Six, Pascale (author)Plastic is one of the major pollutants in the world and currently, more than 300 million tons of plastic are produced worldwide (Miandad et al. 2019). Since only 9.5% of plastic waste is being recycled, littering has caused a lot of non-recyclable plastics (NRP) that wander around damaging the environment and ending up in landfills, oceans and...master thesis 2024

Hussein, Abdelrahman (author), van der Zwaag, S. (author), Kim, Byungki (author)In recent years, a new class of super saturated binary and ternary alloys have demonstrated the ability for the self-healing of creep-induced voids formed at the grain boundaries. However, a clear understanding of the parameters affecting the self-healing mechanism is still not yet complete. One of the main challenges is understanding the...journal article 2024

Bos, P. (author), Ritzen, L. (author), van Dam, S.S. (author), Balkenende, R. (author), Bakker, C.A. (author)Replacing fossil-based feedstock with renewable alternatives is a crucial step towards a circular economy. The bio-based plastics currently on the market are predominantly used in single-use applications, with remarkably limited uptake in durable products. This study explores the current state of the art of bio-based plastic use in durable...journal article 2024

de Jong, S.D.M. (author), Ghorbani Ghezeljehmeidan, A. (author), van Driel, W.D. (author)The ability to accurately predict the reliability and lifetime of electronics is of great importance to the industry. The failure of the solder joint is of particular interest for these predictions, because of their susceptibility to failure under thermo-mechanical stress. However, the experimental or even conventional simulation techniques...conference paper 2024

Ke, L. (author), van der Meer, F.P. (author)Numerical methods for delamination analysis, such as the cohesive zone method, require fracture energy as an essential input. Existing formulations rely on a phenomenological relationship that links fracture energy to the mode of fracture based on linear elastic fracture mechanics (LEFM). However, doubts exist about the applicability of LEFM....journal article 2024

Magherini, A. (author), Yan Toe, C. (author), Stancanelli, L.M. (author), Wüthrich, D. (author), Uijttewaal, W.S.J. (author)Plastic pollution is a threat for all ecosystems due to its effects on people, animals, and environment (Mai et al., 2020). Rivers are estimated to transport around 0.5 millions tons of plastic per year (Strokal et al., 2023). When plastic enters a river system, it is transported downstream towards the sea but it is also likely to accumulate at...abstract 2024

Storm, J. (author), Rocha, I.B.C.M. (author), van der Meer, F.P. (author)Simulating the mechanical response of advanced materials can be done more accurately using concurrent multiscale models than with single-scale simulations. However, the computational costs stand in the way of the practical application of this approach. The costs originate from microscale Finite Element (FE) models that must be solved at every...journal article 2024

Li, Kai (author), Ward, Hauke (author), Lin, H.X. (author), Tukker, Arnold (author)The global trade of plastic waste has raised environmental concerns, especially regarding pollution in waste-importing countries. However, the overall environmental contribution remains unclear due to uncertain treatment shares between handling plastic waste abroad and domestically. Here, we conduct a life cycle assessment of global plastic...journal article 2024
