Nanomaterials zitha kufotokozedwa ngati zida zomwe zili ndi, osachepera, gawo limodzi lakunja loyeza 1-100nm.Tanthauzo loperekedwa ndi European Commission likuti kukula kwa tinthu ting'onoting'ono pafupifupi theka la tinthu tating'onoting'ono togawa kukula kwa manambala kuyenera kuyeza 100nm kapena pansipa.
Nanomatadium imatha kuchitika mwachilengedwe, kupangidwa ngati zinthu zomwe zimayatsidwa ndi kuyaka, kapena kupangidwa mwadala kudzera muuinjiniya kuti agwire ntchito yapadera.Zidazi zimatha kukhala ndi mawonekedwe osiyanasiyana akuthupi ndi mankhwala kwa anzawo amitundu yambiri.
Kodi Nanomatadium amagwiritsidwa ntchito bwanji?
Chifukwa cha kuthekera kopanga zidazo mwanjira inayake kuti zigwire ntchito inayake, kugwiritsa ntchito ma nanomatadium kumadutsa m'mafakitale osiyanasiyana, kuyambira pazaumoyo ndi zodzoladzola mpaka kuteteza chilengedwe komanso kuyeretsa mpweya.
Gawo lazaumoyo, mwachitsanzo, limagwiritsa ntchito ma nanomatadium m'njira zosiyanasiyana, ntchito imodzi yayikulu ndikubweretsa mankhwala.Chitsanzo chimodzi cha njirayi ndi momwe ma nanoparticles akupangidwira kuti athandize kunyamula mankhwala a chemotherapy mwachindunji ku zophuka za khansa, komanso kupereka mankhwala kumadera a mitsempha yomwe yawonongeka kuti athe kulimbana ndi matenda a mtima.Mpweya wa carbon nanotubes ukupangidwanso kuti ugwiritsidwe ntchito m'njira monga kuwonjezera ma antibodies ku nanotubes kuti apange masensa a mabakiteriya.
M'mlengalenga, ma nanotubes a carbon angagwiritsidwe ntchito posintha mapiko a ndege.Ma nanotubes amagwiritsidwa ntchito mu mawonekedwe ophatikizika kuti apindike poyankha kugwiritsa ntchito mphamvu yamagetsi.
Kwina konse, njira zotetezera zachilengedwe zimagwiritsanso ntchito ma nanomatadium - pankhaniyi, nanowires.Mapulogalamu akupangidwa kuti agwiritse ntchito ma nanowires - zinc oxide nanowires- m'maselo osinthika a dzuwa komanso kuti azitha kuchitapo kanthu pochiritsa madzi oipitsidwa.
Zitsanzo za Nanomaterials ndi Makampani omwe amagwiritsidwa ntchito
Kugwiritsiridwa ntchito kwa nanomatadium kumakhala kofala m'mafakitale osiyanasiyana ndi zinthu za ogula.
M'makampani odzola zodzoladzola, mineral nanoparticles -monga titanium oxide - amagwiritsidwa ntchito poteteza dzuwa, chifukwa cha kusakhazikika komwe kumatetezedwa ndi mankhwala a UV kwa nthawi yayitali.Monga momwe zinthu zambiri zimakhalira, titaniyamu oxide nanoparticles amatha kupereka chitetezo chokwanira cha UV komanso kukhala ndi mwayi wochotsa kuyera kosawoneka bwino komwe kumalumikizidwa ndi zoteteza ku dzuwa mu mawonekedwe awo a nano.
Makampani amasewera akhala akupanga mileme ya baseball yomwe idapangidwa ndi ma carbon nanotubes, zomwe zimapangitsa kuti milemeyi ikhale yopepuka motero imawongolera magwiridwe awo.Kugwiritsiridwa ntchito kwina kwa ma nanomatadium mumsikawu kungadziwike pogwiritsira ntchito antimicrobial nanotechnology muzinthu monga matawulo ndi mateti omwe amagwiritsidwa ntchito ndi ochita masewera, pofuna kupewa matenda obwera chifukwa cha mabakiteriya.
Nanomaterials adapangidwanso kuti azigwiritsidwa ntchito pankhondo.Chitsanzo chimodzi ndikugwiritsa ntchito ma nanoparticles a pigment omwe amagwiritsidwa ntchito popanga mawonekedwe abwinoko obisala, kudzera mu jekeseni wa tinthu tating'onoting'ono mu yunifolomu ya asitikali.Kuphatikiza apo, asitikali apanga makina opanga ma sensor pogwiritsa ntchito ma nanomatadium, monga titanium dioxide, omwe amatha kuzindikira ma biological agents.
Kugwiritsa ntchito nano-titanium dioxide kumafikiranso kugwiritsa ntchito zokutira kuti apange malo odziyeretsa okha, monga mipando yamaluwa apulasitiki.Filimu yosindikizidwa yamadzi imapangidwa pa zokutira, ndipo dothi lililonse limasungunuka mufilimuyo, pambuyo pake kusamba kotsatira kudzachotsa dothi ndikuyeretsa kwambiri mipando.
Ubwino wa Nanomatadium
Makhalidwe a nanomatadium, makamaka kukula kwake, amapereka maubwino osiyanasiyana poyerekeza ndi kuchuluka kwa zinthuzo, ndipo kusinthasintha kwawo malinga ndi kuthekera kowasintha kuti akwaniritse zofunikira zina kumawonjezera phindu lawo.Ubwino wowonjezera ndi porosity yawo yayikulu, yomwe imawonjezeranso kufunika kwa ntchito yawo m'mafakitale ambiri.
M'gawo lamagetsi, kugwiritsa ntchito nanomaterials ndi kopindulitsa chifukwa amatha kupanga njira zomwe zilipo zopangira mphamvu - monga ma solar panels - ogwira ntchito komanso okwera mtengo, komanso kutsegula njira zatsopano zogwiritsira ntchito mphamvu ndi kusunga mphamvu. .
Nanomatadium imayikidwanso kuti iwonetse maubwino angapo mumakampani amagetsi ndi makompyuta.Kugwiritsa ntchito kwawo kudzalola kuwonjezeka kwa kulondola kwa zomangamanga zamagetsi zamagetsi pamlingo wa atomiki, kuthandizira pakupanga zinthu zambiri zamagetsi.
Chiŵerengero chachikulu kwambiri chapamwamba-to-volume cha nanomatadium chimakhala chothandiza kwambiri pakugwiritsa ntchito pachipatala, chomwe chimalola kugwirizana kwa maselo ndi zosakaniza zogwira ntchito.Izi zimabweretsa phindu lodziwikiratu la kuwonjezeka kwa mwayi wolimbana bwino ndi matenda osiyanasiyana.
