Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
A conductor through which electricity enters or leaves an object, substance, or region.
- ‘When electricity was applied to the electrodes, rays appeared to come from the cathode.’
- ‘The particles carry the electrons to one of the electrodes, generating a current.’
- ‘By depriving the bacteria of oxygen, electrons are freed to set up a voltage between the electrodes.’
- ‘They then receive an electrical ‘shock’ to the brain, through electrodes placed on the head.’
- ‘To increase the chance of securing a recording during an attack patients may be fitted with electrodes that transmit by radio to a receiver.’
- ‘The lower surfaces of the electrode segments define an electrode segment plane.’
- ‘Finally, an aluminium electrode was vacuum-deposited on top of the organic film.’
- ‘The electrode sends electrical signals backwards along the vagus nerve to the brain.’
- ‘Under a weak electric field, the holes drift toward a matrix of a million or so tiny pixel electrodes.’
- ‘The surgical procedure involves implanting electrodes in a region of the brain thought to drive depression.’
- ‘This device transmits sound directly into the auditory nerve via electrodes surgically implanted into the cochlea.’
- ‘Redistribution of ions within the electrode, causes a relatively slow change in the capacitance during voltage clamp.’
- ‘He connected the same pairs of electrodes and simulated the electrical connection.’
- ‘When air is brought into contact with the second electrode, current flows through any circuit linking the two electrodes.’
- ‘Oxidation of the dye molecule injects electrons into the semiconducting electrode.’
- ‘At this point the question arises as to what the alligator-shaped electrodes measure.’
- ‘The wider ends of the gate electrodes straddle the peripheral boundaries of the active region.’
- ‘Sound is converted to signals by the processor and transmitted to the auditory nerves by the electrodes.’
- ‘At the two ends of the conductor are the electrodes, which gather and disperse the electrons.’
- ‘Once the electrode box has been opened, the electrodes should be kept in a dry box until used.’
Mid 19th century: from electric + Greek hodos ‘way’, on the pattern of anode and cathode.
