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) Building was lit up in Carey's motif colors—lavender, pink, and white — in celebration of her achievements in the world of music. On the Canadian Albums Chart, during the week dated May 3, 2008, "E=MC²" debuted at number one, with first-week sales of 19,000 copies. It became her first number one album in Canada since before 1999, as "Rainbow" and "The Emancipation of Mimi" both opened at number two. The album spent seven weeks within the album's chart, and was eventually certified Platinum by the Canadian Recording Industry Association (CRIA), denoting shipments of 100,000 units. "E=MC²" entered the Australian Albums
