Abstract:

In this project, novel heterojunction thin film electrode-based photoelectrochemical (PEC) water-splitting devices integrated with photochargeable zinc ion batteries (photo-ZIB) will be developed to provide hydrogen (H2) in a clean, sustainable, efficient, and cost-effective manner. The bias potential required by the system to be produced is met by photo-ZIB, which can be directly charged by sunlight. Specifically, we propose creating heterojunctions of zinc oxide nanostructures with kesterite-type and chalcogenide-type semiconductor thin films for highly efficient photoelectrochemical (PEC) reactions. Additionally, compositionally complex ceramics will be utilized to enhance the photo-anodes' stability and catalytic activity. Dark cathodes based on high-entropy ceramics will be obtained to provide a cost-effective alternative to current technology. Thus, it aims to design an innovative device that can be an alternative to the classically used photovoltaic solar cell-electrolyzer systems in terms of cost and efficiency.

Abstract:

This project addresses an issue of major scientific interest, namely long-term solutions to energy crisis and environmental challenges. The overall objective of the project is to develop new composite materials based on carbon structures (CS) (AC and g-C3N4) and TiO2 nanotubes (TNs) with tunable properties by controlling their shape, defects, and interface processes for dual applications in photocatalysis and supercapacitors. The scientific objectives are: SO.1 Developing novel nanocomposites based on carbon structures CS and TNs with specific features for photocatalytic and supercapacitive applications; SO.2 Testing of the produced nanocomposites in photocatalytic applications for degradation of organic molecules (antibiotics or dyes) and supercapacitor applications.S.O.3 Increasing international visibility by applying for European projects, enhancing connections and research networks with the Republic of Moldova, promoting Moldovan researchers into international networks, connecting academic partners with industrial research, and training young researchers.The primary goal of the project is to develop and evaluate the electrochemical and photocatalytic performance of such composite materials in order to achieve enhanced photocatalytic response (20% higher) and high-performance SCs devices with high energy density (15 wh/kg), high power density (more than 100 kw/kg), and long cycle life (20% higher) that are competitive with those already on the market.

Abstract:

Supercapacitors (SCs) are known as promising energy storage devices. Electrodes are key components in producing SCs, and the strategies for selecting the right electrodes play a decisive role in their specific power and energy storage performance. The project aims to diversify the 3D carbon materials derived from MOF by impregnating them with metal oxides (MOx) such as ZnO, MnO2, and WO3 to be used as electrode materials in hybrid SC devices. Here, their electrical properties are enhanced by controlling and tailoring the size, shape, defects, interfacial phenomena, and porosity of the nanostructures of the materials. The high-sensitivity EPR spectroscopy method is used to characterize the defect structure, such as the carbon-related defects or the defects associated with oxygen vacancies of the proposed materials. The characterization by spectroscopic techniques on the surface and interface of the electrodes and their influence on the electronic, optical, and electrical properties of the nanocomposites is carried out to improve the properties of the material so that new SC electrodes in a solid-state configuration using a 3D-carbon structure/MOx are obtained to improve the energy storage capacity and achieve operating voltages higher than 3 V.

Abstract:

The project aims at offering an alternative to already available random access memories in the form of integrated Rashba-type platform for data storage and additional bit manipulation accompanied by the consequent validation of the mixed functionality as: i) spin-orbit based multiferroic random access memory (MfRAM) and ii) logical gate able to perform binary operations. By the end of the implementation time, the validation for the mixed, logical gate and spin-orbit torque MfRAMs based on the coupling between the spin and charge degrees of freedom in Rashba coupled semiconductor and multiferroic systems will be delivered. The Rashba-coupled metal/semiconductor systems will be the interfaces of ferromagnetic materials (Mn, Fe, Ni) with Ge(111), which were shown to exhbit large Rashba effects and large spin to charge conversion through inverse Edelstein effect while the Rashba-type multiferroics will be the interface of dissimilar materials: ferromagnets (Mn, Fe, Ni) and Rashba-type ferroelectrics (GeTe), with the relevant cross-coupling close to the contact region.

Abstract:

Water is the source of life and an essential resource for human survival. With fast socio-economic development and increasing population across the world, water environment crisis has drawn widespread concern for humanity nowadays. An improvement of water supply and sanitation, and a better management of water resources, especially in terms of water reuse, can greatly contribute to poverty reduction and can boost economic growth in low-income countries. Responding to these requirements the need of adopting new environmentally friendly technologies is necessary. Taking into account the state of the art in the field and the scientific results obtained in the last years by our research team, in this project we intend to develop photoactive ultrafiltration PVDF membranes modified with ZnO-MFe2O4 for water decontamination using advanced oxidation and separation processes. The achievement of the general objective involves the fulfillment of the following specific objectives: O1. Obtaining ZnO-MFe2O4 heterostructures with enhanced photocatalytic activity under visible light irradiation; and O2. Development of PVDF membranes modified with ZnO-MFe2O4 heterostructures for water decontamination using advanced oxidation and separation processes. For the realization of the project it is envisaged the use of appropriate infrastructure and a multidisciplinary young team. The results of the project will be disseminate by scientific publications-communications and project web-site.

Abstract:

In this project, we aim to develop an efficient and reliable method used to monitor intracellular proteins by Electron Paramagnetic Resonance (EPR) spectroscopy. For this purpose, we will create a cellular model expressing Green Fluorescence Protein (GFP) tagged with an array of metal-binding oligopeptides (MeBPep) designed to trap EPR-responsive metal ions, such as Mn(II) or Cu(II). This model will be used to develop EPR spectroscopy as a toolbox for comparative profiling.
