Jolly, Mark (author), Katgerman, L. (author)Over the last 4 decades, remarkable progress has been made in the modelling of casting processes. The development of casting models is well reflected in the proceedings of the 15 Modelling of Casting, Welding and Advanced Solidification Processes (MCWASP) conferences that have been held since 1980. Computer simulations have enabled a better...journal article 2022

van Ginkel, H.J. (author), Vollebregt, S. (author), Schmidt-Ott, A. (author), Zhang, Kouchi (author)A method is presented to directly measure the mass output of an impaction printer coupled with a spark ablation generator. It is based on a quartz crystal microbalance and shown to be reliable in quantifying mass deposition rate. Here, the method is demonstrated with an Au nanoparticle aerosol synthesized under several spark ablation and...journal article 2022

Ammerlaan, Tim (author)Lithium-ion batteries are currently most commonly used in most electronic devices. These batteries are used because of their superiority in gravimetric energy and cyclability compared to other battery technologies. The most common anode used in lithium-ion batteries is currently graphite. Graphite has proven to be a very stable cycling material....master thesis 2021

Zaaijer, Floris (author)Mechanical air entrapment, void compression and void dissolution are the main mechanisms behind void formation in liquid composite molding. Mechanical air entrapment is induced by the highly non-uniform geometry at the meso- and micro-scale and the heterogeneous properties of the reinforcing material. This results in differences in the velocity...master thesis 2021

Gani, Siri (author)Energy storage is a critical component in decreasing the unpredictability of<br/>renewable energy. Silicon-air battery is a type of storage technology that potentially has a higher energy density than lithium-ion battery. The silicon-air<br/>battery, on the other hand, must overcome corrosion and passivation reactions in order to discharge...master thesis 2021

Corvi, Enrico (author)Among the many cities that lost their status of capital with the Italian unification, Naples is the one that struggled the most to reconcile with its past. With the cholera outbreak of 1874 the criticalities of centuries of uncontrolled urban development under foreign kings rose to the fore of the public opinion of the Kingdom of Italy. Yet, for...master thesis 2021

Kramer, O.J.I. (author)In drinking water treatment plants, multiphase flows are a frequent phenomenon. Examples of such flows are pellet-softening and filter backwashing where liquid-solid fluidisation is applied. A better grasp of these fluidisation processes is needed to be able to determine optimal hydraulic states. In this research, models were developed, and...doctoral thesis 2021

Oesch, Tyler (author), Weise, Frank (author), Marx, Heidi (author), Kositz, Mario (author), Huenger, Klaus-Juergen (author)Intensified Alkali-Silica Reaction (ASR) damage has occurred on German roadways in recent years, leading to requirements for compulsory pre-construction investigation of aggregate alkali sensitivity using concrete tests with external alkali supply. However, since these tests are time-consuming and cost-intensive, there is interest in replacing...conference paper 2021

Xu, Zhenhai (author), Gao, Jianming (author), Chen, Fei (author)Cement-based materials in sulfate rich areas will suffer from serious corrosion after semi-immersion. To study the degradation of cement mortars with different water cement ratio (w/c) partially exposed to sulfate solution, the mass change were employed to reveal damage progress. Moreover, porosity, erosion products and SO2 4 - content were...conference paper 2021

Chen, X. (author), Sanchez, T. (author), Conciatori, D. (author), Chaouki, H. (author), Sorelli, L. (author), Selma, B. (author), Chekired, M. (author)This paper presents a new 2D water transport model considering capillary suction to predict the water content evolution in the concrete porosity. The basic formulations of the model are illustrated, and a switching algorithm is introduced to simulated wet-drying effects. Two specific absorption tests are studied to validate this model. The first...conference paper 2021

Mendonck, Michiel (author)Comets are celestial objects that are thought to have formed at the outer edges of our solar system. The ices they contain is thought to be preserved since their formation in the molecular cloud phase, before the formation of the sun. The formation of ices in the molecular cloud occur via the ice mantle accretion rocess, by condensation of...master thesis 2021
