Brus equation emission energy Δ"E" = "hc"/λ, where c is the speed of light). This is useful for calculating the radius of a quantum dot from experimentally determined parameters. The overall equation is "E", "m"*, and "m"* are unique for each nanocrystal composition. For example, with CdSe nanocrystals: Brus equation The Brus equation can be used to describe the emission energy of quantum dot semiconductor nanocrystals (such as CdSe nanocrystals) in terms of the band gap energy "E", Planck's constant "h", the radius of the quantum dot "r", as well as the effective mass of the excited electron "m"* and of the
E=MC² (Mariah Carey album) "I'm That Chick". As the release date drew near, the title was changed to "E=MC²", in reference to Carey's previous album, "The Emancipation of Mimi" (2005). The title signifies "(E) Emancipation (=) of (MC) Mariah Carey (²) to the second power". It is a word play on Albert Einstein's famous mass–energy equivalence formula and has been dubbed as the sequel and improved counterpart to "The Emancipation of Mimi". In his review of the album, Alex Macpherson from "The Guardian" described his thoughts on its title, as well as its meaning: It is worth pondering what the title of Mariah Carey's
