Preferential Nucleation Sites Regulate Hydrogen Bubble Evolution on Mesh Electrodes

Gas-bubble evolution substantially affects the efficiency of gas-evolving electrochemical processes, including water electrolysis. Bubble nucleation, growth, coalescence, and detachment influence the electrode potential, while persistent bubble coverage can impede ionic...

Performance Estimation and Ex Vivo Validation of Untethered Magnetic Robots in Soft Tissue

ABSTRACT The navigation and control of untethered magnetic robots (UMRs) within soft brain tissue critically depend on their ability to maintain synchronized rotation under applied rotational magnetic fields. The fundamental upper limit of this magnetic synchronization, known as...
