DNA typing was first used in Great Britain for law enforcement purposes in the mid- 1980s. It wasn’t employed in the United States until 1987. DNA profiling has changed forensic science. DNA technology has given police and the courts a means of identifying the suspects of rapes and murders. Today‚ the Federal Bureau of Investigation performs the bulk of the forensic DNA typing for local and state law enforcement agencies. In criminal investigations‚ DNA from samples of hair‚ bodily fluids or skin

chemical reaction. Such a reaction involves two chemicals reacting with one another to form a high-energy intermediate‚ breaking down releasing energy as photons of light. Luminol‚the main ingredient in chemiluminescence. When mixed with the appropriate oxidizing agent luminol creates a blue glow. The chemical formula for luminol is C8H7N3O2. Scientists are interested in chemiluminescence because it allows them to know how fireflies and other species produce a glowing light naturally. Also one could

of the most important key terms in the scientist project is chemiluminescence which means ‚” a very efficient process that converts energy to light” (Keren Perles 2012). This project is very dangerous because “23% of all cases of exposure to chemiluminescent products reported to an urban poison control center” ( Robert L. Hoffman 2002). It can be a very dangerous project if the scientist doesn’t know what he is doing. Glow sticks have also been a great project inducer in the marine field. Glow sticks

TiO2 in Road Pavement Reduces NOx Abstract: The objective of this study is to test the hypothesis that titanium dioxide (TiO2) can function as a photo catalytic compound when used in the preparation of warm-mix asphalt (WMA). The proposed asphalt mixture would combine the benefits of WMA such as reduced energy consumption and emission during production with the photo catalytic properties of TiO2 to trap and degrade organic and inorganic particles in the air. Two application methods were evaluated

It was derived from the wood of two tree species‚ Pterocarpus indicus andEysenhardtia polystachya.[2][3][4][5] The chemical compound responsible for this fluorescence is matlaline‚ which is the oxidation product of one of the flavonoids found in this wood.[2] In 1819 Edward D. Clarke[6] and in 1822 René Just Haüy[7] described fluorescence in fluorites‚ Sir David Brewster described

it helps them in an investigation. Ok so finding blood stains can be quite easy if shown in plain site ‚but what if the it was cleaned up? Scientist came up with a way of using a chemical mixture to show hidden blood stains even when clean called Luminol or (C8H7N3O2) which reacts with iron found in hemoglobin. Porous
