The functionalized process refers to a new concept, which aims to modify the physical and chemical properties of the original surface for specific purposes. Hence, the functional surfaces will introduce the desired properties that can not be found in the original material. The various applications might be named liquid repellent, anti-icing, anti-r...

The supply of conventional light petroleum is being depleted, leading to increasing dependence on unconventional oil sources such as heavy oil. Heavy oil often contains a significant amount of heavy fraction asphaltene. During heavy oil upgrading, asphaltenes promote the formation of high-molecular-weight coke, which can cause issues, including cat...
