- ItemMagnetic suspension array technology: Controlled synthesis and screening in microfluidic networks(Hoboken, NJ : Wiley, 2016) Lin, Gungun; Karnaushenko, Dmitriy D.; Cañón Bermúdez, Gilbert Santiago; Schmidt, Oliver G.; Makarov, DenysInformation tagging and processing are vital in information‐intensive applications, e.g., telecommunication and high‐throughput drug screening. Magnetic suspension array technology may offer intrinsic advantages to screening applications by enabling high distinguishability, the ease of code generation, and the feasibility of fast code readout, though the practical applicability of magnetic suspension array technology remains hampered by the lack of quality administration of encoded microcarriers. Here, a logic‐controlled microfluidic system enabling controlled synthesis of magnetic suspension arrays in multiphase flow networks is realized. The smart and compact system offers a practical solution for the quality administration and screening of encoded magnetic microcarriers and addresses the universal need of process control for synthesis in microfluidic networks, i.e., on‐demand creation of droplet templates for high information capacity. The demonstration of magnetic suspension array technology enabled by magnetic in‐flow cytometry opens the avenue toward point‐of‐care multiplexed bead‐based assays, clinical diagnostics, and drug discovery.
- ItemVirtual Testing of Geometrically Imperfect Additively Manufactured Lattice Structures(Hoboken, NJ : Wiley, 2021) Gebhardt, Ulrike; Kästner, Markus; Hufenbach, Julia Kristin; Kühn, Uta; Berner, Matthias; Holtzhausen, StefanAdditively manufactured lattice structures increase the lightweight potential of components for technical applications. When modelling the mechanical behaviour of those lattice structures, imperfections within the structures need to be considered. In this contribution we investigate the effect of process induced pores of varying size and location inside the lattice structure during pressure tests using a 2D minimal model in two configurations. It shows that the location of pores with respect to the configuration of the model has a strong influence on whether the imperfection decreases the mechanical performance.
