Cathode Rays

This consisted of bringing a negative electrode close to the patient, usually near the spine, causing sparks to be produced between the electrode and the patient.

He observed tubes with energy rays extending from a negative electrode.

But I can't put in an electrode and say, Go there.

In an electrolysis experiment, there is a one to one correspondence between the electrons passing through the anode to cathode wire and the ions that plate onto or off of the anode or cathode.

He merely moistened the skin with vinegar before applying the zinc electrode.

In the blue wire, we see what's called a deep brain electrode.

He found that cathode rays were emitted perpendicularly from a metal surface, and carried energy.

Bird's design was based on a modification of an existing instrument for the local electrical treatment of hemiplegia, and consisted of a silver electrode and a zinc electrode connected by copper wire.

The glucose in the blood reacts with an enzyme electrode containing glucose oxidase (or dehydrogenase).

The silver electrode of the moxa was applied to the ulcer to be healed, while the zinc electrode was applied a few inches away to a place where the upper layer of skin had been cut away.

A stream of hydrogen is delivered to the anode side of the membrane electrode assembly (MEA).

You may or may not have noticed that I'm wearing a tiny electrode on my forehead.

Because these latter rays passed through the holes, or channels, in the cathode, Goldstein called them Kanalstrahlen , or canal rays.

The formation of copper plates on the cathode was noticed in the Daniell cell shortly after its invention in 1836.

He then showed that the luminescence rays appearing within the tube carried energy and moved from the cathode to the anode.

He discovered several important properties of cathode rays, which contributed to their later identification as the first subatomic particle, the electron.

And in the end, you achieve something like this where an electrode array is inserted inside the cochlea.

The other part of the virus has a sequence that can grow an electrode material for a battery.

And if you trigger, if you stimulate with an electrode, the precise spot, you will trigger an orgasm.

One of the first portable, chemistry based sensors was the glass pH electrode, invented in 1922 by Hughes (Hughes, 1922).

And this forces magnesium to de alloy and return to the upper electrode, restoring the initial constitution of the battery.

This electrode here, called the gate, controls the flow of current from the source to the drain these two electrodes.

In 1876, the German physicist Eugen Goldstein showed that the rays from this glow cast a shadow, and he dubbed the rays cathode rays.

He became an assistant at the school during the period of 1894 97 when he began the study of cathode rays and X rays.

The memory was in cathode ray tubes a whole bunch of spots on the face of the tube very, very sensitive to electromagnetic disturbances.

As in a conventional alkaline battery, an anode (the titanium dioxide) and a cathode (the platinum) are placed on either side of a liquid conductor (the electrolyte).

He also investigated the light spectra of gases and vapours, worked on the passage of electricity through gases, and discovered new properties of cathode rays (electron rays).

For sensory nerves, the opposite applied flow was from the extremity to the centre, and the positive electrode would be applied to the extremity.

You see the electrode going through the skull into the brain and resting there, and we can place this really anywhere in the brain.

I would pay a good price to see you wearing only one stocking and your tearedup dress to fix the electrode on your skin!

And Whewell not only coined the term scientist, as well as the words anode, cathode and ion, but spearheaded international big science with his global research on the tides.

Again, we are making holes in the skull about the size of a dime, putting an electrode in, and then this electrode is completely underneath the skin down to a pacemaker in the chest, and with a remote control very much like a television remote control, we can adjust how much electricity we deliver to these areas of the brain.

The idea of potential drop on the injection electrode was introduced by William Shockley to explain the difference between the experimental results and the model of gradual channel approximation.

For example, we can connect the recording electrode to a cursor on a screen and have the patient move the cursor left or right just by thinking of things.

For two electrode systems the specific contact resistivity is experimentally defined as the slope of the I V curve at V 0 formula_1where J is the current density current area.

Arc welding is a type of welding that uses a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point.

One was the electric bath, which consisted of sitting the patient on an insulated stool with glass legs and connecting the patient to one electrode, usually the positive one, of an electrostatic machine.

In 1896, the British physicist J. J. Thomson, with his colleagues John S. Townsend and H. A. Wilson, performed experiments indicating that cathode rays really were unique particles, rather than waves, atoms or molecules as was believed earlier.

The electrodes have to be placed on the calf either both electrodes on one calf if the venous disease affects only one leg, or one electrode on each calf if the pathology concerns both legs.

We know that if you stimulate the temporal lobe, you can produce a feeling of out of body experiences, near death experiences, which you can do by just touching an electrode to the temporal lobe there.

One part of the virus grabs a carbon nanotube, the other part of the virus has a sequence that can grow an electrode material for a battery, and then it wires itself to the current collector.

We know that if you stimulate the temporal lobe, you can produce a feeling of out of body experiences, near death experiences, which you can do by just touching an electrode to the temporal lobe there.

We want to develop these little tiny capsules about the size of a piece of risotto that we can put into the muscles and telemeter out the EMG signals, so that it's not worrying about electrode contact.
