Journal ArticleDOI
Tribo-biological deposits on the articulating surfaces of metal-on-polyethylene total hip implants retrieved from patients.
TL;DR: Results showed that the attached tribo-layer contained not only denatured proteins but also a fraction of polymer particles, suggesting that enhancing interface lubrication may be more effective on reducing wear than increasing the hardness of material.
Journal ArticleDOI
Parameters Identification of Rubber-like Hyperelastic Material Based on General Regression Neural Network
TL;DR: In this paper , the authors presented a systematic scheme to identify the material parameters in constitutive model of hyperelastic materials such as rubber based on the combined use of general regression neural network, experimental data and finite element analysis.
Journal ArticleDOI
Line Scan Reconstruction: A Viable Approach for Tracking Atomic Stick–Slip Events and True Tip Position in Atomic Force Microscopy
Quanzhou Yao,Qunyang Li +1 more
TL;DR: In this paper, an approach to reconstruct the atomic stick-slip process such that individual slip events with arbitrary slip distance can be automatically identified, while the slip forces and true tip position can be obtained simultaneously.
Journal ArticleDOI
Tunable friction of monolayer MoS2 by control of interfacial chemistry
Weibing Chen,Chenwei Tang,Tianyi Li,Xiaolong Zou,Jing Zhang,Shuai Jia,Jiangtan Yuan,Antony George,Dmitri V. Voronine,Pulickel M. Ajayan,Qunyang Li,Ling Hao,Jun Lou +12 more
TL;DR: In this paper, the authors utilized the heterostructures of monolayer MoS2 and self-assembled monolayers (SAMs) of organic molecules as a platform to understand how carrier density of nanomaterials affects their friction behaviors.
Journal ArticleDOI
Sequential growth and twisted stacking of chemical-vapor-deposited graphene
Jinglan Liu,Xuewei Zhang,Shuai Zhang,Zhenxing Zou,Zilong Zhang,Zehao Wu,Yang Xia,Qunyang Li,Pei Zhao,Hongtao Wang +9 more
TL;DR: In this article, the authors investigated the CVD growth of graphene adlayers on copper (Cu) using isotope-labeling-based Raman spectroscopy and high-resolution atomic force microscopy (AFM).
