(author), Wang, Xiuqi (author), Pourandi, Sahar (author), Weinhart, Thomas (author)In this paper we introduce the open-source code MercuryDPM: a code for simulating discrete particles. The paper discusses software and management issues that may be interesting for the developers of other open-source codes. Then we review the new features that have been added since the last publication: an improved Hertz-Mindlin model; a new...journal article 2023

Stoeten, Victor (author)Floods and droughts, also known as hydro-hazards, are phenomena that generally involve detrimental consequences to society and environment. Traditional practices for risk assessment consider flood and drought independently. However, they are two opposite extremes of the same hydrological cycle. Omitting their interaction might lead to an under-...master thesis 2022

Stelling, G.S. (author)The widespread availability of high-resolution Digital Elevation Models (DEM), has led to the development of subgrid numerical modeling techniques, based on Shallow Water Equations (SWE). Detailed DEM data is clustered as much as possible within a coarse grid cell that is preferably much larger than a raster pixel. This has considerable...journal article 2022

Zhao, H. F. (author), Jommi, C. (author)Peats are encountered in waterlogged deltaic areas, where degradation is delayed by favourable environmental conditions. The recent increase in frequency and severity of droughts is expected to accelerate peat degradation, in turn increasing subsidence and flood risk, urging better understanding of the response of peats to drying events. To...journal article 2022

Sun, Renjuan (author), Lu, Wei (author), Tawfek, Abdullah M. (author), Guan, Yanhua (author), Hu, Xinlei (author), Zhang, Hongzhi (author), Ling, Yifeng (author), Šavija, B. (author)The resistance of cracked ECC against chloride ingress is mainly governed by the accumulated crack width of all the cracks rather than the maximum width of multiple cracks. However, most studies focus on the influence of a single fine crackjournal article 2022

Li, Wei (author), Yi, Liming (author), Jiang, Wen (author), Dong, H. (author), Zhang, Yong (author)This paper presents experimental investigations into the effects of ultrafine blast furnace slag on microstructure improvements against chloride penetration in saturated and unsaturated cementitious systems exposed to cyclic drying–wetting conditions. The hydration kinetics of ultrafine slag powders and pore solution chemistry in slag-blended...journal article 2022

Jongerius, Camiel (author)The study of adhesion mechanisms in animals such as the gecko has helped mankind with the understanding and development of novel adhesives. The adhesion mechanism of the tree frog is not fully understood, it is a wet adhesion mechanism which works differently than the dry adhesion mechanisms of animals, such as the gecko, studied previously. The...master thesis 2021

La Zara, D. (author)The majority of pharmaceutical products is made of solid powders. The morphology and surface characteristics of drug particles affect both their bulk behaviour, e.g., flowability, dispersibility and tabletability, in the manufacturing process of dosage forms as well as their bioavailability upon administration into the human body. For instance,...doctoral thesis 2021

Antonova, Anna (author), Eik, Marika (author), Punkki, Jouni (author), Jokinen, Ville (author), Puttonen, Jari (author)The performance of fibre reinforced cementitious composites depends on the interaction between the cementitious matrix and the fibres on the micro-scale. This interaction is affected by the material and surface properties of the fibre and the micro-scale characteristics of the cementitious matrix close to the fibre surface, creating the...conference paper 2021

Li, X. (author)A flexible riser is a multi-layered pipe device which enables deep-water production by connecting seabed facilities to floating vessels. To withstand huge hydro-static pressure, it is required to have strong collapse capacities. At present, the collapse capacity of a flexible riser is designed based on a "wet collapse'' concept, in which the...doctoral thesis 2021

(author)The wettability of pharmaceuticals is a key physical property which influences their dissolution rate, dispersibility, flowability and solid-state stability. Here, we provide a platform of surface nanoengineering methods capable of tuning the wettability of drug powders from high hydrophilicity to superhydrophobicity with drug loadings up to...journal article 2021

Varveri, Aikaterini (author), Jing, R. (author), Tarsi, G. (author), Erkens, S. (author)Moisture sorption can significantly influence hydrothermal ageing and alter the chemical and rheological properties of bituminous mastics. Mineral filler particles are added to bituminous binders to form mastics with increased stiffness. The addition of fillers can considerably change the moisture sorption and the physico-chemical properties...journal article 2021

Li, X. (author), Jiang, X. (author), Hopman, J.J. (author)Flexible risers are designed with strong anti-collapse capacities which enable them to operate in deep-water reservoirs. However, this anti-collapse capacity is susceptible to the pipe curvature in the flooded annulus condition. For the curved riser sections within the touch-down zone, significant reduction of collapse capacity can occur once...journal article 2021

(author)Crystalline silicon tandem devices with perovskites, CIGS, and nanocrystalline silicon, as well as the TOPCon design, are incompatible with the conventional pyramidal surface texture of silicon. This is a result of crack formation in nano to polycrystalline growth on large sharp surface features. In this work, three texturing approaches are...journal article 2021

Kothari, V.V. (author)Decarbonisation can be done through various routes: reducing the final energy consumption by improving process conditions and efficiency, reusing waste heat and by an outright energy transition to renewable sources. In this study, the focus is on reusing waste heat. Heat pumps have the potential to drastically reduce energy requirements in the...master thesis 2020
