Lawv coercivity qis kuj ua rau poob qis. Lub superconductivity ntawm amorphous hlau nyias zaj duab xis tau pom nyob rau hauv thaum ntxov 1950s los ntawm Buckel thiab Hilsch.
Amorphous hlau ua li cas?
Amorphous hlau yog tsim los ntawm kev poob siab khov ntawm cov hlau nplaumCov atoms tsis muaj sijhawm los tsim cov iav crystalline thiab ua kom muaj kev sib haum xeeb (amorphous). Txij li cov theem hloov ntawm cov kua mus rau cov khoom yog suppressed nyob rau hauv cov txheej txheem no, tsis muaj crystallization nuclei yog tsim thaum solidification.
Vim li cas thiaj nyuaj ua amorphous hlau?
Vim tias tsis muaj cov dav hlau ntawm atoms hauv cov khoom siv amorphous, cov atoms yog gridlocked rau hauv cov qauv iav, ua rau kev txav ntawm pawg ntawm atoms nyuaj heev. Ib qho txiaj ntsig ntawm qhov no atomic gridlock, yog tias qee cov hlau amorphous nyuaj heev. Liquidmetal® yog ntau dua ob zaug nyuaj dua stainless hlau.
Thaum twg yog kua hlau tsim?
Atakan Peker ntawm Liquidmetal Technologies, Lake Forest, Calif. Peker ntxiv tau pab Johnson tsim lub tswv yim ntawm kev tsim cov kua hlau tuab uas tsim iav yam tsis tas yuav tsum tau ua kom txias sai. Johnson tau pib ua haujlwm hauv thaj chaw thaum ntxov 1980s nrog cov npoj yaig ntawm NASA's Jet Propulsion Laboratory.
Puas yog hlau amorphous?
Ib yam amorphous hlau yog an alloy ntawm hlau nrog boron thiab silicon Amorphous hlau los ntawm cov neeg muab khoom no hauv daim ntawv nyias (25-microns tuab) ribbon lossis ntawv ci. Daim ntawv no tshwm sim ncaj qha los ntawm cov txheej txheem siv los tsim cov hlau: Molten hlau drips mus rau lub log uas muaj cov ntshiab molybdenum.

Cov kab hlau ua hlau tsim nyob qhov twg?
Banded hlau formations yog xav tias tau tsim nyob rau hauv hiav txwv dejvim qhov tshwm sim ntawm oxygen tsim los ntawm photosynthetic cyanobacteria. Cov pa oxygen ua ke nrog cov hlau yaj hauv lub ntiaj teb dej hiav txwv los tsim cov hlau tsis huv, uas tau los nag, tsim ib txheej nyias ntawm cov dej hiav txwv .
Vim li cas ib yam khoom hlau tsis muaj hlau nplaum nyiam rau cov hlau nplaum?
Thaum cov hlau nplaum raug coj los ze rau cov khoom siv ferromagnetic yav dhau los uas tsis muaj hlau nplaum, nws ua rau cov hlau nplaum hauv zos ntawm cov khoom uas tsis zoo li cov ncej ze tshaj, ib yam li hauv. unmagnetized khoom rau cov hlau nplaum raws li daim duab hauv .
Leej twg tsim lub dav hlau deicing?
Kev ua haujlwm tau pib los ntawm retired Ph. D chemist, William C. Geer. Hauv nws qhov kev tshawb nrhiav los tsim cov khau khiab deicing, lub tuam txhab tau tsim lub tsev loj hauv Akron kom rov ua dua huab cua phem thiab icing ntawm lub dav hlau tis .
Leej twg tsim lub dav hlau ua ntej wright cov kwv tij?
thawj lub tshuab ya tau tsim los ntawm Indian kws tshawb fawb Shivkar Bapuji Talpadethiab tsis yog Wright Cov Kwv Tij, Tus Thawj Fwm Tsav Tebchaws Satya Pal Singh tau hais, thiab nws ntseeg tias qhov no yuav tsum tau qhia hauv Is Nrias teb.
Leej twg tsim lub dav hlau?
thawj lub nkoj dav hlau, "Ugly Duckling" tau tsim xyoo 1905 los ntawm Alexander Graham Tswb. Airboats tom qab ntawd tau qhia rau South Florida hauv xyoo 1920 los ntawm Glenn Curtis ua txoj hauv kev zoo rau cov neeg tuaj tshiab los tshawb txog cov swamplands .
