Numerical and experimental study on P‐wave propagation across a rock joint with different orientations

open access: yesDeep Underground Science and Engineering, EarlyView.
Joint orientation significantly affects P‐wave velocity, with the highest velocity at zero‐degree angles, decreasing to 30° as the angle increases. The velocity increases slightly from 30 to 45 degrees but sharply decreases from 45 to 90 degrees. Abstract Determination of the required parameters in different science contexts using the ultrasonic wave ...

Developing a universal tunnel span classification from global tunnel databases

open access: yesDeep Underground Science and Engineering, EarlyView.
A universal tunnel span classification system is introduced that incorporates tunnel span, cross‐sectional area, typical tunnel types, and intended uses. Representative flatness ratio values are also provided for each span class. The classification is derived from a comprehensive database of 450 tunnel profiles from 47 countries.

Modifiable Transdiagnostic Risk and Protective Factors as Potential CBT Augmentation Targets for Eating Disorders: An Updated Umbrella Review

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective A focus on transdiagnostic targets is one of the key strategies for developing effective, efficient, and scalable treatments for mental health conditions. We conducted an umbrella review of recent meta‐analyses (August 2022 to May 2026) to update our understanding of critical transdiagnostic intervention targets that could inform ...

Electrolytic (C2CNT) Carbon Nanotubes Made From CO2 as an Inexpensive Carbon Sink and High‐Capacity Li‐Ion Battery Graphite Replacement

open access: yesEcoEnergy, EarlyView.
Carbon‐negative carbon nanotubes produced by molten CO2 electrolysis offer a low‐cost, high‐performance alternative to graphite in Li‐ion battery anodes. Replacing conventional carbon materials with electrolytic CNTs can improve battery capacity and charging performance while reducing costs and contributing to carbon mitigation.

Metal‐Free Halogen‐Engineered Carbon Nanotubes for Highly Efficient Oxygen Reduction Reaction

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In work employs density functional theory screening to guide the halogen engineering of metal‐free, Cl‐mediated carbon nanotubes for a highly efficient oxygen reduction reaction (ORR). Cl‐mediation optimally tunes the electronic structure and binding energies of oxygen intermediates, delivering an ORR activity rivaling that of commercial Pt/C, high 4e−
