Thaum lub sijhawm cua daj cua dub loj xyoo 1998, cov dej khov khov rau ntawm cov kab hluav taws xob thiab cov ncej, ua rau tuag tes tuag taw rau sab qaum teb Tebchaws Meskas thiab sab qab teb Canada, ua rau ntau qhov txias thiab tsaus rau hnub thiab txawm lub lis piam.Txawm hais tias nws yog cua turbines, lub zog yees, drones lossis lub dav hlau tis, kev sib ntaus sib tua tiv thaiv dej khov feem ntau tso siab rau txoj kev siv sijhawm, kim thiab / lossis siv ntau lub zog thiab ntau yam tshuaj.Tab sis saib ntawm qhov xwm txheej, McGill cov kws tshawb fawb xav tias lawv tau pom txoj hauv kev tshiab los daws qhov teeb meem.Lawv tau txais kev tshoov siab los ntawm cov tis ntawm gentoo penguins, cov penguins uas ua luam dej hauv cov dej khov ntawm thaj av Antarctic, uas nws cov plaub tsis khov txawm tias qhov kub ntawm sab nrauv zoo hauv qab khov.
Peb xub tshawb xyuas cov khoom ntawm lotus nplooj, uas yog zoo heev ntawm wicking dej, tab sis nws muab tawm hais tias lawv tsis tshua muaj txiaj ntsim ntawm wicking dej.hais tias Ann Kitzig, tus kws tshaj lij ntawm kev tsim tshuaj lom neeg ntawm McGill University thiab tus thawj coj ntawm Biomimetic Surface Engineering Lab, uas tau nrhiav kev daws teeb meem rau ze li kaum xyoo, cov khoom siv uas tuaj yeem tshem tawm dej thiab dej khov.“
Daim duab sab laug qhia tau hais tias lub microscopic qauv ntawm penguin feather (10-micron ze-up ntawm lub ntxig yog sib npaug rau 1/10 qhov dav ntawm tib neeg cov plaub hau, muab lub tswv yim ntawm nplai).los ntawm ceg plaub."Hooks" yog siv los koom nrog cov plaub hau plaub hau ua ke los tsim cov ntaub pua plag.Ntawm sab xis yog cov hlau tsis muaj hlaudaim ntaubuas cov kws tshawb fawb tau embellished nrog nanogrooves, replicating lub hierarchy ntawm penguin feather qauv (hlau hlau nrog nanogrooves rau saum).
"Peb pom tias cov txheej txheej ntawm cov plaub hau lawv tus kheej muab cov dej ntws tawm, thiab lawv qhov chaw serrated txo cov dej khov," piav qhia Michael Wood, tus tub ntxhais kawm tiav tsis ntev los no ua haujlwm nrog Kitziger, uas yog ib tus kws sau ntawv ntawm txoj kev tshawb no.Cov kws sau ntawv tau luam tawm ib tsab xov xwm tshiab hauv ACS Applied Material Interfaces."Peb muaj peev xwm rov ua dua cov teebmeem no nrog laser-txiav hlau mesh."
Kitzig tau hais ntxiv tias: "Nws yuav zoo li qhov tsis txaus ntseeg, tab sis tus yuam sij rau cov dej khov yaj yog tias tag nrho cov qhov hws ntawm lub mesh nqus dej hauv cov dej khov.Cov dej hauv cov qhov hws no yog qhov kawg kom khov, thiab thaum nws nthuav dav, nws tsim cov kab nrib pleb zoo li qhov koj pom hauv lub tub yees lub thawv dej khov.Peb xav tau kev siv zog me ntsis kom tshem tawm cov dej khov los ntawm kab sib chaws, vim tias cov kab nrib pleb hauv txhua lub qhov tau yooj yim meander raws li qhov chaw ntawm cov xov hlau braided.
Cov kws tshawb fawb tau ua qhov ntsuas cua ntawm qhov chaw stenciled thiab pom tias kev kho mob yog 95 feem pua ​​​​zoo dua ntawm kev tiv thaiv icing dua li unclad polished stainless hlau panels.Txij li tsis muaj kev kho tshuaj lom neeg yuav tsum tau ua, txoj kev tshiab muaj peev xwm kho tsis tau cov kev daws teeb meem ntawm kev tsim dej khov ntawm cov cua turbines, cov ncej fais fab, cov kab hluav taws xob thiab cov drones.
"Raws li tus naj npawb ntawm cov neeg caij dav hlau txoj cai lij choj thiab cov kev pheej hmoo cuam tshuam, nws tsis zoo li tias lub dav hlau dav hlau yuav tsuas yog qhwv hauv hlau.mesh, ”Kitzig ntxiv."Txawm li cas los xij, muaj ib hnub saum npoo ntawm lub dav hlau tis yuav muaj qhov zoo nkauj uas peb tab tom kawm, thiab kev txiav txim siab yuav tshwm sim los ntawm kev sib xyaw ua ke ntawm cov txheej txheem de-icing ua haujlwm ua ke ntawm tis.Qhov saum npoo muaj xws li textures tshwm sim los ntawm penguin tis..surface texture."
"Txhim kho qhov chaw tiv thaiv icing raws li kev ua haujlwm dual - ice flaking los ntawm microstructure thiab cov kua dej txhim kho los ntawm nanostructure", los ntawm Michael J. Wood, Gregory Brock, Juliette Debret, Philippe Servio thiab Anne-Marie Kitzig, luam tawm hauv ACS Appl.matt.interface
Founded hauv Montreal, Quebec hauv 1821, McGill University yog Canada tus naj npawb ib lub tsev kawm kho mob.McGill yog qhov tsis tu ncua ntawm cov tsev kawm qib siab zoo tshaj plaws hauv lub tebchaws thiab lub ntiaj teb.Nws yog "lub ntiaj teb nto moo" lub tsev kawm ntawv qib siab nrog kev tshawb fawb txog kev ua haujlwm thoob plaws peb lub tsev kawm ntawv, 11 chav haujlwm, 13 lub tsev kawm txuj ci, 300 txoj kev kawm thiab ntau dua 40,000 cov tub ntxhais kawm, suav nrog ntau dua 10,200 cov tub ntxhais kawm tiav.McGill nyiam cov tub ntxhais kawm los ntawm ntau dua 150 lub teb chaws, thiab nws 12,800 cov tub ntxhais kawm thoob ntiaj teb ua 31% ntawm nws cov tub ntxhais kawm lub cev.Ntau tshaj li ib nrab ntawm McGill cov tub ntxhais kawm yog cov neeg hais lus ntawm niam hom lus uas tsis yog lus Askiv, thiab kwv yees li 19 feem pua ​​​​ntawm cov tub ntxhais kawm no suav tias yog Fabkis ua lawv thawj hom lus.
