Membranes, 2022 The working principle of lateral flow assays, such as the widely used COVID-19 rapid tests, is based on the capillary-driven liquid transport of a sample fluid to a test line using porous polymeric membranes as the conductive medium.

Computation of Optimal Current References for Flux-weakening of Multi-Phase Synchronous Machines [PDF]
, 2012 Multi-phase synchronous machines are more and more used in specific applications where high power density, low bus voltage, wide speed range and fault-tolerant capabilities are required. Due to the high number of degrees of freedom, multi-phase machines

Composite fermion liquid to Wigner solid transition in the lowest Landau level of zinc oxide
Nature Communications, 2018 In two-dimensional electron systems, strong Coulomb interactions lead to the formation of new phases. Here the authors observe a transition between two of these correlated phases, a composite fermion liquid and Wigner solid, in a zinc oxide ...

The deviation from eutectic composition in boundary layer for eutectic growth: a phase-field study [PDF]
Archives of Metallurgy and Materials, 2019 In this paper, the deviation from eutectic composition in boundary layer for eutectic growth is studied by phase-field method. According to a series of artificial phase diagram, the lamellar eutectic growth of these alloy is simulated during directional ...

Phase Field Simulation of AA6XXX Aluminium Alloys Heat Treatment
Metals, 2021 Heat treatment has a significant impact on the microstructure and the mechanical properties of Al-Mg-Si alloys. The present study presents a first Phase-Field modelling approach on the recrystallisation and grain growth mechanism during annealing.

Phase Field Methods and Dislocationss
MRS Proceedings, 2000 We present a general formalism for incorporating dislocations in Phas Field methods. This formalism is based on the elastic equiva;ence betweem a dislocation loop and a platelet inclusion of specific stress-free strain related to the loop Burgers vector and normal.

Phase-Field Models with Hysteresis
Journal of Mathematical Analysis and Applications, 2000 Phase-field systems as mathematical models for phase transitions have drawn increasing attention in recent years. However, while capable of capturing many of the experimentally observed phenomena, they are only of restricted value in modelling hysteresis effects occurring during phase transition processes. To overcome this shortcoming of existing phase-

The effect of forest dislocations on the evolution of a phase-field model for plastic slip [PDF]
, 2019 We consider the gradient flow evolution of a phase-field model for crystal dislocations in a single slip system in the presence of forest dislocations.
