Existing methods for monitoring radionuclides in aquatic environments require frequent sampling of a large volume water, followed by tedious concentration and analytical procedures, which often make it impractical. Mussels have also been commonly employed to monitor but bioaccumulation is significantly affected physical biological factors. This study explored the feasibility using ‘Artificial M...

Layered ƒÁ-titanium phosphate (ƒÁ-TiP), Ti(HP04)2.2H20, is well known as the host material of intercalation compounds and the inorganic ion-exchanger of H+/metal ion system. It was found to have high ion-exchange selectivity for Rb+ and Cs+ among alkali metal ions. The ionexchange reactions for these ions progressed in two steps according to pH. Part of water molecules in the mterlayer of ƒÁ-Ti...

Solid/liquid interfaces are exploited in various industrial applications because confinement strongly modifies the physico-chemical properties of bulk fluids. In that context, investigating the dynamical properties of confined fluids is crucial to identify and better understand the key factors responsible for their behavior and to optimize their structural and dynamical properties. For that pur...

We carry out high-precision calculation of parity violation in a cesium atom, reducing theoretical uncertainty by a factor of 2 compared to previous evaluations. We combine previous measurements with calculations and extract the weak charge of the 133Cs nucleus, QW=-73.16(29)expt(20)theor. The result is in agreement with the standard model (SM) of elementary particles. This is the most accurate...

20 Optically pumped atomic magnetometers measure the Larmor frequency νL at which the bulk magnetization of a spin-polarized alkali metal vapour in a glass cell precesses around the field of interest B0. !e precession frequency is related to the modulus of the magnetic field by νL=(γ/2π)|B0|, where γ/2π≈3.5Hz/nT for 133Cs, so that the magnetic field measurement consists in a frequency measureme...

We report on a new experiment that tests for a violation of Lorentz invariance (LI), by searching for a dependence of atomic transition frequencies on the orientation of the spin of the involved states (Hughes-Drever type experiment). The atomic frequencies are measured using a laser cooled 133Cs atomic fountain clock, operating on a particular combination of Zeeman substates. We analyze the re...

established in 1966 as an interdisciplinary committee of the International Council of Scientific Unions (now the International Council of Science). Three years later, CODATA created the task group on fundamental constants to periodically provide the scientific and technological communities with a self-consistent set of internationally recommended values for the basic constants and conversion fa...
