Abstract:

After the discovery of graphene with the set of properties that essentially distinguish it from other allotropes of carbon, ultra-thin layered materials, classified as 2D nanomaterials, enjoy a growing interest due to their unique properties. In this context, very recently become of interest 2D MOFs. But in the crystallization process, 2D layers stack on the basis of intermolecular interactions, leading to higher dimensional materials. To manifest behavioral particularities specific to a 2D material, they must be isolated individually or in multilayers with thickness/surface aspect ratio as small, which is a challenge that seek solutions through different approaches (top-down or bottom-up). The project idea is to design and synthesize two-dimensional metal-organic networks with extremely weak intermolecular interactions, which facilitate delamination in nanosheets. The originality and the key to success in this approach is the use of ligands containing permethylated silicon units which by their natural exposure shield the structure and prevent the establishment of noticeable interactions. New ligands and combinations thereof will be prepared and used to coordinate various metal ions or clusters. Nanosheets formed will be evaluated as such, but also the effect of their incorporation in silicone matrices for the development of materials responsive to stimuli. Their common nature creates the premises for a better compatibility and forming advanced composites.

Abstract:

A large percentage of commercial energy use is directed for heating and cooling in a variety of technologies where an effective management of heat transfer can lead to significant reductions of the amount of energy used and therefore the energy costs involved. Among these technologies, one of the most significant in terms of energy consumption is building operation, which by itself accounts for ~ 40 % of global energy consumption, and their heating and cooling alone requiring ~ 36 % of this amount. This represents an exciting opportunity to dramatically diminish energy use worldwide with the development of novel personal thermoregulatory clothing. The development of an “ideal” personal thermoregulatory clothing which harmoniously brings together the advantages of passive strategies (i.e. low cost, straightforward implementation, and energy efficiency) with the on-demand control capabilities of active strategies has remained elusive to date. This project proposes an integrated nanocomposite material garment with tunable thermal infrared properties to solve this scientific challenge, using inspiration from the static infrared-reflecting design of the space blanket and from the dynamic color-changing ability of squid skin. This material will be able to regulate a heat flux of > 40 W/m2 with a transient mechanical power input for actuation of 3 %.

Abstract:

Mimicking the living matter mechanism of cooperation by complementarity represents one of the most challenging tasks of supramolecular chemistry. For now the solution consists in using particularly designed molecular unimers, endowed with the necessary amount of chemical information.

The 5D-nanoP project is dedicated to interfacing the fundamental research area of constitutional dynamic chemistry with the practical approaches of medicinal chemistry and biomedical applications. In the spirit of a metaphor of Jean-Marie Lehn (Nobel Prize in Chemistry, 1987), the project aims to materialize the concept of 5D chemistry in designing, synthesizing, characterizing, and using molecules with conditional affinity, to build versatile supramolecular nanoplatforms able to vectorize compounds of pharmaceutical or biochemical relevance, and genetic actuators, all of them involved in physiologic and pathologic processes at cell- and tissue-level.

The project will add the layer of 5D chemistry over the backgrounds of molecular assembling line techniques to produce particulate nanoplatforms, self-assemblable in the virtue of the chemical information stored by the designed unimer molecules. Two modern techniques of building dynamic chemical structures will be considered: (i) the use of self-immolative linkers, and (ii) the space stepwise and time phased (microfluidic) assisted synthesis. To prove the applicability of the produced nanoplatforms, an ex vivo cell cultivation system will be developed to emulate tissue/tumor niches.

Eight teams will be involved in the 5D-nanoP project to cover the main addressed research areas: (i) the in silico molecular design, (ii) the development of a unimers chemical library, (iii) the development of a molecular assembling line, (iv) the conjugation of the developed platforms with chemical species of biomedical interest, (v) the build of ex vivo emulating niches, and (vi) the bio-oriented assessment of nanoconstructs efficacy.

Abstract:

It is proposed to develop an innovative and original 3D printing technology for electromechanical transducers (sensors and actuators) based on silicone dielectric elastomers (DETs) that will eliminate the disadvantages of their traditional processes, generally laborious, time-consuming and limiting regarding geometry complexity, dimensional accuracy, reproducibility. Also, taking into account the current challenges focused on material issues in additive manufacturing, where the use of silicones is just beginning, the proposed technology first involves the formulation and optimization of the dielectric and conductor layers for 3D printing of DETs, the construction of the printer and the development of adaptable software for production of the units with different shapes and complexity degrees.

The proposed solvent-free material is based on customized polysiloxanes in terms of molecular mass and structure, and consists of a mixture of two polysiloxanes side-functionalized, one with vinyl groups and the other with thiol groups. In case of electrode material, carbon black is added. Both mixtures contain organic photoinitiator capable of triggering upon UV irradiation the crosslinking of polysiloxanes by a "click" reaction (thiol-ene addition) with silicone elastomer formation. Taking place at room temperature, in the absence of metal-based catalysts and solvents, the process is a "green" one and the material is known to be biocompatible and environmentally friendly during use and reintegration into the natural cycle. The sensors and actuators will be printed using a dual-head cartesian system with one nozzle for injecting the conductive polymer and another for the dielectric one. Immediate applications are aimed at civil engineering as sensors for monitoring the strain in the structural elements, as dampers for attenuating the seismic movement in buildings, bridges and foundations but also in the field of material testing (determining the Poisson ratio in soil samples).

Abstract:

Autocatalysts are used to convert vehicle exhaust (carbon monoxide, nitrogen oxides, hydrocarbons, etc.) into less harmful products, such as: carbon dioxide and nitrogen. Platinum group metals (PGMs) are the active component in autocatalysts and consequently the auto industry is the largest PGM consumer. Limited PGM resources demands recycling to support an expanding auto market. Traditional recycling methods are using high temperatures and highly oxidative agents (e.g. aqua regia) making them large energy consumers and environmental pollutants. As a result, there is a need to develop alternative ways to recycle PGMs with a significant decrease in energy consumption and a reduced impact on the environment. ECOTECH-GMP project at hand draws from the knowledge, skills and competences of top leading Romanian research institutions in materials science, physics, chemistry and engineering for creating the know-how to develop the eco-technologies required to recycle PGM with zero emissions. There is currently no such technology available in the world. Four sub-projects are proposed to solve the issue of PGM eco-recycling, encompassing electrochemistry, coordination chemistry, hydrodynamics and bioelectrochemistry. The sub-projects are intertwined and function in synergy to deliver several solutions to the issue at hand. The potential of this project is mesmerizing for any interested company: small initial capital, low energy consumption and high throughput. The benefits for the society at large are thrilling: improved public health because of decreased toxic pollutants (chlorides, nitrates, nitrides, etc.) and creating new jobs owing to the potential of this technology to transform into an industry.

Metal-organic frameworks with hydrophobicity fine-tunned by using silicones chemistry Call name: P 4 - Proiecte de Cercetare Exploratorie

Project website: http://www.silmofs.icmpp.ro

Abstract:

The project is devoted to design, synthesis and structural characterization of metal-organic frameworks (MOFs) with controlled hydrophobicity required for certain applications such as gas storage, drug delivery systems, self-compatibilizing fillers for special energy composites, supercapacitors, etc. Different from the approaches reported in literature consisting in attaching hydrophobic groups near coordination sites, or post-synthetic grafting of such groups onto linkers, here will be used mainly ligands with siloxane spacers having attached to the silicon atoms one of the highest hydrophobic group, methyl, but also some derivatives inserting more longer (octyl), more rigid (phenyl, diphenyl), more polar (chloropropyl) or more hydrophobe (trifluoropropyl) groups in order to fine tune moisture stability of the resulted MOFs but also their lipophilicity and crystallinity. The high flexibility of the siloxane backbone allows the organic groups to be arranged and presented to their best effect. In addition, metals in high oxidation state will be used. The key steps in achieving the project objectives consist in engineering the spacer by using new approaches in silicones chemistry (i.e., Piers-Rubinsztajn reaction), attaching coordination groups (by thiol-ene addition or nucleophilic substitution), construction of MOF's and their isolation in a form accessible to characterize accurately. Thus original polydentate ligands mainly consisting in polycarboxylic acids and N-donor heterocycles with controlled diorganosiloxane or silane spacers will be obtained and used to built MOFs. The rare examples of assembling using the flexible linker, apart from those published by the authors of this proposal, and limited investigation in the field opens the innovative perspective for new knowledge and unique properties of MOFs.

Abstract:

The project responds by excellent science (future and emergent technologies) to one of the grand challenges facing EU society, i.e., secure, clean and efficient energy. Dielectric elastomers (DE) have emerged as promising smart energy-transduction materials ofering many advantages over other technologies, having good performance as generator (high strain, energy density, efficiency) and better material properties (low cost, high compliance, durability and environmental tolerance). Four major classes of dielectric elastomers have been established so far in this area: natural rubber, acrylics, polyurethanes and silicones, the latter occupying a special place by their unique properties and versatile chemistry. In this project, starting from the experimental proof-of-concept (TRL3) on the feasibility of energy harvesting devices built from silicone elastomers, the technology will be developed to TRL4. Thus, the project will deliver a laboratory-scale technology able to produce DEs energy harvesting elements adjustable on request, built up from alternating, highly stretchable and compliant dielectric/electrode layers, based on different silicone formulations. An original approach to ensure the best compliance between the dielectric and the electrode will consist in their co-crosslinking. The material characteristics will be optimized by synthesis and mixing with specially designed fillers, while the element geometry and number of layers will be adjusted according to end-user requirements. In doing so, special attention will be given to the choice of materials, working methods and their optimization, keeping in mind the principles of green chemistry. Thus, the synthesis of polymers and fillers, the film forming processes and co-crosslinking methods will be approached as to proceed as clean and cheap as possible, minimizing the use of solvents, avoiding by-products by using addition reactions with emphasis on click chemistry, and using unconventional energy sources.

Project website: http://www.polywec.org/

Abstract:

Wave energy has a great potential as renewable source of electricity. Studies have demonstrated that significant percentage of world electricity could be produced by Wave Energy Converters (WECs). However electricity generation from waves still lacks of spreading because the combination of harsh environment and form of energy makes the technical development of cost effective WECs particularly difficult.

PolyWEC introduces a new class of Polymeric WECs (PolyWECs), characterised by the employment of Dielectric Elastomer (DE) transducers.

The goal is to introduce a radical change in the traditional architecture of WECs that usually includes three basic components: mechanical wave absorbers, a mechanical transmission and a power take-off system. Due to their nature, PolyWECs can be conceived in a way that such three components are integrated into a single deformable lightweight and low-cost polymeric element. DEs have been largely investigated in the form of actuators for robotics and ICT applications. Preliminary studies on energy generation through DEs demonstrated their great potential in terms of cost effectiveness, efficiency and reduced complexity. Due to their intrinsic low mass, flexibility and resilience, as well as their capacitive nature and high voltage operation, DE technology perfectly matches the requirements of WECs.

Abstract:

The project aim is to bring developments in the metal-containing materials field by the preparation of new metal-organic networks using ligands with high flexible siloxane spacer between the complexing groups. Networks having single metal ions or polynuclear clusters as nodes will be prepared. The later will be obtained and subsequently used as secondary building units (SBUs) or generated in situ concomitantly with the network formation. Original di- tetra- and polycarboxylic acids as well as amine ligands containing siloxane moieties will be used as SBUs for the metal-organic structures infinitely extended into one, two or three dimensions (1D, 2D or 3D, respectively) via more or less covalent metal-ligand bonding. The siloxane moieties confer flexibility to the networks, thus structural adjustment through rotations and twists of structural units are expected, leading to better uptake of different guest molecules. Both building blocks (siloxane ligands and metal clusters) and networks prepared on their basis will be fully characterized from structural point of view by using adequate techniques (elemental, spectroscopic, X-ray diffraction). The specific properties (as for example: sorbtion behavior, magnetic, catalytic, biological, etc.) will be evaluated in order to identify possible applications of the new materials.

Abstract:

The project aims to study, to develop and to preliminary test biomimetic structural and functional entities, able to act as gene transfection vehicles of non-viral type, and having a DNA packaging capacity of about 2  5 kilobases. The main features of these entities are: (i) the general structure of a polyplex, (ii) the functionality of a cargo-complex that chemomimic the histones, morphomimic the nucleosome and biomimic a virus like gene vector, (iii) the ability to include or to reversibly bind and transport (bio)chemical species necessary to assist the DNA vehiculation and trafficking, (iv) are based on fullerene-rich polymers and / or dendrimers, (v) the capacity to associate to artificial extracellular matrices, in order to generate gene delivery systems with transfection ability, for ex vivo applications. The developed entities will represent effective tools in genetic and tissue engineering, useful in health restoration, life quality enhancement, and to cure tissue and human organism deficiencies. The envisioned engineering strategy to build biomimetic entities may sustain a spin-off type transfer of knowledge towards hi-tech application areas, with a clear echo in clinics and, finally, in human health. The project involves seven complementary teams hosted by four research and academic institutions. In equilibrated ratios, senior, young and junior researchers will collaborate inside the project frame.

Abstract:

Starting from the incompatibility of polysiloxanes with most of the organic polymers, the project aims to increase the knowledge on tailoring the biphasic morphology in siloxane-containing systems, in order to obtain nanostructured materials with special properties and potential top-field applications. We will try to bring new insights into the structure-morphology – properties relationships of siloxane-containing multifunctional materials. New organo-siloxane systems (copolymers, polymer blends, polymer-dispersed systems) will be obtained and studied to observe nano-organization in solid state, in melt or in solution and to understand the influence of the biphasic morphology over bulk and surface properties. The synthesis of siloxane-containing copolymers with various architectures will be realized by polycondensation or polyaddition reactions, starting from preformed macromers. The structures will be confirmed by spectral methods (NMR, FT-IR) and their properties will be investigated by DSC, DMA, UV-VIS spectroscopy, polarized light POM. The biphasic morphology and nanostructuration will be evidenced by TEM, SEM, AFM, XRD and XPS. The potential of siloxane based surfactants or liquid crystals as nanoreactors or nanoconteiners will be investigated. We will test the preparation of nanoobjects, including polymeric nanoparticles, by nanoprecipitation or polymerization/polycondensation reactions in nanoreactors consisting of biphasic organo-siloxane supramolecular assemblies. The results will be evaluated for subsequent use as disperse phase in polymer blends and as delivery vehicles. Mostly biocompatible/biodegradable materials will be designed and waterbased formulations for medical and personal care use will be explored.
