Mining of deep-seabed nodules using a Coandă-effect-based collector

Results in Engineering, 2023
We present an effective design of a hydraulic, polymetallic nodule collector, which fundamentally depends on the Coandă effect in harvesting nodules. The design was first developed based on 2D numerical simulations conducted using a computational fluid ...

From Quarries to Urban Construction Sites: Middle‐Late Mesozoic Limestones in the Public Architecture of Roman Verona, Italy

Geoarchaeology, Volume 41, Issue 1, January/February 2026.
ABSTRACT Numerous buildings, monuments, and infrastructural works in Verona were constructed during the Roman period using stone, a material abundantly available from quarrying areas located relatively close to the city. Petrographic investigations conducted by Transmitted Polarized Light Optical Microscopy (TPL‐OM) and complemented by colorimetric ...

A review of megafauna diversity and abundance in an exploration area for polymetallic nodules in the eastern part of the Clarion Clipperton Fracture Zone (North East Pacific), and implications for potential future deep-sea mining in this area

Marine Biodiversity, 2023
The Clarion Clipperton Fracture Zone (CCZ) is an abyssal region in the north-east Pacific that is currently being explored for metal-rich polymetallic nodules, but also harbors a highly diverse megabenthic community.

Characterization and Reuse of Lithium‐ion Battery Cathode Material Recovered Through a Bacterial Process

Advanced Energy Materials, Volume 15, Issue 46, December 9, 2025.
A sustainable bacteria‐based lithium‐ion battery cathode recycling method is optimized using engineering biology. The resulting biomineralized manganese carbonate species is found to be easily converted into an electrode material, via simple calcination.

Giant, highly diverse protists in the abyssal Pacific: vulnerability to impacts from seabed mining and potential for recovery

Communicative & Integrative Biology, 2020
Xenophyophores, giant deep-sea agglutinated foraminifera, dominate the benthic megafauna in the eastern equatorial Pacific Clarion-Clipperton Zone. This abyssal (>4000 m depth) region hosts major deposits of polymetallic nodules targeted for future ...

Rethinking Sustainable Batteries

Advanced Energy Materials, Volume 15, Issue 47, December 16, 2025.
This perspective examines sustainability across the entire battery lifecycle, from mining and manufacturing to use and end of life. Twelve principles for ‘green’ batteries are outlined, and it is argued that joint industrial, academic, and policy efforts are essential to building a truly sustainable energy future. Abstract Batteries will play a pivotal

Heterogeneous marine environments diversify microbial-driven polymetallic nodule formation in the South China Sea

Frontiers in Marine Science
Most studies on the genesis of polymetallic nodules suggested that nodules in the South China Sea (SCS) are hydrogenetic; however, the complexity and the heterogeneity in hydrology and geochemistry of the SCS might cause different processes of nodule ...
