Numerical simulation study on the characteristics and propagation attenuation of vibration signals in freezing pipe fracture

open access: yesDeep Underground Science and Engineering, EarlyView.
This research study employs analysis system (ANSYS) fluid–structure interaction simulations to investigate the generation and attenuation of vibration signals resulting from freezing pipe fractures in artificial ground freezing projects. By evaluating key variables—including frozen soil elastic modulus, brine inlet pressure, and external pipe pressure ...

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.

Synergistic Molecular Engineering and Crosslinking Topology for High‐Temperature Energy Storage in All‐Organic Dielectrics

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A synergistic strategy combining CF3 group incorporation and crosslinking topology is employed to tailor chain spacing and local ordering in all‐organic dielectrics. This design effectively suppresses carrier migration and enhances polarization, yielding outstanding high‐temperature energy storage performance (e.g., 8.95 J cm−3 with 90% efficiency at ...

The Serendipitous Discovery of Rollover Cyclometalation: From Unrecognized Observation to Transformative Chemistry

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Rollover cyclometalation is a distinctive variant of classical cyclometalation where a chelated heterocyclic ligand undergoes internal rotation, releasing one donor atom from coordination and subsequently activating a remote C─H bond with high regioselectivity.

Influence of 6‐Trifluoromethyluracil Versus Chloride Counterions in the Properties of Bis‐(1,10‐Phenanthroline)chloridecopper(II) Motif: Spectroscopic and In Vitro Biological Activity Assays

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
This work explores the influence of 6‐trifluoromethyluracil versus chloride counterions on the antibacterial and antitumoral activities of bis‐(1,10‐phenanthroline)chloridecopper(II) motif. The counterion modulates antibacterial potency and the identity of the dominant reactive species, while leaving DNA recognition by the shared cation essentially ...

A Parametric Computational Framework for Modeling and Seismic Design of Post‐Tensioned Mass Timber Rocking Walls

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Post‐tensioned cross‐laminated timber (PT‐CLT) rocking walls offer a compelling seismic system combining self‐centering behavior with energy dissipation. However, progress in their performance assessment and design has been limited by the lack of a comprehensive parametric modeling tool, as exists for steel or reinforced concrete systems. This
