We demonstrate that changes in the unit cell structure of lithium battery cathode materials during electrochemical cycling in liquid electrolyte can be determined for particles of just a few hundred nanometers in size using in situ transmission electron microscopy (TEM). The atomic coordinates, site occupancies (including lithium occupancy), and cell parameters of the materials can all be reliably quantified. This was achieved using electron ...

In the era of rapidly changing natural environments, there is an urgent need for understanding biodiversity-ecosystem functioning. Trophic interactions play a key role in structuring the ecosystem. In marine systems, the feeding ecology of the larger-sized species i.e. (top) predators of food webs, is fairly well documented, yet at the basal level of food webs, the complexity of grazer interactions is much higher and trophic linkages are ...

In recent years, the agrifood sector faced many global challenges, where climate issues are emerging, food insecurity and economic instability are increasing due to the ongoing pandemic (COVID-19), and geopolitical instability, including military conflicts. Furthermore, globalization of the food market caused the enormous growth of the food supply chain, where industrialized food processing generates significant amounts of residues and ...

La Trypanosomiase Humaine Africaine (THA) ou maladie du sommeil est une pathologie parasitaire provoquée par un protozoaire du genre Trypanosoma. Ce parasite est transmis à l’homme par la piqûre de la glossine, la mouche tsétsé. Deux sous-espèces de trypanosome sont pathogènes pour l’homme: le T. brucei gambiense et le T. brucei rhodesiense. L’Organisation Mondiale de la Santé (OMS) considère la THA comme une des Maladies Tropicales ...

Once marketed, drugs may suffer from suboptimal performance as they are often taken with meals and/or beverages not accounted for during clinical trials. Any ingested formulation will initially reside in the stomach where exposure to a variety of internal (e.g. pH and motility) and external factors (e.g. co-administration of beverages and foods) potentially influences intragastric formulation disintegration and drug dissolution. As this ...

After decades of intense research, insight in zeolite nucleation and crystal growth remains limited. By investigating zeolite formation in hydrated silicate ionic liquids (HSIL), this PhD intends to shed new light on zeolite crystallization. Unlike other synthesis strategies, HSIL synthesis enables zeolite crystallization from a controlled liquid, a model system that is compatible with most characterization tools. Molecular investigation reveals ...

Many investigations are dedicated to the detection and quantification of reactive oxygen and nitrogen species (RONS), particularly when generated in liquids exposed to cold atmospheric plasmas (CAPs). CAPs are partially ionized gases that can be obtained by applying a high electric field to a gas. A challenge is to get better insights on the plasma-liquid interactions in order to understand the induced effects on different targets (liquid, ...

Gas injection reactors in general, and bubble column reactors in particular, are key elements of many pyrometallurgical flow charts. Nevertheless, the phenomena and interactions that govern these reactors are not yet fully understood. From a multiscale point of view, the main bottleneck is situated at a mesoscopic level on which individual bubbles are considered. While simulations and water models can be very helpful to widen this bottleneck, ...

In an attempt to halt the drastic accumulation of carbon dioxide (CO2) in the atmosphere, many countries have agreed to implement industrial solutions for CO2 capture, storage and utilisation. The primary objective is to separate CO2 from water vapour and nitrogen exhaust streams of combustion industries by using established techniques, such as chemical absorption (amine scrubbing), physical adsorption, and cryogenic distillation. While these ...
