High Shear Dispersion Techniques for Up‐Scaling and Controllable Cathode Morphology in High Performance Li−S Pouch Cells

open access: yesBatteries &Supercaps, EarlyView.
The effect of the blending procedure on the C−S suspension and therefore, on the Li−S battery performance is investigated. By comparing a common laboratory blender with a high shear mixing device, the higher shear forces result in a lower porosity and improved homogeneity of the electrode leading to enhanced cycle life, especially in multi‐layered ...

Analysis of squeezing‐induced failure in a water tunnel and measure of rehabilitation: A case study of Tishreen tunnel, Syria

open access: yesDeep Underground Science and Engineering, EarlyView.
Different failure modes observed in Tishreen tunnel include Floor heave, wall spalling, crashing of slab, and lining convergence reaching the failure limit. Abstract Squeezing phenomena can lead to severe loads in deep tunnels, especially in the presence of a low ratio of surrounding rock strength to overburden pressure.

Ground vibration isolation using mass scatters: A comparative study with trench barriers and wave‐impeding blocks

open access: yesDeep Underground Science and Engineering, EarlyView.
Ground‐borne vibrations are a frequent source of environmental problems. A full‐scale experiment is conducted to validate a 3D numerical model in order to analyze the efficiency of three methods of isolation. Trench barriers and wave‐impeding blocks are impractical and expensive methods of isolation, but mass scatters appear to be an efficient ...
