Electrochemical energy conversion devices such as fuel cells (FCs) and water electrolyzers (WE) have attracted attention from the scientific community for their unique ability to store electrical energy in the form of hydrogen and then generate electricity by the reverse process. Unfortunately, those devices rely on a significant amount of …

In optimization, it is well known that algorithm performance is dependent on the problem being solved. As a consequence of this, achieving good optimization results requires correctly matching an optimization problem to a specific optimization algorithm that performs well on that problem. For this to be possible, knowledge of both …

Research and development of exoskeletons for injury prevention and assistance with everyday living has steadily increased in the last decade. With some products already available on the market, a widespread adoption of exoskeletons appears to be within close reach. However, many challenges still remain to be overcome, one of which …

In the past, the search for soluble aluminium trifluoride (AlF3) led to the discovery of organoaluminium compounds (AlR3) and organoaluminium fluorides. However, suitable methods for the introduction of fluorine into AlR3 are still scarce, making the discrete AlF3 and organoaluminium fluoride compounds rare. Our investigation of the reactivity of cyclic …

Time-of-flight secondary ion mass spectrometry using MeV ions (MeV ToF SIMS) has been around for a few decades as a reliable, surface-sensitive method for the detection of molecular ions having masses up to 1000 Da. It provides excellent lateral resolution of a few μm for imaging of organic samples, making …

Alkali activation is a chemical process in which aluminosilicate-rich materials that dissolve in basic media at room temperature form binding phases by polycondensation. Alkali-activated materials (AAM), also called geopolymers, are inorganic aluminosilicate-based materials produced mainly from fly ashes and metallurgical slags or clays with high Al and Si content and …

This thesis focuses on the fate of chosen antidepressants in the environment. Studied compounds belong to the class of selective serotonin reuptake inhibitors. Reportedly they do not completely mineralize by existing water treatment processes and their residues cause unwanted toxic effects in aquatic organisms. However, to date, insufficient information has …

The miniaturization of electronic devices requires the fabrication of functional components in the form of μm-sized thick films. Some of the most promising functional materials are relaxor-ferroelectric (1-x)Pb(Mg1/3Nb2/3)O3–xPbTiO3 (PMN–100xPT), as they exhibit versatile dielectric, piezoelectric and relaxor-ferroelectric properties. However, the integration of functional ceramic thick films with non-conventional substrates such …

Human knowledge about food and nutrition has evolved drastically with time. With food and nutrition-related data being mass produced and easily accessible, the next step is to use Artificial Intelligence (AI) to translate data into knowledge. The majority of AI research is model-driven, and classical Machine Learning (ML) pipelines concentrate …

The link between TiO2 and photocatalysis was recognized a long time ago. However, there was originally no scientific knowledge relating to the process of photocatalysis. Given this, it is impressive that the most significant advances in the properties of TiO2 in photocatalytic processes have been made since the first reports …
