Vanhu pavakatanga kutumira mabhegi embatatisi kudzoka kumugadziri, Vaux, kupikisa kuti mabhegi akange asiri nyore kudzokororwa, kambani yakazviona uye yakatanga nzvimbo yekuunganidza. Asi chokwadi ndechekuti chirongwa ichi chakakosha chinongogadzirisa chikamu chidiki chegomo remarara. Gore rega rega, Vox Corporation chete inotengesa mabhiriyoni mana emabhegi ekurongedza kuUK, asi mamirioni matatu chete emabhegi ekurongedza anodzokororwa muchirongwa chataurwa pamusoro apa, uye haasati ashandiswa zvakare kuburikidza nechirongwa chekudzoreredza chemba.
Ikozvino, vaongorori vanoti vanogona kunge vauya neimwe itsva, yakasvibira. Firimu resimbi rinoshandiswa mumabhegi ekurongedzerwa embatatisi azvino, mabara echokoreti uye kumwe kurongedza kwechikafu rinobatsira kwazvo kuchengetedza chikafu chakaoma uye kuchitonhorera, asi nekuti akagadzirwa nemateru akati wandei epurasitiki nesimbi zvakabatanidzwa pamwechete, zvakaoma kudzokorora. use.
"Mbatatisi chip bag ndeyepamusoro-tech polymer packaging." akadaro Dermot O'Hare weOxford University. Zvisinei, zvakaoma zvikuru kuzvishandisa patsva.
Bazi rekutasa marara reBritish WRAP rakataura kuti kunyangwe tichitaura zvehunyanzvi, mafirimu esimbi anogona kudzokororwa padanho remaindasitiri, kubva pamaonero ehupfumi, parizvino hazvigoneke kuti zvishandiswezve.
Imwe nzira yakatsanangurwa naO'Hare nenhengo dzechikwata ifirimu rakatetepa rinonzi nanosheet. Inoumbwa neamino acids nemvura uye inogona kuputirwa pafirimu repurasitiki (polyethylene terephthalate, kana PET, mabhodhoro emvura akawanda epurasitiki anogadzirwa nePET). Mibairo inoenderana yakaburitswa mu "Nature-Communication" mazuva mashoma apfuura.
Ichi chinhu chisingakuvadzi chinoratidzika kunge chinoita kuti chinhu ive chakachengeteka pakurongedzerwa kwechikafu. "Kubva pakuona kwemakemikari, kushandiswa kwezvinhu zvisina muchetura kugadzira nanosheets ekugadzira ibudiriro." O'Hare akadaro. Asi akataura kuti izvi zvichapfuura nehurongwa hurefu hwekutonga, uye vanhu havafanire kutarisira kuona zvinhu izvi zvichishandiswa mukurongedza chikafu mukati memakore mana.
Chikamu chedambudziko mukugadzira chinyorwa ichi kuzadzisa zvinodiwa neindasitiri kune yakanaka gasi chipingamupinyi kudzivirira kusvibiswa uye kuchengetedza chigadzirwa chitsva. Kugadzira nanosheets, timu yeO'Hare yakagadzira "nzira inotambudza", kureva, kuvaka nano-level labyrinth inoita kuti zviome kuti okisijeni nemamwe magasi zvipararire mukati.
Sechivhariso cheokisijeni, kuita kwayo kunoratidzika kunge kwakapetwa ka40 kune kwemafirimu akatetepa esimbi, uye chinyorwa ichi chinoitawo zvakanaka muindasitiri ye "bending test". Iyo firimu zvakare ine mukana wakakura, ndiko kuti, pane imwe chete PET zvinhu zvinogona kudzokororwa zvakanyanya.
