Bimetallic Synergy in Cocatalyst Alloy Nanoparticles for Efficient Photocatalytic Hydrogen Production

EcoEnergy, EarlyView.
A bimetallic NiAg alloy is assembled on the surface of Zn3In2S6 to construct a NiAg‐Zn3In2S6 composite using a chemical reduction method. By adjusting the different alloy ratios, the hydrogen evolution activity of the optimum Ni0.25Ag0.75‐Zn3In2S6 photocatalyst achieves 21.32 mmol·g−1·h−1. ABSTRACT A bimetallic NiAg alloy is assembled on the surface of

Revealing Long-Term Displacement and Evolution of Open-Pit Coal Mines Using SBAS-InSAR and DS-InSAR

Remote Sensing
Coal mines play an important role in the global energy supply. Monitoring the displacement of open-pit mines is crucial to preventing geological disasters, such as landslides and surface displacement, caused by high-intensity mining activities. In recent

Aquatic and Littoral Successions in Various Post‐Mining Sites—Patterns and Possible Use in Ecological Restoration

Land Degradation &Development, EarlyView.
ABSTRACT Vegetation succession in aquatic and littoral habitats has received much less attention than terrestrial habitats have. We sampled differently aged successional stages at five different types of post‐mining sites, that is, sandpits, stone quarries, clay quarries, brown coal spoil heaps and black coal subsidences, across the Czech Republic ...

Coal and Open-pit surface mining impacts on American Lands (COAL)

, 2018
COAL is a Python library for processing hyperspectral imagery from remote sensing devices such as the Airborne Visible/InfraRed Imaging Spectrometer (AVIRIS). COAL was originally developed as a 2016 – 2017 senior capstone collaboration between scientists at the Jet Propulsion Laboratory (JPL) and computer science students at Oregon State ...

Coal Mining as a Driver of Land Use and Land Cover Change and Degradation: A Case in Moatize City, Mozambique

Land Degradation &Development, EarlyView.
ABSTRACT Coal remains a major global energy source despite ongoing environmental controversies, particularly, regarding climate change and landscape transformation. This study investigates the spatiotemporal dynamics of land use and land cover (LULC) in the Moatize Coal Basin (MCB), Mozambique, between 1990 and 2024, with a specific focus on land ...

Vegetation dynamics and dominant driving factors in a semi-arid coal mining area under a disturbance–restoration zoning framework

Geocarto International
Understanding vegetation dynamics in arid mining ecosystems remains limited, despite the extensive disturbances imposed by mining activities. Integrating remote sensing and field observations, we applied the Mann–Kendall test, Theil–Sen slope, the ...

Steep seam coal mining in Western Canada by open pit mining

, 1984
Canada produces close to 42 million tonnes of coal per annum of which soma 38 million tonnes is produced by surface mining methods. The two Western Canadian provinces, Alberta and British Columbia, produce 31 million tonnes of coal by surface mining. These two provinces provide the bulk of the metallurgical coal for export. The geological conditions in

Trade Unions and Sustainability: An Integrative Review

Sustainable Development, EarlyView.
ABSTRACT Despite the growing presence of trade unions (TUs) in sustainability discussions, academic research on their role is still scattered. This article presents an integrative review of 110 peer‐reviewed English‐language academic articles on this topic, indexed in Scopus and Web of Science and published between 1997 and early 2025.
