Ob peb hnub dhau los, ib phau ntawv xov xwm tau tshaj tawm tias pawg tshawb fawb ntawm Xib Fwb Kang Junyong thiab Associate Professor Yin Jun ntawm Xiamen University tau tsim lub zog siab (3.2 W) thiab cov teeb pom kev zoo sib xws ntawm 275nm nitride LED raws li lub teeb ultraviolet. Kev nqus cov yam ntxwv ntawm cov khoom siv caj ces thiab cov protein hauv cov kab mob pathogenic, uas tuaj yeem tua tus kabmob tshiab, tus kab mob khaub thuas H1N1 thiab Staphylococcus aureus hauv 1 thib ob.
Fig.1 High-power tob ultraviolet planar teeb qhov chaw. (a) Nitride solid-state light source module; (b) Lub wavelength ntawm lub teeb qhov chaw module thiab cov yam ntxwv ntawm ultraviolet absorption ntawm cov kab mob; (c) Cov nyhuv bactericidal ntawm lub teeb ci.
Nws tau tshaj tawm tias pab pawg tshawb fawb tau siv lub teeb pom kev zoo hauv lub xeev los tshawb txog qhov cuam tshuam ntawm cov yam tsis paub xws li cov kab mob sib txawv thiab ib puag ncig kub ntawm cov tshuaj tua kab mob ntawm DUV. Cov kev tshawb fawb tau pom tias qhov chaw khov (piv txwv li, rho tawm 50 degrees Celsius) yuav tsum tau siv ntau dua ntawm UV hluav taws xob kom ua tiav tib qhov kev tuag ntawm chav tsev kub. Thawj thawj zaug, pab pawg tshawb fawb tau tsim kom muaj kev so loj tsis zoo U qauv ntawm biophotoelectric nyhuv los qhia txog qhov cuam tshuam ntawm qhov kub thiab txias.
Pab neeg no tau sau tseg tias thaum qhov kub thiab txias, muaj qhov tshwm sim ntau dua tias cov hluav taws xob zoo siab los ntawm DUV yuav rov qab los ntawm cov tshuaj genetic molecule rov qab mus rau qhov chaw pib photoionization. Nws yog ib qho tsim nyog sau cia tias vim yog cov yam ntxwv ntawm cov khoom siv caj ces thiab cov protein, Omicron xav tau ntau dua DUV koob tshuaj kom ua tiav cov nyhuv tua tib yam li lwm hom.
Raws li cov ntaub ntawv ntsuas tshuaj tua kab mob, pab pawg tshawb fawb tau tsim cov tshuaj tiv thaiv kev sib raug zoo ntawm cov koob tshuaj DUV sib raug zoo thiab cov nyhuv tua, muab lub hauv paus kev tshawb fawb rau cov kws kho mob kom tau txais cov koob tshuaj tiv thaiv ultraviolet sai uas tuaj yeem tua tus kabmob tshiab ntawm qhov sib txawv. kub. Qhov no muaj lub luag haujlwm qhia txog yuav ua li cas DUV tuaj yeem siv los tiv thaiv kev kis tus kabmob tshiab tus kabmob pneumonia, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias (xws li, khoom noj khoom haus txias saw logistics thiab lub caij ntuj no qhib huab cua puag ncig).
Pab neeg no tau taw qhia tias qhov kev tshawb pom ntawm txoj kev tshawb fawb no tseem ceeb heev rau tib neeg lub neej los siv cov duab sib sib zog nqus ultraviolet photons rau kev tua kab mob hauv cov mob khaub thuas.
