Solid-state nanofluidic devices have proven to be ideal systems to elucidate the physics of nanoscale ion transport. When the device confinement approaches the Debye length of ions in the fluid, new phenomena occur such as surface-charge-dominated transport and ion-selectivity. Although these effects have been understood for simple monovalent systems, application-critical divalent systems have ...

‘In some of my tests I have noticed the effects and deflection of these waves by metallic objects miles away. It seems to me that it should be possible to design apparatus by means of which a ship could radiate or project a divergent beam of these rays in any desired direction, which rays, if coming across a metallic object, such as another steamer or ship, would be reflected back to a receiver...
