BNL team uses nc-AFM to find sulfur and nitrogen atoms in crude oil molecules

Green Car Congress

Researchers from the Center for Functional Nanomaterials at Brookhaven National Laboratory and users from ExxonMobil have developed a new approach to identifying atoms that are neither carbon nor hydrogen within a specific type of molecule in crude oil. Crude oil is one of the most complex molecule mixtures on the planet.

Achates near-zero heavy-duty opposed-piston diesel enters fleet service; compliant with 2027 NOx levels

Green Car Congress

The project team also demonstrated that the engine reduces carbon dioxide by 10%. The cleaner engine is able to deliver ultra-low NO x by managing exhaust gas temperatures to ensure rapid catalyst light-off and by maintaining aftertreatment temperatures at optimum operating conditions in all driving conditions.
