The preparation of bimetallic cerium/copper organic framework-derived CeCuOx/C NH3-SCR catalysts
The bimetallic Ce/Cu-MOF was synthesized by the room temperature hydrothermal method, and then the CeCuOx/C catalyst was obtained by in-situ pyrolysis method under nitrogen atmosphere. Moreover, their catalytic p...

Superbroad-band actively tunable acoustic metamaterials driven from poly (ethylene terephthalate)/Carbon nanotube nanocomposite membranes
Actively tunable acoustic metamaterials have attracted ever increasing attention. However, their tunable frequency range is quite narrow (tens of Hz) even under ultrahigh applied voltage (about 1,000 V). Here,...

Wetting and reaction of molten La with poly- and mono-crystalline MgO at 1323 K
Wetting of poly- and mono-crystalline MgO substrates by molten La was investigated at 1323 K in a high vacuum using a modified sessile drop method. The wettability seems to depend mildly on the substrate orien...
