New sustainable materials from recycled carbon nanotubes
Recycling materials, such as plastics and metals, is an attractive, but challenging path toward sustainable material manufacture. Now, researchers have made a discovery that may have far-reaching implications in material manufacture by positioning carbon nanotube (CNT) fibers as a sustainable…
Carbon-neutral calcium carbonate process uses emissions from steel-making plant
Construction is imminent for a carbon-capture project aimed at reducing CO2 emissions from steel production while producing carbon-neutral calcium carbonate. At the U.S. Steel (Pittsburgh, Pa.; www.ussteel.com) manufacturing facility in Gary, Ind., a carbon-capture system designed by CarbonFree (San Antonio,…
Creating ultrathin gold films with the largest continuous area
Thin gold films offer a broad range of benefits for electronics due to their high electrical conductivity and transparency. Current manufacturing methods are unable to achieve gold films thinner than 10 nm, and are also limited in the area and…
Flow chemistry yields a more sustainable route to isocyanates
The wide range of performance properties of polyurethane foams makes them essential in many consumer goods. Thus, there is much effort going into creating a more environmentally friendly production process for polyurethane’s main building blocks, polyols and isocyanates. While much…
Pilot project planned for thermocatalytic ethanol-to-butene process
In December 2024, the Pacific Northwest National Laboratory (PNNL; Richland, Wash.; www.pnnl.gov) announced a three-year collaborative project with vehicle-tire manufacturer Bridgestone (Tokyo, Japan; www.bridgestone.com) to scale up a thermocatalytic process for converting renewably derived ethanol to n-butene. Conventionally, n-butene is…
Quality Control: The Simple but Crucial Details for Safer Manufacturing
Quality control processes can have a reputation for being redundant or tedious, but they play a fundamental role in producing consistent and effective products. When it comes to the manufacturing of products for the medical and life-sciences sectors, these processes…
