Anthropogenic particles at the microscale and nanoscale are posing risks to human health ecosystem. Engineered nanomaterials, microplastics nanoplastics, soot, road tire wear a few prominent examples of that either intentionally manufactured or incidentally produced released into environment. Analytical developments in past decades have made it possible study nanoscale; however, there is still ...

In this study, functionally graded Ni-Al2O3 composite coating (FGN-A) has been produced from nickel Watt’s bath containing different concentrations of Al2O3 particles. For this, different composite coatings were electroplated in the same bath with different particles concentration to find the optimum concentration of particles in which the maximum content with uniform distribution of Al2O3 part...

In ground vehicles, tire consumption is, in general, mainly due to the mileage covered, and fact, life span of tires, at least common situations, is rather long. aeronautical context, for aircraft particular, instead, plays a crucial role determining maintenance costs. This fact that, braking, nearly all maneuvers activate antiskid controller, which remains use long time intervals. anti-lock br...

In this research, surface composite layers containing nano sized TiB2, Al2O3-TiB2, ZrO2 and CNT particles have been fabricated on Aluminum alloy substrates by friction stir processing. The effects of different processing variables such as number of passes and strengthening particle distribution, hardness, and wear properties of surface nano...

With many years of construction and application of common concrete, researchers have always been searching for a better composition. One of the notable ideas for achieving such a composition is using recycled materials. One of the materials which is suitable for environment and constant development is damaged tires .For studying mechanical properties of concrete containing tire particles, a ser...

Tires’ substantial environmental footprint is set to drop as producers increase their use of renewable materials and efficient technologies emerge for chemically recycling them. Currently, most tires are incinerated or landfilled, at a high price. While the sector’s may be shrinking, millions metric tons rubber particles get released annually wear down on roads. And independent scientists say t...

Fractals can be very useful when applied to tribology. Fractal descriptions of wear particles require surface texture information to be processed. The morphology of wear particles depends on its surface characteristics. These characteristics are represented by fractal dimension derived from the boundary profile. In this paper, Fractal dimension is used to describe wear particles obtained from e...

Introduction: Polyethylene wear particles induce macrophages to release cytokines, which can lead to osteolysis and aseptic loosening of total joint prostheses. The generation of polyethylene wear particles is one of the most important factors that affect the midterm and long-term clinical results associated with total knee arthroplasty (TKA). Therefore, to achieve better long-term results for ...
