The seabed - an important mineral resource of Slovakia in the future [PDF]

Acta Montanistica Slovaca, 2015
In 1987, Slovakia bought part of the ocean bottom with the occurrence of mineral resources future - polymetallic nodules. The polymetallic nodule is a geological term for naming natural features consisting of more than 40 metals and other chemical ...

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

Seafloor surficial sediment variability across the abyssal plains of the central and eastern pacific ocean

Frontiers in Earth Science
Abyssal plains lie at water depths of 3,000–6,000 m and account for 84.7% of the global ocean seafloor. This vast landsystem is believed to be one of the major reservoirs of biodiversity within the deep-sea.

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 ...

Effects of experimental in situ seabed disturbance on deep‐sea macrofaunal communities of Chatham Rise, Southwest Pacific

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1422-1459, December 2025.
ABSTRACT With the possibility of deep‐sea mining of mineral resources occurring, it is necessary to understand potential impacts on benthic communities. Previous simulated mining experiments revealed direct benthic impacts; however, indirect impacts of sedimentation are not well understood.

Almost billfish: convergent longirostry, micro‐dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy

Journal of Anatomy, Volume 247, Issue 6, Page 1109-1130, December 2025.
A fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.

Micro-Tomographic Investigation of a North-Western Pacific Polymetallic Nodule

Quaternary
Micro-computed tomography (μCT) and X-ray Fluorescence (XRF) were used to investigate a Polymetallic Nodule (PN) from the North-Western Pacific abyssal plain to gather more information concerning the environmental changes that could be reflected by the ...

Millennial‐Scale Hydrothermal Variability at the Carlsberg Ridge Driven by Sea‐Level Change and Transient Magmatism

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract Hydrothermal systems at mid‐ocean ridges (MORs) mediate the transfer of heat and geochemical fluxes from the mantle to the hydrosphere, facilitating fluid‐rock interaction and metal cycling. While short‐term hydrothermal dynamics are well studied, the long‐term response of these systems at slow‐spreading ridges to glacial‐interglacial sea ...

The Stability of Manganese Oxides Under Laser Irradiation During Raman Analyses: II. Layer Structures

Journal of Raman Spectroscopy, Volume 56, Issue 10, Page 1072-1088, October 2025.
Manganese oxides are important geomaterials with diverse technological applications. Here, we investigate the behaviour of the most common Mn oxides with layer structures under irradiation by a 532‐nm laser, with intensity ranging from 23 µW/µm2 to 36.8 mW/µm2.

Advancing Nitrate‐to‐Ammonia Electrocatalysis: Strategies in Catalyst Design, Electrolyte Engineering, and Performance Evaluation

Advanced Science, Volume 12, Issue 34, September 11, 2025.
This review highlights the latest advances in electrocatalytic nitrate reduction to ammonia, with a focus on catalyst design strategies, electrolyte engineering, and performance evaluation. Abstract The electrochemical reduction of nitrate for ammonia production not only offers a promising alternative to the traditional Haber–Bosch process, which ...
