Systems with hidden attractors are called dynamical systems that are studied in regions far from equilibrium points. Hidden attractors are a modern field of research with great prospects. In our research we intend to expand the study of hidden attractions in three main directions: 1. Use of analytical methods. 2. Systems of higher dimensions. 3. Applications in mechanical systems and new areas of natural problems.

In this project, we are studying the dynamical lattice properties of 2D ferroelectric and topological materials, such as phonon effects, as well as electronic transport and optical conductivity. We are using high throughput techniques for handling the number of simulations. Our results open the route to the use of Machine Learning methods in ferroelectric materials research, a field that has been explored very little.

The research will focus on developing the epistemological awareness of secondary school students and pre-service student-teachers, regarding Scientific Models. In this context, the use of an inquiry based Teaching Learning Sequence (T.L.S.) based on Scientific Models is recommended. Through the use of the T.L.S. the aspects of Scientific Models are expected to be developed. The activities integrated in the T.L.S. include real and virtual experiments using Information and Communication Technologies (I.C.T.). The assessment of subjects’ epistemological awareness about the aspects of Scientific Models will be conducted with the use of research based questionnaires and semi-structured interview.

The main aim of this research is to develop the tools required to analyse high spatiotemporal resolution observations of atmospheric constituents sensed by instruments on a geostationary orbit, as well as to perform quality assessment and validation of these observations. Αir quality monitoring from geostationary orbits is a very recent development in the field rendering the extensive validation and analysis of these observations paramount. Since the Sentinel-4 UVNS instrument, which will cover the European domain, is due for launch in 2024, this study focused on the development of the necessary algorithms for the GEMS/KOMPSAT-B instrument, which observes the Asian domain from 2020 onwards.

The present research aims to study the phenomenon of Urban Heat Island (UHI) in the urban and suburban areas of the city of Thessaloniki. This will be achieved through the use of a densely distributed network of meteorological stations (>1 station per 1 km^2), which will be correlated with land use. Simultaneously, the residents' discomfort levels in various areas will be assessed. As the sea breeze mechanism is an integral part of the city's climatology, the intensity and extent of the sea breeze's impact will be investigated, along with its interaction with the UHI. Finally, an analysis of all the aforementioned mechanisms and phenomena will be conducted during heatwave episodes to identify areas with the highest and lowest levels of burden.

Aim of this research is to evaluate the NASA CloudSat products using ground-based measurements performed in ACTRIS stations. Combined ground-based lidar-radar observations performed in the framework of the PRE-TECT experiment during April 2017 at the Greek Atmospheric Observatory are used to evaluate the CloudSat performance in detecting hydrometeors. Moreover, ground-based lidar measurements performed with THEssaloniki’s Lidar SYStem will be used for evaluating CloudSat performance in detecting ice crystals clouds.The outcome of this work is a step towards the use of CloudSat products for performing a decade-long cloud statistical analysis over the poorly studied East Mediterranean region and to evaluate the upcoming EARTHCARE algorithms and cloud products.

The goal of this project is to study the full carbon cycle in relation to the atomic-to-molecular transition in different environments of the interstellar medium and understand its properties in the low- and high- redshift Universe. The main objective is to fully investigate the utilities of the ionized and atomic carbon as accurate and alternative tracers of the molecular gas in the wider context of extragalactic observations. We will also build an online interactive platform and a publicly available database consisting of the outputs of this project.

Hitherto unprecedented detections of exoplanets have been triggered by missions and ground based telescopes. Dynamical studies can help ascertain information regarding the neighbourhood of exoplanets. In particular, the periodic orbits can lead to the identification of the regular domains in the phase space, where the long-term stability and hence, the survival of exoplanets can be guaranteed. Guided by the stable periodic orbits, we unveil such boundaries via maps of dynamical stability and either validate or constrain the observational data, which are oftentimes given with large deviations.

We study the dynamics of Kuiper—belt objects which are located in exterior mean motion resonances with Neptune and they have been observed at very high inclination (i>90°). The basic model is the restricted 3-body problem. We find planar and three—dimensional retrograde periodic orbits and study their stability type. We shall produce dynamical stability maps in the diagrams a—e or i—e in order to study the phase space structure of the above resonances. Our survey will be continued to the asteroid belt.

Our main objective is to study how neutron star oscillations and tidal effects in neutron star binaries influence the gravitational-wave emission and the neutron star evolution, in order to obtain information about the (otherwise inaccessible) neutron star interior, i.e., about the dense nuclear matter equation of state. The role of nonlinear interactions among stellar oscillation modes and their implications are the main focus of this study.

Two- dimensional (2D) materials (graphene, TMDCs) have attracted attention recently due their unique physical properties. Doping and mechanical strain in 2D materials is a strategy to precisely control their electronic and optical properties, without causing any induced structural disorder. The sinngle and few layer 2D materials are grown by CVD method and are mainly investigated by Raman spectroscopy.

Measurement of specific loss power (SLP) of magnetic nanoparticles is crucial to assert the heating potential in magnetic hyperthermia. In this work, we propose a step by step standardization protocol, starting from definition and recording of potential uncertainty and error sources, present during a typical magnetic hyperthermia experimental protocol. The error of each specific parameter is estimated and translated to ultimate heating efficiency evaluation. All parameters involved in the heating efficiency evaluation and their associated uncertainties analysis presented in this work, are included in a standardization protocol, a handy guideline for determining accurate, reliable and reproducible SLP values, thus adequately evaluating its impact in potential bioapplications.

In this work we address Magnetic Particle Hyperthermia, an alternative cancer treatment, based on the heat released by magnetic nanoparticles whenever subjected to Alternating Magnetic Field. The samples are prepared by coprecipitation aqueous method, while a further post-synthetic step includes their 3D assembly in linear chains under the guidance of a bias static field inside an agarose matrix that mimic tissue features as a tool to optimize their heating efficiency

Focusing on the development of additive-reinforced composites is undoubtedly a particularly attractive prospect for manufacturing multifunctional materials. The combined exploitation of the advantages of the individual elements of composite materials is expected to lead to the creation of materials with targeted properties and excellent performances, giving them a high added value, as requested by both research and industry on a global scale. Therefore, this thesis aims to measure, understand, model, and predict the effect of realistic processing conditions on polymer matrix properties.
