The automotive industry is facing worldwide pressure to reduce carbon emission to meet the Paris Accord target of 2 °C increase in global average temperature by the end of the century. One way to reduce carbon emission is to improve fuel economy of

Modern engineering surfaces are cut, grind, and polished to create surfaces that are isotropic, uniform, and homogeneous to enable easy assembly and manufacture. Commonly used surface descriptors such as Ra are based on these characteristics. In the

Surface texturing to control friction and wear has been the focus of numerous studies in the last few decades. Despite this interest, understanding the underlying causes for surface texturing effects under different contact and lubrication conditions

Friction. 2:1-26
Friction is an essential part of human experience. We need traction to walk, stand, work, and drive. At the same time, we need energy to overcome the resistance to motion, hence, too much friction costs excess energy to perform work, introducing inef

Nanolubrication is emerging to be the key technical barrier in many devices. One of the key attributes for successful device lubrication is self-sustainability using only several molecular layers. For single molecular species lubrication, one desires

Tribochemistry can be defined as the chemical reactions between the surface and the lubricant molecules inside a sliding contact under boundary lubrication conditions. These reactions are important because they control the lubrication processes, and

Self-assembled monolayers have increasingly been explored as potential protective films in devices against friction and adhesion. However, detailed characterization of the monolayer film structure is difficult. This article utilizes a combination of

Microfabricated surface textures have been applied to generate narrowly distributed UHMWPE wear particles with different sizes and shapes. The purpose is to study the effects of UHMWPE induced bioactivity that leads to the failure of total joint impl

Patterned lubricant films on magnetic hard disks offer potential advantages in controlled bonding sites, higher average shear strength, and longer durability. However, since the lubricant film thickness is at 1 or 2 nm, characterization of the patter
