The Kolmogorov-Smirnov test for three redshift distributions of long gamma-ray bursts in the Swift Era

引用

Chinese Journal of Astronomy and Astrophysics 2009年第1期9卷 95-101页

作者： yun-Ming dong tan Lu College of Physics and Electronic Engineering Sichuan Normal University Chengdu 610066China Purple Mountain Observatory Chinese Academy of Sciences Nanjing 210008 China

We investigate redshift distributions of three long burst samples, with the first sample containing 131 long bursts with observed redshifts, the second including 220 long bursts with pseudo-redshifts calculated by the variability-luminosity relation, and the third including 1194 long bursts with pseudo-redshifls calculated by the lag-luminosity relation, respectively. In the redshift range 0-1 the Kolmogorov-Smirnov probability of the observed redshift distribution and that of the variability-luminosity relation is large. In the redshift ranges 1-2, 2-3, 3-6.3 and 0-37, the Kolmogorov-Smirnov probabilities of the redshift distribution from lag-luminosity relation and the observed redshift distribution are also large. For the GRBs, which appear both in the two pseudo-redshift burst samples, the KS probability of the pseudo-redshift distribution from the lag-luminosity relation and the observed reshift distribution is 0.447, which is very large. Based on these results, some conclusions are drawn： i） the V-Liso relation might be more believable than the τ-Liso relation in low redshift ranges and the τ-Liso relation might be more real than the V-Liso relation in high redshift ranges; ii） if we do not consider the redshift ranges, the τ-Liso relation might be more physical and intrinsical than the V-Liso relation.

Enhanced structural stability and durability in lithium-rich manganese-based oxide via surface double-coupling engineering

引用

Journal of Energy Chemistry 2024年第11期 274-283页

作者： Jiayu Zhao Yuefeng Su Jinyang dong Xi Wang yun Lu Ning Li Qing Huang Jianan Hao Yujia Wu Bin Zhang Qiongqiong Qi Feng Wu Lai Chen School of Materials Science and Engineering Beijing Key Laboratory of Environmental Science and Engineering Beijing Institute of Technology Chongqing Innovation Center Beijing Institute of Technology Yibin Libode New Materials Co. Ltd. Initial Energy Science & Technology (Xiamen) Co. Ltd

Lithium-rich manganese-based oxides（LRMOs） exhibit high theoretical energy densities, making them a prominent class of cathode materials for lithium-ion batteries. However, the performance of these layered cathodes often declines because of capacity fading during cycling. This decline is primarily attributed to anisotropic lattice strain and oxygen release from cathode surfaces. Given notable structural transformations, complex redox reactions, and detrimental interface side reactions in LRMOs, the development of a single modification approach that addresses bulk and surface issues is challenging. Therefore,this study introduces a surface double-coupling engineering strategy that mitigates bulk strain and reduces surface side reactions. The internal spinel-like phase coating layer, featuring threedimensional（3D） lithium-ion diffusion channels, effectively blocks oxygen release from the cathode surface and mitigates lattice strain. In addition, the external Li3PO4coating layer, noted for its superior corrosion resistance, enhances the interfacial lithium transport and inhibits the dissolution of surface transition metals. Notably, the spinel phase, as excellent interlayer, securely anchors Li3PO4to the bulk lattice and suppresses oxygen release from lattices. Consequently, these modifications considerably boost structural stability and durability, achieving an impressive capacity retention of 83.4% and a minimal voltage decay of 1.49 m V per cycle after 150 cycles at 1 C. These findings provide crucial mechanistic insights into the role of surface modifications and guide the development of high-capacity cathodes with enhanced cyclability.
