That is possible , they say , because methyl bromide is cheaper , easier and faster to deploy than chlorine dioxide , the chemical used to rid post offices and the contaminated offices of U.S. Sen. Tom Daschle , D-N.D ., of anthrax . Products of the reaction are iron , titanium dioxide , and water ; oxygen is then extracted from the product water by electrolysis . In addition , Drew Industrial is the leader in chlorine dioxide technology for industrial water service programs utilizing state-of-the-art GENEROXTM chlorine dioxide generators . Wong and collaborators Yonghao Xiu , Lingbo Zhu and Dennis Hess have developed a lotus surface able to withstand ultraviolet radiation using a combination of silicone , fluorocarbons , and inorganics such as titanium dioxide and silicon dioxide . The industry has been using silicon dioxide ( SiO2 ) to build transistor gate dielectrics . When the photoresist is dissolved , there remains a pattern of raised silicon dioxide on the surface . The effectiveness of conventional ( chlorination ) and alternative ( chlorine dioxide , ozonation and ultra violet [ UV ] irradiation ) disinfection procedures for inactivation of Cryptosporidium has been the focus of much research due to the recalcitrant nature of waterborne oocysts to disinfectants . Two are doing well in price and volume : silver and titanium dioxide , a mineral . Additionally , titanium dioxide TiO2 , is a white pigment that is used more and more in paints as lead paint is discontinued due to health considerations . Tokyo , JapanAbstract : The benefits and costs of past nitrogen dioxide ( NO 2 ) control policies were calculated for Tokyo , Japan , using environmental , economic , political , demographic , and medical data from 1973 to 1994 . Silicon and oxygen , the two most common chemical elements in the Earth 's crust , combine as silicon dioxide to form the mineral quartz . " High-k " materials , such as hafnium dioxide ( HfO2 ) , zirconium dioxide ( ZrO2 ) and titanium dioxide ( TiO2 ) inherently have a dielectric constant or " k " above 3.9 , the " k " of silicon dioxide . Also , Scheffrahn said , methyl bromide wo n't corrode or damage electronics and other office equipment as the more-corrosive chlorine dioxide does . Advise patients who have had a significant exposure to nitrogen dioxide to avoid other pulmonary toxins . There are many other " ride along " opportunities like aluminum and caustic soda or paper and titanium dioxide . The debate ping-pongs between a " materials " camp , which favors introducing new materials to planar transistors , and " structural " proponents who advocate moving quickly to double-gated vertical transistors , initially with silicon dioxide in the gate stack . To prevent this , we could add chlorine dioxide ( ClO2 ) to the water , as it is an effective biocide in very low concentrations . Nitrogen dioxide is also a gas without color and odor . Nitric oxide and nitrogen dioxide are nonflammable liquids or gases ; however , they will accelerate the burning of combustible materials .
