Interplay of bacterial endotoxins and transition metals in the inflammatory capacity of airborne particulate matter. University of Antwerp

Sarah Lebeer
Environmental Ecology & Applied Microbiology (ENdEMIC)
Urbanization has resulted in health-threatening concentrations of air pollutants like particulate matter (PM), a diverse and complex mixture of air-suspended particles. PM affects more people than any other pollutant, and can be associated with e.g.asthma exacerbations and heart and vascular diseases. Studies indicate that many of the observed health effects are related to the capacity of inhaled PM to induce airway inflammation. Although not ...

Evaluation of the capabilities of isotopic analysis of the essential transition metals Fe, Cu and Zn in whole blood and blood serum for medical diagnosis Ghent University

Frank Vanhaecke
Department of Chemistry, Department of Internal medicine, Department of Analytical chemistry

Chromatographic isolation of the essential transition metals Fe, Cu and Zn from whole blood or blood serum for their subsequent isotopic analysis via MC-ICP-MS (multi-collector ICP – mass spectrometry). Comparison of results for a reference population with those for patient groups for evaluation of the diagnostic capabilities of isotopic analysis in this context. Targeted diseases include hemochromatosis, Crohn’s disease, Wilson’s disease and ...

Minority-site occupancy of transition metals in dilute magnetic semiconductors. KU Leuven

André Vantomme
Nuclear and Radiation Physics
In a dilute magnetic semiconductor (DMS), magnetic atoms (or impurities) replace a few percent of the atoms of an otherwise non-magnetic semiconductor. For almost two decades, the co-existence of ferromagnetism and semiconducting behavior in some DMS materials has generated fundamental new physics and enabled the study of phenomena of interest for spin electronics (spintronics). However, despite such intense research, DMS materials are still far ...

Electrodeposition of metals, alloys and composite materials from acetamide-dimethyl sulfone eutectic melts KU Leuven

Koen Binnemans
Molecular Design and Synthesis, Surface and Interface Engineered Materials
The aim of this PhD thesis is the study of a new eutectic melts based on acetamide and dimethyl sulfone for the electrodeposition of metals, alloys and composites.
Mixtures of acetamide and dimethylsulfone (DMSO2) with dissolved anhydrous transition metal chlorides are introduced as new non-aqueous electrolytes for the preparation of luminescent composite metal coatings. Red-emitting (Eu2O3 and Y2O3:Eu3+), yellow-emitting (Y3Al5O12:Ce3+), ...

Non-Noble Metal Catalysis: research of the noble metals (Ru, Os, Rh, Ir, Pd, Pt) KU Leuven

Jeremy Harvey
Quantum Chemistry and Physical Chemistry

Transition metal catalysts are formidable tools towards greener chemistry, allowing for low-waste, energy-efficient, and selective reactions. However, the noble metals (Ru, Os, Rh, Ir, Pd, Pt) that are currently most common in homogeneous catalysts suffer from high toxicity and environmental impact in addition to their scarcity and ensuing high cost. First-row metals (Mn, Fe, Co, Ni, Cu) are emerging as environmentally benign alternatives, ...

Functionalized chitosan-silica hybrid materials for the recovery of critical metals from diluted aqueous waste streams. KU Leuven

Koen Binnemans
Molecular Design and Synthesis

Critical metals are defined as economically important metals with a high supply risk. On one hand, their availability is essential for the production of high-tech and green-tech applications, in turn crucial to enable the transition towards a low-carbon economy. On the other hand, their supply is vulnerable to geopolitically or economically driven fluctuations, since the market of technological metals is dominated by only a handful of ...

Mechanical assessment of metals after gaseous hydrogenation. Ghent University

Kim Verbeken
Department of Electromechanical, Systems and Metal Engineering, Department of Materials, Textiles and Chemical Engineering

Hydrogen gas is currently considered as the best potential replacement for fossil fuels, during the ongoing energy transition. However, the interaction between hydrogen and metals results in unpredictable material failure. Via the requested technologically advanced equipment, the specific characteristics of this interaction can be analysed, both on a microstructural, as on a macroscopic level to evaluate the materialU+2019s mechanical ...

Solvometallurgy for critical metals KU Leuven

Koen Binnemans
Molecular Design and Synthesis

The recent “rare-earth crisis” has brought about the widespread realisation that the long-term availability and cost stability of many materials – not just the rare earths – can no longer be guaranteed. Increasing the levels of critical metal recycling from pre-consumer, manufacturing waste and complex, multicomponent end-of-life consumer products is considered as arguably the most important and realistic mitigation strategy. However, ...
