and nitrogen oxides [19].A photocatalytic cement that uses titanium dioxide as a primary component was included  in Time's Top 50 Inventions of 2008 [20].For wastewater remediation[සංස්කරණය]TiO2 offers great potential as an industrial technology for detoxification or remediation of wastewater due to several factors.The process occurs under ambient conditions very slowly, direct UV light exposure increases the rate of reaction.The formation of photocyclized intermediate products, unlike direct photolysis techniques, is avoided.Oxidation of the substrates to CO2 is complete.The photocatalyst is inexpensive and has a high turnover.TiO2 can be supported on suitable reactor substrates.Other applications[සංස්කරණය]It is also used in resistance-type lambda probes (a type of oxygen sensor).Titanium dioxide is what allows osseointegration between an artificial medical implant and bone.Titanium dioxide in solution or suspension can be used to cleave protein that contains the amino a
