Dynamic tensile strength and fracture evolution of characteristic shale with bedding and hole using linear regression theory

Deep Underground Science and Engineering, EarlyView.
The spiral conical perforations generated during methane in situ explosion fracturing operations lead to tensile fracture propagation in shale reservoirs being governed by the combined effects of impact pressure, bedding, and aperture under explosive loading. Using multiple regression analysis and digital image correlation technology, the mechanisms of

EP240801a/XRF 240801B: An X-Ray Flash Detected by the Einstein Probe and the Implications of Its Multiband Afterglow

The Astrophysical Journal Letters
We present multiband observations and analysis of EP240801a, a low-energy, extremely soft gamma-ray burst (GRB) discovered on 2024 August 1 by the Einstein Probe (EP) satellite with a weak contemporaneous signal also detected by the Fermi Gamma-ray Burst

Fitting the Crab Supernova with a Gamma-Ray Burst

Universe
Here, we reconsider the historical data, assuming a gamma-ray burst (GRB) as its source. A Supernova correlated with the GRB explains well the fading time observed by the ancient Chinese astronomers in the daytime and the nighttime, while the GRB power ...

Phosphorus‐Structured Gel Electrolytes Enable Dual Protection for Thermal Runaway‐Resistant Lithium Metal Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The PD‐VI GPE synthesized via in situ γ‐ray polymerization facilitates formation of a dense F/P‐rich SEI layer, enabling stable Li deposition while suppressing interfacial side reactions. The phosphorus‐containing framework enhances separator thermal stability and effectively mitigates O2 release from cathodes, demonstrating improved safety under the ...

The Reduction of Group 6–8 Transition Metal Oxides with Hydrogen—From Ore Smelting to Reaction Pathways#

European Journal of Inorganic Chemistry, EarlyView.
As the reduction of transition metal oxides by coal poses a significant climate risk, the use of alternative reducing agents such as hydrogen is becoming increasingly important. This review summarizes the current knowledge of the reduction pathways of transition metal oxides from groups 6 to 8.

GRB Duration Distribution Considering the Position of the Fermi

Acta Polytechnica, 2012
The Fermi satellite has a particular motion during its flight which enables it to catch the gamma-ray bursts mostly well. The side-effect of this favourable feature is that the lightcurves of the GBM detectors are stressed by rapidly and extremely ...

A Study of the Spectral Properties of Gamma-Ray Bursts with Main and Second Bursts

The Astrophysical Journal
The origins of the main burst and second burst of gamma-ray bursts (GRBs) and the composition of their jets remain uncertain. To explore this complex subject more thoroughly, we conduct a spectral analysis on 18 GRBs with a main and a second burst ...

Effect of Green Hydrogen Enrichment and Carbon Nanotubes Introduced Biodiesel–Diesel Blend on the Behavior of the Diesel Engine Modified to Operate on a Dual‐Fuel Mode

Energy Science &Engineering, EarlyView.
ABSTRACT The influence of n‐heptane mixed with jatropha oil methyl ester (JOME)–diesel with different metal oxide additions, such as aluminum oxide (Al2O3), titanium dioxide (TiO2), and carbon‐based nanoparticles (NPs) including multiwalled carbon nanotubes (MWCNTs) at a quantity of 60 mg/L, and enrichment of hydrogen (H2) at a quantity of 6 lpm are ...
