The optical properties of liquid cerium at 632.8 nm

Mechanical properties of cerium and a cerium–5wt% lanthanum alloy by nanoindentation and ultrasonic velocity measurements

“…Zukas et al [2] recommended that, for best results, the final polish during metallographic preparation should be completed in less than 2 min, no more than 2 min should elapse between polishing and etching and photography should be completed in 6-8 min. Even when stored in a vacuum desiccator Sheldon et al [12] found that the surface tarnished within a day. Therefore, Ce must be stored in an air-free environment and contact with water and water-based fluids avoided.…”

In Situ Small-Angle Neutron Scattering Analysis of the Initial Deuteride Formation of Deuterium–Cerium Reactions under a Controlled Gas Flow

“…Because of the high activity of cerium, the surface oxide layer is inevitably formed even when it is stored in a vacuum desiccator . The detection of initial precipitation of hydrides is typically problematic because of both the interference from coating oxides and the high activity of cerium hydrides.…”

Spectroscopic ellipsometry for active nano- and meta-materials

“…SE has been performed in situ for evaluating the dielectric function of metals or metallic compounds as a function of temperature, below and above their melting point [39,49,[71][72][73][74][75][76][77][78][79][80][81][82][83][84]. It has been used early to measure, in the near UV-to-near IR spectral range, the dielectric function of the liquid phase of metals with a low melting point, such as Na, Sn, Hg [71], and later that of Ga in its solid [72] and liquid [72,73] state, that of Bi in its solid [66] and liquid [73,74] state.…”

“…SE-based works have also been devoted to the wetting transitions at the surface of Ga-Bi alloys [73,76], to surface freezing in Ga-based alloys [77], and to wetting and prewetting transitions at the metal-rich K-KCl melt-sapphire interface [78,79]. SE measurements at higher temperatures (up to 1350°C) have also been performed from the visible to the far IR on molten metals [80][81][82][83][84]. Much attention has also been devoted to the SE characterization of the dielectric function of vanadium oxides, VO 2 [85][86][87][88] and V 2 O 3 [88,89], from the near UV to the far IR and at different temperatures, in order get insights into the parameters driving their insulator-to-metal transition occurring at moderate temperature.…”
