Russia tsim cov thev naus laus zis tshiab los txhim kho cov kab mob tua kab mob ntawm titanium alloys kom ceev qhov txhab rov qab

Lavxias National Research University of Technology thiab lwm cov kws tshawb fawb Lavxias tau tsim cov thev naus laus zis tshiab uas tuaj yeem ua cov titanium alloy, ib qho ntawm cov ntaub ntawv tseem ceeb rau kev phais kev phais, tsim cov tshuaj tua kab mob.uas tau tshaj tawm los ntawm Technology Daily . Cov kws tshawb fawb tau hais tias kev cog qoob loo ua tiav los ntawm txoj kev tshiab yuav ua rau sai sai thiab txhawb nqa qhov txhab. Kuj tseem muaj cov txiaj ntsig kev tshawb fawb tau tshaj tawm hauv phau ntawv xov xwm ntawm "Colloid thiab Surface B: Biological Interface".

Cov neeg kho tshuab kev ua tau zoo thiab kev muaj peev xwm rov qab los rau cov pob txha puas, uas yuav txo qis nrog lub hnub nyoog, thiab qhov kev puas tsuaj no yuav xav tau kev kho mob mus ntev. Kev siv cov khoom cog los ntawm cov hlau tsis hloov pauv thiab cov alloys yuav ua rau muaj teeb meem, uas tej zaum yuav tsum tau ua haujlwm phais thib ob tom qab. Cov ntaub ntawv uas tuaj yeem cuam tshuam cov kev ua ntawm cov kab mob tuaj yeem pab txhim kho kev cog qoob loo hauv lub cev kom nyab xeeb thiab txhim khu kev qha. Yog li, cov kws tshawb fawb Lavxias tau tsim ib txoj hauv kev los txau cov tshuaj tua kab mob ntawm Ti-Zr-Nb, uas yog ib qho ntawm cov titanium alloys.

Kev ntsuam xyuas pom tau tias kev kho mob nrog txoj kev tshiab tuaj yeem cuam tshuam kev loj hlob ntawm E. coli ntawm qhov chaw cog. Ntawm qhov nyiaj tsawg ntawm cov nyiaj tso tawm (kwv yees li 0.037 mg / L), nws muaj kev nyab xeeb rau lub cev thiab ua tiav cov txiaj ntsig tseem ceeb ntawm cov kab mob. Cov kws tshawb fawb tau hais tias "kev tawm tsam" tawm tsam cov kab mob yog ua los ntawm cov nyiaj ions. Cov kws tshawb fawb tau tsim cov tshuaj nanoparticles uas tso tawm rau hauv cov tshuaj cawv complex, uas ua rau nws tsuas yog 10 nanometers loj. Yuav kom tau txais txiaj ntsig ntawm qhov no, nyiaj yog tso rau hauv qhov pores ntawm cov khoom, thiab qhov tob ze li ntawm 60 nanometers, uas txhim kho cov nyhuv durability thiab cov nyhuv antibacterial rial rau txheej.
