Raws li txoj kev tshawb fawb tshiab coj los ntawm cov kws tshawb fawb ntawm Lub Tsev Haujlwm Saib Xyuas Zog Lawrence Berkeley National Laboratory (Berkeley Lab) thiab ntawm University of California, Berkeley, electrons hauv vanadium tau dioxide kev coj hluav taws xob tsis muaj ua cua sov.
Ib yam li ntawd ib tug yuav nug, yog Vanadium yog ib tug conductor ntawm tshav kub los yog hluav taws xob?
Rau cov electrons, kub yog random motion. Piv txwv li, thaum cov kws tshawb fawb ntxiv cov hlau tungsten rau vanadium dioxide, lawv txo qhov kub ntawm cov khoom siv los ua hlau, thiab kuj ua rau nws zoo dua kub conductor.
Qhov thib ob, dab tsi hlau tsis ua kom sov? Tus neeg pluag tshaj plaws ntawm kub ntawm hlau yog Bismuth. Stainless hlau yog ib o o yog tus neeg tsav tsheb tsis zoo ntawm kub , thiab koj siv qhov no ntau zaus hauv lub neej txhua hnub! Lwm cov neeg ua haujlwm tsis zoo suav nrog titanium, txhuas thiab chromium. Thiab feem ntau ironically, Mercury, kua hlau siv hauv cov ntsuas kub!
Qhov thib ob, puas yog vanadium ua hluav taws xob?
Vanadium dioxide muaj peev xwm hloov tau los ntawm kev pom los ntawm insulator mus rau cov hlau conductive ntawm qhov kub ntawm 67 degrees Celsius. Hais txog kev tsim cov hlau conductive, vanadium dioxide kuj tseem pheej yig rau kev tsim khoom vim nws xav tau qhov kub thiab txias los tsim.
Puas yog tag nrho cov hlau ua kom sov?
Hlau feem ntau ua cua sov zoo dua lwm cov khoom. Hauv hlau , ib co ntawm cov electrons yog tsis daig rau tus kheej atoms tab sis ntws ywj pheej ntawm cov atoms.

Dab tsi yog peb txheej ntawm cov hav zoov sov sov?
Layers of the Rainforest Cov rainforest tuaj yeem muab faib ua peb txheej: lub canopy, understory, thiab hav zoov pem teb. Cov tsiaj sib txawv thiab cov nroj tsuag nyob hauv txhua txheej sib txawv. Lub canopy - Qhov no yog txheej saum toj kawg nkaus ntawm cov ntoo. Cov ntoo no feem ntau yog tsawg kawg yog 100 feet siab
Dab tsi yog cov nroj tsuag tseem ceeb hauv hav zoov sov sov?
Siab, dav-leaved evergreen ntoo yog cov tseem ceeb nroj tsuag. Qhov chaw ntom ntom ntawm biodiversity yog pom nyob rau hauv hav zoov canopy, raws li nws feem ntau txhawb ib tug nplua nuj flora ntawm epiphytes, xws li orchids, bromeliads, mosses thiab lichens
Qhov twg yog qhov chaw sov sov savanna?
Lub Savanna biome yog Tropical grassland. Nws nyob nruab nrab ntawm ob lub ntsiab lus, Tropic ntawm Cancer mus rau sab qaum teb thiab Tropic ntawm Capricorn mus rau sab qab teb. Cov cheeb tsam nruab nrab ntawm lub tropics yog dab tsi hu ua tropical grasslands. Lub biome npog ntau dua ib nrab ntawm Africa, feem ntau ntawm South America thiab ib feem ntawm Asia xws li Is Nrias teb
Cov lasers puas tuaj yeem ua kom sov?
Cov kws tshawb fawb tau siv lub zog lasers kom sov cov khoom siv los ua ib feem ntawm kev siv zog los tsim fusion zog rau ntau xyoo. Thaum lasers siv los ua kom sov cov ntaub ntawv feem ntau, lub zog ntawm lub laser ua ntej heats li electrons nyob rau hauv lub hom phiaj
Dab tsi yog qhov ua rau lub ntiaj teb sov sov?
Qhov no deforestation yog qhov tseem ceeb tshaj plaws ntawm kev siv av hloov cuam tshuam rau lub ntiaj teb ua kom sov. Cov laj thawj tseem ceeb yog: kev rhuav tshem los ntawm kev siv av tas mus li hloov rau cov khoom ua liaj ua teb xws li nqaij nyug thiab xibtes roj (27%), hav zoov / cov khoom siv hav zoov (26%), kev cog qoob loo luv luv (24%), thiab hluav taws kub (23%)
