Concentration performance of solar collector integrated compound parabolic concentrator and flat microchannel tube with tracking system
Xu, R; He, Z; Yang, L; Xu, S; Wang, R; Wang, H (Elsevier, 2022-10-17)The compound parabolic concentrator is a non-imaging concentrator that can concentrate solar radiation without tracking system. However, as the concentration ratio increases, the maximum half acceptance angle and the ... -
Fine structural changes of fluid catalytic catalysts and characterization of coke formed resulting from heavy oil devolatilization
Zhang, YS; Lu, X; Owen, RE; Manos, G; Xu, R; Wang, FR; Maskell, WC; Shearing, PR; Brett, DJL (2020-04-01)Coke formation from heavy oil cracking and the associated change in the porous structure of fluid catalytic cracking (FCC) catalysts has been studied using a comprehensive range of techniques, including 2D and 3D imaging ... -
In situ visualization by X-Ray computed tomography on sulfur stabilization and lithium polysulfides immobilization in S@HCS/MnO<inf>x</inf> cathode
Xu, R; Xiang, J; Feng, J; Lu, X; Hao, Z; Kang, L; Li, M; Wu, Y; Tan, C; Liu, Y (Elsevier, 2020-10-01)The lithium-sulfur (Li-S) batteries have high theoretical energy density, exceeding that of the lithium-ion batteries. However, their practical applications are hindered by the capacity decay due to lithium polysulfide ... -
Precisely visit the performance modulation of functionalized separator in Li-S batteries via consecutive multiscale analysis
Hao, Z; Chen, J; Lu, X; Kang, L; Tan, C; Xu, R; Yuan, L; Brett, DJL; Shearing, PR; Wang, FR (Elsevier, 2022-08-01)Despite progress of functionalized separator in preventing the shuttle effect and promoting the sulfur utilization, the precise and non-destructive investigation of structure-function-performance associativity remains ...
