Radiation‐Resistant Kr‐Selective MOF With Record Kr/Xe Selectivity at Elevated Pressure

Advanced Science, Volume 13, Issue 41, 22 July 2026.
ABSTRACT The separation of Kr/Xe from spent nuclear fuel off‐gas is critical, yet most current adsorbents exhibit Xe‐Kr co‐adsorption under elevated pressures, posing challenges for industrial pressure swing adsorption processes. Herein, we present and evaluate a metal‐organic framework, CALF‐20M‐w, engineered for molecular sieving separation of Kr/Xe ...

Evaluating direct use fertilizer potential of hydrothermal liquefaction solid mineral products: Integrating anaerobic digestion and hydrothermal liquefaction

Waste Management
Sustainable agriculture is vital for reducing reliance on harmful chemical fertilizers and ensuring environmental and economic stability. Integrating Hydrothermal Liquefaction (HTL) with anaerobic digestion (AD) can improve biomass efficiency and recovery of both energy (liquid fuels) and valuable nutrients, essential for achieving circular bioeconomy.
