The imperative of reliability of biomedical implants is crucial to ensure their long-term functionality, thereby reducing the need for additional, sometimes invasive, surgical interventions. In this context, growing rods used to correct scoliosis in growing children face challenges related to a high fatigue failure rate.

Metal stents to treat arterial diseases of older humans are routinely designed and developed using young disease-free animals. Such animal models are used despite the significant declines of tissue regeneration, cell proliferation, and inflammation in aged humans and the profound cellular and structural changes present in diseased arteries that are not reflected in young healthy animals.

Lignocellulosic biomass gasification is a promising sustainable alternative to fossil fuels in several applications, such as high-temperature industrial heat for industries or decentralized and flexible Combined Heat and Power (CHP).

Due to climate change, the Belgian forests are under pressure and their health is becoming a major concern. For the moment, the forest parcels contain mostly a unique wood species presenting high density suitable for structural applications.

Interest in the space debris proliferation has been growing substantially over the last decade because of the ever-increasing threat posed by those derelict spacecrafts on the sustainability of future space activities and the risks for on-ground casualties and the environment.

Membranes are versatile materials, capable of achieving much in a small package. They have been widely explored for CO2 capture applications to enhance capture performance.

This thesis is dedicated to the exploration of natural convection phenomena within domains characterized by a heat-generating porous matrix immersed in a pure-fluid region.

Sofiane Benhamadouche will start by an overview showing the wide range of Reynolds and Rayleigh numbers which might encountered in the nuclear industry and thus the need of different approaches to model turbulence. A first part will be dedicated to advanced RANS (Reynolds Averaged Navier Stokes) modeling through second moment closures for both the dynamic and the thermal fields.

The new Thalos TEM microscope will very soon be installed in our premises. If we want to effectively use this brand-new instrument from day 1, we should start thinking of the experiments to perform with it. In this lecture, I will first present you in details what are the different possibilities offered by the instrument, the different optical modes and its ultimate performances.

Green hydrogen, produced from water electrolysis using renewable electricity, can decarbonize certain sectors such as the cement, steel, and fertilizer industries; long-haul shipping, aviation and cargo road transportation; and store and transport renewable energy.
