Researchers Report a Surface Modification Method to Improve Corrosion Resistance of Steel to Liquid Lead-bismuth Eutectic

Researchers at IMP used the shot peening process to nanocrystallise the surface of ferrite/martensitic steel SIMP, a candidate structural material for lead-cooled fast reactors. They investigated the corrosion behaviour of the SP samples exposed to liquid LBE, in comparison with that of the original coarse grain (CG) samples.

Scientists Probe Nature of Reported Low-spin Wobbling Bands in Atomic Nuclei

A research team led by the scientists at IMP has explored the nature of the reported low-spin wobbling bands in atomic nuclei. New investigation suggests that the nuclear wobbling interpretation is not feasible at low spins.
　　Nuclear wobbling is becoming an intriguing subject as it describes a nucleus rotating around rotating axis in its body frame, in analogy with the precession in the macroscopic world. Since the...
