Siderophores in environmental research: roles and applications

Introduction. Iron (Fe) is an essential element for the growth of almost all living microorganisms because it acts as a catalyst in enzymatic processes, oxygen metabolism, electron transfer, and DNA and RNA syntheses (Aguado-Santacruz et al., 2012).Fe is also essential for biofilm formation because it regulates surface motility and stabilizes the …

Low-Temperature Fracture of Ultrafine-Grained Iron ...

Metals with a body-centered cubic structure such as iron exhibit a ductile-brittle transition which results in a brittleness below a particular temperature. This temperature depends on many factors such as strain rate, size and geometry of investigated samples or the purity of the material. Another important parameter influencing fracture mechanism is grain size.
