A novel kind of miniature boat that might have many potential applications was fabricated from superhydrophobic copper meshes for the first time. These boats not only floated freely on a water surface but also exhibited striking loading capacities. By selection pore size meshes, capacity greater than 11.0 g could be readily achieved 8.0 cm3 in volume. The large is believed to arise air film surrounding surfaces boats. results this study present new artificial areas aquatic devices.
For most electrodes fabricated with carbon, transition metal compounds, or conductive polymers, the capacitance may deteriorate cyclic charging and discharging. Thus, an electrochemically stable supercapacitor has long been pursued by researchers. In this work, hierarchical structure of balsa wood is preserved in converted carbon which used as a supporting framework to fabricate for supercapacitors. Well-grown nanotubes (CNTs) on interior exterior surfaces channels provide two advantages...
Transition metal silicates (TMSs) are potential electrodes for aqueous metal-ion intercalation pseudocapacitors owing to their superior theoretical capacity and high structural stability. However, the narrow interlayer spacing intrinsic inert basal plane of TMSs lead sluggish ions charge transfer, causing an undesirable energy storage performance. Herein, rich Mn vacancies introduced in layered manganous (M
Reactive force field molecular dynamics (ReaxFF-MD) (reactive dynamics) is a promising method for exploring complex chemical reactions, allowing better understanding of sulfur transformation during coal pyrolysis. In this work, we built three pyrolysis systems with different H2O contents to explore the effect on demineralized by ReaxFF-MD. Product distributions, sulfur-containing bonds, and path organic in were analyzed. We found that could accelerate process, reduce semicoke yield, increase...

Furthermore, AVIRIS Landsat 7 images collected over spill accident Gulf Mexico used demonstrate feasibility apply experimental results identification...
Linear plasma devices are the ideal to simulate divertor conditions of tokamak experimentally. The Multiple Plasma Simulation Device (MPS-LD) is under construction at Dalian University Technology with a focus studying plasma-material interactions (PMIs) and edge transport.
