Atomic-Level Understanding toward a High-Capacity and High-Power Silicon Oxide (SiO) Material
, 2016Silicon oxide (SiO) has attracted much attention as a promising anode material for Li-ion batteries. The lithiation of SiO results in the formation of active Li–Si alloy cores embedded in an inactive matrix consisting of Li-silicates (Li2Si2O5, Li6Si2O7,

Journal of Nuclear Energy (1954), 1956
Abstract The paper reviews data on the economics of atomic energy cited in foreign publications. The following questions are examined: The cost structure of electrical energy; the cost of nuclear fuel and auxiliary materials; the capital cost of equipping an atomic-power station, depending on the type of reactor; nuclear fuel cycles and fuel costs ...
