Context: Scopolin and scopoletin belong to the class of coumarins and have experimentally proven natural antioxidants. Natural antioxidants are crucial in mitigating the impact of oxidants in the human body through radical scavenging. Even though scopolin and scopoletin are proven antioxidants by experimental results, their antioxidant mechanisms...

Polyurethane (PU) is a widely used synthetic polymer with significant environmental concerns. Recent research into PU biodegradation, especially via protease enzymes, shows potential, yet the degradation mechanisms are not fully understood. This study investigates the binding interactions between protease and two PU variants: polybutylene adipate w...

Polyurethane (PU) has become the most dominant synthetic polymeric form, involving various industrial and day-today life applications. Even though PU provides remarkable benefits, the consequences associated with their accumulation has caused irreversible harm to the environment. The biodegradation of polymeric forms has come to the field with prom...

Context: Plastic waste pyrolysis offers a potential solution to reduce plastic accumulation, but prioritizing monomer recovery from the process is crucial to effectively address the environmental consequences of plastic accumulation. This study focuses on enhancing the yield of styrene during the pyrolysis of polystyrene by investigating thermal a...
