Oxide Interface of Gallium‐Based Liquid Metals: Beneficial Bridge or Hidden Risk?
ChemistryEurope, EarlyView.Discussion on oxide interfaces in gallium‐based liquid metals have concentrated on their properties, behaviors, and related applications. However, the molecular mechanisms underlying effects, as well as the differences between the presence and absence of the oxide layer, have been less thoroughly discussed.

Deep Underground Science and Engineering, EarlyView.Abstract One of the significant challenges faced in shield tunnel construction is the risk of collapse resulting from abrupt changes in soil conditions in advance of the working face, particularly within the sandy cobble stratum. This study aims to effectively manage these sudden variations and to further investigate the failure mechanisms associated ...

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

Automatic segment erection system for shield tunnels
Advanced Robotics, 1990 Shield tunnelling is now the practice most frequently used in the tunnelling of urban areas. This paper discusses an automatic segment erection system developed for the unmanned implementation of the shield method. The system is composed of a segment erection robot and an automatic segment feeder; the former assembles segments which prevent the ...
