Mechanical Analysis of the Quadruple Butterfly Coil during Transcranial Magnetic Stimulation and Magnetic Resonance Imaging.

Transcranial Magnetic Stimulation (TMS) is a tool for the treatment of psychiatric and neurological disorders. It involves using a transient magnetic field generated from electromagnetic coils in inducing an electric field (E-field) within the neurons of the brain. The induced E-field results in an increase in the brain membrane's electric potential, leading to polarization or depolarization of the neurons depending on the mode of treatment.

Chameleon Metals: Autonomous Nano-Texturing and Composition Inversion on Liquid Metals Surfaces.

Studies on passivating oxides on liquid metals are challenging, in part, due to plasticity, entropic, and technological limitations. In alloys, compositional complexity in the passivating oxide(s) and underlying metal interface exacerbates these challenges. This nanoscale complexity, however, offers an opportunity to engineer the surface of the liquid metal under felicitous choice of processing conditions.
