End Magnet Optimisation for the Reduction of the Thrust Ripple of Linear Switched-Flux Machines
2020 International Conference on Electrical Machines (ICEM), 2020 Thanks to the usage and the placement of permanent magnets, linear switched flux machines exhibit a good performance even at a moderate cost. However, these machines are affected by high detent force and on load thrust force ripples. The placement of additional magnets in the ends of the machine is one of the possible solutions to deal with the thrust ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...
