Abstract:

The scarcity of water resources is expanding worldwide due to the continuous growth of the imbalance between the availability and utilization of freshwater. This motivates researchers to find new water-saving methodologies and water management tools responding to future demands. The general objective of this project consists of the development of novel and low-cost material based on alginate and biochar functionalized with metal oxides and its application for the treatment of contaminated water, to support the implementation of strategies for mitigation of hydro-climatic extreme events, especially droughts in the catchment of different sources of irrigation water. Also, the material will be investigated for water saving and soil fertilization. The influence of this new material on bean crops will be studied, bean being widely used food due to their high protein content and vitamins. The specific objectives of the research are: Preparation and characterization of cost-effective new superabsorbent materials based on alginate and biochar functionalized with metal oxides. Assessment of the efficiency of recycling and reusing the superabsorbent material. Evaluation of the removal efficiency of organic pollutants from polluted water using the superabsorbent material. Testing the attenuation of antibiotic resistance genes and bacteria by the new adsorbent from greywater effluents using established molecular methods (qPCR and c sequencing); Assessment of the impact of the superabsorbent material on the physical, chemical, and biological properties of soil and its effects on growth-development, yield, and crop quality in agricultural plants under current and predicted climate change scenarios. The current project is pertinent to the work program topic, contributing to the management of water resources by adaptation and mitigation to hydroclimatic extreme events and management tools by preparation of new materials that will be used for water decontamination thus increasing the water reserve that can be used for irrigation. Also, these superabsorbent materials can be used to store and gradually release water during droughts. The project, by its objectives, fits the following topics of the call: Topic 1. Resilience, adaptation, and mitigation to hydroclimatic extreme events – by developing a mitigation strategy to cope with hydro-climatic extreme events, especially drought. Topic 2. Tools for water management - in the context of hydroclimatic extreme events – by developing tools (e.g. superabsorbent material, multi-risk approach) to support the design and implementation of strategies for mitigating droughts in a catchment to sea perspective. In addition, following the influence of the superabsorbent materials prepared in the project on bean cultivation under current and future climate change conditions of temperature and CO2 concentration in the atmosphere will provide knowledge on how the proposed solution will perform today and in the foreseeable future. (This is also addressed in Topic 2). Because the countries involved in the project (Romania, Italy, Moldova, Turkey, India) have different climates, it can also fit with Topic 3: Improved water governance in the context of hydroclimatic extreme events and international contexts - Addressing and encouraging international cooperation in the field of water, including management of transboundary water resources and contribution to Water Diplomacy. The novelty of the project: i) the material prepared; ii) 3 simultaneous applications of the same material: pollutants removal, swelling, and drought stress mitigation under current and predicted climate change scenarios for crop cultivation as model plant bean crop and soil improvement; iii) the application of the material prepared for solar desalination and the elimination of ARGs and ARBs.

Abstract:

The present project proposes the use of organic iminic ligands, with one or more C=N bonds, that exhibit intra- and intermolecular interaction abilities in the chemistry of hypervalent organotin(IV) compounds; a research project in a field of fundamental research, with potential for applications.

The proposed research activities will be focused on: (i) the design and characterization of new organotin(IV) monomers, polymers, heterocycles and chiral compounds containing iminic ligands; (ii) the synthesis and characterization of water-soluble, stable organometallic species (carbonates, nitrates, phosphates, etc.); (iii) the study of the influence of the nature of the organic groups attached to the metal on the oligomerisation degree; (iv) the study of the chemical reactivity of these new compounds (e.g. the possibility to obtain metal-metal bonds by extraction of the chalcogen, or their ability to coordinate to transition metals, their use in transmetallation reactions); (v) the use of new organic ligands containing one or more C=N bonds with controlled design which are able to provide protection for metal centres in homo- and heterometallic species with Sn-Sn or Sn-M bond (m = metalloid od main group metal, transition metal) through intramolecular N-Sn interactions, in addition to steric strains.
