Autor: Naizhou Du, Xubing Wei, Xiaowei Li, Zan Chen, Shiqi Lu, Jiaqing Ding, Cunao Feng, Kai Chen, Jianghao Qiao, Dekun Zhang, Kwang-Ryeol Lee, Tiancai Zhang

Publikováno v: Friction, Vol 12, Iss 1, Pp 174-184 (2023)

Abstract The passivation of hydrogen atoms and the conformation of textured surfaces under oil-lubricated conditions are effective strategies to obtain amorphous carbon (a-C) films with extremely low friction. It is critical to understanding the infl

A Review of Selected Solutions on the Evaluation of Coal-Rock Cutting Performances of Shearer Picks under Complex Geological Conditions

Autor: Linlin Wang, Dekun Zhang, Dagang Wang, Cunao Feng

Publikováno v: Applied Sciences, Vol 12, Iss 23, p 12371 (2022)

During automatic and intelligent cutting at the coal mining face, complex geological conditions (fold structure, fault structure and magmatic intrusion) easily cause distinct occurrence conditions of coal rock seams (gangue, inclusion, or fault in th

Separation and Extraction of Mixed Grinding Chips of Artificial Joints with Different Densities by Multiple Centrifugal Separations

Autor: Cunao Feng, Yujie Zhao, Tao Zhang, Kai Chen, Xiaowei Li, Dekun Zhang

Publikováno v: Lubricants, Vol 10, Iss 9, p 226 (2022)

Aseptic loosening caused by the wear and tear of the artificial joint prosthesis after implantation is one of the main causes of artificial joint failure. Therefore, it is important to investigate the wear debris generated due to wear when developing

Electrospun fibrous membrane reinforced hydrogels with preferable mechanical and tribological performance as cartilage substitutes

Autor: Qin Chen, Xiaodong Yan, Kai Chen, Cunao Feng, Dagang Wang, Xiaowei Li, Xiaoduo Zhao, Zhimin Chai, Qingliang Wang, Dekun Zhang, Hongbo Zeng

Publikováno v: Journal of Materials Chemistry B. 11:1713-1724

The mechanical properties of PPG-4 hydrogel were comparable to natural cartilage. The friction coefficient of PPG-4 hydrogel is low as 0.039. The PPG-4 hydrogel could be widely used in tissue engineering such as cartilage replacement.

Bilayer Hydrogels with Low Friction and High Load-Bearing Capacity by Mimicking the Oriented Hierarchical Structure of Cartilage

Autor: Qin Chen, Xinyue Zhang, Kai Chen, Cunao Feng, Dagang Wang, Jianwei Qi, Xiaowei Li, Xiaoduo Zhao, Zhimin Chai, Dekun Zhang

Publikováno v: ACS applied materialsinterfaces. 14(46)

Natural articular cartilages exhibit extraordinary lubricating properties and excellent load-bearing capacity based on their penetrated surface lubricated biomacromolecules and gradient-oriented hierarchical structure. Hydrogels are considered as the
