Yave nguva yekuzvidzivirira kubva pakurumwa netumbuyu

Kurumwa neumhutu kunorwarisa vanhu vanosvika mamirioni mazana matatu nemakumi mashanu gore rega rega, uye huwandu hwezvipembenene zvinotakura zvirwere huri kuwedzera nekushanduka kwemamiriro ekunze. Asi ongororo ichangoburwa yakaratidza kuti kushandisa musanganiswa we cellulose inongoitika sechikamu chayo chikuru kunogona kutungamira kudzikiswa kwe350% mukudyisa umhutu paganda remunhu, maererano neNew Atlas, ichitaura nezvePNAS Nexus magazini.

Cellulose inowanikwa zvakachipa uye muhuwandu kubva kumarara kubva kuindasitiri yehuni, pamwe nekubva kune chikafu chepamba uye marara emapepa. Kana yakarapwa ne sulfuric acid, iyo cellulose inoungana kuita CNC nanocrystals, ichigadzira yakasimba, inoonekera inodzivirira firimu.

pfapfaidzo kana gel

Masayendisiti akawana kuti mushure mekusanganisa nanocrystals nemvura uye glycerin shoma, inogona kupfapfaidzwa semhute kana gel inogoverwa pamusoro peganda remunhu, zvichitadzisa kugona kweumhutu kuruma kudhonza ropa.

Umhutu hadzi dzechikadzi dzinoda ropa kubva kuvanhu kana mhuka kuti dziburitse mazai, saka kudzikisira kwakakosha kwechikafu, kunyanya munzvimbo dzine vanhu vakawanda, kunogona kuita zvakanaka pakudzora huwandu hwezvipembenene.

Zvishandiso zvakawanda

Iko kusanganiswa kweCNC nanocrystals, iyo inoshanda sechipingamupinyi chinoshanda, yakagadziridzwa mumhando dzakasiyana-siyana dzekushandisa zvakatipoteredza, zvakadai sekudzivirira inzwi, kubvisa dhayi kubva mumucheka, kugadzira mabhanhire akasimba akadai sesuperglue, uye akaomeswa macomposites akadai sefupa.

Zvimwe zvidzidzo zvakaratidza kuti CNC coating zvakare yakadzivirira kupfuura kweammonium hydroxide vapor - inowanzokwezva umhutu - payakaiswa kusefa bepa uye kuratidzwa kune zvipembenene.

Kupokana ne22 mavhairasi ane ngozi

Zvingangodaro kuti kushandiswa kwakakura kwemusanganiswa mutsva kuchabatsira kuderedza kupararira kwemhando dzeumhutu dzakadai seAE. Aegypti, vatakuri veanopfuura makumi maviri nemaviri mavhairasi ane njodzi, anosanganisira dengue, chikungunya, Zika, encephalitis yekuJapan, Rift Valley fever, yellow fever, uye mavhairasi eWest Nile.
