From Molecules to Modules: Advanced Characterization of Membrane Systems

open access: yesAdvanced Materials, EarlyView.
Membrane technologies can enhance the efficiency and selectivity of chemical separations in energy‐water systems. Improving our understanding and design of separation membranes will require studying their properties at the molecular scale, mesoscale, and macroscale. This perspective highlights advanced characterization techniques for revealing membrane

Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

open access: yesAdvanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.
