Zhang, S. (author), Liang, Yaxin (author), Yang, Cai (author), Venema, Paul (author), Rietveld, L.C. (author), Heijman, Sebastiaan (author)A large decrease in permeability is often observed during the filtration of nano-sized colloids, while fouling is widely regarded as the main explanation for this phenomenon. The osmotic pressure or concentration polarization (CP) of colloids can also contribute to the flux decline. However, the contribution of CP to flux loss cannot be...journal article 2024

Egelhaaf, Stefan U. (author), Mao, Xiaoming (author), Dijkstra, Marjolijn (author), Pine, David J (author), Kumar, Sanat K. (author), Aubin-Tam, M.E. (author), Koenderink, G.H. (author)Soft materials are usually defined as materials made of mesoscopic entities, often self-organised, sensitive to thermal fluctuations and to weak perturbations. Archetypal examples are colloids, polymers, amphiphiles, liquid crystals, foams. The importance of soft materials in everyday commodity products, as well as in technological applications,...journal article 2024

Zhang, M. (author), Raghunath, Aparna (author), Zhao, A. (author), Eral, H.B. (author)On-dose authentication (ODA) enhances security by incorporating customized molecular or micro-tags into each pill, preventing counterfeit products in genuine packages. ODA's security relies on tag non-replication and non-reverse engineering. Combining ODA with graphical Physical Unclonable Functions (PUF) promises maximum security. PUF uses...journal article 2024

Spiekhout, Sander (author), van Elburg, Benjamin (author), Voorneveld, J.D. (author), de Jong, N. (author), Versluis, Michel (author), Bosch, Johannes G. (author), Segers, Tim (author)Phospholipid-coated microbubbles with a uniform acoustic response are a promising avenue for functional ultrasound sensing. A uniform acoustic response requires both a monodisperse size distribution and uniform viscoelastic shell properties. Monodisperse microbubbles can be produced in a microfluidic flow focusing device. Here, we investigate...journal article 2024

Chakraborty, S. (author), Elhaj, Rayan (author), Foppen, J.W.A. (author), Schijven, Jack (author)We investigated the applicability of Silica encapsulated, superparamagnetic DNA particles (SiDNAmag) in determining aquifer hydraulic parameters at different ionic strengths (1 mM, 5 mM, and 20 mM phosphate buffer) of injection suspension. Thereto, in a homogeneous, unconsolidated sand tank we pulse - injected two uniquely sequenced SiDNAmag...journal article 2023

Kianfar, B. (author), Hassanizadeh, S. Majid (author), Abdelrady, Ahmed (author), Bogaard, T.A. (author), Foppen, J.W.A. (author)In the terrestrial environment, interactions between natural organic matter (NOM) and colloids can lead to the formation of an environmental corona around colloids, influencing their transport behaviour and, ultimately, their ecotoxicity. We used a synthetically designed colloid tagged with DNA (DNAcol) as a surrogate for natural colloids and...journal article 2023

Schyck, S.N. (author), Meijer, Janne Mieke (author), Schelling, Max P. (author), Petukhov, Andrei V. (author), Rossi, L. (author)The self-assembly of materials driven by the inherent directionality of the constituent particles is of both practical and fundamental interest because it enables the fabrication of complex and hierarchical structures with tailored functionalities. By employing evaporation assisted self-assembly, we form opal-like structures with micro-sized...journal article 2023

Assaf Martinez-Streignard, E.I. (author), Liu, X. (author), Lin, P. (author), Erkens, S. (author), Nahar, Sayeda (author), Mensink, Liz I.S. (author)Conventional Molecular Dynamics (MD) models of bitumen are built by homogeneously mixing molecules in a volume without considering that the molecules in bitumen are known to exhibit phase behavior and form distinctive molecular arrangements. These are known to have a significant impact in the behavior of bitumen, and considering their...journal article 2023

Saha, S. (author), Luckham, Paul F. (author), Garbin, V. (author)Hypothesis: High-frequency interfacial rheology of complex interfaces remains challenging yet it is central to the performance of multiphase soft matter products. We propose to use ultrasound-driven bubble dynamics to probe the high-frequency rheology of a colloid monolayer used as model system with controlled interactions and simultaneous...journal article 2023

Kianfar, B. (author), Tian, Jingya (author), Rozemeijer, Joachim (author), van der Zaan, Bas (author), Bogaard, T.A. (author), Foppen, J.W.A. (author)In recent years, DNA-tagged silica colloids have been used as an environmental tracer. A major advantage of this technique is that the DNA-coding provides an unlimited number of unique tracers without a background concentration. However, little is known about the effects of physio-chemical subsurface properties on the transport behavior of...journal article 2022

Schyck, S.N. (author), Meijer, Janne Mieke (author), Baldauf, L. (author), Schall, Peter (author), Petukhov, Andrei V. (author), Rossi, L. (author)Understanding the relationship between colloidal building block shape and self-assembled material structure is important for the development of novel materials by self-assembly. In this regard, colloidal superballs are unique building blocks because their shape can smoothly transition between spherical and cubic. Assembly of colloidal...journal article 2022

Xu, Yanghui (author), Ou, Q. (author), Li, Xiaoming (author), Wang, Xintu (author), van der Hoek, J.P. (author), Liu, Gang (author)The transport and fate of nanoplastics (NPs) in aquatic environments are closely associated with their colloidal stability, which is affected by aging and natural organic matter (NOM) adsorption. This study systematically investigated the combined effects of photoaging and NOM (e.g. humic acids, HA; and a model protein, bovine serum albumin, BSA...journal article 2022

Bouwman, W.G. (author)Spin-echo small-angle neutron scattering (SESANS) yields structural information on length scales from 30 nanometres up till 20 micrometres. These length scales match nicely those of colloids, protein networks and fat droplets, which are present in many food materials. This makes SESANS an excellent probe to study food materials. An interesting...journal article 2021

(author)Reliably distinguishing between cells based on minute differences in receptor density is crucial for cell-cell or virus-cell recognition, the initiation of signal transduction, and selective targeting in directed drug delivery. Such sharp differentiation between different surfaces based on their receptor density can only be achieved by...journal article 2021

Donaldson, J.G. (author), Schall, Peter (author), Rossi, L. (author)Manipulating the way in which colloidal particles self-organize is a central challenge in the design of functional soft materials. Meeting this challenge requires the use of building blocks that interact with one another in a highly specific manner. Their fabrication, however, is limited by the complexity of the available synthesis procedures...journal article 2021

Kooijman, G. (author), de Kreuk, M.K. (author), Houtman, C. (author), van Lier, J.B. (author)Literature frequently reports that colloids in aqueous matrices sorb a large fraction of pharmaceuticals. Since coagulation/flocculation removes colloids, it is expected that coagulation/flocculation in principle should be useful in concentrating pharmaceuticals in wastewater treatment, which would facilitate the treatment of these refractory...journal article 2020

(author), Houtepen, A.J. (author)In transient absorption (TA) measurements on Cd-chalcogenide quantum dots (QDs), the presence of a band-edge (BE) bleach signal is commonly attributed entirely to conduction-band electrons in the 1S(e) state, neglecting contributions from BE holes. While this has been the accepted view for more than 20 years, and has often been used to...journal article 2019
