Two-dimensional (2-D) semiconductors are promising for quantum computing and future electronics. Now, researchers can convert metallic gold into semiconductor and customize the material atom-by-atom on boron nitride nanotubes. Gold is a conductive material already widely used as interconnects in electronic devices. As electronics have gotten smaller and more powerful, the semiconducting materials involved have also shrunk. However, computers have gotten about as small as they can with existing designs—to break the barrier, researchers dive into the physics underlying quantum computing and the unusual behaviors of gold in quantum mechanics. Researchers can convert gold into semiconducting quantum dots made of a single layer of atoms. Their energy gap, or bandgap, is formed by the quantum confinement—a quantum effect when materials behave like atoms as their sizes get so small approaching the molecular scale. These 2-D gold quantum dots can be used for electronics with a bandgap that is

WOW This really is fucked up! Five Atlanta gang members were convicted this week of raping and killing a man that was a former police informant. Prosecutors are calling it “the most brutal murder” in the city’s recent history. The men all purported members of the Gangster Disciples street gang murdered Christopher Dean, 33, in October 2016 after they discovered that he was once a police witness in California. Christopher Lockett, 30, had invited the victim to the home of brothers Xavier Gibson, 23, and Orlando Gibson, 30. The victim was told that he could buy drugs at the location, the Fulton County District Attorney’s Office said in a statement. But instead, Dean was brutally beaten with a two-by-four and a crowbar and sodomized with a handle-like object and seminal fluid was discovered in his rectal cavity, prosecutors said. The gang members Lockett, Xavier Gibson, Quatez Clark, 21, Joshua Rooks, 27, and Jasper Green, 27, were convicted Monday of murder, participation in criminal str
