Denitrification process is a crucial step in nitrogen removal and is more vulnerable to external shocks due to the fact that anoxic process is always located before aerobic process in conventional sewage treatment. This study aims to elaborate the nitrogen conversion characteristics by...

Constructing acceptor–donor units (D/A) of polymer is an efficient method for promoting carrier separation to optimize photoreactivity. However, the carriers across the D/A interface of micromolecule was relatively hindered by the Coulomb potential. In this work, the polarity-bridged...

Modern trams usually own passive transit signal priority (TSP) to avoid interruption from traffic signals along the route. The key to TSP depends on the strictly stick to the recommend travel time between intersections. However, the effectiveness of the TSP can be weakened by dwell time...

Inorganic lead-free Cs 2 AgBiBr 6 double perovskite is a promising material for solving the toxicity and the instability of organic-inorganic hybrid perovskite. However, due to the poor interface contact and inferior perovskite film quality, the open-circuit voltage and the power conversion...
