Kievits, A.J. (author), Duinkerken, B. H.Peter (author), Fermie, Job (author), Lane, R. (author), Giepmans, Ben N.G. (author), Hoogenboom, J.P. (author)Recent advances in electron microscopy techniques have led to a significant scale up in volumetric imaging of biological tissue. The throughput of electron microscopes, however, remains a limiting factor for the volume that can be imaged in high resolution within reasonable time. Faster detection methods will improve throughput. Here, we have...journal article 2024

Saravanakumar, Karthikeyan (author)The chemistry of ground granulated blast furnace slag (GGBFS) is one of the main factors affecting its reactivity. Knowing the composition of GGBFS used in aged concrete may help understand its past performance and estimate remaining service life. It is well known that GGBFS generally react slower than cement clinker. This thesis proposes that...master thesis 2023

Lane, R. (author), Wolters, Anouk H.G. (author), Giepmans, Ben N.G. (author), Hoogenboom, J.P. (author)Volume electron microscopy (EM) of biological systems has grown exponentially in recent years due to innovative large-scale imaging approaches. As a standalone imaging method, however, large-scale EM typically has two major limitations: slow rates of acquisition and the difficulty to provide targeted biological information. We developed a 3D...journal article 2022

Saeedifar, M. (author), Saghafi, Hamed (author), Mohammadi, Reza (author), Zarouchas, D. (author)The present study evaluates the toughening capability of electrospun PA66 nanofibers for carbon/epoxy composite laminates subjected to mode II loading conditions at elevated temperatures. The Dynamic Mechanical Analysis (DMA) test showed that the glass transition temperature of the produced nanofibers is in a range of ∼60–80 °C. Accordingly,...journal article 2021

Hari, S. (author), Trompenaars, P. H.F. (author), Mulders, J. J.L. (author), Kruit, P. (author), Hagen, C.W. (author)High resolution dense lines patterned by focused electron beam-induced deposition (FEBID) have been demonstrated to be promising for lithography. One of the challenges is the presence of interconnecting material, which is often carbonaceous, between the lines as a result of the Gaussian line profile. We demonstrate the use of focused electron...journal article 2021

Nierijnck, Sven (author)Hexavalent chromium has been the industry standard for corrosion protection for many years. Its unsurpassed active corrosion inhibiting capabilities, its incredible versatility and its economic benefits made it a popular all-rounder. Nowadays the widely known toxic and carcinogenic nature have restricted its use within the European Union. More...master thesis 2020

van Kessel, L.C.P.M. (author), Huisman, T.A. (author), Hagen, Cornelis W. (author)Background: 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. Aim: We study the response of a CD-SEM to sidewall roughness (SWR) by simulation. Approach: We generate...journal article 2020

van Kessel, L.C.P.M. (author), Hagen, C.W. (author), Kruit, P. (author)We have investigated the contributions of surface effects to Monte Carlo simulations of top-down scanning electron microscopy (SEM) images. The elastic and inelastic scattering mechanisms in typical simulations assume that the electron is deep in the bulk of the material. In this work, we correct the inelastic model for surface effects. We...conference paper 2019

Guatame-Garcia, Adriana (author), Buxton, M.W.N. (author)Diatomite, a rock formed by the accumulation of opaline diatom frustules, is a preferred raw material for the manufacturing of filters. Its uniqueness relies on the high porosity and inertness of the frustules. The presence of carbonates in some diatomite ores hinders these properties. The~purpose of this study was to identify the type of...journal article 2018
