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) (indicating "generally positive reviews") on the website Metacritic, which averages professional reviews into a numerical score. Stephen Thomas Erlewine, senior editor of Allmusic, rated the album three out of five stars, and wrote "it's misleading to judge Mariah based on her new record of possessing the most number one singles, as she's not about longevity, she's about being permanently transient, a characteristic 'E=MC²' captures all too well." "Billboard"s Gary Trust felt that on the album, Carey was in "pristine form", stating, "She's proclaimed emancipation before, but Mariah Carey's never sounded as free as she does on her 10th album.
