Structural Lubricity and Molecular Contamination: Rejuvenation, Aging, and Friction Switches
Wai H. Oo, Hongyu Gao, Martin H. Müser +1
Using atomic force microscopy experiments and molecular dynamics simulations of gold nanoislands on graphite, we investigate why ultra-small friction commonly associated with struc…
A Computational Study of Cluster Dynamics in Structural Lubricity: Role of Cluster Rotation
Wai H. Oo, Mehmet Z. Baykara, Hongyu Gao
We present a computational study of sliding between gold clusters and a highly oriented pyrolytic graphite substrate, a material system that exhibits ultra-low friction due to stru…
True Atomic-Resolution Imaging under Ambient Conditions via Conductive Atomic Force Microscopy
Saima A. Sumaiya, Mehmet Z. Baykara
Atomic-scale characteristics of surfaces dictate the principles governing numerous scientific phenomena ranging from catalysis to friction. Despite this fact, our ability to visual…
Intercalation Leads to Inverse Layer Dependence of Friction on Chemically Doped MoS_{2}
Ogulcan Acikgoz, Enrique Guerrero, Alper Yanilmaz +4
We present results of atomic-force-microscopy-based friction measurements on Re-doped molybdenum disulfide (MoS2). In stark contrast to the widespread observation of decreasing fri…
The Potential of TiCT Nano-sheets (MXenes) for Nanoscale Solid Lubrication Revealed by Friction Force Microscopy
A. Rodriguez, M. S. Jaman, O. Acikgoz +5
TiCT nano-sheets (MXenes) are an emerging class of two-dimensional materials with outstanding potential to be employed in energy storage, catalysis, and triboelectric a…
Direct Imaging, Three-dimensional Interaction Spectroscopy, and Friction Anisotropy of Atomic-scale Ripples on MoS
Omur E. Dagdeviren, Ogulcan Acikgoz, Peter Grutter +1
Theory predicts that two-dimensional (2D) materials may only exist in the presence of out-ofplane deformations on atomic length scales, frequently referred to as ripples. While suc…
Solid Lubrication with MoS: A Review
Mohammad R. Vazirisereshk, Ashlie Martini, David A. Strubbe +1
Molybdenum disulfide (MoS) is one of the most broadly utilized solid lubricants with a wide range of applications, including but not limited to those in the aerospace/space ind…
Interface and electronic characterization of thin epitaxial Co3O4 films
C. A. F. Vaz, H. -Q. Wang, C. H. Ahn +10
The interface and electronic structure of thin (~20-74 nm) Co3O4(110) epitaxial films grown by oxygen-assisted molecular beam epitaxy on MgAl2O4(110) single crystal substrates have…
