Geological and geotechnical challenges on the Great Dyke of Zimbabwe and their impact on hardrock pillar design

Deep Underground Science and Engineering, EarlyView.
The Great Dyke of Zimbabwe is notable for its rich platinum group metal deposits but poses significant geological and geotechnical challenges due to its complex rock types and structural features. Traditional pillar design methods are insufficient for addressing these complexities; the study suggests incorporating advanced techniques such as machine ...

A review on rockburst prediction and prevention to shape an ontology‐based framework for better decision‐making for underground excavations

Deep Underground Science and Engineering, EarlyView.
A scientometric analysis of 2449 journal articles and a comprehensive review of 336 papers were conducted, discussing and identifying challenges and research gaps in rockburst prediction and prevention and proposing an ontology‐based framework for better decision‐making in underground excavations. Abstract With underground engineering projects becoming

Impacts of large herbivores on mycorrhizal fungal communities across the Arctic

Ecography, EarlyView.
Mycorrhizal fungi play an integral role in nutrient and carbon cycling in soils, which may be especially important in the Arctic, one of the world's most soil carbon‐rich regions. Large mammalian herbivores can influence these fungi through their impacts on vegetation and soil conditions, however the strength and prevalence of these interactions in the

How much species' biodiversity could area targets protect globally?

Ecography, EarlyView.
Protection targets for addressing biodiversity loss include protecting at least 30% of the land and ocean in ecologically representative areas, but do not specify how many or what proportion of species should be protected from extinction. Here, a systematic analysis of 77 880 marine, freshwater and terrestrial species indicates that all species could ...

Temperature variability homogenized thermal responses in an ectotherm community along a European longitudinal gradient

Ecography, EarlyView.
Climate change, through rising temperatures, greater variability, and more frequent extremes, is reshaping insect phenology and thermal niches, with profound effects for pest outbreaks. Predicting these impacts requires a clear understanding of species and communities' responses across geographic gradients.

Ultra‐Fast and Economical Pre‐Breakdown Electrochemical Synthesis of Intrinsically Conductive Polymer Suspension for Production of Safe Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This paper presents a breakthrough pre‐breakdown electrochemical method for synthesizing polyNiMeOSalen suspensions, achieving an 83% yield and nanoscale dispersion ($1500/kg) and environmental impact (1.42 kg CO2eq/kg). We report a novel pre‐breakdown electrochemical synthesis method for producing polyNiMeOSalen suspensions with exceptional ...
