(author)Cell shape and motility are determined by the cytoskeleton, an interpenetrating network of actin filaments, microtubules, and intermediate filaments. The biophysical properties of each filament type individually have been studied extensively by cell-free reconstitution. By contrast, the interactions between the three cytoskeletal networks are...journal article 2024

LI, BOWEN (author)This master's thesis addresses a critical gap in the field of road construction by focusing on the limitations of Styrene-Butadiene-Styrene modified bitumen (SBS-MB), a widely-used binder. While SBS-MB offers superior performance, its long-term efficacy is compromised due to various aging processes. Existing rejuvenators are insufficient for...master thesis 2023

Ji, Ning (author)Emulsions, characterized as a metastable dispersion of one liquid into a second one in the presence of surface-active agents, have complex rheology that interests both physicists and industries. Depending on the volume fraction of the dispersed phase ($\phi$), emulsions can display both solid-like and liquid-like behavior. Rheometrical...master thesis 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

Li, Hongyan (author), Li, Z. (author), Qiu, Liangsheng (author), Dong, Sufen (author), Ouyang, Jian (author), Dong, Xufeng (author), Han, Baoguo (author)This study aims to understand the effects and mechanisms of length, diameter, and functional group of carbon nanotubes (CNTs) on rheological behaviors of cementitious composites. The experimental results show that the addition of CNTs decreases the flow index and increases the critical shear rate of cementitious composites. CNTs with a sub...journal article 2023

Sun, Beibei (author), Sun, Yubo (author), Ye, G. (author), De Schutter, Geert (author)Although the application of blast furnace slag and fly ash-based alkali-activated concrete (BFS/FA-AAC) has both economic and environmental benefits, it is limited by the lack of a straightforward mix design method. In this paper, an experiment was conducted to investigate the effect of control factors, including the Na<sub>2</sub>O/binder...journal article 2023

Chen, Y. (author), Rahmani, Hossein (author), Schlangen, E. (author), Copuroglu, Oguzhan (author)The implementation of extrusion-based 3D concrete printing (3DCP) in large-scale constructions is currently limited by concerns regarding rheology control and the sustainability of this process. To address these issues, this study presents an approach to develop limestone-calcined clay-based cementitious (LC3) materials accelerated by Ca(NO...journal article 2023

Martinez Torres, C.E. (author), Grimbergen, Jos (author), Koopman, Jaap (author), Koenderink, G.H. (author)Background: Fibrinogen is a plasma protein forming the fibrin scaffold of blood clots. Its mechanical properties therefore affect the risk of bleeding as well as thrombosis. There has been much recent interest in the biophysical mechanisms controlling fibrin mechanics; however, the role of molecular heterogeneity of the circulating fibrinogen...journal article 2023
