(author), Zadpoor, A.A. (author)Additively manufacturing of porous iron offers a unique opportunity to increase its biodegradation rate by taking advantage of arbitrarily complex porous structures. Nevertheless, achieving the required biodegradation profile remains challenging due to the natural passivation of iron that decrease the biodegradation rate. Moreover, the...journal article 2022

Annaduzzaman, M. (author), Rietveld, L.C. (author), Hoque, Bilqis Amin (author), van Halem, D. (author)Sequential iron (as Fe<sup>2+</sup>) oxidation has been found to yield improved arsenic (as As(III)) uptake than the single-step oxidation. The objective of this study was to gain a better understanding of interactions with phosphate (PO<sub>4</sub><sup>3−</sup>) and silicate (SiO<sub>4</sub><sup>2−</sup>) during sequential Fe<sup>2+</sup>...journal article 2022

(author)Copper promotion of chromium-doped iron oxide prepared via co-precipitation for high-temperature water–gas shift (WGS) catalysis is investigated. Low-temperature Mössbauer spectra demonstrate that copper doping delays hematite (α-Fe<sub>2</sub>O<sub>3</sub>) formation in the fresh catalyst, favoring the formation of small crystallites of...journal article 2022

Bicudo, Bruno (author), Van Der Werff, Bart Jan (author), Medema, G.J. (author), van Halem, D. (author)Electrochemical water treatment is gaining increasing popularity due to its wide range of potential applications, its decreasing costs, and its suitability as a decentralized treatment alternative, but mainly due to it being considered a "green technology". In the field of municipal wastewater treatment, the use of iron electrocoagulation (Fe...journal article 2022

Hagen, W.R. (author)Analysis of citation networks in biomedical research has indicated that belief in a specific scientific claim can gain unfounded authority through citation bias (systematic ignoring of papers that contain content conflicting with a claim), amplification (citation to papers that don't contain primary data), and invention (citing content but...journal article 2022

(author), de Ram, C. (author), Pabst, Martin (author)Iron-sulfur (Fe-S) clusters are ancient and ubiquitous protein cofactors and play irreplaceable roles in many metabolic and regulatory processes. Fe-S clusters are built and distributed to Fe-S enzymes by dedicated protein networks. The core components of these networks are widely conserved and highly versatile. However, Fe-S proteins and...journal article 2022

Simon, B.G. (author), Kurdi, S. (author), Carmiggelt, J.J. (author), Borst, M. (author), Katan, A.J. (author), van der Sar, T. (author)Nitrogen-vacancy (NV) magnetometry is a new technique for imaging spin waves in magnetic materials. It detects spin waves by their microwave magnetic stray fields, which decay evanescently on the scale of the spin-wavelength. Here, we use nanoscale control of a single-NV sensor as a wavelength filter to characterize frequency-degenerate spin...journal article 2022

Roy, M. (author), van Genuchten, Case M. (author), Rietveld, L.C. (author), van Halem, D. (author)Groundwater contaminated with arsenic (As) must be treated prior to drinking, as human exposure to As at toxic levels can cause various diseases including cancer. Conventional aeration-filtration applied to anaerobic arsenite (As(III)) contaminated groundwater can remove As(III) by co-oxidizing native iron (Fe(II)) and As(III) with oxygen (O...journal article 2022

de Kwant, Jochem de Kwant (author)In order to meet climate change mitigation targets, the shipping industry must change to an alternative fuel. From a ship design perspective, the switch to an alternative fuel is often a downgrade with respect to the use of conventional fuels. For instance, most alternative fuels have a low energy density, rely on technology that is not fully...master thesis 2021

Willeijns, Jelle (author)As liquid bulk vessels are berthed in ports, auxiliary engines generate the electrical power demand, which emissions have a negative effect on the environment and local air quality in ports. Shore power is an effective solution for this problem. However, the large costs of implementing shore power and the absence of a technical safe design...master thesis 2021

Goedhart, Roos (author)The removal of iron from groundwater is essential to avoid aesthetic issues of the produced drinking water and to reduce maintenance cost of the system. The most applied iron removal method of oxidation and filtration produces large volumes of aqueous iron sludge of little value and the method is more likely to fail at high iron concentrations....master thesis 2021

(author)The presence of soluble iron and phosphorus in wastewater sludge can lead to vivianite scaling. This problem is not often reported in literature, most likely due to the difficult identification and quantification of this mineral. It is usually present as a hard and blue deposit that can also be brown or black depending on its composition and...journal article 2021

Ebrahimi, Nafiseh (author), Ghaziaskar, Amin (author), Makar, Jon M. (author)It is well known that iron sulphides such as pyrite (FeS2) and pyrrhotite ((Fe1-xS, 0-x-0.125) are unstable in presence of oxygen and moisture, oxidizing to produce sulfuric acid and iron sulphate. Further reactions in concrete cause the formation of expansive reaction products such as ettringite and thaumasite, potentially leading to structural...conference paper 2021
