This article studies the energy management of distribution-level integrated electric-gas systems (D-IEGSs), considering their frequency support capability via providing the fast frequency reserve (FFR ...

Doping and constructing heterojunctions have been demonstrated to be effective for improving the catalytic activity of titanium dioxide (TiO2); however, better performance is still widely expected for ...

Nitrogen finally joins the elite tier of elements like carbon that can form neutral allotropes—different structural forms of a single chemical element. Researchers from Justus Liebig University ...
