Mugihe c'Umuyaga Ukomeye wo mu 1998, kwiyongera kw'ibarafu ku mashanyarazi no ku nkingi byatumye amajyaruguru ya Amerika n'amajyepfo ya Kanada bihagarara, bituma abantu benshi bakonja n'umwijima mu minsi cyangwa ibyumweru.Yaba turbine z'umuyaga, iminara y'amashanyarazi, drone cyangwa amababa y'indege, de-icing akenshi ishingiye kuburyo butwara igihe, buhenze kandi / cyangwa bukoresha ingufu nyinshi hamwe nimiti itandukanye.Ariko urebye ibidukikije, abashakashatsi ba McGill batekereza ko babonye uburyo bushya butanga icyizere cyo gukemura ikibazo.Bahumekewe n'amababa ya pingwin ya gentoo yoga mu mazi yubukonje ya Antaragitika, kandi ubwoya bwabwo ntibukonja nubwo ubushyuhe bwo hanze buri munsi yubukonje.
Twabanje gukora iperereza ku miterere y’amababi ya lotus, akaba ari meza cyane mu gukuraho amazi, ariko byagaragaye ko adafite akamaro mu gukuraho urubura, ”ibi bikaba byavuzwe na Ann Kitzig, umaze imyaka igera ku icumi ashakisha ibisubizo kandi akaba umwungirije wungirije .Umuganga w’ubuhanga mu bya shimi muri kaminuza ya McGill, Umuyobozi wa Laboratoire y’Ubwubatsi bwa Biomimetic Surface Engineering: “Igihe twatangiraga gukora iperereza ku miterere y’amababa ya penguin, ni bwo twavumbuye ibintu bisanzwe bibaho icyarimwe bisuka amazi n’ibarafu.”
Uwitekaishushoibumoso yerekana microstructure yikibaba cya penguin (hafi-ya micron 10 yinjizamo ihuye na 1/10 cyubugari bwimisatsi yumuntu kugirango yumve igipimo).Utwo tubuto n'amashami ni ibiti byo hagati yamababa yishami..“Ibifuni” bikoreshwa muguhuza umusatsi wamababa kugiti cye hamwe kugirango ube umusego.Iburyo hari umwenda w'icyuma udafite ingese abashakashatsi bashushanyijeho nanogrooves, byerekana urwego rwimiterere y’amababa ya penguin (insinga ifite nanogrooves hejuru).
Michael Wood, umunyeshuri urangije vuba aha ukorana na Kitzig akaba n'umwe mu banditsi b'ubwo bushakashatsi abisobanura agira ati: “Twabonye ko gahunda ikurikirana y’amababa ubwayo itanga ibintu bisohora amazi, kandi hejuru yabyo bikagabanya gufatana urubura.”Ingingo nshya muri ACS Ikoreshwa ryibikoresho.Ati: "Twashoboye kwigana izo ngaruka hamwe na meshi yacishijwe mu cyuma."
Kitzig yongeyeho ati: “Birashobora gusa nkaho bivuguruzanya, ariko urufunguzo rwo gutandukanya urubura ni imyenge yose yo muri mesh ikurura amazi mu gihe cy'ubukonje.Amazi yo muri ibyo byobo amaherezo arakonja, kandi uko yaguka, atera ibice, nkuko waba uri muri firigo.Ni kimwe no kugaragara muri ice cube tray.Dukeneye imbaraga nke cyane kugira ngo dukure urubura kuri meshi yacu kuko ibice biri muri ibyo byobo bikunda kugenda hirya no hino hejuru y'izo nsinga. ”
Abashakashatsi bapimye hejuru y’umuyaga mu muyoboro w’umuyaga basanga uburyo bwo kuvura bwari bwiza 95% mu kurwanya ibicu kuruta impapuro zipfunyitse zidafite ingese.Kubera ko nta muti w’imiti usabwa, uburyo bushya butanga igisubizo gishobora kubungabungwa ku kibazo cy’ibarafu ry’umuyaga, iminara, imirongo y’amashanyarazi na drone.
Kitzig yongeyeho ati: "Ukurikije umubare w'amabwiriza agenga indege zitwara abagenzi hamwe n'ingaruka ziterwa nayo, ntibishoboka ko amababa y'indege azapfunyika gusa mu cyuma."Ati: "Birashoboka ariko ko umunsi umwe hejuru yikibaba cyindege gishobora kuba gifite imyigire twiga, kandi kubera ko uburyo bwa de-icing gakondo bukorera hamwe hejuru yibaba, de-icing izabaho muguhuza amababa ya penguin.ahumekewe n'imiterere y'ubutaka. ”
“Ubuso bwizewe bwo kurwanya ibishushanyo bishingiye ku mikorere ibiri - urubura ruterwa na microstructure iterwa na nanostructure yongerewe imbaraga mu kurwanya amazi”, Michael J. Wood, Gregory Brock, Juliette Debre, Philippe Servio na Anne-Marie Kitzig muri ACS Appl.alma mater.imbere
Kaminuza ya McGill yashinzwe mu 1821 i Montreal, muri Québec, ni yo kaminuza ya mbere muri Kanada.Kaminuza ya McGill ihora ishyirwa muri kaminuza zikomeye haba mu gihugu ndetse no ku rwego mpuzamahanga.Nicyo kigo kizwi cyane mumashuri makuru hamwe nibikorwa byubushakashatsi bikikije ibigo bitatu, 11kaminuza, Amashuri makuru 13 yabigize umwuga, gahunda 300 yo kwiga hamwe n’abanyeshuri barenga 40.000, harimo n’abanyeshuri barenga 10.200.McGill ikurura abanyeshuri baturutse mu bihugu birenga 150, naho abanyamahanga bayo 12.800 bagize 31% byabanyeshuri.Kurenga kimwe cya kabiri cyabanyeshuri ba McGill bavuga ko ururimi rwabo rwa mbere atari icyongereza, naho 19% muri bo bavuga igifaransa nkururimi rwabo rwa mbere.
