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,...

Open AccessIdentifying defect-related quantum emitters in monolayer WSe2
Monolayer transition metal dichalcogenides have recently attracted great interests because the quantum dots embedded in monolayer can serve as optically active single-photon emitters. Here, we provide an inter...

Three-dimensional ordered hollow sphere composite Pt/TiO2-ZrO2: enhanced performance of photocatalytic degradation and photocatalytic hydrogen evolution
In this paper, a three-dimensional ordered hollow sphere (3DOH) structure composite Pt/TiO2-ZrO2 was prepared by using polystyrene (PS) colloidal spheres as the template and combining with two-step vacuum impregn...
