Hauv Namib Suab puam, nws yog ib qho chaw qhuav tshaj plaws hauv ntiaj teb. Nyob rau hauv cov suab puam, ib tug me me kab nce toj cov xuab zeb dunes, qaij nws lub cev mus rau cua, thiab ntes nws tsuas muaj dej los ntawm cov pos huab.
"Water shortage is a serious problem facing global communities," said Dr. Aida shahrokian, a candidate for Akron University. "If fog droplets can be successfully captured, another source of fresh water can be provided in these areas."
Shahrokian kawm yuav ua li cas Namib Desert beetles ntes pos huab kom muaj sia nyob. Nws thiab nws cov neeg koom tes tau ua kom pom cov lim dej aerosol rau huab cua ntes ntawm 74th Lub Rooj Sib Tham Txhua Xyoo ntawm APS hydrodynamic department.
Capturing fog has a lot in common with stopping droplets carrying viruses. "Over the past year, the spread of coronavirus in the air has made the public aware of the less intuitive physics of aerosols," shahrokhian said.
Raws li kev tshawb fawb yav dhau los, cov kws tshawb fawb tau tshawb xyuas cov dej ntws thiab cov yam ntxwv hydrodynamic uas tso cai rau cov kab suab puam sau cov dej ntau heev. Beetles siv los cia siab rau huab cua los ntawm cov nroj tsuag, thiab ntau lab xyoo ntawm kev hloov pauv hloov kho lawv lub cev kom ntes thiab lim huab los ntawm lawv tus kheej.
Ntawm qhov tod tes, qhov ncauj qhov ntswg siv fibers los ntes aerosols. Ib pab neeg ntawm cov kws tshawb fawb Fab Kis tsis cuam tshuam tau siv ntau xyoo hauv - nkag siab tob npaum li cas cov ntaub ntim cov tee dej thiab cov ntsiab cai no tuaj yeem tsim cov lim dej zoo dua li cas.
"We are all familiar with using textiles to collect aerosols because we use fiber masks to stop droplets. We emit a breath or speak. This principle also applies to many other situations, including fresh collected water from fog, but many basic problems still exist," said Camille Duprat, a scientist at ladhyx and É Cole Polytechnique.
Duprat thiab nws pab neeg tau sim ib qho qauv rau kev ntes aerosol hauv chav kuaj. Tom qab ntawd lawv tau teeb tsa lub tshuab luam ntawv loj loj hauv huab cua ua haujlwm.
Raws li cov txiaj ntsig no, cov kws tshawb fawb tau thov ib qho kev tsim tshiab huab cua lim tsim, uas siv cov txheej txheem nylon mesh kom ntes tau huab cua ntau li ntau tau. Lawv hais tias tsim kom muaj txiaj ntsig yuav tsum ua haujlwm nyob rau hauv ib puag ncig nyuaj.
