Abstract: At present, the method of model testing is rarely used to study the low-frequency vibration problems of bridge structures, because it is difficult to keep the similarity between the bridge model and the prototype in model ...

Abstract: Three different MnO2 polymorphs, α-MnO2, β-MnO2, and δ-MnO2, with K+-tuned tunnel structures were loaded on sludge-based biochar (BC). Then MnO2-loaded BCs served as the catalyst for ciprofloxacin (CIP) removal. Results ...
