Does Palsa Thaw in Northern Finland Contribute to Remobilisation of Metals Accumulated in Peat Into Surface Waters?

Land Degradation &Development, EarlyView.
ABSTRACT Permafrost is rapidly degrading in the sporadic zone, including palsa mires in Scandinavia. Peatlands in the area have likely accumulated heavy metals from atmospheric deposition of industrial contaminants in the wider region. As the palsa mire chemical composition is not well known, and in other permafrost regions the permafrost thaw may ...

Structural Analysis and Inhibitor Modeling of Bacterioferritin From Brucella abortus

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Iron homeostasis in various pathogenic bacteria is regulated by bacterioferritins (Bfr) which function to store Fe3+ and release Fe2+ as needed for metabolic processes. The Bfr structure consists of 18 kDa subunits in which dimer pairs bind a heme molecule and are assembled into a highly symmetrical 24‐meric spherical structure with an ...

Surface Sulfate Modification Promoted Excitons Extraction of BiOBr Nanosheets for Efficient 1O2 Photosynthesis and Chlorophenols Dechlorination

Rare Metals, EarlyView.
ABSTRACT Photocatalytic molecular oxygen (O2) activation provides a sustainable approach to produce singlet oxygen (1O2) for organic contaminants detoxification. However, the charge carriers‐involved pathway usually suffers from unsatisfactory 1O2 production efficiency owing to energy loss caused by photogenerated hole‐mediated superoxide species (•O2−

A Comprehensive Review of Adsorbents for Rare Earth Separation: Design, Synthesis, Adsorption Performance, and Mechanisms

Rare Metals, EarlyView.
ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.
