Tianjin Team's COF Membrane Hits Record CO2 Permeability at $38/t

Tianjin – October 13, 2026 -- Researchers at Tianjin University have developed an all-organic mixed-matrix membrane that raised CO2 permeability by an order of magnitude in simulated flue gas tests, a new record, with a preliminary capture cost estimate of about $38 per tonne of CO2.

The study appeared online in Nature Energy on Oct. 7 under the title "All-organic mixed-matrix membranes with single-crystal covalent organic frameworks for carbon capture."

Weak-interaction inlaying targets the filler-polymer compatibility problem

Mixed-matrix membranes pair the processability of polymers with the molecular transport of porous fillers. Development has been limited by compatibility problems between the two components. Porous particles can aggregate or settle within the polymer. Overly strong filler-polymer interactions can restrict polymer movement or block transport pathways.

NTT Cuts Microalgae CO2 Measurement Error From 3,300% to 8%

NTT Cuts Microalgae CO2 Measurement Error From 3,300% to 8%

Tokyo – October 12, 2026 -- NTT, Inc. has cut the maximum relative error of sensor-based CO2 absorption monitoring in microalgae cultures from approximately 3,300% to approximately 8%, measured against the conventional titration method.

The technology calculates dissolved inorganic carbon (DIC) concentrations from CO2 and other sensor readings. It does not require sampling the culture fluid for each measurement. The results were published in the journal Algal Research on August 12, 2026.

Titration is accurate but cannot deliver continuous data

Evaluating microalgal CO2 absorption means tracking DIC, which exists in culture fluid as dissolved CO2, bicarbonate ions and carbonate ions. Titration measures DIC accurately, but every reading requires a fluid sample and takes time and effort, so it does not suit continuous data acquisition.
