Antimony(Sb)is an intriguing anode material for Li-ion batteries(LIBs)owing to its high theoretical capacity of 660 m Ah·g^(-1)and appropriate working potential of~0.8 V(***^(+)/Li).However,just like all alloying materials,the Sb anode suffers from huge volume expansion(230%)during repeated insertion/extraction of Li+ions,resulting in structural deterioration and rapid capacity *** this work,a novel amorphous Sb/C composite with atomically dispersed Sb particles in carbon matrix is prepared via a straightforward high-energy ball milling *** intimate intermixing of amorphous Sb with C provides homogeneous element distribution and isotropic volume expansion during cycling,resulting in persistent structural ***,the disordered structure of amorphous material shortens the diffusion distance of lithium ions/electrons,promoting fast reaction kinetics and rate *** from the aforementioned effects,the amorphous Sb/C exhibits a high reversible capacity of537.4 m Ah·g^(-1)at 0.1 A·g^(-1)and retains 201.0 m Ah·g^(-1)at an ultrahigh current rate of 10.0 A·g^(-1).Even after 1500deep cycles at 2.0 A·g^(-1),the amorphous Sb/C electrode still maintains 86.3%of its initial capacity,which outperforms all existing Sb-based anodes reported so *** analysis further reveals a greatly reduced volume variation of merely 34.6%for the amorphous Sb/C electrode,much lower than that of 223.1%for crystalline Sb *** study presents a new approach to stabilizing Sb-based alloy anodes and contributes to the construction of high-performance amorphous anode materials for LIBs,enabling advanced energy storage.

World Journal of Hepatology 2012年第7期4卷 224-230页

作者： Wei-Hui Sun Ming-Quan Song chang-qing jiang Yong-Ning Xin et al. Jian-Lin Ma Ying-Xun Liu Lei Ma Zhong-Hua Lin chang-Yan Li Ling Liu Mei Zhang Lei-Lei Chu Xiang-Jun jiang Qiang Wan Lin Zhou Rong Ren Ling-Fang Meng Wei-Hui Sun Jian-Lin Ma Ying-Xun Liu Lei Ma Qiang Wan Lin Zhou Rong Ren Ling-Fang Meng Hepatology Department Qingdao Chengyang People's Hospital Qingdao 266100 Shandong Province China.

AIM: To evaluate the effect of a 6 and 12 mo lifestyle modification intervention in nonalcoholic fatty liver diseases (NAFLD) in Chengyang District of qingdao. METHODS: Participants with NAFLD who had resided in Chengyang District for more than 5 years were enrolled in this study. After the 6 and 12 mo lifestyle modification intervention based on physical activity, nutrition and behavior therapy, parameters such as body weight, body mass index (BMI), waist circumference, serum alanine aminotransferase (ALT), aspartate aminotransferase values, serum cholesterol, triglycerides, fasting glucose, fasting insulin and visceral fat area (VFA), the liver-spleen ratio and the homeostasis model assessment of insulin resistance (HOMA-IR) were evaluated and compared between participants with and without the intervention. RESULTS: Seven hundred and twenty-four participants were assigned to the lifestyle intervention group (LS) and 363 participants were assigned to the control group (CON). After the intervention, body weights in the LS group were significantly decreased compared to those in the CON group at 6 mo (11.59% ± 4.7% vs 0.4% ± 0.2%, P = 0.001) and at 12 mo (12.73% ± 5.6% vs 0.9% ± 0.3%, P = 0.001). Compared with the CON group, BMI was more decreased in the LS group after 6 and 12 mo (P = 0.043 and P = 0.032). Waist circumference was more reduced in the LS group than in CON (P = 0.031 and P = 0.017). After the 6 and 12 mo intervention, ALT decreased significantly in the LS group (P = 0.003 and P = 0.002). After 6 and 12 mo, the metabolic syndrome rate had decreased more in the LS group compared with the CON group (P = 0.026 and P = 0.017). After 12 mo, the HOMA-IR score decreased more obviously in the LS group (P = 0.041); this result also appeared in the VFA after 12 mo in the LS group (P = 0.035). CONCLUSION: Lifestyle intervention was effective in improving NAFLD in both 6 and 12 mo interventions. This intervention offered a practical approach for treating a large num
