Interest in the biological properties of rubidium and cesium stems from their close physicochemical relationship to potassium. Reference to the Periodic Table shows these elements to be adjacent members of the Group I alkali metal series, which has the order: lithium, sodium, potassium, rubidium, cesium. In terms of their chemical behavior the elements of this series may be separated into two g...

We report the experimental generation of squeezed light at 852 nm, locked on the Cesium D(2) line. 50% of noise reduction down to 50 kHz has been obtained with a doubly resonant optical parametric oscillator operating below threshold, using a periodically-poled KTP crystal. This light is directly utilizable with Cesium atomic ensembles for quantum networking applications.

Self-treatment of cancer with cesium chloride, despite proven lack of efficacy, continues to produce serious adverse effects. Among these is hypokalemia predisposing to life-threatening arrhythmia. The mechanism of cesium-associated hypokalemia (CAH) has not been described. We report urinary potassium wasting responsive to amiloride therapy in a cancer patient with CAH, and discuss possible mec...

A massive amount of radioactive materials has been released into the environment by the Fukushima Dai-ichi Nuclear Power Plant accident, but its biological impacts have rarely been examined. Here, we have quantitatively evaluated the relationship between the dose of ingested radioactive cesium and mortality and abnormality rates using the pale grass blue butterfly, Zizeeria maha. When larvae fr...

After presenting a very brief outline of this flight program, this paper will dwell in more detail on the key challenges that must be met for successful flight. These include the comparison of the frequency of the PARCS cesium clock with Earth-bound cesium clocks using the GPS carrier-phase method, the implementation of the phase modulation scheme needed to minimize the impact of space-station ...

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...

Oxalic acid is an attractive chemical platform potentially available from CO2 due to its established applications and characteristics enabling it serve as a mediator in hydrometallurgy including iron-making. However, method for synthesizing oxalic has yet be established. In the present work, formation of oxalate scaffold during heating cesium carbonate (Cs2CO3) presence H2 reactants was experim...

The reduction of membrane potential in frog sartorius muscle produced by rubidium and cesium ions has been studied over a wide concentration range and compared with depolarization occasioned by potassium ions. The constant field theory of passive flux has been used to predict the potential changes observed. The potential data suggest certain permeability coefficient ratios and these are compare...
