Sekuyisikhathi sokuzivikela ekulunyweni yizinambuzane

Ukulunywa omiyane kugulisa abantu ababalelwa ezigidini ezingu-350 unyaka ngamunye, kanti isibalo sezinambuzane ezithwala izifo sizokhula ngokushintsha kwesimo sezulu. Kodwa ucwaningo lwakamuva lubonise ukuthi ukusebenzisa inhlanganisela ye-cellulose eyenzeka ngokwemvelo njengengxenye yayo eyinhloko kungaholela ekwehleni ngo-80% kokudla omiyane esikhumbeni somuntu, ngokusho kwe-New Atlas, ecaphuna iphephabhuku le-PNAS Nexus.

I-Cellulose itholakala ngenani eliphansi futhi ngobuningi emfucumfucwini evela embonini yokwenza izinkuni, kanye nokudla kwasekhaya kanye nemfucumfucu yamaphepha. Uma iphathwa nge-sulfuric acid, i-cellulose ihlangana ibe ama-nanocrystals e-CNC, idale ifilimu yokuvimbela eqinile, esobala.

fafaza noma ijeli

Ososayensi bathole ukuthi ngemva kokuxuba ama-nanocrystals namanzi nenani elincane le-glycerin, angafuthwa njengenkungu noma ijeli esatshalaliswa ebusweni besikhumba somuntu, okuvimbela omiyane ukuba balume ukuze bakhiphe igazi.

Omiyane besifazane abadala badinga igazi elivela kubantu noma ezilwaneni ukuze bakhiqize amaqanda, ngakho ukuncipha okuphawulekayo komthombo wokudla, ikakhulukazi ezindaweni eziminyene, kungaba nomthelela omuhle ekulawuleni izinambuzane.

Ukusetshenziswa okuningi

Ingxubevange ye-CNC nanocrystals, esebenza njengesithiyo esisebenzayo, iye yathuthukiswa ezinhlobonhlobo zezinhlelo zokusebenza ezinobungani bemvelo, njengokuvala umsindo, ukususwa kodayi ezindwangu, ukwenziwa kwezibophelelo eziqinile ezifana neglue, nezinhlanganisela eziqinile ezifana nethambo.

Olunye ucwaningo lubonise ukuthi ukunamathela kwe-CNC kuvimbele ukudlula komhwamuko we-ammonium hydroxide - into evamile eheha omiyane - lapho isetshenziselwa ukuhlunga iphepha futhi kuvezwe ezinambuzaneni.

Ukumelana nama-virus ayingozi angama-22

Kungenzeka ukuthi ukusetshenziswa kabanzi kwengxube entsha kuzosiza ukunciphisa ukusabalala kwezinhlobo zomiyane njenge-AE. I-Aegypti, abathwali bamagciwane ayingozi angaphezu kwama-22, okuhlanganisa udenga, i-chikungunya, i-Zika, i-encephalitis yaseJapane, i-Rift Valley fever, i-yellow fever, namagciwane ase-West Nile.
