Saynis yahanadu waxay xakameeyaan xiisadda dusha sare si ay u maamulaan birta dareeraha ah (muuqaal leh)

Cilmi-baarayaal ka tirsan Jaamacadda Waqooyiga Carolina ayaa soo saaray hab lagu xakameynayo xiisadda dusha sare ee biraha dareeraha ah iyadoo la adeegsanayo koronto aad u hooseeya, albaabka u furaya jiil cusub oo wareegyo elektiroonig ah oo dib loo habeyn karo, anteenooyinkooda iyo teknoolojiyadda kale.Habkani wuxuu ku tiirsan yahay xaqiiqda ah in oksaydhka "maqaarka" ee birta, kaas oo la dhigi karo ama laga saari karo, u dhaqmo sida surfactant, yaraynta xiisadda dusha sare ee u dhaxaysa birta iyo dareeraha ku wareegsan.googletag.cmd.push(shaqo() {googletag.display('div-gpt-ad-1449240174198-2');});
Cilmi-baadhayaashu waxay isticmaaleen bir dareere ah oo gallium iyo indium ah.Substrate-ka, daawaha qaawan waxa uu leeyahay kacsanaan aad u sarreeya oo dusha sare ah, qiyaastii 500 millinewtons (mN)/mitir, taas oo keenta in birta ay samaysato balastar wareegsan.
Laakiin waxaan ogaanay in codsiga lacag yar oo togan - in ka yar 1 volt - ay sababtay fal-celin elektrokimiko ah oo sameeyay lakabka oksaydhka ee dusha sare ee birta, taas oo si weyn hoos ugu dhigtay xiisadda dusha sare ee 500 mN / m ilaa 2 mN / m.”ayuu yiri Michael Dickey, Ph.D., borofisar ku-xigeenka injineerinka kiimikada iyo biomolecular ee Waqooyiga Carolina iyo qoraaga sare ee warqadda qeexaysa shaqada."Isbeddelkan wuxuu keenaa birta dareeraha ah inay u fidiso sida canjeelada oo hoos timaada xoogga cufnaanta."
Cilmi-baarayaashu waxay sidoo kale muujiyeen in isbeddelka xiisadda dusha sare ay tahay mid dib loo celin karo.Haddii cilmi-baarayaashu ay beddelaan polarity ee kharashka laga bilaabo togan ilaa taban, oksaydhka waa la saaraa oo xiisadda sare ee dusha sare ayaa soo noqotaa.Xiisadda dusha sare ayaa lagu hagaajin karaa inta u dhaxaysa labadan daraf iyadoo lagu beddelayo walaaca xoogaa yar.Waxaad ka daawan kartaa fiidiyowga farsamada hoos.
"Isbeddelka ka dhashay xiisadda dusha sare waa mid ka mid ah kuwii ugu weynaa ee abid la diiwaan geliyo, taas oo ah mid cajiib ah marka loo eego in lagu xakameyn karo wax ka yar volt," ayuu yiri Dickey."Waxaan u isticmaali karnaa farsamadan si aan u xakameyno dhaqdhaqaaqa biraha dareeraha ah, taas oo noo ogolaaneysa inaan bedelno qaabka anteenooyinka oo aan samayno ama jebinno wareegyada.Waxa kale oo loo isticmaali karaa kanaalada microfluidic, MEMS, ama qalabka sawir-qaadista iyo indhaha.Qalab badan ayaa sameeya oksaydhyada dusha sare, markaa shaqadan waxaa lagu kordhin karaa meel ka baxsan biraha dareeraha ah ee halkan lagu barto.
Shaybaadhka Dickey ayaa hore u muujiyay habka birta dareeraha ah ee "3D printing" kaas oo isticmaala lakabka oksaydhka ah ee ku samaysan hawada si uu uga caawiyo birta dareeraha ah inay sii haysato qaabkeeda - oo la mid ah waxa lakabka oksaydhku ku sameeyo daawaha xalka alkaline..
"Waxaan u maleyneynaa in oxides ay u dhaqmaan si ka duwan jawiga aasaasiga ah marka loo eego hawada deegaanka," ayuu yiri Dickey.
