Magnetomigration of Rare-Earth Ions Triggered by Concentration Gradients

Proposal for laser-cooling of rare-earth ions

Interactions between rare-earth ions and DNA of Bashibai sheep.

The interaction between rare-earth ions and DNA from Bashibai sheep was studied by microcalorimetry and electrochemistry. The DNA chain was found to have four to five binding sites for rare-earth ions. The binding affinity was about 10⁻⁵-10⁻⁶ M. It was also found that smaller ions caused more heat to be released in the process of binding and bound more readily to the nucleic acid chain. This is...

Self-propelled droplets for extracting rare-earth metal ions.

We have developed self-propelled droplets having the abilities to detect a chemical gradient, to move toward a higher concentration of a specific metal ion (particularly the dysprosium ion), and to extract it. Such abilities rely on the high surface activity of di(2-ethylhexyl) phosphoric acid (DEHPA) in response to pH and the affinity of DEHPA for the dysprosium ion. We used two external stimu...
