Metal-silicate Partitioning of Cesium – Implications for Planetary Core Formation
Introduction: We present here preliminary results on partitioning of cesium between metal and silicate at high pressure and temperature. The purpose of these experiments is to develop a data set for the metalsilicate partitioning of cesium, a lithophile element with apparent mantle depletion, to determine whether, and under what conditions, cesium may take on more siderophile behavior. These da...
متن کاملFormation of Cesium Peroxide and Cesium Superoxide on InP Photocathode Activated by Cesium and Oxygen
Activation of p type III-V semiconductors with Cesium and Oxygen has been widely used to prepare Negative Electron Affinity (NEA) photocathodes. However, the nature of the chemical species on the surface after the activation is not well-understood. In this study, InP NEA photocathodes activated with Cesium and Oxygen are studied using Synchrotron Radiation Photoelectron Spectroscopy, also calle...
متن کاملPositively and Negatively Charged Cesium and (C60)mCsn Cluster Ions
We report on the formation and ionization of cesium and C60Cs clusters in superfluid helium nanodroplets. Size distributions of positively and negatively charged (C60) m Cs n± ions have been measured for m ≤ 7, n ≤ 12. Reproducible intensity anomalies are observed in high-resolution mass spectra. For both charge states, (C60) m Cs3± and (C60) m Cs5± are particularly abundant, with little depend...
متن کاملTrends in Effective Diffusion Coefficients for Ion-Exchange Strengthening of Soda-Lime-Silicate Glasses
Monovalent cations enable efficient ion-exchange processes due to their high mobility in silicate glasses. Numerous properties can be modified in this way, e.g., mechanical, optical, electrical, or chemical performance. In particular, alkali cation exchange has received significant attention, primarily with respect to introducing compressive stress into the surface region of a glass, which incr...
متن کاملCesium toxicity in Arabidopsis.
Cesium (Cs) is chemically similar to potassium (K). However, although K is an essential element, Cs is toxic to plants. Two contrasting hypotheses to explain Cs toxicity have been proposed: (1) extracellular Cs+ prevents K+ uptake and, thereby, induces K starvation; and (2) intracellular Cs+ interacts with vital K(+)-binding sites in proteins, either competitively or noncompetitively, impairing...
