Dissipative Particle Dynamics Simulation Study on the Evolution of Photoinitiated Free Radical Polymerization Crosslinked Networks
Abstract: Gradient polymer materials overcome the limitations of conventional homogeneous polymers by integrating multiple distinct functionalities within a single continuous structure. Although photoinitiated free-radical polymerization offers excellent spatial and temporal control, the underlying microscopic mechanisms governing network evolution under non-uniform light fields remain poorly understood. In this study, a mesoscale dissipative particle dynamics (DPD) model was successfully developed to couple free-radical polymerization kinetics—including initiation, propagation, crosslinking, and termination—with exponential light attenuation …

Role and impact of Dietary Antioxidants on Aging and Lifespan: A Review
Abstract: The effect of an antioxidant-rich diet on aging and lifespan has attracted significant scientific attention, primarily through the lens of the free radical theory of aging (FRTA). This theory suggests that oxidative stress caused by an accumulation of reactive oxygen species (ROS), accelerates aging and contributes to cellular damage. The accumulation of free radicals and the oxidative damage that is induced significantly contribute to the aging process. This imbalance plays …
