Amador, G.J. (author), van Dijk, Dennis (author), Kieffer, R.Y. (author), Aubin-Tam, M.E. (author), Tam, D.S.W. (author)Vital biological processes, such as trafficking, sensing, and motility, are facilitated by cellular lipid membranes, which interact mechanically with surrounding fluids. Such lipid membranes are only a few nanometers thick and composed of a liquid crystalline structure known as the lipid bilayer. Here, we introduce an active, noncontact, two...journal article 2021

Mastromarino, S. (author), Rook, R. (author), de Haas, D.W. (author), Verschuur, D.J. (author), Rohde, M. (author), Kloosterman, J.L. (author)A method based on ultrasonic wave propagation is applied for the determination of the viscosity of low viscous liquids. A waveguide is used to remotely transmit the ultrasonic waves from a shear piezoelectric transducer into the liquid. At the solid-liquid interface, a guided wave mode, the shear mode, is used to extract the liquid viscosity....journal article 2021

Mosleh, Yasmine (author), Mosleh, Y. (author), Beerkens, L.G.M. (author), Poulis, J.A. (author), de la Rie, E. René (author)Materials, both natural and synthetic, are used as adhesives or consolidants during the conservation of cultural objects. However, few adhesives have been formulated specifically for the needs of cultural heritage. This article describes a study of the stability of ethylene butyl acrylate copolymers as well as blends of these polymers with low...journal article 2021

(author), Boom, R. (author), Yang, Y. (author)The optimal hot metal desulphurisation (HMD) slag is defined as a slag with a sufficient sulphur removal capacity and a low apparent viscosity (η<sub>slag</sub>) which leads to low iron losses. In part I of this study, the fundamentals behind the optimal slag were discussed. In this part these fundamentals are explored by a Monte Carlo...journal article 2021

Kraaij, R.C. (author), Schlottke, Mikola C. (author)We study the well-posedness of Hamilton–Jacobi–Bellman equations on subsets of R<sup>d</sup> in a context without boundary conditions. The Hamiltonian is given as the supremum over two parts: an internal Hamiltonian depending on an external control variable and a cost functional penalizing the control. The key feature in this paper is that...journal article 2021

(author)In hot metal desulphurisation (HMD) the slag will hold the removed sulphur. However, the iron that is lost when the slag is skimmed off, accounts for the highest costs of the HMD process. These iron losses are lower when the slag has a lower viscosity, which can be achieved by changing the slag composition. A lower slag basicity decreases the...journal article 2021

Ren, S. (author), Liu, X. (author), Xu, Jian (author), Lin, P. (author)Porous asphalt pavement is widely used due to its adequate water permeability, noise reduction and skid resistance. The study aims at exploring the potential of using the crumb rubber/styrene–butadienestyrene (CR/SBS) modified bitumen as high-viscosity binder for porous asphalt mixture, and investigating the effect of swelling and degradation...journal article 2021
