2Self-assembled dandelion-like NiS nanowires on biomass-based carbon aerogels as electrode material for hybrid supercapacitors显示文摘Carbon aerogels derived from biomass have low specific capacity due to the underutilized structure,limiting their application in high-performance supercapacitors.In this work,the hierarchical nickel sulfide/carbon aerogels from liquefied wood(LWCA-NiS)were synthesized via a simple two-step hydrothermal method.Benefitting from the unique 3D coral-like network structure of LWCA,selfassembled NiS nanowires with the dandelion-like structure showed high specific surface(389.1 m^(2)·g^(−1))and hierarchical pore structure,which increased affluent exposure of numerous active sites and structural stability,causing superior energy storage performance.As expected,LWCA-NiS displayed high specific capacity(131.5 mAh·g^(−1) at 1 A·g^(−1)),good rate performance,and highly reversible and excellent cycle stability(13.1%capacity fading after 5000 cycles)in the electrochemical test.Furthermore,a symmetrical supercapacitor using LWCA-NiS-10 as the electrode material delivered an energy density of 12.7 Wh·kg^(−1) at 299.85 W·kg^(−1).Therefore,the synthesized LWCA-NiS composite was an economical and sustainable candidate for the electrodes of highperformance supercapacitors.Chunfei Lv Ranran Guo Xiaojun Ma Yujuan Qiu 2023Frontiers of Materials Science2023,17,3:0
3The older the better:The characteristic of localized prostate cancer in Chinese men显示文摘Objective:To assess the clinicopathological features and overall survival between two groups of Chinese patients older or younger than 70 years after retropubic radical prostatectomy.Methods:From January 2001 to February 2010,390 patients receive dretropubic radical prostatectomy.After excluding 89 patients with adjuvant or neoadjuvant hormonal therapy or radiotherapy,a total of 301 patients were included in this study.We arbitrarily divided these patients into younger age group(<70 years,140 cases,46.5%)and older age group(≥70 years,161 cases,53.5%).The differences in serum prostate specific antigen(PSA),Gleason score,clinical tumor stage,and biochemical-free survival were analyzed between the two groups.Results:There were not significant differences between the two groups in high Gleason score rate and clinical tumor stage.However,older patients had significantly lower biochemical recurrence rate than those of younger patients,and had significantly higher PSA levels.Multivariate analysis showed that older age,PSA level and clinical tumor stage were significantly associated with biochemical recurrence free survival.Conclusion:In Chinese men,older age(≥70 years)is associated with better outcome.If the physical condition permits,older age alone should not exclude patients from radical prostatectomy.Haifeng Wang Xu Gao Ziyu Fang Xin Lu Yan Wang Chunfei Ma Zhenkai Shi Bo Yang Shancheng Ren Chuanliang Xu Yinghao Sun 2015Asian Journal of Urology2015,2,3:0
