摘要

通过电沉积镍，在核径迹聚碳酸酯膜的孔内生长出长度为11µm、直径为800和15nm的镍纳米线。采用扫描电镜(SEM)、透射电镜(TEM)和x射线衍射(XRD)对制备的纳米线的表面形貌和晶体结构进行了表征。实验结果表明，低电流密度可获得较好的效果，而高电流密度会导致卷曲纳米线的形成。进一步研究了制备的纳米线的电学性能，发现纳米线符合欧姆定律。通过结构表征，观察到制备的纳米线具有FCC晶格结构。

FABRICATION AND CHARACTERIZATION OF NICKEL NANOWIRES

This paper shows that nickel nanowires of length 11 µm and diameters 800 and 15nm were grown within the pores of nuclear track polycarbonate membrane by electrodepositing nickel. Surface morphology and crystallographic structure of the deposited nanowires was investigated using SEM, TEM and XRD respectively. It is found that low current density gives good result, while high current density leads to the formation of curled nanowires. Fabricated nanowires were further investigated for electrical properties and found that nanowires obey ohm’s law. Through structural characterization it has been observed that the fabricated nanowires posses FCC lattice structure.

期刊介绍： We would like to inform you, that iJOE, the ''International Journal of Online Engineering'' will accept now also papers in the field of Biomedical Engineering and e-Health''. iJOE will therefore be published from January 2019 as the ''International Journal of Online and Biomedical Engineering''. The objective of the journal is to publish and discuss fundamentals, applications and experiences in the fields of Online Engineering (remote engineering, virtual instrumentation and online simulations, etc) and Biomedical Engineering/e-Health. The use of cyber-physical systems, virtual and remote controlled devices and remote laboratories are the directions for advanced teleworking/e-working environments. In general, online engineering is a future trend in engineering and science. Due to the growing complexity of engineering tasks, more and more specialized and expensive equipment as well as software tools and simulators, shortage of highly qualified staff, and the demands of globalization and collaboration activities, it become essential to utilize cyber cloud technologies to maximize the use of engineering resources. Online engineering is the way to address these issues. Considering these, one focus of the International Journal of Online and Biomedical Engineering is to provide a platform to publish fundamentals, applications and experiences in the field of Online Engineering, for example: Remote Engineering Internet of Things Cyber-physical Systems Digital Twins Industry 4.0 Virtual Instrumentation. An important application field of online engineering tools and principles are Biomedical Engineering / e-Health. Topics we are interested to publish are: Automation Technology for Medical Applications Big Data in Medicine Biomedical Devices Biosensors Biosignal Processing Clinical Informatics Computational Neuroscience Computer-Aided Surgery.
