Erosion Resistance Enhancement in Epoxy Composites by Recycled Rubber: Effect of Rubber Type
Polymer Engineering &Science, EarlyView.Erosion resistance enhancement in epoxy composites by recycled rubber. ABSTRACT Epoxy‐based materials have low erosion resistance due to their brittle nature, and toughness modification stands out for enhancing it. At this stage, the use of waste rubber as a reinforcement component in the composite system is of interest due to its role in providing ...

River‐Scale Evaluation of a Floating LED Light Array for Behavioral Guidance of American Eel
River Research and Applications, EarlyView.ABSTRACT Exploiting the sensory physiology of migratory fishes to guide them away from hazards like hydroelectric turbines is of interest to regulatory agencies and hydropower operators to achieve conservation and management goals. Here we describe a river‐scale experiment where out‐migrating adult American eel (Anguilla rostrata) were tracked ...
