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

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, 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

Schyck, S.N. (author)Colloidal particles, essential building blocks known since the 1800s, continue to captivate researchers. This thesis delves into their significance by investigating anisotropic particle design, shape-driven self-assembly, and enhancing magnetic colloids' role as active swimmers. It also introduces innovative methods for crafting anisotropic...doctoral thesis 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

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

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

Foppen, J.W.A. (author)The use of artificial DNA (artDNA) in hydrological applications is becoming increasingly popular, either in dissolved form (dissolved artDNA) or encapsulated and protected by a layer (encDNA). DNA can be detected even at low concentrations and offers the ability to create numerous uniquely identifiable DNA labels, making it ideal for a wide...review 2023

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

van de Velde, Jeroen (author)Janus particles are colloidal particles for which one half of the surface has different attributes than the other half. One property of a spherical dielectric particle with half of its surface covered by a layer of another dielectric or metal is that it has a non-uniform scattering pattern when exposed to light. However, the angle with which the...bachelor thesis 2022

Linne, C. (author)To bind two entities together, an attractive interaction is needed. In biological systems, such interactions are often between ligands and receptors. But this interaction constantly breaks and forms because it is (too) weak. To ensure a lasting bond, the system can form multiple weak bonds that form an overall strong bond – similar to velcro. An...doctoral thesis 2022

't Hoen, Jesse (author)Light-emitting electrochemical cells (LECs) form a cheap and easily produced alternative to (organic) light-emitting diodes ((O)LEDs) due to their simple device structure and the ability to form an in-situ pi- n junction. Usage of quantum dots (QDs) as a luminophore in LECs is expected to result in devices with improved emission properties and...master thesis 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

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

Spekreijse, Pierrick (author)Colloidal particle swarms can show settling velocities over a thousand times as fast as that of a single particle. The transport of colloidal particles is thus strongly affected by the formation and behaviour of these particle swarms, which could have important implications for the widespread use and prevalence of colloidal particles. Swarming...master thesis 2021

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
