Nanoindentation Test of Ion-Irradiated Materials: Issues, Modeling and Challenges.

Exposure of metals to neutron irradiation results in an increase in the yield strength and a significant loss of ductility. Irradiation hardening is also closely related to the fracture toughness temperature shift or the ductile-to-brittle transition temperature (DBTT) shift in alloys with a body-centered cubic (bcc) crystal structure. Ion irradiation is an indispensable tool in the study of the radiation effects of materials for nuclear energy systems.

The complete chloroplast genome of .

() is a medicinal plant in China, which has been well known for its activities against leprosy and cancers. In this study, we assembled and characterized the complete chloroplast (cp) genome sequence of in an effort to provide genomic resources for promoting its conservation. The cp genome is 156,231 bp in length, containing a pair of 23,720 bp inverted repeat (IR) regions, which is separated by a large single copy region (LSC) of 88,214 bp and a small single copy region (SSC) of 20,577 bp.
