Innovation: Silicon-Based LED Chips 2011-05-31T04:00:00Z However, for complex technical reasons, no one has ever managed to get close to this theoretical minimum with a standard lens made of gallium phosphide. Scattering Microscope Peers Into the Nanoscale 2011-04-29T18:37:18Z The process is reminiscent of sharpening a pencil, albeit with a supercharged stream of gallium ions. Cracking a Tooth 2011-01-13T17:53:00Z Manganese-doped gallium arsenide is a prototypical magnetic semiconductor, which is why Gupta and Lee are now exploring how they might control the magnetic interaction between two or more manganese atoms using their discovery. Technique Turns Computer Chip Defects Into an Advantage 2010-12-10T16:23:00Z This precipitate is converted into gallium sulphate and finally into a pure specimen of the oxide, from which the metal is obtained by the electrolysis of an alkaline solution. Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 4 "G" to "Gaskell, Elizabeth" 2011-08-24T02:00:20.690Z Ribbons of steel a metre wide and half a hair’s width thick spool through vacuum chambers in which they are sputtered with copper, indium, gallium and selenium—collectively known as CIGS. The renewable-energy business: Shining a light 2010-12-09T10:31:00Z Light travels much more slowly in gallium phosphide than in air. Scattering Microscope Peers Into the Nanoscale 2011-04-29T18:37:18Z The material is a semiconductor called gallium manganese arsenide. Semiconductor Could Turn Heat Into Computing Power 2010-09-29T14:32:00Z Among ETFs soon to be released are funds designed to track small-cap companies in Thailand, producers of rare metals such as gallium and selenium, and shares of fishing-related companies. New ETF Charges Up a Niche 2010-07-18T21:48:00Z In neutral solutions, zinc gives a precipitate of gallium oxide. Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 4 "G" to "Gaskell, Elizabeth" 2011-08-24T02:00:20.690Z Of 41 minerals and metals it analyzed, the commission identified these 14 as short in supply: antimony, beryllium, cobalt, fluorspar, gallium, indium, germanium, graphite, magnesium, niobium, platinum group metals, rare earths, tantalum and tungsten. Europe Sounds Alarm on Minerals Shortage 2010-06-16T19:03:00Z The scientists made the antennas by injecting an alloy made of the metals gallium and indium, which remains in liquid form at room temperature, into very small hollow channels the width of a human hair. Antennas That Bend, Stretch and Twist 2010-03-19T18:05:00Z While gallium arsenide is a semiconductor used in cell phones today, the addition of the element manganese endows the material with magnetic properties. Semiconductor Could Turn Heat Into Computing Power 2010-09-29T14:32:00Z The elements gallium and indium were discovered in blende. Encyclopaedia Britannica, 11th Edition, Volume 4, Slice 1 "Bisharin" to "Bohea" The gallium mine was merely an attempt to cover himself with respectability. Forget Me Nearly Afghanistan, antimony, beryllium, , , cobalt, Democratic Republic of Congo, fluorspar, gallium, germanium, graphite, indium, magnesium, metals, minerals, niobium, platinum group metals, rare earths, Russia, tantalum, tungsten U.N. Europe Sounds Alarm on Minerals Shortage 2010-06-16T19:03:00Z Rubidium, caesium, thallium, indium and gallium were first discovered by means of this instrument; the study of the rare earths is greatly facilitated, and the composition of the heavenly bodies alone determinable by it. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 1 "Châtelet" to "Chicago" But we can count DuQuesne out, anyway, because he called me up this afternoon about some notes on gallium; so he is still in the Bureau. The Skylark of Space Three of them, scandium, germanium, and gallium, were found within fifteen years, and their properties agreed in a remarkable way with the predictions of Mendeléeff. An Elementary Study of Chemistry The gun you brought in was sold six months ago to Dorn Starret, resident of Ceres and proprietor of a small gallium mine there. Forget Me Nearly Sixteen years later all three of these predicted elements had been discovered, one by a Frenchman, one by a German and one by a Scandinavian, and named from patriotic impulse, gallium, germanium and scandium. Creative Chemistry Descriptive of Recent Achievements in the Chemical Industries In gallium the funnel disappears on the proto level, setting free its two contained segments, each of which forms a cylinder, thus yielding twelve bodies on the proto level. Occult Chemistry Clairvoyant Observations on the Chemical Elements In appearance it resembles zinc, being white or lead gray, soft, malleable and easily fusible, but in its chemical relation it resembles aluminium or gallium. The Gutenberg Webster's Unabridged Dictionary Section I, J, K, and L Give the derivation of the names of the following elements: thorium, gallium, selenium, uranium. An Elementary Study of Chemistry The mine might or might not be of consequence; gallium was used in a number of industrial processes, but beyond that was not particularly valuable. Forget Me Nearly Who, for instance, will find a use for gallium, the metal of France? Creative Chemistry Descriptive of Recent Achievements in the Chemical Industries B is the same as the right-hand funnel of gallium, except that its lowest body consists of two square-based pyramids and a tetrahedron. Occult Chemistry Clairvoyant Observations on the Chemical Elements Out of the twenty odd elements which had been rarer and more valuable than gold, such as uranium, gallium, etc., not one was found to answer the purpose. The Moon Metal A is exactly the same as the left-hand funnel of gallium, save for the substitution of a globe containing the familiar "cigar" and two square-based pyramids. Occult Chemistry Clairvoyant Observations on the Chemical Elements Antimony follows closely in the track of gallium and indium, the upper ring of spheres being identical.
