Single iron redox sites boost Methanol-SCR at low temperature
Nature CommunicationsSelective catalytic reduction of NOx to N2 by methanol as a reducing agent presents a prospective solution for the removal of NOx from the exhaust of methanol engines and the coal-fired power plant, but it confronts the problem of insufficient deNOx ...

Sensor-assisted Video Mapping of the Seafloor [PDF]
, 2002 In recent years video surveys have become an increasingly important ground-truthing of acousticseafloor characterization and benthic habitat mapping studies. However, the ground-truthing and detailed characterization provided by video are still typically

Quantifying microbial utilization of petroleum hydrocarbons in salt-marsh sediments using the ^(13)C content of bacterial rRNA [PDF]
, 2007 Natural remediation of oil spills is catalyzed by complex microbial consortia. Here we take a whole-community approach to investigate bacterial incorporation of petroleum hydrocarbons from a simulated oil spill.

Business Strategy and the Environment, Volume 35, Issue 4, Page 4961-4984, May 2026.ABSTRACT This study examines how carbon accounting can be used to govern, not merely report, circular economy principles in shipping corporations. Grounded in institutional theory and aligned with the UN 2030 Agenda, this study introduces circular harmony as an accounting design principle: Circular interventions are embedded in a single well‐to‐wake ...

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