Mineral replacement reactions are one of the most important phenomena controlling the geochemical cycle of elements on Earth. In the early years, solid-state diffusion was proposed as the main mechanism for mineral replacement reactions, but over the

Photocatalysts for harvesting solar energy to either electricity or chemical fuels have attracted much attention recently, but they have big obstacles such as wide bandgaps and rapid charge recombinations to overcome for final applications. In this s

Copper azide with high density was successfully synthesized by in-situ reaction of nanoporous copper (NPC) precursor with HN3 gaseous. NPC with pore size of about 529 nm has been prepared by electroless plating using polystyrene (PS) as templates. Th

This study sought to clarify whether suspended particles containing high Cu concentrations are present in the sea-surface microlayer (S-SML). For this reason, suspended particles (10–2000 μm) in the S-SML were collected periodically from a ship mo

Heavy metal resistance (Cu, Zn, Fe, Cr, Pb, Cd) and removal capacities of 19 selected actinobacteria strains were performed in order to investigate their applicability as bioremediators for polluted areas. Streptomyces sp. WR1L1S8 was used in the pre

In order to find a cost-effective remediation to treat lead (Pb)- and copper (Cu)-contaminated agricultural soil, the particle-size sieving technique (PST) combined with the replacement of clean sands was employed in this study. The speciation and re
