Caesium (or cesium) is the chemical element with the atomic number 55 on the periodic table. Its symbol is Cs. Caesium is an alkali metal. Its melting point is low (28 °C). It is extremely reactive. Because of its high reactivity, it is a dangerous chemical. It may set itself on fire (ignite) in air. It explodes on contact with water. It reacts more violently than the other alkali metals with water. Because of this, caesium is stored in mineral oil.[6] Caesium is a rare element. Since there is little caesium on the Earth, it is rather expensive. The human body does not need caesium. In large amounts, its chemical compounds are mildly poisonous because it is close to potassium, which the body does need. ...

Cesium: Natures premier body alkalizer. Cesium, the most electropositive and least abundant of the five naturally occurring alkali metals, was discovered spectroscopically in 1860. The first cesium metal was produced in 1881. Historically, the most important use for cesium has been in research and development. There are a number of areas of the world where the incidence of cancer is very low. The authors have been able to collect information on the chemical composition of food in these low incidence areas. In every case, the cesium content has been found to be very high. In addition, the diet has been found to be high in the supportive compounds i.e. vitamin C, vitamin A, zinc and selenium. It seems apparent therefore, that the composition of foods and the diet eaten in these areas are similar to the nutritive requirements for the high pH therapy.. Dr. Otto Warburg published a Nobel Prize winning paper over 75 years ago describing the environment of the cancer cell. A normal cell undergoes an ...

ˈsiːziəm/ SEE-zee-əm) is the chemical element with the symbol Cs and atomic number 55. It is a soft, silvery-gold alkali metal with a melting point of 28 °C (82 °F), which makes it one of only five elemental metals that are liquid at (or near) room temperature.[note 2] Caesium is an alkali metal and has physical and chemical properties similar to those of rubidium and potassium. The metal is extremely reactive and pyrophoric, reacting with water even at −116 °C (−177 °F). It is the least electronegative element that has stable isotopes, of which it has only one, caesium-133. Caesium is mined mostly from pollucite, while the radioisotopes, especially caesium-137, are extracted from waste produced by nuclear reactors.. Two German chemists, Robert Bunsen and Gustav Kirchhoff, discovered caesium in 1860 by the newly developed method of flame spectroscopy. The first small-scale applications for caesium have been as a getter in vacuum tubes and in photoelectric cells. In 1967, a specific ...

The particularities of cesium incorporation into synthetic calcium phosphates with either apatite or whitlockite-type structures were investigated using the sorption process from aqueous solution and further heating to 700 °C. The nanoparticles for sorption were prepared by wet precipitation from aqueous solutions at a fixed molar ratio of Ca/P = 1.67 and two different ratios of CO32−/PO43− (0 or 1). The obtained substituted calcium phosphates and corresponding samples after the sorption of cesium from solutions with different molar concentrations (c(Cs+) = 0.05, 0.1 and 0.25 mol L−1) were characterized by powder X-ray diffraction, FTIR spectroscopy, scanning electron microscopy and elemental analysis. Based on the combination of X-ray diffraction and elemental analyses data for the powders after sorption, the cesium incorporated in the apatite- or whitlockite-type structures and its amount increased with its concentration in the initial solution. For sodium-containing calcium phosphate even

Herein we report a robust and easy method for detecting cesium metal ion (Cs+) in partially aqueous solutions using the fluorescence quenching of 2,4-bis[4-(N,N-dihydroxyethylamino)phenyl]squaraine. This squaraine dye was found to be both highly sensitive (low limits of detection) and selective (limited resp

Here, we demonstrate the successful synthesis of brightly emitting colloidal cesium lead halide (CsPbX3, X = Cl, Br, I) nanowires (NWs) with uniform diameters and tunable compositions. By using highly monodisperse CsPbBr3 NWs as templates, the NW composition can be independently controlled through anion-exchange reactions. CsPbX3 alloy NWs with a wide range of alloy compositions can be achieved with well-preserved morphology and crystal structure. The NWs are highly luminescent with photoluminescence quantum yields (PLQY) ranging from 20% to 80%. The bright photoluminescence can be tuned over nearly the entire visible spectrum. The high PLQYs together with charge transport measurements exemplify the efficient alloying of the anionic sublattice in a one-dimensional CsPbX3 system. The wires increased functionality in the form of fast photoresponse rates and the low defect density suggest CsPbX3 NWs as prospective materials for optoelectronic applications.

Semi-conservative replication of DNA was proved by the work of Mathew Meselson and Franklin Stahl (1958). They grew Escherichia coli for many generations in a medium having heavy isotope of nitrogen, in the form of 15NH4Cl, till the bacterial DNA became com-pletely labelled with heavy isotope.. The labelled bacteria were then shifted to fresh medium hav-ing normal or 14N nitrogen. Samples were taken for each generation (one generation takes 20 minutes as E. coli divides in 20 minutes) and the DNA was tested for the heavy isotope of nitrogen through density gradient centrifugation using caesium chloride. Caesium chloride is highly water soluble heavy salt.. When spun in centrifuge at high speed (say 50,000 revolutions per minute) the salt forms a density gradient with heaviest most concentrated region at the bottom and successively less concentrated lighter one towards the surface. When DNA is mixed with caesium chloride it will settle down at a particular height in centrifugation, heavier ...

Co-authors of the paper include Justin Brown, David Butts, Joseph Kinast, and Richard Stoner of Draper Laboratory.. A shift in Time. The team came up with the new atomic timekeeping approach by making several tweaks to the standard method.. The most accurate atomic clocks today use cesium atoms as a reference. Like all atoms, the cesium atom has a signature frequency, or resonance, at which it oscillates. Since the 1960s, one second has been defined as 9,192,631,770 oscillations of a cesium atom between two energy levels. To measure this frequency, fountain clocks toss small clouds of slow-moving cesium atoms a few feet high, much like a pulsed fountain, and measure their oscillations as they pass up, and then down, through a microwave beam.. Instead of a microwave beam, the group chose to probe the atoms oscillations using laser beams, which are easier to control spatially and require less space -- a quality that help in shrinking atomic clock apparatuses. While some atomic clocks also ...

In the case of the reduction of a Ceasium or Rubidium salt (usually the chloride) the reduction of the metal can be effectuated by means of the equilibrium CsCl (s) + Li (l) , === , Cs(g) + LiCl (l) at quite high temperature. But even in those conditions the equilibrium point is still too far to the left to yield much metal. To remediate that, high vacuum is pulled so the Cs vapour distils off. This, following Le Chatelier, pulls the equilibrium to the right and the yield of Cs metal is near quantitative ...

The inward rectifying potassium channels of the ROMK family are present in the distal nephron of the kidney. These channels have two membrane spanning portions, between which lies a hydrophobic domain thought to confer the majority of the conductive properties of the channel. The N- and C-termini are both intracellular. In this paper we have examined the contribution of the N- and C-termini to the pore by examining the interaction of Cs|sup|+|/sup| with the channels. ROMK1 has an additional 19 amino acids on its N-terminus in comparison to ROMK2. The C-terminus of ROMK2 was extended by addition of a streptavidin tag (sfROMK2). Currents were measured following expression in Xenopus oocytes using two-electrode voltage clamp. ROMK1, ROMK2 and sfROMK2 exhibited concentration- and voltage-dependent block of inward currents by extracellular Cs|sup|+|/sup|. The Hill coefficients were not significantly different from one. The mean K|sub|d|/sub| values at 0 mV were 100.6 ± 10.6, 63.1 ± 3.9 and 40.6 ± 9.4,

Each of these changes was made because the precision with which we could make the measurements became greater than the precision with which we could realize, or make use of, the previous definition. Today, we choose definitions based on fundamental physical constants and atomic properties because they provide more stable and universally available standards. They may also generally be measured relatively easily and with high precision. Each change of definition is chosen to maintain unchanged the previous value of the standard, to the accuracy with which it had previously been known.. It is important to note that the effect of each new definition is to set a fixed value for some relevant constant. Thus, the present definition of the second sets the value of the frequency of the caesium transition to be exactly 9,192,631,770 Hertz, and the present definition of the metre sets the speed of light to be exactly 299,792,458 metres per second. The 1793 definition of the metre set the distance from the ...

The Sn Mössbauer data and electronic reflectance spectra of the cubic caesium tin() halides CsSn BrCl(= 0-3) and their behaviour on heating suggest that the non-bonding tin() electrons may be involved in a band structure rather than being located in non-bonding molecular orbitals in these materials.

You might think that a hot object pushes atoms and molecules away due to radiation pressure. But a UC Berkeley team showed that for a polarizable atom, the opposite occurs: the hot object attracts it. Using an atom interferometer, they found the attraction was 20 times stronger than the gravitational attraction between a tungsten object and a cesium atom. Though negligible in most situations, next-generation gravitational wave experiments may have to take this into account.
