It is important to obtain information about ways of removing radioactive cesium from foods in order to reduce internal radiation exposure from food and to ensure the safety and security of food. In this study, we investigated the change of radioactive cesium content in beef due to soaking in seasoning. Our results revealed that soaking beef in liquid seasoning (salt concentration: 8-10%) for 24...

The title compound, C14H18N4O, synthesized from an unconventional microwave-assisted method using caesium carbonate as catalyst, has an approximately planar conformation with the pyridyl and pyrazole rings inclined by a dihedral angle of 7.94 (3)°, allowing the formation of an intra-molecular N-H⋯N hydrogen bond. The supra-molecular assembly has a three-dimensional arrangement controlled mainly...

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.

Metal oxide charge carrier transporting materials have been incorporated in many ways perovskite solar cells (PSCs) because of their excellent chemical stability, wide band gaps, and reasonable mobilities. Herein, we report a low-temperature solution-processed intercalation method for introducing metal oxides displaying bipolar capability into PSCs. We intercalated p-type nickel (NiO) with cesi...

Decontamination of the radioactive cesium that is widely dispersed owing to a nuclear power station accident and concentrated in fly ash requires an effective elimination system. Radioactive fly ash contains large amounts of water-soluble cesium that can cause severe secondary contamination and represents a serious health risk, yet its complete removal is complicated and difficult. Here it is s...

2-Amino-3-acylthiophenes are known to allosterically modulate the A(1) adenosine receptor and are also used as intermediates in the synthesis of therapeutic agents and pharmacophores such as thienoazepines and thienopyrimidines. The N-alkylation of 2-aminothiophenes has been notoriously difficult to accomplish under mild conditions and there are very few examples of N-alkylated 2-aminothiophene...

background: due to the evacuation of some industrial wastewaters to arvandrood, the presence of the radionuclide material in the river is likely. the purpose of this study was to determine the radioactivity rate in arvandrood land area to the persian gulf. methods: : the concentration of cesium radionuclide (cs137) was measured in 20 sediment samples and 8 water samples which were collected fro...
