(author), Wagemaker, M. (author), Eichel, Rüdiger A. (author)High-fidelity and facile ex situ transmission electron microscopy (TEM) characterization of lithium−oxygen (Li−O<sub>2</sub>) batteries is still limited by challenges in preserving the native environment of Li−O<sub>2</sub> discharge products. The extreme reactivity and moisture sensitivity of the discharge products means that they are...journal article 2020

(author), Copuroglu, Oguzhan (author)Water to cement (w/c) ratio is usually the most important parameter specified in concrete design and is sometimes the subject of dispute when a shortfall in concrete strength or durability is an issue. However, determination of w/c ratio in hardened concrete by testing is very difficult once the concrete has set. This paper presents the...journal article 2020

van Kessel, L.C.P.M. (author), Huisman, T. (author), Hagen, C.W. (author)Line-edge roughness (LER) is often measured from top-down critical dimension scanning electron microscope (CD-SEM) images. The true three-dimensional roughness profile of the sidewall is typically ignored in such analyses. We study the response of a CD-SEM to sidewall roughness (SWR) by simulation. We generate random rough lines and spaces,...conference paper 2020

Filius, M. (author), Cui, T.J. (author), Ananth, A.N. (author), Docter, M.W. (author), Hegge, Jorrit W. (author), van der Oost, John (author), Joo, C. (author)Super-resolution imaging allows for the visualization of cellular structures on a nanoscale level. DNA-PAINT (DNA point accumulation in nanoscale topology) is a super-resolution method that depends on the binding and unbinding of DNA imager strands. The current DNA-PAINT technique suffers from slow acquisition due to the low binding rate of...journal article 2020

Cichocka, M.O. (author), Bolhuis, M. (author), van Heijst, S.E. (author), Conesa Boj, S. (author)Layered materials (LMs) such as graphene or MoS2 have attracted a great deal of interest recently. These materials offer unique functionalities due to their structural anisotropy characterized by weak van der Waals bonds along the out-of-plane axis and covalent bonds in the in-plane direction. A central requirement to access the structural...journal article 2020

(author)Pulsed laser beam welding was used successfully to join the oxide dispersion-strengthened (ODS) Eurofer steel. The joining was conducted with a laser power of 2500 W and a pulsed duration of 4 ms. With the filler material being used, a minor material loss and microvoids were observed in the joint. The microstructure of the fusion zone...journal article 2020

(author)We investigated the characteristics of a group of 13 Middle Iron Age egg-shaped crucibles and crucible fragments from Tilburg (The Netherlands). We used a combination of optical and chemical analyses, including hand-held XRF, microCT scanning and 3-D printing polarizing light microscopy and SEM-EDX. The chemical analyses confirmed that the...journal article 2020

Kabiri, Y. (author)The low contrast of biomolecules in TEM has been a great obstacle for their structure determination and hence to the understanding of their structure-function relation. Historically, single DNA strands remained one the most difficult classes of biomolecular specimens to image, due to low electron scattering strength of its constituent elements....doctoral thesis 2019

(author)A seventeenth-century canvas painting is usually comprised of varnish and (translucent) paint layers on a substrate. A viewer’s perception of a work of art can be affected by changes in and damages to these layers. Crack formation in the multi-layered stratigraphy of the painting is visible in the surface topology. Furthermore, the impact of...journal article 2019
