Failure Mechanism and Control Technology of Thick and Soft Coal Fully Mechanized Caving Roadway under Double Gobs in Close Coal Seams

open access: yes, 2020
The surrounding rock of the roadway under double gobs in the lower coal seams is partially damaged by the mining of the upper coal seam and the stress superimposition of the stepped coal pillars.

Metal‐Free Submicron‐Hollow‐Fiber Conjugated Polymer Sponges for Efficient Pollutant Removal and Thermal Insulation

open access: yesSmall, Volume 22, Issue 24, 27 April 2026.
Mimicking natural tubular structures, metal‐free conjugated hollow fibers are synthesized via one‐pot Chichibabin condensation. Pyridinic networks spontaneously self‐assemble into submicron hollow fibers and entangle into spongy monoliths—without templates, metals, or post‐processing.

Racialized Labour in the Colonial Food Regime: The Whitening of England's Farmworkers

open access: yesJournal of Agrarian Change, Volume 26, Issue 2, April 2026.
ABSTRACT The crystallization of a colonial food regime in the 1870s centred around Britain is key to historical accounts of agrarian political economy. Yet such accounts have neglected the role of the agrarian proletariat in shaping this regime from below and its basis in racialized hierarchy.

Failure mechanism of the coal wall at the working face based on an eccentric compression mechanical model

open access: yesDeep Underground Science and Engineering, Volume 5, Issue 1, Page 127-143, March 2026.
In this study, the nonuniform distribution of the bearing pressure in front of the coal wall has been revealed based on in situ monitoring data and numerical simulation results. Therefore, an eccentric compression mechanical model of the coal wall was established to study the deformation and failure characteristics of a coal wall. The slenderness ratio
