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 ...

Major engineering breakthrough of Well XA‐1, the deepest ten‐thousand‐meter well in a global sedimentary basin

open access: yesDeep Underground Science and Engineering, EarlyView.
Well XA‐1, completed at a true vertical depth of 11 156 m in the Shawan Sag of the Junggar Basin, is the deepest predominantly near‐vertical well drilled in a sedimentary basin. The figure shows the basin's tectonic framework and well location (a), a structural cross‐section spanning the Shawan Sag and adjacent uplifts (b), and the stratigraphic column

Magnetic Electrocatalysts Enabling a High‐Rate Capability in Lithium‐Oxygen Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces zinc ferrite (ZnFe2O4) nanoparticles with tunable magnetic properties as bifunctional electrocatalysts for lithium‐oxygen batteries. Under an applied magnetic field, these catalysts significantly enhance oxygen reduction and evolution reactions by promoting spin‐aligned charge transfer and ion diffusion. The approach achieves high

Synthesis, Structure, and Lewis Acidity of Heavy Pnictenium Cations

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
A series of donor‐coordinated and donor‐free heavy pnictenium cations were synthesized and structurally characterized. The cations are strong Lewis acids according to experimental (Gutmann–Beckett method) and computational studies (FIAs). Strained pnictanes L1PnNaph (Pn = Sb 1, Bi 2; L1 = 2,6‐(2,4,6‐i‐Pr3C6H2)2C6H3) were synthesized and protonation ...

Operational and environmental barriers to centralized composting in two small Brazilian municipalities: A longitudinal study

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Municipal solid waste management in small cities faces severe logistical and financial barriers regarding organic fraction treatment. This study evaluates biological selective collection in two small Brazilian municipalities (Astorga and Sabáudia), comparing dynamics between gated communities (GC) and public thoroughfares (PT) over an annual ...

Reflex seizures and epilepsy surgery: A network approach case‐based exploration

open access: yesEpileptic Disorders, EarlyView.
Abstract Context Reflex seizures (RS) are defined by their consistent provocation by specific stimuli, encompassing a broad range from elementary sensory inputs to complex cognitive tasks. While RS are often encountered in clinical practice, their surgical management remains sparsely reported and poorly systematized.
