Exploration of electrochemical behavior of Sb-based porous carbon composites anode for sodium-ion batteries.

Sb-based materials are considered as promising anode materials for sodium-ion batteries (SIBs) due to their excellent sodium storage capacities and suitable potentials. However, the Sb-based anodes usually suffer from intense volume expansion and severe pulverization during the alloying-dealloying process, resulting in poor cycling performance. Herein, a composite anode with Sb/SbO nanoparticles embedded in N-doped porous carbon is prepared by the gas-solid dual template method.

Effect of Post-Weld Annealing on Microstructure and Growth Behavior of Copper/Aluminum Friction Stir Welded Joint.

Friction stir welding of 1016 pure aluminum and T2 pure copper with 2 mm thickness was carried out in the form of lap welding of copper on the upper side and aluminum on the lower side. The growth of interface microstructure between 1016 pure aluminum and T2 pure copper welded by friction stir welding was studied. The growth mechanism of the intermetallic compound (IMC) layer in the Cu-Al lap joint was revealed by annealing at 300, 350, 400 °C.

Catalytic Gasification of Sewage Sludge in Supercritical Water: Influence of KCO and HO on Hydrogen Production and Phosphorus Yield.

In this work, the catalytic gasification of sewage sludge in supercritical water was investigated in a batch reactor (460 °C, 27 MPa, 6 min), and the separate and combined effects of the catalyst on the H production and phosphorus yield were investigated. The experimental results indicated that KCO alone improved the H yield, gasification efficiency (GE), and carbon gasification efficiency (CE). The largest H yield of 54.

Hydrogen production and phosphorus recovery via supercritical water gasification of sewage sludge in a batch reactor.

In this study, gasification of sewage sludge in supercritical water using a batch reactor was investigated. The effects of temperature, retention time, and the oxidation coefficient on gas composition, gas yield, total organic carbon removal efficiency (X), gasification efficiency (GE), carbon gasification efficiency (CE), and phosphorus release rate (X) were investigated. The experimental results indicated that the yields for hydrogen, methane, and carbon dioxide increased with the increase in temperature from 380 °C to 460 °C.
