One of the key points to better understand the origins of friction is to know how two surfaces in contact adhere to one another. In this paper we present molecular dynamics (MD) simulations of two aluminium bodies in contact, exposed to a range of normal l ...
Electrochemical and friction measurements during unidirectional sliding tests are used to monitor and to evaluate the tribocorrosion behavior of a passivating material. Tribocorrosion is the interplay between chemical, electrochemical, and mechanical proce ...
Fretting-corrosion is a material degradation process resulting from the combined action of a corrosive environment and small displacement fretting wear. In this work, the fretting-corrosion behavior of Ti-12.5Mo, Ti-13Nb-13Zr, and Ti-29Nb-13Ta-4.6Zr, beta ...
We have developed a thrombin-sensitive polymeric photosensitizer prodrug (T-PS) to selectively image and eradicate inflammatory lesions in rheumatoid arthritis (RA). Thrombin is a serine protease up-regulated in synovial tissues of rheumatoid arthritis (RA ...
The dry wear and tribocorrosion behaviour of pulsed plasma treated and non-treated Ni-Cr alloys sliding against alumina at 15 N were investigated by using a reciprocating wear test rig equipped with an electrochemical cell. The pulsed plasma treatment prod ...
This paper introduces the mechanical design and the control concept of the Series Compliant Articulated Robotic Leg ScarlETH which was developed at ETH Zurich for fast, efficient, and versatile locomotion. Inspired by biological systems, we seek to achieve ...
Friction and the associated wear are important but still poorly understood phenomena with strong impacts on our every day lives. Several mechanisms, such as plasticity, lattice vibration, and third-body interactions contribute to the dissipation of energy ...
Frettingwear proceeds through particle detachment from the contacting surfaces which, while trapped in the contact zone, can affect the frictional and wear response. Ball-on-flat fretting experiments were carried out between steel specimens under gross sli ...
Understanding friction has been the goal for many researchers, and although a lot is known about the factors contributing to friction, a complete picture of the origin of friction is still lacking. Besides mechanical based arguments (such as material prope ...
The purpose of this paper is to present a novel approach to study sliding friction by the use of 3D multiscale coupling techniques. We highlight the difficulties of using multiscale schemes that couple molecular dynamics (MD) with finite elements to perfor ...
