I started to work in the field of the water cleanup technology since my studies as B.Sc. and M.Sc. student. After M.Sc. studies, I continued the work in the field of water cleanup technology as PhD student with scholarship at "Gheorghe Asachi” Technical University of Iasi, Romania in the frame of POSDRU/107/1.5/S/79407 project (2010-2013). Before joining the National Institute of Research and Development for Technical Physics (NIRDTP) Iasi, Romania, I worked as a Chemical Engineer at "Purolite S.R.L." , at present "Purolite, An Ecolab Company" (2014-2018). This period had an important role in my training as Chemical Engineer fact that also shaped my skills as engineer in new area of chemistry applications . Starting 2018 I joined by competition as Research Assistant the NIRDTP and continued the work in the same field of water cleanup technology as research direction, currently having the position of Scientific Researcher.

Abstract:

Air pollution is currently the most important environmental risk to human health, and it is perceived as the second biggest environmental concern at national and international level. In this context, the replacement of the energy from fossil fuels with clean/green energy sources is imperative and the use of Direct Methanol Fuel Cell represents a viable solution to pollution issues, being one of the best candidates for the next-generation power source. The scope of the project proposal is to overcome two of the technical issues concerning the DMFC performance by: (i) developing a new preparation method of CoPt nanoparticles in order to increase the catalysts activity and decrease the platinum content and (ii) increasing the catalyst stability by exploiting the unique properties of CNTs. Within the framework of this project, a complex experimental study on the preparation, characterization (dimensional, morphological, structural and magnetic) and testing of new CoPt/CNTs nanocomposite materials will be accomplished, in order to choose the adequate catalysts in terms of nanoparticles diameter, morphology, structure and composition. By fulfilling the project proposal activities, we will contribute to the improvement of DMFC performances and stability and we will develop the experimental research work in the field of preparation of new catalysts based on CoPt /CNTs nanocomposite, focused on practical and immediate applications to renewable energy sources and catalyst industry.

Abstract:

The main aim of the NANOARHITECT is to consolidate a research team and an independent research program focused on the design and development of multifunctional core@void@shell nanoarchitectures towards visible light dual-functional photocatalysis. Besides the general objective, NANOARHITECT will smoothly run along the route defined in this two-fold strategy of sustainable hydrogen production accompanied by the oxidative degradation of pharmaceutical drugs pollutants in a single process, achieving all defined targets and eventually going further based on the following specific objectives: (SO1) development of fundamental materials based on the synergistic combination of different types of hierarchical-like Al;Rh;La:SrTiO3/Cc (Cc: FeOOH, NiOOH and FexNi1-xOOH) composite core entrapped in SiO2 matrix to generate innovative core@void@shell nanoarchitectures with enhanced visible light adsorption, highly effective active sites exposed and optimized mass transport to (SO2) acquire of fundamental knowledge around dual-functional photocatalysis by boosting the photocatalytic activity in all dimensions. Filling two-goals-with-one-action, NANOARHITECT will lay the foundations on a unique opportunity to firstly develop these innovative techniques from the ground up in an ambitious project such as this to inspire new approaches on old problems in photocatalysis with expected research outputs that will make a positive contribution to the European excellence research area.

Mischmetal-Fe-B nanoflakes for a new class of anisotropic permanent magnets Call name: P 1 - SP 1.1 - Proiecte de cercetare pentru stimularea tinerelor echipe independente - TE-2021

Abstract:

Permanent magnets are critical components for modern life, being used from home applications to robotics, green energy, and military applications. The most powerful and widely used magnets available today are NdFeB magnets with additions of Dy, Pr, Tb. Elements like Nd, Dy, and Pr being certificated as critical materials due to the higher price and less abundance.

In this context, the current project proposes the replacement of critical rare earth such as Nd, Dy, Pr in the RE-Fe-B system with mischmetal (MM) to develop a new type of nanocomposite magnets based on anisotropic nanoflakes (MM2Fe14B). The motivation for this choice comes from the fact that MM is a natural mixture of Nd, Pr, La, and Ce and does not require separation. Therefore, the elimination of polluting processes of separation and purification of rare earth leads to a significant reduction of costs and waste. However, the total replacement of Nd and Dy with MM leads to a decrease in Curie temperature, saturation magnetization, and thus the energy product (BH)max. The project also comes up with solutions to remove these shortcomings by nitriding nanoflakes (interstitial penetration of nitrogen atoms into the cell structure of the MM2Fe14B phase) and by switching between the magnetic phases of the nanocomposite magnet MM2Fe14B/αFe. Thus we can say that the resulting magnets will develop magnetic performance capable of filling the gap between NdFeB and hard ferrites.

Abstract:

Last decades brought a considerable development of technologies based on ordered systems. Starting with semiconductor physics and photovoltaics, technologies soon evolved towards the utilisation on large scale of thin films and of surface / interface properties. Example go nowadays from data storage and readout (electrostatic or magnetic memories, giant magnetoresistance) to catalysis, gas sensors or photocatalysis (surface phenomena), and towards interfaces with biological matter (biosensors, templates for tissue reconstruction, interfaces between biological electrical signals and microelectronics). In Romania, crystal growth is performed since half a century; nevertheless, during the last years these activities fade out and need to be seriously reinforced, especially with the advent of new laser and detector technologies required by the Extreme Light Infrastructure facilities. Also, surface science started to be developped seriously only during the last decade, together with techniques involving self-organized nanoparticles, nanoparticle production etc. The main goal of this Project is to gather the relevant experience from the five partners, namely the experience in crystal growth from the University of Timișoara, with the surface science, nanoparticle and nanowire technologies developped by NI of Materials Physics, the cryogenic and ultrahigh vacuum techniques provided by the NI for Cryogenic and Isotopic Technologie, and the experience in ordered 2D systems (graphene and the like) owned by the NI for Microtechnologies (IMT). This common agenda will result in a coherent fostering of technologies relying on ordered systems of variable dimensionalities: 0D i.e. clusters or nanoparticles, including quantum dots; 1D i.e. free and supported nanowires and nanofibers; 2D: surfaces, interfaces and graphene-like systems; and 3D crystals of actual technological interest, together with setting up new ultrahigh vacuum, surface science and electron spectroscopy techniques.
