Journal of Raman Spectroscopy, Volume 56, Issue 1, Page 95-112, January 2025.Mn oxides are important geomaterials widely used in various technological applications. In this work, we present our results on the behaviour of the most common Mn oxides having compact and channel structures during laser irradiation. We show that the spinel structure of hausmannite is the final degradation product of all these compounds.

Geobiology, Volume 23, Issue 1, January/February 2025.ABSTRACT The growth and metal enrichment of ferromanganese minerals on the seafloor have intrigued many studies, yet the role of microbes in the process has remained elusive. Here, we assessed the microbial influence on the growth and trace metal accumulation and release of ferromanganese concretions from the Baltic Sea using 12‐week microcosm ...

Lithium Ion Batteries: Characteristics, Recycling and Deep‐Sea Mining
Battery Energy, Volume 3, Issue 6, November 2024.Composite electrodes, as cathode materials, are found to increase electrode stability along with metal carbide‐based anode materials that have shown greater thermal and oxidation resistance. Recycling centres of spent lithium ion batteries are on the rise, with improved techniques such as biometallurgy improving the efficiency of recovering precious ...
