Magnetically Actuated Drops‐on‐Stilts Microrobots for Transport and Delivery of Hydrophobic Cargo

Advanced Materials Interfaces, EarlyView.
Iron oxide nanoparticles and oil droplets in external magnetic fields form “drops‐on‐stilts” microrobots that transport hydrophobic cargo. Tunable nanoparticle–droplet interactions generate stilt‐like structures. Field rotation enables walking, obstacle navigation, and collective motion.

An equivalent-effect phenomenon in eddy current non-destructive testing of thin structures

, 2019
The inductance/impedance due to thin metallic structures in non-destructive testing (NDT) is difficult to evaluate. In particular, in Finite Element Method (FEM) eddy current simulation, an extremely fine mesh is required to accurately simulate skin ...

Tube Testing with Eddy Current

Metalurgija, 2008
In papers are shown the results of tube testing with eddy current testing method. The dependence of the defect type from the shape of given signal is being analyzed. To determinate the exact location of defects the magnetic particle testing method is used. All located defects were analyzed by metallogrphic examination.
