An inhomogeneous differential equation method is used to calculate the Rayleigh and Raman scattering cross sections for atomic hydrogen and atomic caesium as functions of wavelength below and above the ionization limits. The profile of the scattering cross section near the 6s-6p resonance of atomic caesium is determined by including an energyindependent radiative width in the scattering formula...

We present direct ESI Q-TOF MS and X-ray evidence for remarkable structural and metal ion size effects on the formation of thymidine-based T-tetramers. The conventional H-bond acceptors on the ribose and deoxyribose may disfavor the formation of T-tetramers, and in the series of alkali metal ions, lithium did not induce T-tetramer due to its small ion size. Sodium, potassium, rubidium and caesi...

Single crystals of CsU(2)Te(6) were synthesized from the reaction of U, Te, and Cs(2)Te(3) at 1273 K. CsU(2)Te(6) crystallizes in the space group Cmcm in the CsTh(2)Te(6) structure type. The asymmetric unit comprises one U (site symmetry m2m), one Cs (m2m; half-occupancy) and two Te atoms (m.. and m2m). The structure of CsU(2)Te(6) consists of infinite [U(2)Te(6)] layers perpendicular to [010] ...

Chitosan–zeolite composite as a low-cost and efficient material in the removal of caesium synthetic liquid organic radioactive waste solutions.

We report population-based rates of congenital anomalies in the Rivne province of Ukraine. The rates are significantly higher in the northern half of Rivne, a region called Polissia which is polluted by Chornobyl ionizing radiation. In this region of forested wet-lands, also called Prypiat Marshlands, the soils are distinct from those in non-Polissia. The soils in Polissia transfer caesium more...

In yeast cells, of which the intracellular potassium had been partly replaced by rubidium or caesium, the intracellular ion distribution was studied by means of energy-dispersive X-ray microanalysis. The cells were rapidly frozen and thin sections were cut at low temperature on a cryo-ultramicrotome without the use of a trough liquid. By this dry cryosectioning procedure, complete retention of ...

BACKGROUND After the Chernobyl accident in 1986, as much as 5% of the released caesium-137 was deposited in Sweden due to a heavy rainfall 2 days after the event. A study of increased incidence of malignancies was initiated after the accident. METHODS The cohort included 1,137,106 inhabitants who were 0-60 years old in 1986 and lived in 8 counties of Sweden with the highest fallout of caesium...

The ethyl oxazole-4-carboxylate was directly and regioselectively alkenylated, benzylated and alkylated with alkenyl-, benzyl-, allyl- and alkyl halides in the presence of catalytic amounts of palladium acetate with caesium carbonate using Buchwald's JohnPhos ligand.
