| 1 | Investigation of reinforcement of the modified carbon black from wasted tires by nuclear magnetic resonance显示文摘Pyrolysis has the potential of transforming waste into recyclable products. Pyrolytic carbon black (PCB) is one of the most important products from the pyrolysis of used tires. Techniques for surface modifications of PCB have been developed. One of the most significant applications for modified PCB is to reinforce the rubber matrix to obtain high added values. The transverse relaxation and the chain dynamics of vulcanized rubber networks with PCB and modified PCB were studied and compared with those of the commercial carbon blacks using selective 1H transverse relaxation (T2) experiments and dipolar correlation effect (DCE) experiments on the stimulated echo. Demineralization and coupling agent modification not only intensified the interactions between the modified PCB and the neighboring polyisoprene chains, but also increased the chemical cross-link density of the vulcanized rubber with modified PCB. The mechanical testing of the rubbers with different kinds of carbon blacks showed that the maximum strain of the rubber with modified PCB was improved greatly. The mechanical testing results confirmed the conclusion obtained by nuclear magnetic resonance (NMR). PCB modified by the demineralization and NDZ-105 titanate coupling agent could be used to replace the commercial semi-reinforcing carbon black. | ZHOU Jie YANG Yong-rong REN Xiao-hong STAPF Siegfried | 2006 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2006，7，8： | 10 |
| 2 | PE100管材料的聚集态结构和性能的固体NMR分析显示文摘PE100管材料基体树脂中界面区的含量比较高(高于10%),而完全无定形区的含量极低.界面区含量表征非晶区中运动部分受阻的链段所占的比重,因而上述结果意味着PE100管材料中非晶区中链段表现出强烈的缠结倾向.界面区的含量(或非晶区的组成特征)决定了材料的耐慢速裂纹增长性能,而固相区含量则决定了材料的力学强度,两种影响因素的平衡决定了最终管材料的长期使用性能. | 严小伟 历伟 任晓红 王靖岱 阳永荣 Siegfried Stapf Bernhard Blumich | 2008 | 材料研究学报2008，22，2： | 10 |
| 3 | 未经治疗脑动静脉畸形患者出血的预测因素显示文摘Background: Intracranial hemorrhage is a serious possible complication in patients with brain arteriovenous malformation (AVM). Several morphologic factors associated with hemorrhagic AVM presentation have been established, but their relevance for the risk of subsequent AVM hemorrhage remains unclear. Methods: The authors analyzed follow-up data on 622 consecutive patients from the prospective Columbia AVM database, limited to the period between initial AVM diagnosis and the start of treatment (i.e., any endovascular, surgical, or radiation therapy). Univariate and multivariate logistic regression and Cox proportional hazard models were applied to analyze the effect of patient age, gender, AVM size, anatomic location, venous drainage pattern, and associated arterial aneurysms on the risk of intracranial hemorrhage at initial presentation and during follow-up. Results: The mean pretreatment follow-up was 829 days (median: 102 days), during which 39 (6%) patients experienced AVM hemorrhage. Increasing age (hazard ratio [HR] 1.05, 95%CI 1.03 to 1.08), initial hemorrhagic AVM presentation (HR 5.38, 95%CI 2.64 to 10.96), deep brain location (HR 3.25, 95%CI 1.30 to 8.16), and exclusive deep venous drainage (HR 3.25, 95%CI 1.01 to 5.67) were independent predictors of subsequent hemorrhage. Annual hemorrhage rates on follow-up ranged from 0.9%for patients without hemorrhagic AVM presentation, deep AVM location, or deep venous drainage to as high as 34.4%for those harboring all three risk factors. Conclusions: Hemorrhagic arteriovenous malformation (AVM) presentation, increasing age, deep brain location, and exclusive deep venous drainage appear to be independent predictors for AVM hemorrhage during natural history follow-up. The risk of spontaneous hemorrhage may be low in AVMs without these risk factors. | Stapf C. Mast H. Sciacca R. R. 邱伟庆(译) | 2006 | 世界核心医学期刊文摘(神经病学分册)2006，2，9： | 8 |
