Excited to share our latest Ind. Eng. Chem. Res. publication! 🎉 Led by Mario Zorrilla-Valtierra (Lively lab @GTChBE and @walton_lab currently @NCState), this work investigates the stability of amine-functionalized MOFs for direct air capture under exposure to ozone and NOx impurities generated from air. Understanding how these contaminants affect CO2 capture performance and material structure is an important step toward designing more durable DAC sorbents for real-world operation.

Excited to share our latest Nature Chemical Engineering publication! 🎉 Led by @Sarswat_Akriti (Lively & Sholl groups, @GTChBE, currently a postdoctoral researcher in @Princeton Hatzell group), this work establishes product concentration benchmarks for tandem electrochemical CO2-to-ethylene conversion. By integrating reaction engineering, separations, and techno-economic analysis, we identify the product concentrations needed to make electrochemical C2H4 production commercially viable, providing practical design targets for next-generation CO2 conversion systems. 👉Read more: doi.org/10.1038/s44286-026-0… #CO2Electrolysis #CarbonUtilization #ChemicalEngineering

🎉The latest Nature publication, led by Jihoon Choi and Hyukjoon Seo (KAIST) with collaborators at @GTChBE, demonstrates a membrane-based crude oil pre-fractionation strategy that could transform oil refining. Remarkably, the porous PAN support spontaneously forms a molecular sieve during operation, enabling room-temperature separation before distillation. This approach could reduce refinery energy use by 31.6%, CO2 emissions by 37.6%, and operating costs by 36%, marking a major step toward more sustainable chemical separations.

Crude oil refining hasn't changed much in a century. Researchers at Georgia Tech and KAIST have published a paper in Nature that suggests a simple membrane material could significantly cut the energy and carbon footprint of petroleum refining. b.gatech.edu/3R4vqc5

🎉 Worth highlighting: In our latest Journal of Membrane Science publication, led by @inyoung5511 and @Haoyu_Chen_ (@GTChBE, Lively Lab), we reveal that CO2 can diffuse uphill across membranes when driven by the chemical potential difference of H2O.

Excited to highlight our latest work!🎉 In our latest J. Membr. Sci. publication led by Woo Jin Jang (Lively group, @GTChBE), we report uphill transport of phenolics in bio-oil mixtures via "sorpvection", where methanol flux drives guaiacol enrichment across DUCKY-9 membranes.

Another good news to share! 🎉 In our latest J. Membr. Sci. publication led by Young Joo Lee (Lively group, @GTChBE), we combine machine learning with transport modeling to screen microporous polymers for organic solvent reverse osmosis. Prediction-assisted selection enabled identification of a high-performing TB-based ladder polymer (POLYMER-4), showing strong separation of aromatic hydrocarbons! A promising direction for data-driven membrane design. 👉sciencedirect.com/science/ar… #MembraneScience #MachineLearning #PolymerMembranes #Sustainability

🎉Excited to share that in our latest Energy Environ. Sci. paper led by Seo-Yul Kim (Lively group, @GTChBE), we propose a new concept: near-cryogenic direct air capture (DAC) using physisorbents like Zeolite 13X and CALF-20, thermally coupled with LNG regasification. This approach cuts DAC energy demand to as low as 1.7-3.3 GJ/tCO₂ and slashes the levelized cost of capture by ~60%, opening a scalable, low-cost path for gigaton-scale carbon removal.
