Hybrid Graphene Oxide/Carbon Black Reinforcement in Natural Rubber: A Sustainable Approach for Multifunctional Tire Tread Compounds

Carbon black (CB) is the primary reinforcing filler in tire tread elastomers; however, high filler loadings increase hysteresis and accelerate aging. In this context, hybrid reinforcement strategies incorporating graphene oxide (GO) have attracted considerable attention due to the unique mechanical and thermal properti...

Functionalization of Chitosan and Application in Nanocomposites for Methyl Orange Adsorption

The production of efficient adsorbents for azo dye removal by synthesizing and evaluating aminosilane-modified chitosan (S-Chi), as well as the formation of nanocomposites containing magnetite (Mgt) and silver nanoparticles (AgNPs), is addressed in this work. The nanocomposites were prepared using a suspension techni...
