Numerical simulation of gas drainage from goaf via high-level borehole in gently inclined seams

open access: yesAIP Advances
Gas disasters pose a significant constraint on the safe development of coal mines. Focusing on the problem of gas over-limits in the upper corner of a hard roof, this study takes the I010206 working face of Kuangou Coal Mine as a case study and proposes ...

Characterization of coal seam permeability stage evolution and gas dynamic transport before and after reaming

open access: yes矿业科学学报
Mechanical reaming technology can significantly improve the permeability of coal seams, thus promoting gas extraction from low-permeability coal seams, and is an effective measure to reduce the risk of gas dynamic disasters. To elucidate the mechanism by

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

open access: yesAdvanced Functional Materials, EarlyView.
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Optimization of an effective extraction procedure for the analysis of microcystins in soils and lake sediments

open access: yes, 2006
Microcystin analysis in sediments and soils is considered very difficult due to low recovery for extraction. This is the primary limiting factor for understanding the fate of toxins in the interface between water and sediment in both the aquatic ...

Gradient‐Conductivity Architecture Enables Synchronous Enhancement of Sensitivity and Detection Range in Multifunctional All‐Paper Sensors

open access: yesAdvanced Functional Materials, EarlyView.
A gradient‐engineered all‐paper sensor is fabricated by integrating MXene and in situ grown AgNPs within hierarchical cellulose networks. The device breaks the sensitivity–detection range trade‐off through cascaded conductive pathways, enabling ultrahigh pressure sensitivity, humidity–pressure decoupled dual‐mode sensing, and outstanding EMI shielding,

Tracking Battery Microstructural Degradation Through Directional Thermal Transport Signatures

open access: yesAdvanced Functional Materials, EarlyView.
In lithium‐ion batteries, heat conduction varies between the through‐plane and in‐plane directions because of the cell's layered structure. Therefore, cell degradation influences thermal conductivity in each direction uniquely due to detailed microstructural and compositional changes.

Kinetics‐Controlled Architecture of Binder‐Free Organic Electrodes for Enhanced Ion Transport

open access: yesAdvanced Functional Materials, EarlyView.
Pulse reverse electrodeposition controls nucleation and growth to create hierarchically porous Py‐derived oligomeric electrodes with enhanced ionic accessibility and reduced transport resistance. The resulting binder‐free architectures translate these transport advantages into practical sodium‐storage functionality.
