Although Ra-223 is formed naturally by the decay of U-235, for practical reasons its preparation involves neutron irradiation of Ra-226. The beta(-) decay of the Ra-227 (T-1/2 = 43 min) produced via Ra-226(n, gamma)Ra-227 reaction leads to Ac-227, a mother nuclide of Th-227 ...
give a first eluted 223Ra solution; iv) loading the 223Ra of the first eluted 223Ra solution onto a strong acid cation exchange resin; and v) eluting the 223Ra from said strong acid cation exchange resin using a second mineral acid in aqueous solution to provide a second eluted solution....
Precise measurements of the short-lived radium isotopes 223Ra and 224Ra by means of the delayed coincidence counting system (RaDeCC) rely on an efficiency calibration of this system using Mn-fiber standards for which radium activities are exactly known. We prepared seventeen different standards by ...

The cellulose of carex meyeriana kunth (CMKC) was used as raw material, and the spinning solution was prepared by combining with polyacrylonitrile (PAN). The nano-cellulose fiber of carex meyeriana kunth (CMKN) was prepared by electrospinning. Used to re
Cells were arranged closely, and the channel structures of ASCS were fully filled with neurons. The cells accumulated in the channel and grew well in good state. Conclusion: The structure of ASCS remained intact, and the neurons were closely arranged in the scaffolds. These results may lay a...

Janus particles, named after a two-faced Roman God of the same name, were suggested by Pierre-Gilles de Gennes when he made his Nobel Laureate speech to the scientific community in 1991 [1]. Since then, various Janus particles (JPs) have been synthesized, and the definition of JPs is ext...
