Polyphenols show both beneficial and harmful dose-dependent effects
This research indicates that polyphenols, which are plant compounds often described as antioxidants, can have beneficial effects at dietary levels but may cause harmful effects at higher doses because their activity depends on dose, bioavailability, and physiological context.

Sandwich panel explosion resistance depends strongly on core and bonding properties
This research indicates that sandwich panel anti-explosion performance is shaped mainly by core features, core combination, core and front face sheet thickness, structural strength and stiffness, and interfacial bond performance.
