Investigation on hard‐rock breaking performance and auxiliary mechanism of picks assisted with both‐sided high‐pressure water jets

open access: yesDeep Underground Science and Engineering, EarlyView.
This paper investigates the high‐pressure water jet‐pick combined rock‐breaking mode (HPC), which employs high‐pressure water jets to precut grooves on both sides of the picks. The rock‐breaking patterns and performance of the HPC method are obtained, and the auxiliary rock‐breaking mechanism of water jet grooving is revealed.

Regulating the Conversion Efficiency and Kinetics of Halogen‐Based Reactions for High‐Performance Aqueous Zn Batteries

open access: yesEcoEnergy, EarlyView.
Herein, we focus on the recent progress, energy storage mechanisms, and design strategies for aqueous zinc‐halogen batteries (AZHBs). Specifically, we explored the understanding of thermodynamics and kinetics challenges of Zn‐I2, Zn‐Br2, and Zn‐Cl2 batteries in depth.

Enhanced Hydrogen Evolution Reaction Performance of Ni‐Doped MoS2 with 1T Structure for Alkaline Water Electrolyzer: Introduction of 1T Phase and Morphological Optimization Through Co‐Sputtering Technique

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The hydrogen evolution reaction activity of Ni‐doped MoS2 is enhanced by optimizing sputtering parameters in co‐sputtering. Sputtering power controls morphology and Ni doping which promotes 1T yield and activates basal planes. Sputtering time changes 1T yield regardless of Ni ratio.
