The rapid evolution of sensor technologies, particularly within the Internet of Things (IoT) domain, has led to an era dominated by massive real-time data flows. This transition resulted in the need for novel data processing methodologies that facilitate the shift from traditional offline batch analytics to agile real-time predictions and …

This dissertation combines academic research and the application of its results to a real benchmark process. With the emerging electro-energetic systems that have a large share of renewable sources, hydrogen is becoming an important energy carrier that contributes to the storage and usage of surplus green energy and thus reduces …

Time-of-flight secondary ion mass spectrometry (ToF-SIMS) is a versatile analytical method widely used in the field of surface science and thin films. Although it gives elemental, molecular, and isotopic information, it has a very low detection limit and high lateral resolution, is fast and works with all the vacuum-compatible samples, …

We are witnessing major shifts in ecosystems due to intense anthropogenic pressures on the environment in recent decades, including rapid climate change, which is one of the strongest drivers of a global biological response. Raptors, which are at the top of the trophic web, are important indicators of ecosystem health. …

In the view of designing new nanostructured materials and tailoring their functional properties, understanding the nucleation and crystal growth mechanisms is becoming increasingly important. Nowadays, one of the most addressed scientific and social problems are those facing energy shortage and global warming. People started to realize the value and importance …

Plastic pollution is a global issue, yet our understanding of its impact on organisms and ecosystems remains limited. My PhD thesis explores the presence of microplastics (MP) in river ecosystems, their interaction with freshwater hyporheic biofilms and specifically, the response of hyporheic biofilms to polyethylene terephthalate (PET) pollution in the …

In recent decades, hydrogen peroxide (H 2 O 2 ) has attracted considerable attention as a n omnipresent analyte, finding applications in clinical studies/diagnos is , biology, environmental protection, atmospheric studies, homeland security, and various analytical methodologies . This dissertation provides valuable insights into three different types of electrochemical sensors …

Rising demands for food, instigated by population growth and urbanization, are calling for advanced agricultural approaches to increase crop yields. However, the expansion of food production should not come with an unmanageable environmental cost. Plant science is therefore challenged to provide sustainable innovations for combating the detrimental effects of unfavourable …

A paradigm shift is occurring in the assessment of exposure to urban environmental stressors. Improved accuracy of personal monitors has enabled researchers to study exposure at the individual level. Monitoring stations are the primary reference point for air quality in urban environments, although there is a need to assess exposure …

The analysis of drug residues in waste and environmental waters offers valuable insights into the epidemiological and environmental implications of drug use. This study employs a wastewater-based epidemiology (WBE) approach to estimate the use of licit and illicit drugs and new psychoactive substances (NPS) among both general and specific populations. …
