Temperature‐dependent shear behavior and constitutive model of the rock–concrete interface

open access: yesDeep Underground Science and Engineering, EarlyView.
Shear tests were conducted to investigate the temperature‐dependent shear behavior of the rock–concrete interface, highlighting the interaction between the surrounding rock and the lining during tunnel fires. Under experimental conditions, concrete exhibited greater temperature sensitivity than rock, with the shear fracture surface transitioning from ...

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.

Gradient‐Engineered Ultra‐Thin Lithium Metal Anodes with a Li–Si–N Alloy‐Based Lithiophilic Current Collector Interphase

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel strategy for fabricating ultra‐thin lithiophilic Li metal anodes for high energy density Li metal batteries is proposed. This anode features a one‐step phase‐transition process, consisting of LixSiy with high mechanical strength and LixNy with excellent ionic conductivity.
