In battery electric vehicles the efficiency of the powertrain has a big impact on driving range and performance. As the overall efficiency of the electric powertrain is typically more than 90%, ...

When experiments are impractical, density functional theory (DFT) calculations can give researchers accurate approximations of chemical properties. The mathematical equations that underpin the ...

A method has been developed that allows direct, accurate calculation of recovery efficiency for Claus sulfur-recovery units (SRU). The calculation combines feed-gas data and tail-gas composition to ...
