(author), Xie, Jingxiu (author)CO<sub>2</sub> hydrogenation to chemicals and fuels has the potential to alleviate CO<sub>2</sub> emissions and displace fossil resources simultaneously via consecutive RWGS and FTS reactions, also known as CO<sub>2</sub>-FTS. As Fe-based catalysts are active and selective for both reactions, their bifunctionality requires a delicate balance...journal article 2024

Deng, Z. (author), He, Qing (author), Manning, Andrew J. (author), Chassagne, C. (author)The interactions between organic and inorganic particles in the context of flocculation is an on-going topic of research. Most current researches do not distinguish between the effects of EPS (produced by microorganisms) and living microorganisms (like algae). In this study, the effect of salinity, EPS and living algae on sediment...journal article 2023

Shi, Can (author), Fan, Zheng (author), Connolly, David P. (author), Jing, Guoqing (author), Markine, V.L. (author), Guo, Y. (author)Railway ballast performance is dictated by a complex mix of mechanical properties. These effect its performance at the particle level for example in terms of particle degradation, but also at the track system level in terms of settlement and stability. Therefore this paper seeks to develop new understandings of ballast behaviour and identify...review 2023

Yan, Y. (author), Helmons, R.L.J. (author), Carr, Michael (author), Wheeler, Craig (author), Schott, D.L. (author)A convex pattern surface has been proposed and optimized to reduce sliding wear of bulk handling equipment by adjusting the flow behaviour of bulk material. This study aims at modelling the surface deformation of the convex pattern sample to investigate how effectively the sample reduces sliding wear. Archard wear model and a deformable...journal article 2023

Yan, Y. (author), Helmons, R.L.J. (author), Schott, D.L. (author)Sliding wear of bulk handling equipment (e.g., shovel bucket, mill and transfer chute) can be dramatically reduced by using a convex pattern surface compared to a flat surface, by adjusting the flow behavior of particles moving along the convex pattern surface. To study the effect of particle size relative to the dimensions of the convex pattern...journal article 2022

de Bruijn, Douwe S. (author), ten Eikelder, Henricus R.A. (author), Papadimitriou, V. (author), Olthuis, Wouter (author), van den Berg, Albert (author)The assessment of particle and cell size in electrical microfluidic flow cytometers has become common practice. Nevertheless, in flow cytometers with coplanar electrodes accurate determination of particle size is difficult, owing to the inhomogeneous electric field. Pre-defined signal templates and compensation methods have been introduced to...journal article 2022

Shakeel, A. (author), Kirichek, Alex (author), Chassagne, C. (author)Kaolinite suspensions are known to have quite fast settling behaviour and Newtonian character, particularly at low concentrations, due to the non-swelling nature of their constitutive particles. On the other hand, bentonite is known for its swelling and interacting nature, which leads to the formation of a network structure, even at low...journal article 2021

Deng, Z. (author), He, Qing (author), Chassagne, C. (author), Wang, Zhengbing (author)The variation of the floc population in the Changjiang Estuary has been studied for both winter and summer season as a function of the presence of living (micro)algae. The influence of algae has been characterized through the use of the chlorophyll-a concentration to suspended sediment concentration (CC/SSC) ratio. Two whole tidal cycle...journal article 2021

Gardella, Giorgio (author)Dissolved air flotation (DAF) is a water treatment technology meant for the separation of suspended particles from the water. Since the fifties of the XIX century, it has gained an important role in many sectors of water treatment applications. In general, the flux variability, the small space requirement, and the limited energy consumption...student report 2020

(author)The Differential Mobility Analyzer (DMA) is currently the most effective instrument for sizing sub-micrometer aerosol particles. An important requirement to ensure good performance in terms of sizing accuracy and resolution is that the flow field remains laminar and undisturbed along its classification zone. To achieve that, a flow straightener ...journal article 2020

Suresh Kumar, P. (author), Korving, Leon (author), Keesman, Karel J. (author), van Loosdrecht, Mark C.M. (author), Witkamp, G.J. (author)Phosphate is a vital nutrient but its presence in surface waters even at very low concentrations can lead to eutrophication. Adsorption is often suggested as a step for reducing phosphate down to very low concentrations. Porous metal oxides can be used as granular adsorbents that have a high surface area and hence a high adsorption capacity....journal article 2019
