Boosting Sodium Storage Activity and Kinetics of Hard Carbon by Remodeling Oxygen Chemistry

Carbon Energy, EarlyView.
A surface oxygen remodeling strategy is proposed to finely furnish the pseudographitic structure of hard carbon with rich closed pores and expanded interlayer spacings. Accordingly, the sodiation reactivity and kinetics are greatly reinforced to afford an elevated capacity of 360 mAh g−1 and outstanding rate capability of 225 mAh g−1 at 2 A g−1 ...

Unexpected Arsenic Compounds in Low-Rank Coals

Environmental Science & Technology, 2005
Nine low-rank coal samples from three different coal basins (Velenje and Trbovlje basins, Slovenia, and Sokolov basin, Czech Republic) were analyzed for their elemental composition and the presence of arsenic compounds. Total arsenic concentrations in the samples were 1.59-5.77 microg g(-1) with one exception, 142 microg g(-1) for a sample from the ...
