Curcumin-Derived Turn-Off Fluorescent Probe for Copper (II) Ion Detection and Live Cell Imaging Applications.

A curcumin-derived chemosensor 4,4'-((1E,3Z,5Z,6E)-3,5-bis((2hydroxyphenyl)imino) hepta-1,6-diene-1,7-diyl)bis(2-methoxyphenol) (HIBMP) was developed from curcumin and o-aminophenol using Schiff base condensation method. HIBMP selectively recognizes Cu (II) ion (Cu (II)) relative to other tested metal ions. Selective binding of Cu (II) ion turns off the fluorescent property of HIBMP and shows no interference with other metal ions.

Enhanced Adsorption and Photocatalytic Removal of Cationic Dyes in Aqueous Solutions by Ternary Graphene Oxide-TiO₂-SiO₂ Nanocomposites.

In this study, adsorption is an attractive for the removal of industrial dyes from aqueous simulated wastewaters is reported. The ternary graphene oxide-TiO₂-SiO₂ (GTS) nanocomposite was synthesized by sol-gel method. The as-synthesized nanocomposite was characterized by XRD, BET, FT-IR, SEM-EDAX and TEM analysis.
