Experimental Investigation of Sensitivity for Coal and Gas Outburst Risk Prediction Indexes in Raw and Tectonic Composite Coal Seams

Energy Science &Engineering, Volume 14, Issue 6, Page 2772-2784, June 2026.
A comparative study was conducted on gas desorption laws of raw and tectonic coals. The sensitivity of regional and local outburst prediction indexes was compared. Gas content is more sensitive than gas pressure for composite coal seams. K1 can more accurately predict the outburst danger than Δ h 2 in composite coal seams.

Alkali Vapor Corrosion of Spinel (MgAl2O4) and Gahnite (ZnAl2O4) Refractories—A Comparative Study

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT Alkali vapor corrosion is critical for refractories used in the kilns and furnaces of diverse high‐temperature processing and manufacturing sectors such as gasifiers, cement production, and glass making. Gahnite (ZnAl2O4) is being investigated as a potential chrome‐free refractory because of its similarity with the structure and properties of ...

Experimental and Theoretical Investigation on the Progressive Breaking Law of Thick and Hard Rock Strata in Deep Mining

Energy Science &Engineering, Volume 14, Issue 4, Page 1881-1902, April 2026.
This work reveals the “C‐Y,” double “Y,” “π,” and “Y” fracture modes of thick, hard strata and their progressive breaking process (O‐F‐R/S mode), providing a theoretical basis for controlling strong ground pressure in deep mining. ABSTRACT In response to the dynamic hazards caused by the fracture of thick‐hard strata in deep mining, this study ...

EDEM-FLUENT coupled simulation of coal-gas outburst two-phase flow

Energy Exploration & Exploitation, 2021
In the process of coal-gas outburst, the gas-solid two-phase flow of pulverized coal and gas will induce large-scale damage to underground mining. In this work, in order to study the dynamic evolution law of gas-solid two-phase flow of coal-gas outburst,

Carbonized Structures With Controlled Pore Direction for Improved CO2 Capturing Using Bio‐Nanofibers

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
This study introduces a method to fabricate hierarchical carbon structures with controlled pore orientation from cellulose, chitin, and chitosan bio‐nanofibers. Using directional freeze‐casting and pyrolysis, centimeter‐scale free‐standing carbons with 100 nm walls were obtained.

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,
