A Preisach Model for The Lead-Rubber Bearing Hysteresis Loop
, 2021 Lead-rubber bearings are often used as isolation/dissipation devices in the bridge structures, as they provide both, period shift and increased damping in the structure, reducing significantly the seismic forces and displacements induced in the bridge.

Advanced Materials, EarlyView.The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.
