分别以碳纳米管、炭黑以及碳纳米管和炭黑复合体作为橡胶补强剂,在开炼机上进行混炼加工制得橡胶复合材料。实验结果表明:与炭黑补强橡胶体系相比,碳纳米管能够提高橡胶复合材料弹性模量、定伸应力、耐磨和导电性能,但复合材料的拉伸强度、撕裂强度、伸长率,黏度以及加工性能都较差;而以碳纳米管和炭黑混合物作为复合补强剂,通过二者的协同补强效应,形成真正意义的"葡萄串"结构,整体地提高了橡胶复合材料的性能。当碳纳米管和炭黑的质量比为1∶4时,制备的橡胶复合材料抗撕裂强度(78.4kN/m)、硬度(68)以及磨耗(0.122cm3/km)性能都优于相同含量炭黑橡胶体系;与相同含量的碳纳米管橡胶体系相比,伸长率(470%)和黏度(65Pa.s)均大大改进。碳纳米管的加入使橡胶复合材料具有优良的动态力学性能,在低滚动滞后性和抗疲劳损失的轮胎胎面胶方面将有潜在的实用价值。

Hard carbons(HCs)are recognized as potential anode materials for sodium-ion batteries(SIBs)because of their low cost,environmental friendliness,and the abundance of their *** presence of graphitic domains,numerous pores,and disordered carbon layers in HCs plays a significant role in determining their sodium storage ability,but these structural features depend on the precursor *** influence of functional groups,including heteroatoms and oxygen-containing groups,and the microstructure of the precursor on the physical and electrochemical properties of the HC produced are evaluated,and the effects of carbonization conditions(carbonization temperature,heating rate and atmosphere)are also discussed.

Dear Editor, Phenotypic drug discovery, which observes compound effects on physiology,has given way to targeting specific molecules, but has revived by using modern methods to find drugs based on therapeutic outcomes in disease models(Vincent et al., 2022). Osteoarthritis(OA) is a prevalent chronic joint disorder, primarily affecting knee joints, with osteoclast activation due to low-grade inflammation resulting in increased bone resorption and structural changes in the joint(Katz et al.,2021).
