Imirasire ya Ultraviolet ni kimwe mu bintu by'ingenzi bigize urumuri rw'izuba, kandi uburebure bwabyo burashobora kugabanywamo imirongo itatu. Muri byo, UVC ni umuhengeri mugufi, winjizwa kandi ugahagarikwa nigice cya ozone, ntishobora kugera ku butaka, kandi nta ngaruka mbi igira ku mubiri w'umuntu. Kubwibyo, UVA na UVB mumirasire ya ultraviolet nitsinda nyamukuru ryumuraba wangiza uruhu rwabantu.

Hongwu Nanodioxyde ya titanium (TiO2) nanopowderifite uduce duto duto, ibikorwa byinshi, ibintu byangiritse kandi bifotora cyane. Ntishobora kwerekana gusa no gukwirakwiza imirasire ya ultraviolet gusa, ahubwo irashobora no kuyikuramo, bityo ikagira imbaraga zikomeye zo guhagarika imirasire ya UV. Nibyiringiro byumubiri UV-ikingira ikingira hamwe nibikorwa byiza.

Ubushobozi bwo kurwanya UV bwa nano TiO2 bufitanye isano nubunini bwabwo. Iyo ingano yubunini bwa titanium dioxyde nanoparticle ari 00300nm, imirasire ya ultraviolet ifite uburebure buri hagati ya 190 na 400nm iragaragazwa cyane kandi ikanyanyagiza; iyo ingano yubunini bwa titania nanopowder ari <200nm, kurwanya UV bigaragarira cyane kandi bigatatana. Uburyo bwo kurinda izuba imirasire ya ultraviolet mu turere twinshi two hagati n’umuhengeri muremure biroroshye gutwikira, kandi ubushobozi bwo kurinda izuba ni ntege; iyo ingano yubunini bwa poro ya TiO2 nano iri hagati ya 30 na 100nm, kwinjiza imirasire ya ultraviolet mukarere k’umuhengeri wo hagati byiyongera cyane, kandi ingaruka zo gukingira imirasire ya ultraviolet ninziza. Nibyiza, uburyo bwo kurinda izuba ni ugukuramo imirasire ya ultraviolet.

Muri make,dioxyde ya titanium nanoifite uburyo butandukanye bwo kurinda izuba kuburebure butandukanye bwimirasire ya ultraviolet. Iyo uburebure bwimirasire ya ultraviolet ari ndende, imikorere yo gukingira nano titanium dioxide TiO2 biterwa nubushobozi bwayo bwo gusasa; iyo uburebure bwimirasire ya ultraviolet ari ngufi, imikorere yayo yo gukingira biterwa nubushobozi bwayo. Nukuvuga ko ubushobozi bwa nano titanium oxyde yo gukingira imirasire ya ultraviolet bigenwa nubushobozi bwayo bwo kwinjiza no gukwirakwiza. Ingano ntoya yingirakamaro, niko imbaraga za UV zo kwinjiza za nano titanium dioxyde de dioxyde.

Ubushakashatsi bwerekana ko Hongwu Nano ya nano rutile titanium dioxide TiO2 ifite UV ikingira neza kuruta nano anatase TiO2. Nano TiO2 ifite amahirwe yo gukoreshwa muburyo bwo kurwanya UV kurangiza imyenda no mu mwenda urwanya ultraviolet ku kirahure.
