van der Veen, J.R. (author), Valianti, S. (author), van der Zant, H.S.J. (author), Blanter, Y.M. (author), Meysman, F.J.R. (author)The recent discovery of cable bacteria has greatly expanded the known length scale of biological electron transport, as these multi-cellular bacteria are capable of mediating electrical currents across centimeter-scale distances. To enable such long-range conduction, cable bacteria embed a network of regularly spaced, parallel protein fibers...journal article 2024

(author), van der Veen, M.A. (author)In order to capture and separate CO2 from the air or flue gas streams through nanoporous adsorbents, the influence of the humidity in these streams has to be taken into account as it hampers the capture process in two main ways: (1) water preferentially binds to CO2 adsorption sites and lowers the overall capacity, and (2) water causes...journal article 2023

(author), Reinsch, Helge (author), Shupletsov, Leonid (author), Markey, Karen (author)Several metal–organic frameworks (MOFs) excel in harvesting water from the air or as heat pumps as they show a steep increase in water uptake at 10–30 % relative humidity (RH%). A precise understanding of which structural characteristics govern such behavior is lacking. Herein, CAU-10-H and CAU-10-CH<sub>3</sub> are studied with -H, -CH<sub>3...journal article 2023

(author), Smolentsev, Grigory (author), Repo, Eveliina (author), van der Veen, M.A. (author)Titanium-based metal-organic framework, NH2-MIL-125(Ti), has been widely investigated for photocatalytic applications but has low activity in the hydrogen evolution reaction (HER). In this work, we show a one-step low-cost postmodification of NH2-MIL-125(Ti) via impregnation of Co(NO3)2. The resulting Co@NH2-MIL-125(Ti) with embedded single...journal article 2023

Veldhuizen, H.V. (author), van der Zwaag, S. (author), van der Veen, M.A. (author)Flow-induced disturbances were applied during the synthesis of a naphthalene diimide covalent organic framework (NDI-COF), which resulted in different COF polymer networks. We discovered that a high intensity of stirring resulted in more aggregated structures on both the micro- and nano-length scale. Subsequently, these structures absorbed...journal article 2022

Kazaz, T. (author), Janssen, G.J.M. (author), Romme, J.P.A. (author), van der Veen, A.J. (author)In wireless networks, an essential step for precise range-based localization is the high-resolution estimation of multipath channel delays. The resolution of traditional delay estimation algorithms is inversely proportional to the bandwidth of the training signals used for channel probing. Considering that typical training signals have...journal article 2022

Keshavarz, Fatemeh (author), Kavun, V. (author), van der Veen, M.A. (author), Repo, Eveliina (author), Barbiellini, Bernardo (author)Selective separation of rare earth elements (REEs) from solutions of mixed heavy and light metals by solid adsorbents is an important challenge in the fields of water treatment and metal recovery. The main challenge is water instability of many adsorbents, specifically metal–organic frameworks (MOFs), and their low selectivity. Grafting...journal article 2022

Roosen, M.A. (author), Yang, Y. (author), van der Veen, C. (author), Schaafsma, Dick G. (author), Hendriks, M.A.N. (author)When the shear resistance of prestressed beams with stirrups is determined with the current Eurocode, no distinction is made between regions with and without flexural cracks. This while it may be expected that a region without flexural cracks will have a higher shear resistance. This is due to the lower longitudinal strains and the narrow...journal article 2022

Mula, S. (author), Donà, Lorenzo (author), Civalleri, Bartolomeo (author), van der Veen, M.A. (author)Metal-organic frameworks (MOFs) are a class of nanoporous crystalline materials with very high structural tunability. They possess a very low dielectric permittivity ϵr due to their porosity and hence are favorable for piezoelectric energy harvesting. Even though they have huge potential as piezoelectric materials, a detailed analysis and...journal article 2022

Lantsoght, E.O.L. (author), Yang, Y. (author), van der Veen, C. (author)Load testing and in some cases failure (or collapse) testing of bridges is a method to learn more about the behaviour of full-scale bridges in site conditions. Since such experiments, especially failure tests, are expensive, an extensive preparation of these tests is important. This paper addresses the question of when a bridge is a good...journal article 2022
