Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

open access: yesDeep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Comparative Analysis of Metal Preloading Technologies in Batteries and Capacitors

open access: yesEcoEnergy, EarlyView.
Metal preloading strategies play an important role in efficient batteries and hybrid capacitors to compensate for the consumed metals at the first discharge. This article reviews recent progress in preloading technologies in lithium‐ion and other metal‐ion systems.

Synergistic Crystallinity Reduction and Lewis Acidic Promotion by PVDF‐Al(OH)3 for High Room‐Temperature Ionic Conductivity in PEO‐Based Composite Quasi‐Solid Electrolytes

open access: yesEcoEnergy, EarlyView.
Through the synergistic effects of crystallinity reduction and Lewis acidic promotion enabled by PVDF‐Al(OH)3, a PEO‐based composite quasi‐solid electrolyte has been developed, achieving both a high Li+ transfer number and superior ionic conductivity. It endows lithium metal batteries with excellent cycling stability at room temperature, even without ...

Review of the UK’s geological potential for the generation and accumulation of natural hydrogen [PDF]

open access: yes
Natural hydrogen is a naturally occurring gas, produced by a series of chemical reactions within rock formations, from where it migrates until it is trapped, typically in porous reservoirs beneath less permeable cap rocks.

Advances in Design Strategy and Mechanism Insights for Alkaline Hydrogen Evolution Reaction: Multilevel Site Engineering and Structure–Activity Relationship

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This review is about material design based on engineering multilevel sites from theoretical calculation and synthetic routes to mechanism, structure–activity relationship, challenges and perspectives for boosting hydrogen production in alkaline electrolyte. Electrolytic water splitting is a clean, carbon‐free method for producing green hydrogen and has

Quantitative Insights into Atomic Scale Oil–Clay Adhesion Governing Shale Oil Retention and Mobility

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Atomic force microscopy reveals a clear adhesion hierarchy between shale oil and clay minerals, governed by nanoscale surface chemistry. Strong interactions on chlorite and illite arise from abundant polar sites and cation bridging, whereas weaker coupling on montmorillonite limits interfacial binding.

Enabling Ultrastable Microbubbles With Graphene Aerogel Enrichment and Machine Learning for Highly Efficient Carbon Storage

open access: yesElectron, EarlyView.
This study aims to introduce a novel‐designed structure of the colloidal aphron microbubbles reinforced by incorporating hydrophobic aerographene microparticles onto the hydrophobic outer shell. This results in the formation of a robust composite film and armored microbubble that offers exceptional ultrastability under elevated pressures of up to 400 ...
