In Situ Magnetic Ordering and Microfabrication of Liquid Crystal Networks with Discretized Alignment
Advanced Functional Materials, EarlyView.Miniaturizing liquid crystal network actuators typically demands costly laser writing or digital light processing. A low‐cost photolithography platform couples rotating photomasks with a Halbach magnetic array to discretize in‐plane molecular alignment down to 50 µm, producing programmable, light‐responsive grippers, checkerboards, and origami‐inspired

Magnetic Viscosity Effect on Grounded-Wire TEM Responses and Its Physical Mechanism
IEEE Access, 2020 Magnetic viscosity (MV) effect is a disturbance to the transient electromagnetic method (TEM). This effect will cause slow decay at the intermediate-late time of the TEM responses, leading to erroneous interpretation.
