Belloni, C. (author), Korving, L. (author), Witkamp, G.J. (author), Brück, E.H. (author), Dugulan, A.I. (author)Iron oxide-based adsorbents showed potential to reach ultra-low phosphorus (P) concentrations to prevent eutrophication and recover P. High affinity, high capacity at low P concentrations (<1 mg L<sup>−1</sup>), good stability, and reusability of the adsorbent are key factors for economic viability. In this study, nanoparticles of goethite...journal article 2024

Dicke, Linge (author)Background:<br/>Cancer is one of the leading causes of death worldwide. Targeted radionuclide therapy has become a important treatment, this is when a carrier molecule is attached to a radionuclide to deliver cytotoxic radiation levels to diseased cells. β<br/>− emitters are frequently used in RNT because they have a long penetration depth, such...bachelor thesis 2023

Belloni, C. (author), Korving, L. (author), Witkamp, G.J. (author), Brück, E.H. (author), Dugulan, A.I. (author)Phosphorus (P) removal from freshwater bodies to ultra-low concentrations is fundamental to prevent eutrophication, while its recovery is necessary to close the P usage cycle. Iron oxide-based adsorbents seem promising candidates, being abundant, cheap, and easy to synthesize compounds, with good affinity for P. Affinity is the key parameter...journal article 2023

(author)Hybrid anion exchange adsorbents (HAIX) seem promising to prevent eutrophication and recover phosphate (P). HAIX consist of an anion exchange resin (AIX) backbone, promoting anion physisorption (outer-sphere complex), impregnated with iron (hydr)oxide nanoparticles (NPs), for selective P chemisorption (inner-sphere complex). In this work, for...journal article 2023

van Krimpen, Eline (author)Treatment of early stage breast cancer is generally invasive to a patient's daily life while being treated. Therefore, to diminish the physical and psychological impact during and after recovery, a newly proposed minimally invasive therapy for early-stage breast cancer treatment is proposed. Within this study, this proposed treatment is modelled...master thesis 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

(author)Abstract: To monitor and manage hydrological systems such as brooks, streams, rivers, the use of tracers is a well-established process. Limited number of potential tracers such as salts, isotopes and dyes, make study of hydrological processes a challenge. Traditional tracers find limited use due to lack of multiplexed, multipoint tracing and...journal article 2021
