nernst lamp การใช้

• Eventually, Nernst Lamp Company ceased operations as newer technologies surpassed the lamp.
• Dunham also launched the Nernst lamp into commercial use.
• During her time there, she became the first person to use a Nernst lamp for a physics project.
• Twice as efficient as carbon filament lamps, Nernst lamps were briefly popular until overtaken by lamps using metal filaments.
• The mineral species rich in yttrium-erbium were more particularly sought after because thorium and uranium were not used in the " glower " of the Nernst lamp.
• His work was continued by Walther Nernst, who derived the Nernst equation and described ionic conduction in heterovalently doped zirconia, which he used in his Nernst lamp.
• Fundamental contributions were later made by Walther Nernst, who derived the Nernst equation and detected ionic conduction in heterovalently doped zirconia, which he applied in his Nernst lamp.
• Contrary to the existing carbon-filament lamps, Nernst lamp could operate in air and was twice more efficient as its emission spectrum was closer to that of daylight.
• The Nernst Lamp Company, a subsidy of Westinghouse, then bought Barringer Hill and began mining, extracting a few hundred pounds of ytrria minerals annually for a few years.
• In 1897, German physicist and chemist Walther Nernst developed the Nernst lamp, a form of incandescent lamp that used a ceramic globar and did not require enclosure in a vacuum or inert gas.
• AEG, a lighting company in Berlin, bought the Nernst s patent for one million German gold marks, which was a fortune at the time, and used 800 of Nernst lamps to illuminate their both at the world s fair Exposition Universelle ( 1900 ).
• In addition to their usage for ordinary electric illumination, Nernst lamps were used in one of the first practical long-distance photoelectric facsimile ( fax ) systems, designed by professor Arthur Korn in 1902, in Allvar Gullstrand's slit lamp ( 1911 ) for ophthalmology, for projection and in microscopy.
• After Nernst lamps fell into obsolescence " Nernst glowers " went on to be used as the infrared-emitting source used in IR spectroscopy devices . ( Recently, even this has become obsolete as Nernst glowers have been largely replaced for this purpose by silicon carbide glow bars or " globars ", which are conductive even at room temperature and therefore need no preheating .)
