Fast Removal of Methylene Blue via Adsorption-Photodegradation on TiO/SBA-15 Synthesized by Slow Calcination.

TiO/SBA-15 photocatalysts were successfully prepared by impregnating low loading titania to SBA-15 via slow calcination. The photocatalyst is efficient for fast methylene blue removal via adsorption and photodegradation methods. The impregnation of low TiO loading via slow calcination enhanced TiO dispersion that preserved the SBA-15 porosity and uniform morphology.

Synthesis of urea-modified magnetic nanocomposites iron oxide/carbon as a potential biomaterial produced by arc discharge in liquid medium and its in-vivo toxicity assessment.

Carbon-encapsulated magnetic nanoparticles are promising candidate materials for drug-delivery applications. However, due to their hydrophobic and aggregation properties, which indicate lower biocompatibility, proper surface modification of the carbon-based material is required. In the present study, we present the facile route to producing biocompatible magnetic nanocomposite iron oxide/carbon using the liquid medium arc-discharge method.
