Pavement Drainage and Pavement-Shoulder Joint Evaluation and Rehabilitation
, 1993 The objectives of this research were to i) evaluate the performance of pavement subdrainage systems, ii) study the behavior of moisture conditions below pavements, and iii) provide recommendations for improved drainage criteria based on analysis of field data. Existing and retrofitted subdrainage collector systems were inspected through external visual

Atom‐Efficient Cerium‐Based Molecular Cages as Biocompatible Reactive Oxygen Scavengers
Advanced Healthcare Materials, EarlyView.Discrete mixed‐valent cerium molecular cages organize accessible redox centers within confined coordination environments and scavenge superoxide, hydrogen peroxide, and hydroxyl radicals. Encapsulation of the lead cage in an ROS‐responsive DTP nanoplatform enables lesion‐associated delivery, attenuates macrophage oxidative stress and inflammation, and ...
