Trinitrotoluene ( /ˌtraɪnaɪtrɵˈtɒljʉ.iːn/; TNT), or more specifically, 2,4,6-trinitrotoluene, is a chemical compound with the formula C6H2(NO2)3CH3. This yellow-colored solid is sometimes used as a reagent in chemical synthesis, but it is best known as a useful explosive material with convenient handling properties. The explosive yield of TNT is considered to be the standard measure of strength of bombs and other explosives. In chemistry, TNT is used to generate charge transfer salts.
In industry, TNT is produced in a three-step process. First, toluene is nitrated with a mixture of sulfuric and nitric acid to produce mono-nitrotoluene or MNT. The MNT is separated and then renitrated to dinitrotoluene or DNT. In the final step, the DNT is nitrated to trinitrotoluene or TNT using an anhydrous mixture of nitric acid and oleum. Nitric acid is consumed by the manufacturing process, but the diluted sulfuric acid can be reconcentrated and reused. Subsequent to nitration, TNT is stabilized by a process called sulphitation, where the crude TNT is treated with aqueous sodium sulfite solution in order to remove less stable isomers of TNT and other undesired reaction products.

Energy is a Taiwanese pop rock boy band formed in 2002. The original band consisted of five members, namely Milk, Ady, Toro, Penny and Joe. Toro and Milk left the band in 2003 and 2005 respectively. Xiao Gang joined the band in mid 2007. The band is now officially disbanded since 2009.
Five-member Energy had a distinctive Hip-Hop sound, which is sometimes mixed with electric guitars, like in their breakout hit "Let Go" (放手). Energy incorporates dance cheography to perform their up-tempo tracks, often compared to dance performances of Korean boy bands. Energy also has slow ballads like "Love Me for Another Day" (多爱我一天) and "One Day" (某年某月某一天). Energy's popularity grew at a time where other mainstream Taiwanese boy bands like 5566 and K One emerged. Energy had a fan base of mostly goth fans and people who liked Japanese rock, but also attracted a mainstream audience.
Energy's first studio album Energy! Come On! was released within the same year of the band's formation. The cover of Korean boyband Shinhwa's "Come On" had a huge publicity in Chinese pop culture, and caused controversy between Shinhwa's and Energy's fans. Shinhwa fans claimed that Energy copied Shinhwa's dance moves and
