removal of cesium from synthetic aqueous solution through adsorption on vermiculite, under batch equilibrium experimental condition at six initial values of ph (3, 4, 6, 9, 11 and 12) and five temperatures (25, 50, 75, 85 and 95 °c) has been investigated. it is necessary to propose a suitable model for a better understanding of the mechanism of cesium adsorption on vermiculite. for this propose...

It has been shown experimentally for the first time that diffusion of cesium n rhenium takes place at irradiation of atoms flux heated up to Т ≤ 1800 K ( ) Re 1010 -C. Analysis of thermal desorption spectra showed that cesium forms two high-temperature phases during adsorption of cesium on graphite monolayer in rhenium heated up to 1800 K. The first, intercalated phase starts filling immediatel...

We analyzed the global transcriptional response of Saccharomyces cerevisiae cells exposed to different concentrations of CsCl in the growth medium and at different times after addition. Early responsive genes were mainly involved in cell wall structure and biosynthesis. About half of the induced genes were previously shown to respond to other alkali metal cations in a Hog1-dependent fashion. We...

During the development of a new method of analyzing crystals by X-rays we discovered that the X-rays characteristic of and excited in the chemical elements in a crystal are reflected by the crystal itself. The reflection takes place both in accordance with the Bragg law: nX = 24 sin 0 and. also in an anomalous fashion. The ionization spectrometer utilized in these investigations and the various...

Zirconia powder was synthesized via a sol gel method and placed in a batch reactor for cesium removal investigation. X-ray analysis and Fourier transform infrared spectroscopy were utilized for the evaluation of the developed adsorbent. The adsorption process has been investigated as a function of pH, contact time and temperature. The adsorption is strongly dependent on the pH of the medium whe...

We combine the Ramsey interferometry protocol, Stern-Gerlach detection scheme, and use of elongated geometry a cloud fully polarized cold cesium atoms to measure selected component magnetic-field gradient along atomic in single shot. In contrast standard method where precession two spatially separated clouds is simultaneously measured extract their phase difference, which proportional gradient,...

From fiscal year 2012 to 2014, we surveyed the concentration of radioactive cesium in 39 wild animal meats obtained from 20 wild boars and 19 deer caught in Chiba prefecture, using a germanium semiconductor detector. Four wild boar meats in the fiscal years 2012 and 2013 exceeded the radioactive cesium limit in general foods (100 Bq/kg), whereas none of the deer meats exceeded the limit. The le...

The accuracy of the National Research Council 2.1 m cesium beam frequency standard has been re-evaluated using the two NRC hydrogen masers as stable comparison standards. At the time of re-evaluation, the various uncertainties gave rise to an error limit of :!:3.8 x 10-12, with a most probable value of :!:1.5 x 10-12 if they were assumed to be random. Mter application of all corrections, the ag...

This experiment demonstrates the formation of nanometer-scale features in a gold substrate using a self-assembled monolayer (SAI{) of nonanethiolate as a resist for a patterned beam of neutral cesium atoms. The mask used to pattern the atomic beam rvas a si l icon nitr ide membrane perforated with nmand plm-scale holes. A dose of ^,3 monolayers of cesium damaged the SAI,I suff iciently to al lo...

The whispering gallery modes ~WGMs! of quartz microspheres are investigated for the purpose of strong coupling between single photons and atoms in cavity quantum electrodynamics ~cavity QED!. Within our current understanding of the loss mechanisms of the WGMs, the saturation photon number n0 and critical atom number N0 cannot be minimized simultaneously, so that an ‘‘optimal’’ sphere size is ta...
