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
What Does the Bee Do? What Does the Bee Do? "What Does the Bee Do?" is the fourth episode of the second season of the HBO television series "Boardwalk Empire", and 16th episode overall. First aired on October 16, 2011, it was written by executive story editor Steve Kornacki and directed by Ed Bianchi. Nucky looks to Rothstein for a port to receive alcohol, since the Coast Guard is blockading Atlantic City. Rothstein instructs Lansky and Luciano to oversee the Philadelphia delivery. Nucky also sends Owen Sleater to bomb Doyle's still. Margaret asks for 'money for the children' from Nucky, which she proceeds to hide
