Towards high-valent uranium compounds from metallacyclic uranium(IV) precursors.
Treatment of [NaUN*(C,N)(2)] [N* = N(SiMe(3))(2); C,N = CH(2)SiMe(2)N(SiMe(3))] with I(2) led to the formation of the larger metallacycle [UN*(N{SiMe(3)}SiMe(2)CH(2)CH(2)SiMe(2)N{SiMe(3)})I] resulting from U-C cleavage and C-C coupling. Reaction of [NaUN*(O,N)(2)] [O,N = OC(=CH(2))SiMe(2)N(SiMe(3))] with I(2) afforded the U(V) complex [Na{UN*(O,N)(2)}(2)(μ-I)] which was converted into the monon...
متن کاملCalculations of absorbed dose and energy dependent of small-scale dosimeters for photons beam therapy
In this study, the energy dependency for dosimeters of air ionization chambers, lithium fluoride, silicon and plastic scintillator has been studied using the MCNPX Monte Carlo simulation code and simulated for gamma energy in the range of radiotherapy energy. The simulation results show that the response of each of the dosimeters for gamma photon beams in the energy range of 0.2 to 20 MeV varie...
متن کاملMIXED VALENT SEMICONDUCTORS : SmB6
An overview is given of the experimental and theoretical evidence that SmB, is a homogeneously mixed valent semiconductor. It is emphasized that the experimental transport properties imply that the Fermi surface is either extremely small or non-existent, and that rather general theoretical considerations support the possibility of a gap at the Fermi level.
متن کاملAnomalous pseudocapacitive behavior of a nanostructured, mixed-valent manganese oxide film for electrical energy storage.
While pseudocapacitors represent a promising option for electrical energy storage, the performance of the existing ones must be dramatically enhanced to meet today's ever-increasing demands for many emerging applications. Here we report a nanostructured, mixed-valent manganese oxide film that exhibits anomalously high specific capacitance (∼2530 F/g of manganese oxide, measured at 0.61 A/g in a...
متن کاملapplication of small-scale experimental models for thermal comfort assessment of sustainable building materials
accumulation of unmanaged industrial solid waste, especially in developing countries has resulted in an increased environmental concern. in view of utilization of industrial solid waste the recycled paper mill waste (rpmw) – cement composite bricks were designed and developed. in order to investigate the environmental performance of sustainable construction materials two small scale model house...
