Cascading marginal emissions signals for green charging with growing electric vehicle adoption [PDF]
Shifting electric vehicle charging to use cleaner electricity can reduce carbon dioxide emissions. Grid emissions factors can inform when to shift demand, but key assumptions behind existing emissions factor methods fail for today’s grids and electric ...

Heavy-duty vehicle emission characteristics based on the remote-monitoring three-bin moving-average window method [PDF]
A three-bin moving average window (3B-MAW) model was proposed and compared with the work-based window method (WB-WM) to investigate the on-road emission characteristics of heavy-duty vehicles. The invalid data of remote monitoring were mainly composed of

Alcohol consumption promotes arsenic absorption but reduces tissue arsenic accumulation in mice
Alcohol consumption alters gut microflora and damages intestinal tight junction barriers, which may affect arsenic (As) oral bioavailability. In this study, mice were exposed to arsenate in the diet (6 μg/g) over a 3-week period and gavaged daily with ...

The enhancement effect of Nb over CeSi2 catalyst for the low-temperature NH3-SCR performance
Tuning the acid site on the surface of the catalyst tends towards facilitating the selective reduction of NOx by NH3 (NH3-SCR). In this study, a set of catalysts for the Nb/CeSi2 with different loadings of niobium were synthesized and evaluated in terms ...
