Anthu atayamba kutumiza matumba a mbatata kwa wopanga, Vaux, kutsutsa kuti matumbawo sanagwiritsidwenso ntchito mosavuta, kampaniyo idazindikira izi ndikuyambitsa malo osonkhanitsira. Koma zoona zake n’zakuti dongosolo lapadera limeneli limangothetsa kachigawo kakang’ono ka phiri la zinyalala. Chaka chilichonse, Vox Corporation yokha imagulitsa matumba oyika mabiliyoni 4 ku UK, koma matumba oyikapo 3 miliyoni okha ndi omwe amakonzedwanso mu pulogalamu yomwe tatchulayi, ndipo sanakonzedwenso kudzera mu pulogalamu yobwezeretsanso m'nyumba.
Tsopano, ofufuza akuti mwina abwera ndi njira ina yatsopano yobiriwira. Filimu yachitsulo yomwe imagwiritsidwa ntchito m'matumba oyikapo chip cha mbatata, mipiringidzo ya chokoleti ndi zoyika zina ndizothandiza kwambiri pakusunga chakudya chouma komanso chozizira, koma chifukwa amapangidwa ndi zigawo zingapo za pulasitiki ndi zitsulo zophatikizidwa pamodzi, zimakhala zovuta kuzibwezeretsanso. ntchito.
"Chikwama cha chip cha mbatata ndi phukusi laukadaulo wapamwamba kwambiri." adatero Dermot O'Hare waku Oxford University. Komabe, ndizovuta kwambiri kuzibwezeretsanso.
Bungwe lotayira zinyalala ku Britain la WRAP linanena kuti ngakhale tikulankhula mwaukadaulo, mafilimu achitsulo amatha kubwezeretsedwanso pamafakitale, malinga ndi momwe chuma chikuyendera, pakadali pano sizingatheke kubwezeredwanso.
Njira ina yomwe O'Hare ndi mamembala a timu yapanga ndi kanema woonda kwambiri wotchedwa nanosheet. Zimapangidwa ndi amino acid ndi madzi ndipo zimatha kupakidwa filimu yapulasitiki (polyethylene terephthalate, kapena PET, mabotolo ambiri amadzi apulasitiki amapangidwa ndi PET). Zotsatira zofananira zidasindikizidwa mu "Nature-Communication" masiku angapo apitawo.
Chosakaniza chosavulaza ichi chikuwoneka kuti chimapangitsa kuti zinthu zikhale zotetezeka kuti zisungidwe chakudya. "Malingaliro a mankhwala, kugwiritsa ntchito zinthu zopanda poizoni kupanga ma nanosheets opangira ndiwopambana." O'Hare anatero. Koma adanena kuti izi zidzadutsa nthawi yayitali yolamulira, ndipo anthu asayembekezere kuwona zinthuzi zikugwiritsidwa ntchito posungira chakudya osachepera zaka 4.
Chimodzi mwazovuta popanga zinthuzi ndikukwaniritsa zomwe makampani amafuna kuti pakhale chotchinga chabwino cha gasi kuti apewe kuipitsidwa ndikusunga zinthu zatsopano. Kuti apange ma nanosheets, gulu la O'Hare linapanga "njira yozunzika", ndiko kuti, kupanga labyrinth ya nano-level yomwe imapangitsa kuti zikhale zovuta kuti mpweya ndi mpweya wina uzifalikira.
Monga chotchinga cha okosijeni, machitidwe ake akuwoneka ngati pafupifupi nthawi 40 kuposa mafilimu opyapyala achitsulo, ndipo izi zimagwiranso ntchito bwino mu "mayeso opindika" amakampani. Kanemayo alinso ndi mwayi waukulu, ndiko kuti, pali chinthu chimodzi chokha cha PET chomwe chingasinthidwenso kwambiri.
