unusual facts about cathode



Bunsen cell

The cell is named after its inventor, German chemist Robert Wilhelm Bunsen, who improved upon the Grove cell by replacing Grove's platinum cathode with carbon in the form of pulverized coal and coke.

Crookes tube

Eugen Goldstein thought he had figured out a method of measuring the speed of cathode rays.

It was used by Crookes, Johann Hittorf, Julius Plücker, Eugen Goldstein, Heinrich Hertz, Philipp Lenard and others to discover the properties of cathode rays, culminating in J.J. Thomson's 1897 identification of cathode rays as negatively charged particles, which were later named electrons.

Direct methanol fuel cell

Protons (H+) are transported across the proton exchange membrane - often made from Nafion - to the cathode where they react with oxygen to produce water.

Direct-ethanol fuel cell

Protons (H+) are transported across the proton exchange membrane to the cathode where they react with oxygen to produce water.

Electrode boiler

The electrodes are connected to a high voltage A.C. source (typically 6,600 volts to 13,800 volts){If D.C. voltage is used Electrolysis of water occurs decomposing water into its elements H2 at the cathode(-ve electrode) and O2 at the anode(+ve electrode)}.

Electrometer

The Bohnenberger electrometer, developed by J.G.F. von Bohnenberger, consists of a single gold leaf suspended vertically between the anode and cathode of a dry pile.

Ethel Léontine Gabain

Ethel received two commissions from Ferranti Hollinwood – Working on the Cathode Ray Tubes and A Giro Compass; one from Richard Haworth & Co.

Finnish parliamentary election, 1979

Holkeri declined to form a government, but Sorsa refused to continue as Prime Minister, due to the unpopularity that he had suffered amid the recession's lingering effects, his role in the establishment of the soon-to-be-bankrupt television cathode-ray tube factory Valco, his alleged belittling of family violence in a television interview, and his health problems (back pain).

Hindustan Copper

Capacity - 31,000 tpa copper cathode(the smelter and acid plant at KCC are under shutdown since late 2008 due to the slump in global commodity prices witnessed in 2008 and old machinery.Currently, only refinery for production of copper concentrate is working in addition to associated mines.)

John B. Goodenough

His group has identified LixFePO4 as a less costly cathode material that is safe for power applications such as machine tools and Hybrid electric vehicles.

Nanomaterial-based catalyst

Carbon nanotube supported catalysts can be used as a cathode catalytic support for fuel cells and metal nanoparticles have been used to catalyze the growth of carbon nanotubes.

Research Laboratory of Electronics at MIT

Under the leadership of Director Julius A. Stratton and Associate Director Albert G. Hill, it continued investigation on problems in physical electronics that involved cathodes, electronic emission, and gaseous conduction.

Vladimir K. Zworykin

At this time, however, he was also experimenting with an improved cathode ray receiving tube, filing a patent application for this in November 1929, and introducing the new receiver that he named "Kinescope", reading a paper two days later at a convention of the Institute of Radio Engineers.

Wedge base

Philips-branded sets and most store brands use an offset, with the longer anode (positive lead) being lower and the shorter cathode (negative lead) being higher on the wedge base.

William Eccles

Eccles invented the term Diode to describe an evacuated glass tube containing two electrodes; an anode and a cathode.

Zinc–air battery

Cobalt oxide/carbon nanotube hybrid oxygen reduction catalyst and Nickel-iron layered double hydroxide oxygen evolution cathode catalysts exhibited higher catalytic activity and durability in concentrated alkaline electrolytes than precious metal Platinum and Iridium catalysts.
