Use of closured open pit and underground coal mines for energy generation: Application to the Asturias Central Coal Basin (Spain)

open access: yesE3S Web of Conferences, 2019
The idea to reducing the dependency of nuclear and fossil energy sources has risen in Spain, then, the use of closured coal mines for energy generation is thus in the political interest, and by 2020 it is intended that the country produces 20% of its ...

Agrarian counterpoint

open access: yesAmerican Ethnologist, Volume 53, Issue 2, Page 171-182, May 2026.
Abstract In Colombia's northeastern borderlands, agrarian economies shape how disease risk and stigma are understood and managed. As shown in ethnographic fieldwork in and around the Catatumbo region, cutaneous leishmaniasis—a sandfly‐transmitted disease that produces chronic skin lesions—appears in two radically different guises across adjacent ...

Stage-Wise Simulation for Operational Stability Evaluation of Seasonal Heat Storage in Abandoned Coal Mines

open access: yesEnergies
The development of coal resources has created a large number of underground mined-out spaces, which can be utilized for cross-seasonal thermal storage through underground reservoirs to achieve seasonal heat storage.

Effects of warming on plant uptake of post‐fire nitrogen in an arctic heath tundra

open access: yesNew Phytologist, Volume 250, Issue 3, Page 1510-1521, May 2026.
Summary Postfire nitrogen (N) becomes increasingly important with the rising frequency of fires in arctic tundra, and climate warming is expected to accelerate plant recovery following fire. However, how plants differ in utilizing this postfire N and how their postfire N uptake responds to warming remains unknown.

Adsorption Preceding Wetting Front Controls Seismic Velocity

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Rock elasticity varies with both humidity and water saturation, yet their combined effects remain poorly understood, although in nature vapor adsorption and liquid infiltration occur simultaneously. Here, we present experimental data of P‐wave velocity and volume expansion in a free‐standing sandstone subject to progressive wetting.

Elaboration and application of the nested multi-coupling model test system for an artificial dam seepage simulation under combined action of dynamic and static loads

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources
Outdated coal mining technologies involve considerable mine water resource waste. For coal mines located in water-starved western regions of China, this jeopardizes the sustainable coal mining development, local eco-environment, and agricultural ...

The Hematite Question: Hydrogen‐Driven Magnetization of Hematite‐Bearing Sandstones and Insights for Natural Hydrogen Exploration

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Natural hydrogen is a promising clean energy resource, but locating subsurface accumulations remains challenging. Aeromagnetic anomalies are increasingly utilized as a rapid and cost‐effective tool for geological hydrogen prospection, particularly associated with magnetite formation during abiotic geochemical hydrogen generation through ...
