Cu‐Co Oxide/Carbon Composites Modified by DBD Plasma for Flexible Zn‐Air Battery Cathodes

Carbon and Hydrogen, EarlyView.
A Cu3‐Co1/AC‐DBD composite catalyst was prepared using a “stepwise synthesis plasma synergistic modification” strategy, which exhibits excellent bifunctional catalytic activity. ABSTRACT This study is aimed at the demand for high‐performance energy storage systems in flexible wearable electronic devices, focusing on the development of cathode catalysts

Energy Balancing of Electrochemical Alternatives to the Solvay Process

Chemie Ingenieur Technik, EarlyView.
To overcome the CaCl2 and CO2 emissions custom to the conventional Solvay process in soda ash production, electrochemically based alternatives were investigated. In particular, the mass‐ and energy balances for chlor‐alkali electrolysis and bipolar electrodialysis‐based processes are discussed comprehensively in the presented work.

Failure mechanism of the coal wall at the working face based on an eccentric compression mechanical model

Deep Underground Science and Engineering, EarlyView.
In this study, the nonuniform distribution of the bearing pressure in front of the coal wall has been revealed based on in situ monitoring data and numerical simulation results. Therefore, an eccentric compression mechanical model of the coal wall was established to study the deformation and failure characteristics of a coal wall. The slenderness ratio

Combustion of pipelineable coal-water slurries

, 1991
The use of liquids or fluids to transport coal through pipelines is not new, nor is the application of coal liquid slurries as fuels in industrial combustion systems. However, it does appear that there are a number of conflicting areas which preclude coals from performing well in a pipeline transportation mode and as a coal-liquid fuel (CLF).

Nonsilting transport characteristics of coal slurry in a deep underground fluidization conveying pipeline under the action of a guide vane swirler

Deep Underground Science and Engineering, EarlyView.
Aiming at the scientific frontiers of in situ fluidized mining of deep resources, a deep coal fluidized pipeline lifting system based on hydraulic conveying has been proposed. To solve the issue of particle sedimentation of large particles in horizontal connection sections, a solution involving the installation of guide vane‐type swirlers in the ...
