Lanmodulin‐Decorated Microbes for Efficient Lanthanide Recovery

Advanced Materials, Volume 37, Issue 10, March 12, 2025.
Bio‐scaffolded lanmodulin (LanM) on E. coli is developed as a simple, effective material for repeated capture and release of rare earth elements (REEs). Over 80% of four REE cations are captured, even in the presence of excess competitive ions. The material can be employed in a filtration flow‐through system with a capture capacity of 11.8 ± 0.9 mg g−1

Effect of heat treatment on bio-corrosion rate of steel structure (API 5L) in marine evironment

MATEC Web of Conferences, 2018
One of the cause of corrosion is the attachment of bacteria or commonly called as bio-corrosion or Microbial Influenced Corrosion (MIC). This aim of the research was to determine effect of heat treatment process on the bio-corrosion rate of API 5L steel.

Characterize the Growth and Metabolism of Acidithiobacillus ferrooxidans under Electroautotrophic and Chemoautotrophic Conditions

Microorganisms
Acidophiles are capable of surviving in extreme environments with low pH. Acidithiobacillus ferrooxidans is a typical acidophilic bacterium that has been extensively studied when grown chemoautotrophically, i.e., when it derives energy from oxidation of ...

Recycling of Critical Metals from Light‐Emitting Diodes

Chemie Ingenieur Technik, Volume 97, Issue 1-2, Page 110-115, February 2025.
The new process for recovering the critical metals indium and lutetium from light‐emitting diodes uses polyvinyl chloride (PVC) or PVC waste as a cheap chlorine source for the chlorination of indium for evaporation. The residue was leached out and the filtrate was used for liquid‐liquid extraction to recover lutetium, as a test‐of‐concept study ...
