Quasi-One-Dimensional van der Waals Lattices with Diverse Magnetism: New Platforms Towards Ultrathin Magnetic Nanowires
… This allows for the study of unique 1D magnetic fluctuations coupled with 1D characteristic transport behaviors. On the other hand, the vdW gaps open up possibilities to exfoliate these 1D vdW magnets for magnetic nanowire production. These nanowires would then be used to investigate 1D …

Directed transport of superparamagnetic microbeads using periodic magnetically textured substrates
Superparamagnetic microbeads (SPBs) have been widely used to capture and manipulate biological entities in a fluid environment. Chip-based magnetic actuation provides a means to transport SPBs in lab-on-a-chip technologies. This is usually accomplished using the stray magnetic field from patterned …
