Fabrication of layered structure VS anchor in 3D graphene aerogels as a new cathode material for lithium

Frontiers in Energy 2019, Volume 13, Issue 3,   Pages 597-602 doi: doi:10.1007/s11708-018-0576-9

Abstract: VS4 has gained more and more attention for its high theoretical capacity (449 mAh/g with 3e− transfer) in lithium ion batteries (LIBs). Herein, a layered structure VS4 anchored in graphene aerogels is prepared and first reported as cathode material for LIBs. VS4@GAs composite exhibits an exceptional high initial reversible capacity (511 mAh/g), an excellent high-rate capability (191 mAh/g at the 5 C), and an excellent cyclic stability (239 mAh/g after 15 cycles).

Seismic performance of prestressed concrete stand structure supporting retractable steel roof

Yiyi CHEN, Dazhao ZHANG, Weichen XUE, Wensheng LU

Frontiers of Structural and Civil Engineering 2009, Volume 3, Issue 2,   Pages 117-124 doi: 10.1007/s11709-009-0024-3

Abstract: The seismic behavior of a structural system composed of pre-stressed concrete stand supporting a retractable steel roof was studied, which is typically based on the prototype of engineering project of Shanghai Qizhong Tennis Center. By elasto-plastic finite element analysis and shaking table test, the following were investigated: the effects of roof configurations in opening and closing, the effect of pre-stress on the structural seismic response, and the failure mechanism of the spatial stand frame systems featured with circularly arranged columns and inverse-cone type stands. It was found that the roof status has great effect on the natural period, vibration modes, and seismic response of the whole structure, the stand response to horizontal seismic excitation is stronger in roof opening configuration than in closing state, and the response mode is dominantly translational rather than rotational, though the stand is characterized by its fundamentally torsional vibration mode. The study indicated that the pre-stressed inverse-cone stands can keep the system from global side-sway collapse under gravity loads, even in the case that most columns loose moment capacity.
