U Birmingham study finds DPFs have limited impact on ultrafine particle emissions

Green Car Congress

A study by researchers at the University of Birmingham in the UK has found that while Diesel Oxidation Catalysts (DOCs) and Diesel Particle Filters (DPFs) has been very effective in controlling the tailpipe emissions of solid particles, there has been little change in the liquid mode ( 104 cm −3 /24-hour mean) defined by WHO. 2023.107888

Researchers develop method for producing boundary-free single crystals to improve NMC performance

Green Car Congress

Image shows single crystals of cathode material: (A) no internal boundaries and (B) internal boundaries visible. By contrast, over the same cycle life, the capacity declined by 60% to 88% in NMC cathodes composed of single crystals with many internal boundaries or with coated polycrystals.
