Study shows biodiesel blends in buses reduce PM, other harmful exhaust elements, EC and CO

Green Car Congress

Before they can be used, however, it is essential to understand their physical properties, combustion chemistry, and characterization of the exhaust due to a number of issues associated with fuel properties—for example, a lower heating value and higher cloud point than regular diesel.

Researchers devise method to suppress thermal conductivity to improve thermoelectric materials for waste heat recovery

Green Car Congress

A new study published in the journal Nature Materials has found a way to suppress the thermal conductivity in sodium cobaltate so that it can be used to harvest waste energy, with potential applications such as automotive waste heat recovery. Resources. CoO 2 , which has a large-period superstructure. —Voneshen et al. Piovano, E.

Haldor Topsøe ECO-Jet wins award; reducing soot, HC and heavy metal emissions from ships powered by bunker fuel

Green Car Congress

Particulate filter systems are developed for diesel engine exhaust with a relatively low sulfur and ash content. The ECO-Jet process also removes other harmful substances from the exhaust of engines using bunker fuel, for instance poisonous hydrocarbons and metals including vanadium, iron, nickel, silicon and sodium.

Drexel researchers demonstrate intercalation of MXenes with a variety of ions; high volumetric capacitance

Green Car Congress

Currently, eight MXenes have been reported by our team, but there are likely many more that will be discovered—the MXene-and-ion combinations that have been tested to date are by no means an exhaustive demonstration of the material’s energy storage capabilities. —Yury Gogotsi. Lukatskaya, Olha Mashtalir, Chang E.
