Exempel på hur man kan använda TUNGSTEN i en mening

• student, Kanwar Bahadur (Pennsylvania State University) observed individual tungsten atoms on the surface of a sharply pointed tungsten tip by cooling it to 21 K and employing helium as the imaging gas.
• Mongolia also has extensive mineral deposits: copper, coal, molybdenum, tin, tungsten, and gold account for a large part of industrial production.
• Chemistry experiments have confirmed that seaborgium behaves as the heavier homologue to tungsten in group 6.
• The metal with the highest melting point is tungsten, at ; this property makes tungsten excellent for use as electrical filaments in incandescent lamps.
• A halogen lamp (also called tungsten halogen, quartz-halogen, and quartz iodine lamp) is an incandescent lamp consisting of a tungsten filament sealed in a compact transparent envelope that is filled with a mixture of an inert gas and a small amount of a halogen, such as iodine or bromine.
• Scheele discovered oxygen (although Joseph Priestley published his findings first), and identified molybdenum, tungsten, barium, nitrogen, and chlorine, among others.
• Before it was a national park the land was mined for molybdenite, arsenic, tungsten, copper, gold and tin.
• The town's first economic boom came when minerals such as tungsten, silver, and gold were discovered near Tungsten (east of Nederland), Caribou (northwest of Nederland, 1859), and Eldora (west of Nederland, 1875).
• Westminster is home to several industries; among them are: US Engine Valve plant, Ulbrich (flat wire manufacturing plant), and Sandvik Tooling Supply, a global supplier of tungsten carbide cutting tools.
• A semiconductor plug, typically tungsten, is used to fill a via and connect different wiring levels on wafers.
• Famous examples zinc sulfide, which contains zinc and sulfur, and tungsten carbide, which contains tungsten and carbon.
• The book is named after Sacks's Uncle Dave, whom Oliver nicknamed Uncle Tungsten because he was secretary of a business named Tungstalite, which made incandescent lightbulbs with a tungsten filament.
• Oruro has been subject to cycles of boom and bust owing to its dependence on the mining industry, notably tin, tungsten (wolfram), silver and copper.
• He pioneered the technologies for aluminum/titanium layered interconnects, which became an industry standard, as well as CVD of MOS gates with alternative materials such as tungsten, WSi2, and SiGe.
• A common material combination for the primary sealing surfaces is a hard material, such as silicon carbide, ceramic or tungsten carbide and a softer material, such as carbon.
• An X-ray tube is a simple vacuum tube that contains a cathode, which directs a stream of electrons into a vacuum, and an anode, which collects the electrons and is made of tungsten to evacuate the heat generated by the collision.
• Though cheaper, the acetate filters eventually fell out of favor with professional organizations since they could not withstand the higher temperatures produced by the tungsten halogen lamps that came into widespread use in the late 1960s.
• Mordants include tannic acid, oxalic acid, alum, chrome alum, sodium chloride, and certain salts of aluminium, chromium, copper, iron, iodine, potassium, sodium, tungsten, and tin.
• The rules permit the cars to be augmented with tungsten carbide weights up to the limit, and graphite axle lubricant.
• As this is investigated, Hallam gets the credit for suggesting that the matter has been exchanged by beings in a parallel universe; this leads to the development of a cheap, clean, and apparently endless source of energy: the "Pump", which transfers matter between our universe (where plutonium 186 decays into tungsten 186) and a parallel one governed by different physical laws (where tungsten 186 turns into plutonium 186), yielding a nuclear reaction in the process.
