The boundaries between them are the Dagoudian mountain spur, the Delingshan Mountain spur and the step zone at Xiaoshetai Gully mouth, respectively. The segments are independent for seismic activity. However, it is possible that joint ruptures between Wujiahe and Wujumengkou Dongfeng Village segments and between Dashetai and Ulan Hudong segments may occur.展开更多

The Eu@C60 monolayer has been constructed on Ag(111) substrate by one of the hexagon faces of C60 downward and its mirror plane face parallel to Ag(111). The Eu@C60 monolayer induces a recon- struction of the Ag(111) substrate and the perpendicular distance between the Eu@C60 and Ag(111) surface is 2.06 A, being shorter than that between C60 and Ag(lll) surface by 0.05A. There is no chemical bond formed between the Eu@C60 and Ag(111), and only 0.55e transferred from Ag(111) to Eu@C60. A large magnetic moment about 6.80/μB per unit cell is found for Eu@C60/Ag(111) system.展开更多
