Diamond-like carbon (DLC) is a thin film material that has attracted much attention due to its properties as high wear resistance and super-low friction coefficient. Although silicon-based intermediate layers are employed ...

The use of polymeric membranes has been extensively studied for separation processes. The study of materials and methodologies for development of such membranes for cost reduction and improvement in their properties are ...

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 ...

This study aims at analysing the ideal rate of two stabilizers in elastomeric compounds, used in tires that require a long-term performance, submitted to different kinds of aging. The resistance to the aging can be achieved ...

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, ...

The interaction modes of polyhedral oligomeric silsesquioxane (POSS) of closed cages with distinct functional groups were evaluated on isotactic polypropylene (iPP) nanostructuration via reactive processing. POSS were ...

This paper presents the nitriding experimental investigation of partially yttria stabilized zirconia (3 mol%), in particular, plasma generated by radiofrequency (RF), using two distinct methods: i) plasma nitriding, by ...

Dimensional deviation and surface quality are fundamental components for mechanical applications. The variables that influence these factors, the quantity of heat generated must be reduced in order to minimize their effects ...

One of the major challenges in the rubber industry today is related to the relationship between durability, safety and economy for tire applications. Important progress on rolling resistence reduction with good wet grip ...
