In the present study, a facile and easily accessible method for obtaining copper-containing nanomaterials by thermolysis of copper cinnamate complex with 4′-phenyl-2,2′:6′,2″-terpyridine at 300 °C was developed. The obtained nanomaterials were studied using X-ray diffraction, atomic force microscopy, scanning electron microscopy and energy dispersi...

The frictional properties of ZDDP tribofilms at low entrainment speeds in boundary lubrication conditions have been studied in both rolling/sliding and pure sliding contacts. It has been found that the boundary friction coefficients of these tribofilms depend on the alkyl structure of the ZDDPs. For primary ZDDPs, those with linear alkyl chains giv...

In materials, the evolution of crack surfaces is intimately linked with the self-contact occuring between them. The developed contact forces not only mitigate the effect of stress concentration at crack tip but also contribute significantly to the transfer of shear and normal stresses. In this paper, we present a numerical framework to study the si...

In view of the ecological problems associated with the pollution caused by vehicles and the degradation of the ecosystem due to the extensive use of synthetic oil. There is a need to find the fuel that can substitute mineral oil and, in addition, the fuel should be environmentally friendly. Balanites aegyptiaca (Desert date) oil has the potential t...

AbstractIn recent years, the tribological contact between hard solids and glass at high temperatures has been identified as a crucial aspect in emerging technical applications like e.g., precision glass molding. To optimize such tribological systems, especially, the internal transformations of the glasses need to be considered, since these can dete...

The macroscale friction and wear properties of the Zr44Cu10Ni10Ti11Be25 metallic glass were investigated as a function of environmental oxygen concentration and contact force. We found remarkably low and predictable friction when both oxidation and frictional heating (that can lead to thermomechanically-driven crystallization) were supressed. Conve...

This paper presents a computational framework for the design of high-performance legged robotic systems. The framework relies on the concurrent optimization of hardware parameters and control trajectories to find the best robot design for a given task. In particular, we focus on energy efficiency, presenting novel electro-mechanical models to accou...

The electric-carrying nanofriction properties of graphene are vitally important in the reliability and lifetime of graphene-based micro-/nanoelectromechanical systems. However, ubiquitous atomic-scale steps on graphene have an impact on their friction properties. In this work, electric-carrying nanofriction properties of atomic-scale steps on graph...

AbstractEfforts to reliably measure AFM lateral forces have been impeded by the difficulties in obtaining appropriate calibration standards, applying those force standards to the apex of the tip, and quantifying calibration uncertainty. Here we propose a new method, Traceable Lateral Force Calibration (TLFC), which combines the reliability of direc...
