Carbon-Nanotube-Based Superhydrophobic Magnetic Nanomaterial as Absorbent for Rapid and Efficient Oil/Water Separation.

In this work, the simple fabrication of a new superhydrophobic magnetic sponge based on CNTs, NiFeO nanoparticles, and PDMS was investigated. CNTs were synthesized by chemical vapor deposition (CVD) on a nickel ferrite catalyst supported on aluminum oxide (NiFeO/AlO). The synthesis of nickel ferrite (NiFe) was accomplished using the sol-gel method, yielding magnetic nanoparticles (43 Amkg, coercivity of 93 Oe, 21-29 nm).

Accelerated solvent extraction of carotenoids from: Tunisian Kaki (Diospyros kaki L.), peach (Prunus persica L.) and apricot (Prunus armeniaca L.).

Extraction of carotenoids from biological matrices and quantifications remains a difficult task. Accelerated solvent extraction was used as an efficient extraction process for carotenoids extraction from three fruits cultivated in Tunisia: kaki (Diospyros kaki L.), peach (Prunus persica L.
