The fine-grained data on individual households’ energy utilization collected by smart meters can help infer number of occupants, sleeping patterns, and so on. Beyond confidentiality concerns, integrity and availability are also very important. The automated nature of the smart grid, where supply is...
It is a silvery-grey metal and belongs to the actinide series of the periodic table. Uranium is weakly radioactive, the reason being the instability of all its isotopes.Uranium-238 (146 neutrons) and Uranium-235 (143 neutrons) are its most common isotopes. Uranium's mass number is ...
despite the sustained nature of An-L multiple bond chemistry, terminal actinide-nitrides remain rare, with only two classes of isolable terminal uranium-nitride reported. In 2012, the Liddle group reported [UV(N)(TrenTIPS)][Na(12C4)2] (TrenTIPS = N(CH2CH2NSiPri3)3, 12C4 = 12...
