Startup Mattershift says it has achieved a breakthrough in making carbon nanotube (CNT) membranes at large scale. The startup is developing the technology’s ability to combine and separate individual molecules to make gasoline, diesel, and jet fuel using CO2 removed from the air. In an open-access paper in Science Advances, researchers from Mattershift and colleagues in the labs of Dr. Benny Freeman at The University of Texas at Austin and Dr. Jeffrey McCutcheon at the University of Connecticut confirmed that Mattershift’s large-scale CNT membranes match the characteristics and performance of small prototype CNT membranes previously reported on in the scientific literature.
