polysaccharides diverse and versatile properties (water-solubility, polyfunctionality, hydrophilicity, chemical reactivity, chirality, chelation/coordination, gelling, assembling and adsorption abilities). Precipitation, combustion, hydrothermal, forced hydrolysis and gel-templates methodologies will be elaborated in order to tune the size, morphology, structure and functionalization of the oxides materials. In these protocols, polysaccharides will be conditioned to act as: (i) stabilizers, (ii) templates (hard and soft), (iii) surface functionalizing agents and, (iv) carbon source. The developed synthetic approaches will use polysaccharides build up from D-glucose units linked by α- (starch, dextran) and β-glycosidic bonds (methyl-cellulose), with distinct polymerization degree, chain branching and rheological properties. ZnO, as well as ZnO/C and ZnO-polysaccharides composites of nanomeric sizes (50-300 Å) and various morphologies (including hierarchical and spherical structures as sphere, core/shell, hollow sphere, jingle-bell) and functionalizations are intended to be obtained. The assessment of a relationship with large degree of generalization between polysaccharide-synthesis-oxide represents benefits either from fundamental and applicative research points of view.

Abstract:

The main goal of the present proposal is to open a new interdisciplinary research direction and to build a team of experts in both fundamental and applicative research.

We aim to develop rational synthetic strategies leading to novel metallosupramolecular architectures with pre-established structures by linking homonuclear alkoxo-bridged Zn(II) nodes into lattices with polycarboxylate and/or divergent N-donor ligands. These will be further used for the preparation of nanosized ZnO materials. The physico-chemical properties of both precursors and ZnO particles will be investigated.

The interdisciplinary interaction of scientists with expertise in diverse areas (metallosupramolecular chemistry, synthesis of materials, materials characterization, and physics) will provide a better insight into the properties of the obtained systems.

Abstract:

The present proposal focuses on designing of a new generation of (supra)molecular heterotrimetallic magnetic materials. The main objectives of the project are:(i)obtaining of new heterotrimetallic molecular-based materials with modulated magneto-optical properties; (ii)achieving new physical properties which are intermediate between molecules and nanomaterials: these materials mark a crucial transition between molecular and nano-level;(iii) obtaining revolutionary multifunctional heterotrimetallic materials;(iv)developing of new theoretical models for understanding the magnetic properties of the obtained heterotrimetallic systems.The general method for the synthesis of complexes carrying three different metal ions is the self-assembly process between of pre-formed 3d-3d' and 3d-4f heterobimetallic units and suitable diamagnetic or paramagnetic metalloligands. The obtained compounds will be characterized by means of X-ray diffraction techniques on single-crystal and powder,magnetic measurements,various spectroscopic techniques according to their properties(FTIR, NIR-UV-Vis, fluorescence and circular dichroism) and elemental analysis.The project could be almost completely carried out in Romania due to the existent infrastructure.
