Lubelli, B.A. (author), des Bouvrie, E. (author), Nijland, T.G. (author), Kamat, A. (author)Salt crystallization is a major cause of weathering of mortars, including plasters and renders. In the last decade, the use of mixed-in salt crystallization inhibitors in mortars has been proposed as a solution to improve the durability of this material with respect to salt decay. Laboratory characterization and accelerated weathering tests have...article 2023

(author), Farha, O.K. (author)In the case of an incident with nerve agents, the timely and ready detection and identification of such a substance on suspected surfaces is essential. However, the detection of low levels of nerve agents on a surface is a considerable challenge for conventional detection equipment, especially with VX, a highly toxic nerve agent with low...article 2022

(author)The low throughput of atomic force microscopy (AFM) is the main drawback in its large-scale deployment in industrial metrology. A promising solution would be based on the parallelization of the scanning probe system, allowing acquisition of the image by an array of probes operating simultaneously. A key step for reaching this goal relies on the...article 2021

(author)When a droplet is brought in contact with an undercooled surface, it wets the substrate and solidifies at the same time. The interplay between the phase transition effects and the contact-line motion, leading to its arrest, remains poorly understood. Here we reveal the early solidification patterns and dynamics of spreading hexadecane droplets....article 2021

Paap, B. (author), Kraaijpoel, D. (author), Wassing, B. (author), van Wees, J.D. (author)Numerical simulations of seismic wave propagation usually rely on a simple source modelconsisting of an idealized point location and a moment tensor. In general, this is a validapproximation when the source dimensions are small relative to the distance of points at whichthe seismic wave motions are to be evaluated. Otherwise, a more realistic...article 2020

Granneman, S.J. (author), Lubelli, B.A. (author), van Hees, R.P.J. (author)Weathering of porous building materials caused by the crystallization of soluble salts is a ubiquitous problem in the built cultural heritage. Especially lime-based mortars are susceptible to salt decay, due to both their bimodal pore size distribution and low mechanical strength. The addition of crystallization modifiers to mortars during...article 2019
