Features of Stress State Reconstruction in Carbonate Rocks on the Example of an Oil Field of the Republic of Tatarstan

Georesources
   The paper presents the results of laboratory studies of the physical and mechanical properties of carbonate rock cores from one of the oil fields in the Republic of Tatarstan. The experimental data obtained, together with the results of geophysical studies of wells and fracture data, were used to calculate the stress-strain state of the rocks ...

Stochastically Generated Digital Twins of 3D Solid‐State Electrolyte Architecture

Advanced Functional Materials, EarlyView.
A stochastic model and validation suite were developed to produce the highest fidelity computer‐generated (Digital Twin) microstructures of random porous tape‐cast solid‐state battery architectures across µm to mm feature sizes from FIB‐SEM to X‐Ray µCT, respectively.

From Measured In Situ Stress to Dynamic Simulation: A Calibrated 3DEC Model of a Rock Quarry

Applied Sciences
Accurately reproducing the mechanical and dynamic behavior of fractured rock masses remains a key challenge in rock engineering, especially in marble quarry environments where discontinuity networks, excavation geometry, and topographic effects induce ...

Ultrawide Bandwidth Optomechanical Magnetometry Using Flux Concentration

Advanced Functional Materials, EarlyView.
High‐permeability flux concentrators enable ultrawide‐bandwidth chip‐scale optomechanical magnetometry by exploiting magnetic nonlinearity to up‐convert low‐frequency fields to the mechanical resonance, where sensitivity is optimal. This enables flat wideband operation over more than four orders of magnitude, from tens of kilohertz to sub‐hertz ...

The “Stress‐and‐Relax” Method for Reconstructing the Coronal Magnetic Field from Vector Magnetograph Data

The Astrophysical Journal, 1996
We describe a promising new technique—the "stress-and-relax" method—for reconstructing the coronal magnetic field from vector magnetograph observations of the underlying photosphere. The computation uses the vector potential representation of the coronal field.

Tuning Redox Dynamics in Cu‐Based Electrocatalysts: Effect of Secondary Metals

Advanced Functional Materials, EarlyView.
Advanced analysis of operando X‐ray absorption spectroscopy data reveals that secondary metals affect the redox processes in Cu‐based catalysts for electrocatalytic CO2 reduction. This influences the amount of oxides formed under pulsed reaction conditions and the distribution of reaction products.

Stress Reconstruction Method for an Ore Carrier Based on Multi-Level Structural Response Fields

e-Journal of Nondestructive Testing
To enhance the real-time response coverage and accuracy of structural health monitoring (SHM) systems for large ore carriers, this study investigates a stress-reconstruction method for a 32.5K DWT ore carrier under limited measurement data. A multi-level reconstruction framework is developed for both global and local responses: at the global scale, a ...
