Researchers have discovered a new way to grow graphene that deliberately adds structural defects to enhance its usefulness in electronics, sensors, catalysts, and more. Using a specially shaped molecule called azupyrene, scientists can produce graphene films rich in beneficial 5–7 ring defects—imperfections that make the material more interactive, more magnetic, and more electronically versatile.

Data source: Bloomberg L.P.
Note: Data through November 26, 2025. All crack spreads are calculated against the Dated Brent crude oil spot price.
Global refinery margins for diesel have widened since late October and increased to their highest level all year, following refinery outages in Russia and in the Middle East and new sanctions on Russia’s crude oil, leading to limited refinery production and a decreased global diesel supply. The impact was most pronounced in the Atlantic Basin, contributing to higher prices at the Amsterdam, Rotterdam, Antwerp (ARA) shipping hub, a key benchmark for European prices, as well as at New York Harbor and the U.S. Gulf Coast. The higher global prices also affected prices in the United States because U.S. refiners can sell into both domestic and international markets.
