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.

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.

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.
In this research proposal, four clear and timely questions / problems have been set that will lead us to new directions. They are challenges from a mathematical point of view, as well as from a physical point in directions related to Physics of higher dimensions at finite temperatures, Crystallography issues about hyperbolic crystals and radiation scattering theories by introducing a Generalized Bragg Law and mathematical innovations that will help us to understand the properties of Clausen and Bloch-Wigner-Ramakrishnan functions.

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.

This research focuses on the study and implementation of instrumentation systems for earthquake monitoring, with modern commercial sensors, and modern instrumentation algorithms. Individual goals consist the optimal acquisition of linear acceleration characterized by low signal-to-noise ratio and low frequency and the development of an instrumentation system with modern power consumption behavior and with advanced embedded processing, storage and communication functionality.

The research proposal by Dr Maria Elissavet Koukouli aims to optimize the current capabilities of existing air quality forecasting models by using satellite atmospheric monitoring data to provide regularly updated emission inventories for air pollutants over Europe.
In the framework of postdoctoral research, the environmental impact of road transport is studied with an integrated computational tool that connects individual models and methodologies to assess all the significant variables that characterize the quality of the atmospheric environment, such as pollutant emissions, carbon footprint, traffic noise, energy efficiency, simulated while taking into account the atmospheric flow in the boundary layer and the real-world traffic conditions.

The objective of this postdoctoral research is the study and design of antennas operating in mobile and wireless communication networks for RF energy harvesting applications. These antennas should meet several constraints regarding the reflection coefficient, input impedance, realized gain, size, and complexity. The antenna systems that will be designed in this research will operate in both outdoor and indoor environments.
The milestones of this postdoctoral research include the design of a) an antenna system operating in several frequency bands of the outdoor environment for RF energy harvesting applications and b) an antenna system operating in the Wi-Fi frequency band of the indoor environment for RF energy harvesting applications.
The current research is focused on developing techniques and algorithms
that can be applied for the automated and continuous near real time
monitoring of aerosol species profiles (e.g. dust, smoke, volcanic
ash), trace gas profiles (e.g. O3, NO2, HCHO) and cloud layers based on
the synergy of remote sensing instruments.
The objective of this study is the synthesis of inorganic nanomaterials by using raw materials originating from industrial by-products (mining and manufacture processes e.g. dolomitic marbles, wood residuals, whitestone, dyes, adsorbents) and their incorporation in added value innovative products oriented to gas or water treatment as well as to the direct feeding of large construction formation.
The proposed postdoctoral research aligned with the evolution of Wireless Energy Harvesting (W.E.Η.) technology, will focus on the synthesis of innovative RF energy harvesting antenna systems ("rectenna"), which will meet the required specifications, in order to power wireless sensors. The rectenna will include a novel antenna, a rectifier and a custom matching network.
