Abstract:

Artificial intelligence tools (neural networks and genetic algorithms) will be used in order to find the most appropriate reaction conditions for obtaining and characterization of new polysulfone-silsesquioxanes membranes impregnated with ionic liquids (PS-POSS-IL) (with predetermined characteristics) as new materials suitable for CO2 capture and storage. Starting from a set number of experiments, in which new types of PS-POSS-IL will be prepared and characterized by changing the reaction conditions (including use of different polysulfones, different silsesquioxanes and a different content or different type of ionic liquid), a data base will be elaborated in order to use it further for modeling with artificial intelligence instruments (neural networks and genetic algorithms). In this way the best reaction conditions can be chosen for obtaining the best PS-POSS-IL membranes as superior materials for adsorbtion/ separation of the CO2. In the first stage of the project, the polysulfones will be obtained and characterized, then the needed silsesquioxanes. Thereupon the membranes will be elaborated from the previous obtained materials, using the phase inversion process. After the membranes will be prepared, they will be characterized for determining the most conducive conditions for manufacturing membranes with the highest CO2 adsorption performance, for their use in separation of CO2, using the artificial intelligence tools (especially neural networks).

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:

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.
