Polymeric materials having good mechanical properties combined with flexibility are requirements to meet changing needs of the industry. These requirements can be met with the production of dynamically vulcanized/crosslinked ...

The use of additives from alternative sources to petrochemical has attracted the interest of many academic researches and applications. The inputs as soybean oil have great potential in the polymer modification. However, ...

In this work, amorphous hydrogenated carbon (a-C:H) thin films were deposited using a simple, low cost and efficient pulsed DC - plasma-enhanced chemical vapor deposition technique improved by electrostatic confinement ...

The search for renewable energy sources is a subject of great interest worldwide due to growing energy demand, instability in oil prices and environmental problems. In this context, the self-assembled thin films have ...

Austenitic stainless steel materials are widely used in systems that require high oxidation resistance and corrosion resistance. However, in contact with other surfaces, these materials show a high coefficient of friction ...

Zinc oxide nanoparticle (nano ZnO) is a kind of inorganic multifunctional filler, which has extensive uses in rubber additives. Notably, most of relevant researches about nano ZnO focused on using them as a substitute of ...

The deposition of thin films can be employed to modify and/or functionalize the properties of a material’s surface, improving wear resistance (tribological properties) or changing the resistivity (electrical properties). ...

The incorporation of vegetable oils into the development of tread rubber formulation has been one of the alternatives to reduce the use of oil with high contents of aromatic polycyclics. Many studies suggest the substitution ...

This research has determined the parameters of powder metallurgy in order to use the wasted powder from the shot blasting process and transform it in components. The wasted was evaluated by its physical and micro-structural ...
