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) need to look no further than its title. Long live the Diva." Caryn Ganz from "Rolling Stone" questioned why she limited her vocal abilities throughout the record, "nearly every song confines Carey to four-note verses, offering little room for her glorious range." Journalist Eric Henderson, writing for "Slant Magazine", graded the album three out of five stars, and concluding with, "Such are the rewards of an album like 'E=MC²', in which one does reach a solution, but not before Mariah bends over backward to show her work." The album finished in the top-ten of several "best of 2008" lists, ending
