Periodic Reporting for period 2 - ENGIMA (Engineering of Nanostructures with Giant Magneto-Piezoelectric and Multicaloric Functionalities)
Berichtszeitraum: 2019-12-01 bis 2023-04-30
- The promising multi-layered nanocomposites consisting of the piezoelectric (BTO) and magnetic (Ni-NiO) layers were fabricated and studied using contactless interference profilograph.
- The ferroelectric BTO-based nanorods, plates, cubes, balls, and different whiskers and multiferroic CoFe2O4 nanorods were obtained by the hydrothermal method and characterized.
- The giant electrocaloric response in liquid crystals was revealed.
- Epitaxial multiferroic BiFe0.95Mn0.05O3 film was grown by pulsed laser deposition and the photovoltaic effect, switching by applying positive voltage pulses higher than the coercive field was discovered.
. The static negative capacitance, important for the design of the low-dissipation computing circuits was discovered as a result of modeling the domain structure in ferroelectric nanoparticles.
- 5 International conferences, 3 training workshops, and coordination meetings were organized.
- 65 scientific peer-reviewed publications were published in international peer-reviewed journals. The majority (73%) of the publications present the joint results of several Partners and are done in co-authorship; Three articles are published in the highest-rank journals of the Nature group. Approximately five publications are now “in print”. All these publications have open-access facilities, green or gold.
- 6 Joint Ph.D. thesis are accomplished.
- 10 outdoor outreach presentations in schools, universities, and at public events, communicating information about nanotechnologies and innovative engineering solutions were held. The information was also communicated through the project website (www.engima.ferroix.net) the Success Story of ENGIMA at the EU Horizon Research & Innovation Portal, and in the popular scientific Internet edition “Science Daily”, reposted by more than hundreds news-makers.
- The research activity of ENGIMA was presented at 85 research conferences, workshops, meetings, and trainings, involving a broad multisectoral audience. About eleven thousand persons viewed the project information.
From this point of view, ENGIMA may improve the long-term quality of daily life and health of the EU citizens, e.g. by contributing to the development of different smart systems. It is thus envisaged that the proposed project will contribute to filling the gap between Europe and other countries, in which the research activity on multifunctional films is much more advanced. In particular, the fundamental study of the FE, FM, multiferroic and multicolored systems in composite nanomaterial form will significantly promote the development of a European know-how on these materials. Since the area of the project has just emerged, a part of the project (in addition to the technology and basic knowledge acquisition) will be devoted to the promotion of a wider knowledge on multifunctional structures and devices to a broad community, including companies or policymakers. The success of the project will depend on the ability to stimulate public interest to multifunctional thin-film structures with radically new properties. The planned dissemination activities (such as data bank, public website, issuing brochures, public lectures) are detailed in the following sections.
