Article Synopsis
- The push for high-strength metals involves reducing grain size, but continuously doing so is tough and can lead to complications like the inverse Hall-Petch effect.
- This study reveals that nanograined metals (NMs) with larger grain sizes (tens of nanometers) can achieve strength levels similar to or exceeding those of much finer NMs (around 5 nm) through a process called dislocation exhaustion.
- The research focuses on Fe-Ni NMs with enriched nickel at grain boundaries, showing that low-temperature structural transformations at these boundaries help reduce dislocations and enhance plasticity, paving the way for ultra-hardening effects and new strategies in material design.
A survey of microbial contamination in aviation fuel from aircraft fuel tanks.
Folia Microbiol (Praha)
April 2020
Microbial contamination poses a great threat to aviation system security through mechanisms such as microbiologically influenced corrosion (MIC), fuel filter clogging, and fuel deterioration. In this study, a survey of microbial contamination in aviation fuel obtained from aircraft fuel tanks was performed to test the relationship between microbial contamination and aircraft service life. The contaminating microorganisms were counted, isolated, identified, and subjected to preliminary characterization.
