Vatsvagiri vepaNorth Carolina State University vakagadzira nzira yekudzora kushushikana kwepasi kwesimbi yemvura nekushandisa yakaderera voltages, kuvhura musuwo kune chizvarwa chitsva cheanogadziriswa emagetsi maseketi, antenna uye humwe hunyanzvi.Iyi nzira inoenderana nekuti iyo oxide "ganda" resimbi, iro rinogona kuiswa kana kubviswa, rinoita se surfactant, richideredza kusawirirana kwepamusoro pakati pesimbi nemvura yakatenderedza.googletag.cmd.push(basa() {googletag.display('div-gpt-ad-1449240174198-2′);});
Vatsvakurudzi vakashandisa mvura yesimbi alloy ye gallium uye indium.Muchikamu chepasi, alloy yakashama ine tension yakakwira zvakanyanya, ingangoita 500 milinewtons (mN)/mita, izvo zvinoita kuti simbi iite spherical patches.
"Asi takaona kuti kushandiswa kwechaji diki yakanaka - isingasviki 1 volt - yakakonzera kuita kweelectrochemical reaction yakagadzira oxide layer pamusoro pesimbi, iyo yakaderedza zvakanyanya tension yepasi kubva pa500 mN/m kusvika pa2 mN/ m."akadaro Michael Dickey, Ph.D., akabatana napurofesa wemakemikari uye biomolecular engineering kuNorth Carolina State uye munyori mukuru webepa rinotsanangura basa."Shanduko iyi inoita kuti simbi yemvura iwedzere sepancake pasi pesimba regiravhiti."
Vatsvakurudzi vakaratidzawo kuti kuchinja kwekusagadzikana kwepamusoro kunogadziriswa.Kana vatsvakurudzi vakashandura polarity yechaji kubva kune yakanaka kuenda kune yakaipa, okisidi inobviswa uye kushushikana kwepamusoro kunodzoka.Kushushikana kwepamusoro kunogona kugadziriswa pakati pezviviri izvi zvakanyanyisa nekushandura kushushikana muzvikamu zviduku.Iwe unogona kutarisa vhidhiyo yehunyanzvi pazasi.
"Kuchinja kunoguma mukukakavadzana kwepamusoro ndeimwe yezvakakura zvakambonyorwa, izvo zvinoshamisa zvakapiwa kuti zvinogona kudzorwa zvishoma pane volt," akadaro Dickey."Tinogona kushandisa hunyanzvi uhu kudzora kufamba kwesimbi dzemvura, izvo zvinotibvumira kushandura chimiro cheantenna uye kugadzira kana kutyora maseketi.Inogona zvakare kushandiswa mune microfluidic chiteshi, MEMS, kana photonic uye optical zvishandiso.Zvishandiso zvakawanda zvinoumba maokisidi epamusoro, saka basa iri rinogona kuwedzerwa kupfuura simbi dzemvura dzakadzidzwa pano. "
Dickey's lab yakamboratidza simbi yemvura "3D kudhinda" nzira inoshandisa oxide layer inoumba mumhepo kubatsira simbi yemvura kuchengetedza chimiro chayo - zvakafanana nezvinoitwa neoxyde layer ine alloy mune alkaline solution..
"Isu tinofunga kuti maokisidhi anoita zvakasiyana munzvimbo dzakakosha kupfuura mumhepo yakadzika," akadaro Dickey.
Ruzivo rwekuwedzera: Chinyorwa "Giant uye chinoshanduka chepamusoro chiitiko chesimbi yemvura kuburikidza nepamusoro oxidation" chichaburitswa paInternet munaGunyana 15 mune Proceedings yeNational Academy yeSainzi:
Kana ukasangana netaipa, zvisizvo, kana kuti uchida kutumira chikumbiro chekugadzirisa zviri papeji ino, ndapota shandisa fomu iri.Pamibvunzo yakajairika, ndapota shandisa fomu redu rekuonana.Kuti uwane mhinduro, ndapota shandisa chikamu cheruzhinji pazasi (kurudziro ndapota).
Mhinduro yako yakakosha kwatiri.Nekudaro, nekuda kwehuwandu hwemeseji, hatigone kuvimbisa mhinduro dzemunhu mumwe nemumwe.
