Efficient removal of the recalcitrant metamizole contaminant from drinking water by using a CaLaCoO perovskite supported on recycled polyethylene.

Metamizole (MZ) is a widely used anti-inflammatory drug. Due to its common use, this contaminant is found in sewage and rivers. In order to reduce the contamination produced by the MZ, we fabricated in this work a photocatalytic composite using recycled polyethylene (RPE) and the CaLaCoO (LCCO) perovskite.

Luminescence Properties and Energy Transfer of Eu, Bi Co-Doped LuVO Films Modified with Pluronic F-127 Obtained by Sol-Gel.

Nowadays, orthovanadates are studied because of their unique properties for optoelectronic applications. In this work, the LuVO:Eu, Bi films were prepared by the sol-gel method, using a new simple route, and deposited by the dip-coating technique. The obtained films are transparent, fracture-free, and homogenous.

Structural and Luminescence Properties of Lu₂O₃:Eu F127 Tri-Block Copolymer Modified Thin Films Prepared by Sol-Gel Method.

Lu₂O₃:Eu transparent, high density, and optical quality thin films were prepared using the sol-gel dip-coating technique, starting with lutetium and europium nitrates as precursors and followed by hydrolysis in an ethanol-ethylene glycol solution. Acetic acid and acetylacetonate were incorporated in order to adjust pH and as a sol stabilizer. In order to increment the thickness of the films and orient the structure, F127 Pluronic acid was incorporated during the sol formation.
