Ion Superhighways in a Hierarchical Polymer‐Ceramic Membrane Enable Rapid and Selective Lithium Extraction

Xinxin Wei, Jiawei Sun, Min Wei Boey, X Li et autres

ABSTRACT Lithium recovery from complex brines is a key challenge for the clean energy transition. Conventional polymer membranes lack selectivity, while highly selective ceramic solid electrolytes are brittle and difficult to scale. Here we address this gap by creating a flexible polymer‐ceramic …

Green and blue methanol: Biomass or DAC carbon combined with SMR and Allam–Fetvedt cycle

Junghwan Kim, Junsu Kim, Matthew J. Realff

Low-carbon methanol production faces a trade-off between cost and depth of decarbonization. This study compares four small modular reactor (SMR)-assisted methanol pathways at 100 kt MeOH/yr: biomass with the Allam–Fetvedt cycle (Case 1), biomass only (Case 2), direct air capture (DAC) with …

Biopolymer-Induced Nanoarchitectured Superhydrophilic Carbon Aerogel with Efficient Transport Channel for Sustainable Water Purification

Dongha Lee, Jieun Jang, Donggyun Kim, Seonghyeon Jung et autres

Global freshwater scarcity is driving the search for alternative aqua purification strategies. Solar-driven desalination has emerged as a leading solution, leveraging the abundance of seawater and salt lakes on Earth. In this study, we present an advanced interfacial solar-driven nanocarbon aerogel derived …
