Cov kws tshawb fawb ntawm North Carolina State University tau tsim ib txoj hauv kev los tswj qhov nro ntawm cov kua hlau los ntawm kev siv cov hluav taws xob tsis tshua muaj hluav taws xob, qhib lub qhov rooj rau lub cim tshiab ntawm cov hluav taws xob hluav taws xob, cov kav hlau txais xov thiab lwm yam thev naus laus zis.Txoj kev no tso siab rau qhov tseeb tias oxide "daim tawv nqaij" ntawm cov hlau, uas tuaj yeem tso lossis tshem tawm, ua raws li surfactant, txo qhov nro ntawm cov hlau thiab cov kua dej ib puag ncig.googletag.cmd.push(function() { googletag.display('div-gpt-ad-1449240174198-2′); });
Cov kws tshawb fawb tau siv cov kua hlau alloy ntawm gallium thiab indium.Nyob rau hauv lub substrate, lub liab qab alloy muaj qhov nro siab heev, kwv yees li 500 millinewtons (MN) / me me, uas ua rau cov hlau ua cov tshuaj pleev ib ce.
"Tab sis peb pom tias daim ntawv thov ntawm qhov zoo me me - tsawg dua 1 volt - ua rau cov tshuaj tiv thaiv electrochemical uas tsim cov oxide txheej ntawm cov hlau, uas txo qhov nro ntawm 500 mN / m mus txog 2 mN /. m."hais tias Michael Dickey, Ph.D., associate professor of chemical and biomolecular engineering ntawm North Carolina State thiab tus kws sau ntawv laus ntawm daim ntawv piav qhia txog kev ua haujlwm."Qhov kev hloov pauv no ua rau cov kua hlau nthuav dav zoo li pancake nyob rau hauv lub zog ntawm lub ntiajteb txawj nqus."
Cov kws tshawb fawb kuj tau pom tias qhov kev hloov pauv ntawm qhov nro ntawm qhov chaw yog thim rov qab.Yog tias cov kws tshawb fawb hloov qhov polarity ntawm tus nqi ntawm qhov zoo mus rau qhov tsis zoo, cov oxide raug tshem tawm thiab qhov siab ntawm qhov nro rov qab los.Qhov nro saum npoo tuaj yeem hloov kho ntawm ob qhov kev kub ntxhov no los ntawm kev hloov cov kev ntxhov siab me me.Koj tuaj yeem saib cov yees duab ntawm cov txheej txheem hauv qab no.
Dickey tau hais tias "Qhov kev hloov pauv tshwm sim hauv qhov nro yog ib qho loj tshaj plaws uas tau sau tseg, uas yog qhov zoo tshaj plaws vim tias nws tuaj yeem tswj tau tsawg dua li volt," Dickey tau hais."Peb tuaj yeem siv cov txheej txheem no los tswj cov kev txav ntawm cov hlau ua kua, uas tso cai rau peb hloov cov duab ntawm cov kav hlau txais xov thiab ua los yog tawg circuits.Nws kuj tseem siv tau rau hauv microfluidic channels, MEMS, lossis photonic thiab optical li.Ntau cov ntaub ntawv tsim oxides saum npoo, yog li txoj haujlwm no tuaj yeem txuas ntxiv mus dhau cov kua hlau kawm ntawm no. "
Dickey lub chaw kuaj mob yav dhau los tau ua kom pom cov kua hlau "3D luam ntawv" txoj kev uas siv cov txheej txheem oxide uas tsim hauv huab cua los pab cov kua hlau khaws nws cov duab - zoo ib yam li cov txheej txheem oxide ua nrog cov hlau hauv cov tshuaj alkaline..
Dickey tau hais tias "Peb xav tias cov oxides coj txawv txawv hauv qhov chaw ib puag ncig dua li hauv huab cua puag ncig," Dickey tau hais.
Cov ntaub ntawv ntxiv: Tsab ntawv "Giant thiab hloov tau qhov dej ntawm cov hlau ua kua los ntawm oxidation saum npoo" yuav tshaj tawm hauv Is Taws Nem rau lub Cuaj Hlis 15 hauv Kev Ua Haujlwm ntawm National Academy of Sciences:
