Abaphandi kwiYunivesithi yaseNorth Carolina State baye baphuhlisa indlela yokulawula ukuxinezeleka komphezulu wesinyithi solwelo ngokusebenzisa i-voltages ephantsi kakhulu, ukuvula umnyango kwisizukulwana esitsha seesekethe ze-elektroniki ezinokuphinda ziqwalaselwe, ii-eriyali kunye nobunye ubugcisa.Le ndlela ixhomekeke kwinto yokuba i-oxide "isikhumba" setsimbi, esinokufakwa okanye sisuswe, sisebenza njenge-surfactant, sinciphisa ukunyanzeliswa komhlaba phakathi kwetsimbi kunye nolwelo olujikelezileyo.googletag.cmd.push(umsebenzi () {googletag.display('div-gpt-ad-1449240174198-2′);});
Abaphandi basebenzisa i-alloy yensimbi ye-gallium kunye ne-indium.Kwi-substrate, i-alloy engenanto inoxinzelelo oluphezulu kakhulu lomphezulu, malunga ne-500 millinewtons (mN) / imitha, ebangela ukuba isinyithi yenze iipetshi ezingqukuva.
"Kodwa sifumene ukuba ukusetyenziswa kwentlawulo encinci encinci - ngaphantsi kwe-volt ye-1 - kubangele ukusabela kwe-electrochemical eyakha i-oxide layer phezu kwesinyithi, eyanciphisa kakhulu ukunyanzeliswa komhlaba ukusuka kwi-500 mN / m ukuya malunga ne-2 mN / m.”utshilo uMichael Dickey, Ph.D., unjingalwazi onxulumene neekhemikhali kunye nobunjineli be-biomolecular kwi-North Carolina State kunye nombhali ophezulu wephepha elichaza umsebenzi."Olu tshintsho lubangela ukuba isinyithi samanzi sande njengepanekuku phantsi kwamandla omxhuzulane."
Abaphandi baphinde babonisa ukuba utshintsho kwixinzelelo lomphezulu lunokuguqulwa.Ukuba abaphandi batshintsha i-polarity yentlawulo ukusuka kwi-positive ukuya kwi-negative, i-oxide iyasuswa kwaye i-high surface tension ibuya.Uxinzelelo lomphezulu lunokulungelelaniswa phakathi kwezi zimbini zigqithise ngokutshintsha uxinzelelo ngokunyuka okuncinci.Ungayibukela ividiyo yobuchule obu ngezantsi.
"Utshintsho olubangelwayo kuxinzelelo lomphezulu yenye yezona zikhulu zirekhodiweyo, eziphawulekayo ukuba ziyakwazi ukulawulwa ngaphantsi kwe-volt," kusho uDickey.“Singasebenzisa obu buchule ukulawula ukuhamba kweentsimbi ezingamanzi, okusivumela ukuba sitshintshe imilo yee-eriyali kwaye senze okanye saphule iisekethe.Inokusetyenziswa kwakhona kwiitshaneli ze-microfluidic, i-MEMS, okanye izixhobo ze-photonic kunye ne-optical.Izinto ezininzi zenza ii-oxides ezingaphezulu, ngoko ke lo msebenzi unokwandiswa ngaphaya kweentsimbi ezingamanzi ezifundwe apha.
Ilebhu kaDickey iye yabonisa ngaphambili isinyithi esilulwelo "i-3D yoshicilelo" indlela esebenzisa umaleko we-oxide owenzela emoyeni ukunceda isinyithi esilulwelo sigcine imilo yayo - kuyafana noko kwenziwa ngumaleko we-oxide ngealloyi kwisisombululo sealkaline..
“Sicinga ukuba iioksidi ziziphatha ngendlela eyahlukileyo kwiindawo ezisisiseko kunasemoyeni,” utshilo uDickey.
