One-step purification of C2H2 from ternary mixtures (C2H2, CO2, and CH4) can significantly reduce the energy consumption separation process, but it is extremely challenging. A new Co-MOF (TNU-BTTB-1) with a three-dimensional (3D) framework was synthesized, which displays high thermal stability, retaining its structural integrity at temperatures up to 400 °C. The structure possesses rich accessible open metal sites in porous walls shows uptake for (37.4 cm3 g–1) significant adsorption...

In this study, we utilize the advantages of offshore wind power resources in coastal areas to make up for shortage freshwater. At same time, freshwater can be used as raw material supply hydrogen energy. An operation strategy considering and water input an electrolyzer is proposed variable efficiency model under optimal mode also proposed. Considering both energy benefits maintenance costs, paper sets wind–hydrogen–water grid system model. Simulation analysis carried out from aspects...

Friction stir welding with different pin-eccentric tools (the pin eccentricities were 0, 0.4, and 0.8 mm, respectively) was successfully utilized for joining dissimilar aluminum alloys AA5052 AA6061, the influences of eccentricity on microstructural evolution mechanical properties joints investigated. The results showed that sound could be obtained by placing hard AA6061 in advancing side, while heat input led to both coarsening strengthening precipitates dynamic recrystallization softening...

Finally, pairing between potential-...

Performance of structured peer-to-peer overlay networks depends on the routing protocols. To get better speed with less scale table, using O (1) node finger to (N) route path, a new protocol named BCPP was presented. Structured by bidirectional circle topology, this p2p network has short table record one super node, successor previous and several cache nodes. Algorithms for maintaining distributed selection algorithm selecting were presented in paper. The neighbor nodes ensure high...

In article number 1800169 by Shulan Wang, Xuan Liu, Li and co-workers, Renewable plane tree fluff with a unique structure is used as biomass derived carbon source to synthesize hierarchical porous metal oxide/C photocatalysts trilevel pores ice silica templating. This nanocomposite the optimized parameters has excellent photo-electrochemical photocatalytic performance well high H2 evolution when loaded noble-metal-free carbide (Mo2C).

The performance of structured peer-to-peer overlay networks depends on the routing protocols mainly. current we used usually maintain a O(logN) table and hops. To get better speed with less scale table, using O(1) node finger to O(N) route path, new protocol named CSSP was presented. This has three layers: cache-nodes layer, super-node successor-node layer. A short made record L cache nodes, one super successor node. Algorithms for maintaining presented in this paper. selection algorithm...

The routing protocol of structured peer-to-peer overlay networks influences the p2p network performances in route table maintenance, hops, and churning. Current protocols we used usually maintain a O(logN) hops. To get better speed with less scale table, using O(1) node finger to O(N) path, new named CSSP was presented.
