The basic science of water is essential to many fields, including advanced water treatment technologies that rely on nanostructured materials such as nanoparticle-embedded filtration membranes. A fundamental understanding of the behavior of water molecules in the bulk, at surfaces, and in confined geometries is critical to enable continued progress in science and engineering that involve such water processes at the macroscale.

A new flexible magnetoelectric field-effect transistor concept based on magenetoelectric gate dielectric is proposed and used to detect a magnetic field and extract the magnetoelectric properties of thin magnetoelectric materials. With flexible properties, the device exhibits mechanical stability after cyclic bending and near-invariance of the electrical response under flexure.

Ultrahigh magnetic gradients at Fe3O4-nanoparticle-modified electrodes (>108 T﹞m-1) induce enhanced mass transport to the electrodes. This is attributed to the magnetic field gradient force and the superparamagnetic properties of nano-Fe3O4, which enable switching of the force using an external magnetic field.
