Az Edinburgh-i Heriot-Watt Egyetem munkat\u00e1rsai a Kelet-k\u00ednai M\u0171szaki Egyetem tud\u00f3sai k\u00f6z\u00f6sen laborat\u00f3riumban szintetiz\u00e1lt\u00e1k az \u00fajfajta anyagot. K\u00e9t l\u00e9p\u00e9sben \u00e1ll\u00edtott\u00e1k el\u0151: el\u0151sz\u00f6r h\u00e1romsz\u00f6g\u0171 \u00e9p\u00edt\u0151elemeket hoztak l\u00e9tre, majd ebb\u0151l tetra\u00e9der alak\u00fa molekul\u00e1t. A keletkez\u0151 anyag er\u0151sen vonzza, majd mag\u00e1ba z\u00e1rva meg is tartja az olyan \u00fcvegh\u00e1zhat\u00e1s\u00fa g\u00e1zokat, mint amilyen p\u00e9ld\u00e1ul a sz\u00e9n-dioxid. A vizsg\u00e1latok alapj\u00e1n a molekula v\u00edzben is stabil \u2013 ez j\u00f3 h\u00edr ipari felhaszn\u00e1l\u00e1shoz, ahol nedves k\u00f6rnyezetben kell megk\u00f6tni a szenet.<\/p>\n\n\n\n

A laborat\u00f3rium elv\u00e9gzett vizsg\u00e1latok azt mutatj\u00e1k, hogy a molekulaszerkezet k\u00e9pes mag\u00e1ba z\u00e1rni a k\u00e9n-hexafluoridot is, amit jelenleg a leger\u0151sebb \u00fcvegh\u00e1zhat\u00e1s\u00fa g\u00e1zk\u00e9nt tartanak sz\u00e1mon a tud\u00f3sok \u2013 emelik ki a Nature Synthesis c\u00edm\u0171 tudom\u00e1nyos lapban publik\u00e1lt tanulm\u00e1nyban.<\/p>\n\n\n\n

M\u00edg a sz\u00e9n-dioxid 5\u2013200 \u00e9v k\u00f6z\u00f6tti ideig marad fenn a l\u00e9gk\u00f6rben, addig a k\u00e9n-hexafluorid 800\u20133200 \u00e9v alatt t\u0171nik csak el onnan. Vagyis hi\u00e1ba van bel\u0151le kevesebb, mint a sz\u00e9n-dioxidb\u00f3l, rendk\u00edv\u00fcl hossz\u00fa \u00e9lettartama miatt 23 500-szor er\u0151sebb hat\u00e1st gyakorol a felmeleged\u00e9sre, mint a sz\u00e9n-dioxid.<\/p>\n\n\n\n

A jelenlegi sz\u00e1m\u00edt\u00e1sok szerint egy\u00e9bk\u00e9nt \u00e9vente 20 milli\u00e1rd tonna sz\u00e9n-dioxidot kellene kivonnunk a l\u00e9gk\u00f6rb\u0151l ahhoz, hogy ellens\u00falyozzuk a kibocs\u00e1t\u00e1st, ami viszont \u00e9vr\u0151l \u00e9vre emelked\u0151 tendenci\u00e1t mutat. A jelenlegi strat\u00e9gi\u00e1kkal \u00e9vente 2 milli\u00e1rd tonn\u00e1val lehet tehermentes\u00edteni a l\u00e9gk\u00f6rt, de ezt t\u00f6bbnyire a f\u00e1k \u00e9s a talaj teszi meg. Az \u00faj technol\u00f3gi\u00e1k, mint p\u00e9ld\u00e1ul a sz\u00e9n-dioxidot elnyel\u0151 rendszerek 2,3 milli\u00f3 tonn\u00e1val j\u00e1rulnak hozz\u00e1 ehhez.<\/p>\n\n\n\n

Az olyan anyagok, mint a most l\u00e9trehozott molekula nagym\u00e9rt\u00e9kben seg\u00edthet kataliz\u00e1lni a sz\u00e9n-dioxid megk\u00f6t\u00e9s\u00e9t, ami nagy seg\u00edts\u00e9g lehet a glob\u00e1lis felmeleged\u00e9s elleni harcban.<\/p>\n\n\n\n
