Uguquko lwesayensi ekufakweni kwethambo

Iqembu labacwaningi lenze indlela entsha yokuhlanganisa amathambo, egqugquzelwa amaphiko ojekamanzi, ama-cicada, noma ama-cicada.

Ukumbozwa okusha kubonakala yiqiniso lokuthi kuqeda amagciwane ayingozi futhi kungaxwayisa ngokwehluleka ukufakelwa kabusha okuseduze, ngokusho kwanyatheliswa yi-website ye-New Atlas, ecaphuna iphephabhuku le-Science.

Ukulingiswa kwemvelo

I-Biomimicry, okungukuthi, ukukhiqizwa kwezinto ezenziwe ngabantu ngokusekelwe ekubonweni kwemvelo yemvelo, kuye kwaba umshayeli onamandla wokuqamba izinto ezintsha emphakathini wezokwelapha iminyaka.

Impahla engaholela ekwakhiweni okungcono kwamathambo isivele idaliwe, iphefumulelwe izinhlobo ezahlukene zama-pores ezitholakala ezinkuni nezimpondo zezilwane.

Kukhona futhi inzwa ephefumulelwe i-cactus engaqoqa umjuluko ukuze ihlaziywe kanye nokumbozwa kokusebenza kobuchopho ngokusekelwe emaqabunga esitshalo se-carnivorous pitcher.

Ukubuyela emuva ekulingiseni imvelo futhi, abacwaningi baseNyuvesi yase-Illinois bebecwaninga ngamaphiko amelana namagciwane ojekamanzi nama-cicadas ukuze bakhe into entsha engasiza ekuxazululeni izinkinga zokutheleleka ngamagciwane okuvame ukwenzeka ekufakweni kwamathambo.

Into esebenzayo

Ngokomcwaningi ophambili walolu cwaningo, uProfessor we-Materials Science and Engineering u-University of Illinois, u-Cheng Kau, ibingekho indlela efanele yokubhekana nezifo ezihlasela iziguli ezifakelwa amathambo namalunga ezingafinyelela ku-10%.

USolwazi Cao uthe imizamo yamanje yokusebenzisa ama-ion ensimbi esindayo ukulwa namagciwane ingabangela nomonakalo ezicutshini eziseduze, futhi izifakelo ezifakwe ngama-antibiotic zigcina zingaphumeleli lapho amakhemikhali ephela.

Futhi awasebenzi ngokumelene namagciwane amelana nama-antibiotic, okuyinkinga ekhulayo emhlabeni wezokwelapha.

indlela yokwenza imishini

Ngakho-ke u-Cao nethimba lakhe locwaningo bakha i-foil coating yokufakelwa kwezokwelapha, ehlanganisa uhlangothi olulodwa lwama-nanobeam afana nalawo atholakala emaphikweni ezinambuzane ezibulala amangqamuzana e-bacterial lapho ehlangana nawo.

"Ukusebenzisa indlela yomshini ukubulala amagciwane kuvumela izinkinga eziningi nezindlela zamakhemikhali ukuba zidlule, kuyilapho kunikeza ukuguquguquka okudingekayo ukuze kufakwe izinto zokumboza ezindaweni ezithuthukisiwe," kusho uProfesa Jie Lau, uProfesa wePathology Biology, umbhali ngokubambisana we funda.

Ababili kweyodwa

Akukhona nje ukuthi abacwaningi baxazulula inkinga eyodwa ngokufakwa kwamathambo, baqaphela ukuthi ukumbozwa kwabo kungaxazulula enye: ukutholwa kusenesikhathi kokwehluleka kokufakelwa.

UCao uchaze ukuthi le nkinga ithinta cishe amaphesenti ayishumi azo zonke iziguli ezithola ukufakelwa.

Abacwaningi banamathisele ama-microsensors aguquguqukayo ngakolunye uhlangothi lwengubo ekwazi ukukala ukucindezeleka komshini kuma-implants, lapho i-coating ibekwe khona. Abacwaningi bathi kuvumela odokotela ukuthi babone ukuthi umzimba ululama kanjani eduze nokufakelwa, futhi bangathumela izexwayiso uma ingcindezi ekuhlanganyeleni okwenziwe iphezulu kakhulu. Abacwaningi okwamanje basebenzela isisombululo esingenantambo ukuze banikeze umthombo wamandla wangaphandle we-coating.
