Dynamic prediction of coal and gas outburst risk based on quantitative analysis of stress–energy evolution and adaptive correction

Deep Underground Science and Engineering, EarlyView.
This study quantitatively analyzed the spatiotemporal evolution of stress redistribution ahead of the working face by integrating coal seam distribution, tectonic stress anomalies, gas pressure, and mining‐induced disturbances. An R‐value criterion for coal and gas outburst (CGO) risk assessment was established based on energy principles.

3‐Reactor Chemical Looping System for Point Source CO2 Capture and Subsequent Conversion for Liquid Fuel Production

EcoEnergy, EarlyView.
This study presents a novel 3‐reactor chemical looping system for CO2 capture and subsequent utilization with biomass and natural gas for producing liquid fuels. Using Ca2Fe2O5\Fe2O3 oxygen carriers, it achieves 60% CO2 capture efficiency, ∼80% syngas purity, and autothermal operation, offering a scalable, carbon‐negative route to sustainable fuels ...

Hydride Materials for Advanced Electrochemical Energy Storage: Progress and Perspectives

EcoEnergy, EarlyView.
Hydrides are emerging as functional materials for low‐carbon electrochemical energy storage. Complex hydrides provide polyanionic electrolyte frameworks for all‐solid‐state, Li–S, and multivalent batteries; hydride ion conductors enable H− transport for emerging hydride‐based cells; and metal hydrides offer established electrode chemistries for Ni–MH ...

The projected risk of plant invasions on the peri‐Antarctic islands under climate change

Ecography, EarlyView.
The peri‐Antarctic islands have largely been shielded from alien plant species due to low human pressure, limited introduction pathways, and local harsh climates. However, climate change is expected to lower these barriers. We assess the vulnerability of 12 peri‐Antarctic islands to invasion by 2220 plant species invasive in at least one region of the ...

Alternatives to Capitalism in the 21st Century

The COVID-19 pandemic and ensuing global economic recession of unprecedented depth is a 'once in a generation' opportunity to challenge capitalism and transition to a more equitable, democratic, solidaristic and sustainable socio-economic system. Indeed,

Increase in plant productivity in the tundra in Sweden is not related to increasing presence of warm‐adapted vascular plant species

Ecography, EarlyView.
Over the past decades, Arctic and alpine biomes have warmed faster than the global average. Substantial vegetation changes have been reported as a response to this warming, including increased productivity and the spread of warm‐adapted (thermophilic) species that are less resistant to grazing pressure into higher latitudes and altitudes.
