Melting temperatures, Tm, were systematically studied for a set of 92 DNA duplex oligomers in a variety of sodium ion concentrations ranging from 69 mM to 1.02 M. The relationship between Tm and ln [Na+] was nonlinear over this range of sodium ion concentrations, and the observed melting tem...
The synthesis of small particles through the interaction between chitosan (CS) and sodium lauryl ether sulfate (SLES) was studied. Depending on working condition, microparticles at atmospheric pressure and ultrafine particles at high pressure have been obtained. At atmospheric pressure, the microparticles...
It was found that the percentage of arsenic recovery increased with the concentration of sodium hydroxide and was almost constant after 0.5 M due to the limitation of mass transfer area of the hollow fibers. After 3-cycle separation, the extraction and recovery of arsenic ions from produced ...
Studies on the doubly charged cluster ions of sodium and potassium nitrates by electrospray ionization tandem mass spectrometry Doubly charged cluster ions, besides singly charged cluster ions, from sodium and potassium nitrates were produced evidently under normal source capillary ...

摘要: Metallic sodium formed upon thermal decomposition of NaN 3 migrates from the external surface of zeolite into its pore system. Interaction takes place between neutral sodium and ionic cesium, too, as proved by ESR spectroscopy.关键词:...

When a solution containing the monoanions is subjected to further contact with sodium, dianions are formed with characteristic long-wavelength absorption bands which are particularly well defined in the case of the dianion prepared from the safranine base OS 2- (Fig. 2). The correctness of the ...
Aluminum was also effectively removed from WW1, but slightly poorer results were achieved with WW2. It is thought that in this sample, the metals were not completely in the free, ionic form favor- able for complexation. Unexpectedly, sodium and potassium were also partially removed, possibly ...
