Raap, Caspar (author), van der Vlist, Deborah (author), Kooiker, Jasper (author), Julia Sumarthinningrum Dahlan, Julia (author), Duan, Yu (author)The Netherlands has created a large nitrogen pollution problem in its soils, which is harming biodiversity. By intensifying and industrialized farming, by importing animal feed for dairy production and fertilizer for crop farming, too much nitrogen has accumulated in the soil. Consequently, ecological processes are disturbed due to...student report 2024

Zhu, Z. (author), Zhang, Y. (author), Min, Changjun (author), Adam, A.J.L. (author), Urbach, Paul (author), Yuan, Xiaocong (author)Optical tweezers have proved to be a powerful tool with a wide range of applications. The gradient force plays a vital role in the stable optical trapping of nano-objects. The scalar method is convenient and effective for analyzing the gradient force in traditional optical trapping. However, when the third-order nonlinear effect of the nano...journal article 2024

Sepúlveda Hernández, Estefanía (author), Nguyen-Minh, Tuan (author), Traka, K. (author), Castro Cerda, Felipe (author), Kestens, L.A.I. (author)This study investigates the sub-structure of IF steel in three conditions: cold rolled, statically recovered, and warm rolled. After both cold and warm rolling, the steel exhibits the typical 〈110〉//RD and 〈111〉//ND fiber textures. Considering the short-range misorientation gradient ∆θ/∆x to assess locally stored energy variations, it was...journal article 2024

van Wiechen, P.P.J. (author), de Vries, S. (author), Reniers, A.J.H.M. (author)During extreme conditions, the transport of the wave-averaged suspended sediment concentrations in the inner surf zone affects dune erosion. Although large-scale laboratory experiments have provided insight in what drives these sediment concentrations, corresponding field data are lacking. To fill this gap, novel field observations of suspended...journal article 2024

Besseling, Roos (author)This study investigates the capacity of an open inverted filter to stabilize the interface between the sand fill and core fill in a rubble mound breakwater. The strength of this filter relies on the arching mechanism of the base material, which is directly influenced by factors such as stability ratio and effective stresses. These forces arise...master thesis 2023
