Synthesis of Hydrocarbon Fuels From Dimethyl Ether Through Co‐Oligomerization of Olefins

open access: yesChemie Ingenieur Technik, Volume 98, Issue 5, Page 262-270, May 2026.
This work investigates the impact of higher olefins and typical impurities from a preceding Dimethyl ether‐to‐Olefins (DtO) process on olefin oligomerization for sustainable fuel production. Several key properties of the kerosene fraction comply with the ASTM D7566 22a standard for sustainable aviation fuels, whereas some important properties of the ...

From Rainfall to Rumors: Interpreting the 2024 Bangladesh Floods Through Numbers, Narratives, and Information Gaps

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract When severe floods struck southeastern Bangladesh in August 2024, competing explanations emerged. Meteorological analysis revealed that extreme precipitation was exacerbated by the Madden‐Julian Oscillation and jet stream dynamics. However, alternative narratives proliferated on social media, particularly claims that India deliberately ...
