Stress wave attenuation by roof-cutting pre-splitting in deep coal mine roadways: Mechanism and experimental validation

International Journal of Mining Science and Technology
Dynamic disasters induced by rock mass instability under deep mining conditions constitute a major geotechnical challenge, particularly in coal mine roadways excavated beneath ultra-thick hard roofs.

Varying Shear Wave Splitting Parameters Suggest Interaction Between Lithosphere and Asthenosphere in Arxan‐Chaihe Volcanic Field, NE China

Geophysical Research Letters, 2022
Over 2 years of broadband seismic data from 27 temporary stations deployed in the Arxan‐Chaihe Volcanic Field (ACVF) provides us a valued opportunity to study mantle deformation and related geodynamic processes in NE China intraplate region. We estimated

TiO6 as a Compensatory Structural Unit in Co‐Free, High‐Ni Layered Oxide for Durable Lithium‐Ion Batteries

Advanced Science, EarlyView.
Ti substitution stabilizes Co‐free high‐Ni layered oxides through both structural and electronic effects. TiO6 octahedra act as compensatory structural units that help interrupt cooperative Jahn–Teller distortion and suppress detrimental phase transitions, while the electron‐withdrawing inductive effect of Ti stabilizes the oxygen lattice. As a result,

Anisotropy and mantle flow of the Indo-Burma subduction zone from shear wave splitting and shear wave splitting tomography

, 2023
The Indo-Burma subduction zone lies on the eastern boundary of the 1500 km long Alpine-Himalayan orogenic belt. Despite highly oblique plate motion with limited arc development, convergence is still ongoing with the potential to generate megathrust earthquakes that could affect more than 140 million people. This sub-aerial subduction system provides an

Controlled Lattice Distortion and Lattice‐Strain‐Engineered CoCuIr Alloy toward Preferential Chlorine Tolerant Direct Seawater Electrolysis

Advanced Science, EarlyView.
A lattice‐strain‐engineered Co0.28Cu0.67Ir0.05 trimetallic alloy nanoparticle electrocatalyst is rationally designed for efficient alkaline seawater electrolysis. Larger Ir atoms in the CoCu lattice modulate the local coordination environment, generating compressive lattice strain and highly active catalytic sites.

Shear‐wave splitting in the Rio Grande Rift

Geophysical Research Letters, 1992
Fast directions and lag times associated with SKS shear‐wave splitting are determined for six digital stations in the Rio Grande Rift (RGR). The mean fast direction for three stations in the central RGR is about 45° oblique to the axis of the RGR. In contrast, fast directions approximately parallel to the axis of the RGR are found for two stations in ...

Magnetically Guided Macrophage Immunobots Coordinate Iron‐Metabolic Cascades and Immunogenic Ferroptosis for Tumor Immunotherapy

Advanced Science, EarlyView.
Magnetically guided macrophage immunobots integrate active tumor targeting with immunometabolic therapy. After systemic administration, magnetic actuation enhances immunobot retention and tumor penetration, while LPS‐functionalized FePt microrollers sustain M1‐like polarization through inflammatory and iron‐amplified oxidative signaling and trigger ...

Evaluation of liver stiffness measurement–based scores in liver transplantation recipients

Liver Transplantation, EarlyView., 2022
Abstract Combining bioclinical parameters with liver stiffness measurement (LSM) has improved the diagnostic performance of vibration‐controlled transient elastography (VCTE) for detection of advanced fibrosis in patients with chronic liver disease. However, this approach has not yet been tested in liver transplantation (LT) recipients.

Density structure of Earth’s lowermost mantle from Stoneley mode splitting observations

Nature Communications, 2017
Large-low-shear-wave velocity provinces (LLSVPs) are present at the core–mantle boundary. Here, the authors show that splitting of Stoneley modes is probably due to a lower density of LLSVPs than the surrounding mantle because of the presence of post ...
