Quantification of rheological parameters in deep‐sea mining plumes

Deep Underground Science and Engineering, Volume 5, Issue 1, Page 250-265, March 2026.
This study explores the variations in rheological properties observed during the propagation of deep‐sea mining plumes, utilizing rheological test data obtained from kaolin clay plumes. Subsequently, taking into account the differences in sediment properties, the effects of clay content and clay mineral composition on the rheological parameters of ...

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 ...

Benthic and Demersal Scavenger Biodiversity in the Eastern End of the Clarion-Clipperton Zone – An Area Marked for Polymetallic Nodule Mining

Frontiers in Marine Science, 2020
In the Clarion-Clipperton Zone (CCZ) in the north-eastern Pacific Ocean ca. 30 billion tonnes of polymetallic nodules, rich in metals critical for frontier technologies, lay on the sediment surface over an area of 4–5 million square kilometres.

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.

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

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 ...

Experimental seabed disturbance effects on Chatham Rise deep‐sea meiofaunal communities, Southwest Pacific

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1388-1421, December 2025.
ABSTRACT Growing global demand for deep‐sea resources may lead to increased pressure on benthic ecosystems. Here we examined changes in meiofaunal communities following an in situ physical disturbance experiment. A significant change in meiofaunal community structure in surface (0‐1 cm) and subsurface (1‐5 cm) sediments was observed immediately ...
