Decoupling Thermodynamic and Kinetic Moisture Instability Reveals a Critical Humidity Threshold for Sodium Thiophosphate Solid Electrolyte

Advanced Energy Materials, EarlyView.
A quantitative exposure‐heat treatment framework identifies a critical humidity threshold (15%RH) and heat treatment temperature (80°C) that governs the recoverability of air‐exposed Na3PS4, revealing the decoupled thermodynamic and kinetic contributions to its moisture stability.

Structured sorbents for Direct Air Capture: The impact of materials and chemicals on performance

AIChE Journal, EarlyView.
Abstract Structured sorbents can efficiently process large air volumes required for Direct Air Capture (DAC), but their broad implementation is limited by challenges in producing reproducible and homogeneous materials. This work presents a robust procedure to graft amines onto monolithic sorbents and systematically investigates how CO2$$ {\mathrm{CO ...
