Fluorescing Layered Double Hydroxides as Tracer Materials for Particle Injection during Subsurface Water Remediation

Mine water tracer tests as a basis for remediation strategies

Mining usually causes severe anthropogenic changes by which the groundor surface water might be significantly polluted. One of the main problems in the mining industry are acid mine drainage, the drainage of heavy metals, and the prediction of mine water rebound after mine closure. Therefore, the knowledge about the hydraulic behaviour of the mine water within the flooded mine might significant...

Biological Application of Layered Double Hydroxides in Drug Delivery Systems

This review focuses on the extensive study of different layered double hydroxides (LDHs)nanostructures and also their biological and physicochemical (in vitro) properties to encapsulateand deliver drugs with a recognized pharmacokinetic profile in a sustained/modified manner forbetter remedial efficacy contrasted to the corresponding conventional treatments using different<br ...

Layered double hydroxides: noble materials for the development of multi-functional nano- hybrids

Layered double hydroxides (LDH), auch als anionische Tonmineralien bekannt, werden seit längerem in der Katalysetechnik und in verschiedenen biologischen und medizinischen Anwendungen eingesetzt. Die Nutzung von LDH als multifunktionelle Nanofüllstoffe ist in den letzten Jahren in der Polymerforschung forciert worden. Dazu trugen die positive Ladung der Hydroxidschichten, die im Gegensatz zu de...

The ability of layered double hydroxides for nitrate absorption and desorption in crop and fallow rotation

BACKGROUND AND OBJECTIVES: This study aims down to evaluate the ability of chloride magnesium- aluminium- layered double hydroxides (4:1) for nitrate adsorption from the soil solution in successive cropping periods. METHODS: The study was conductedunder long-term cropping periods, including first crop): bell pepper; second crop: mentheae; third crop: cher...
