Chikwereti chemufananidzo: ACS Applied Materials uye Interfaces
Mainjiniya paYunivhesiti yeMassachusetts Amherst vakagadzira ajirazvinokuchengeta uchidziya uchishandisa mwenje wemukati. Tekinoroji iyi mhedzisiro ye80-gore yekuda kugadzira machira zvichienderana nebheyafur. Tsvagiridzo iyi yakaburitswa mujenari ACS Applied Materials uye Interfaces uye parizvino yakagadziridzwa kuita chigadzirwa chekutengesa.
Polar bears anogara mune dzimwe nzvimbo dzakaoma zvikuru papasi uye haavhunduke neTembiricha yeArctic yakadzika seminus 45 degrees Celsius. Nepo mapere aine akati wandei ekuchinja anoatendera kuti abudirire kunyangwe tembiricha yadzikira, masayendisiti anga achitarisisa kuchinjika kwemvere dzawo kubva kuma1940s. Inoita sei polar berefururambe uchidziya?
Mhuka zhinji dzepolar dzinoshingaira kushandisa chiedza chezuva kuchengetedza tembiricha yemuviri wadzo, uye polar bear fur muenzaniso unozivikanwa. Kwemakumi emakore, masayendisiti akaziva kuti chimwe chezvakavanzika zvemapere mvere dzawo chena. Zvinowanzotendwa kuti mvere nhema dzinotora kupisa zvirinani, asi polar bere fur yakaratidza kuve inoshanda pakufambisa mwaranzi yezuva paganda.
Polar berefurirwondo rwechisikigo runoendesa chiedza chezuva kuganda rebere, rinotora chiedza uye kupisa bere. Uye thefurzvakare yakanaka kwazvo kudzivirira ganda rinodziya kuti risapise kupisa kwese kunenge kwakunda. Kana zuva rikapenya, zvakafanana negumbeze gobvu rinowanikwa kuti uzvidziye wobva wabata kudziya paganda rako.
Chikwata chekutsvagisa chakagadzira jira rine mativi maviri iro repamusoro rine shinda, senge berefur, fambisa chiedza chinooneka kune chikamu chepasi, icho chakagadzirwa nenylon uye chakaputirwa nechinhu chakasviba-ruvara chinonzi PEDOT. PEDOT inoita seganda rebheya kuti irambe ichidziya.
Bhachi rakagadzirwa kubva muchinhu ichi rakareruka ne30% kupfuura iro bhachi redonje rakafanana, uye chimiro chayo chechiedza uye kupisa chinoshanda zvakaringana kupisa muviri zvakananga uchishandisa mwenje wemukati uripo. Nekuisa simba zviwanikwa zvakapoteredza muviri kugadzira "mamiriro ekunze", nzira iyi inogadzikana kupfuura nzira dziripo dzekudziya nekudziya.
