Bed‐scale quantitative discrimination of hyperpycnites from intrabasinal turbidites—Results from a channelised slope system in the Upper Carboniferous Westward Ho! Formation, United Kingdom

open access: yesSedimentology, EarlyView.
ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...

Analysis of coal drawing law and parameter research in shallow buried double hard and extra-thick coal seam

open access: yes, 2022
The coal resources in Xinjiang are shallowly buried, the coal seam is thick, resulting in poor top coal caving and drawing. And the roof is overhanging in a large area, which makes it impossible to achieve safe and efficient top coal mining.

Top-coal initial caving law of continuous group caving method in extra-thick coal seams

open access: yes矿业科学学报, 2023
In order to clarify the law of top coal caving with continuous group caving method in extra-thick coal seams, this study investigated the influences of the caving openings width on the morphological characteristics of caving body, the evolution law of the boundary of top coal and their spatial relationship based on the discrete element numerical ...

Water‐Stable Paper‐Based Laser‐Induced Graphene With Asymmetric Water Adhesion and Wettability

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 11, 9 June 2026.
Paper‐based electronics are attractive for sustainable and disposable devices, but often fail in wet environments. By introducing Parafilm into cellulose paper combined with laser conversion, two graphene surfaces with different water interactions are created.

Pore Size and Wettability Control Dissolution Trapping Regimes of CO2 in Nano Porous Media

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract We simulate supercritical carbon dioxide (scCO2 ${\text{scCO}}_{2}$) dissolution in water in nano/submicron pore‐throats (14.3–21.5 nm) using a multi‐component, multiphase pseudopotential lattice Boltzmann model closed by a Peng–Robinson equation of state.

Thermo‐Fluorescent Bactericidal Quantum Dots Based Smart Multifunctional Textiles via Molecular Surface Engineering and 3D‐Printed Interlocked Architectures

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 19, 22 May 2026.
A versatile approach is presented for fabricating smart multifunctional textiles by integrating thermo‐fluorescent carbon dot/polymer nanocomposite coatings with 3D‐printed interlocked architectures. The fabrics exhibit temperature‐responsive fluorescence, durable hydrophobicity, strong antibacterial and antioxidant activity, and enhanced UV protection.

Measurement of Coal Body Stress and Research on Reasonable Width of Coal Pillar in Thick Coal Seam with Large Dip Angle

open access: yes, 2020
The mining of thick coal seam is different from the mining of general thick coal seam. The thickness of the first mining is increased, which makes the space of overlying strata rotary movement increase, and it is easy to induce more intense mine pressure.

Machine Learning‐Driven Classification and Production Capacity Prediction of Tight Sandstone Reservoirs: A Case Study of the Taiyuan Formation, Ordos Basin

open access: yesEnergy Science &Engineering, Volume 14, Issue 5, Page 2514-2538, May 2026.
On the basis of core and log data, a Bayesian‐Optimized Random Forest model achieved 92.76% accuracy in classifying tight sandstone reservoirs. A gray relational analysis‐derived evaluation index shows > 80% consistency with actual gas zones. ABSTRACT Tight sandstone gas (TSG), an unconventional oil–gas resource, has heterogeneous reservoirs ...

Comprehensive monitoring and early warning technology for rock burst of tunneling face with thick coal seams

open access: yesYantu gongcheng xuebao, 2019
Through site investigations on thick coal seam rock burst accidents in recent years and studies on their mechanisms, the division method for rock burst of tunneling face is proposed based on the dynamic structure evolution of surrounding rock, that is ...
