TL;DR: A review of the research on green synthesis of silver metal nanoparticles and the influence of the method on their size and morphology can be found in this paper, where the authors describe a brief overview of their work.

TL;DR: In this paper, the authors thank CAPES from Brazil for the financial support of this work, which is also a result of project "AIProcMat@N2020 − Advanced Industrial Processes and Materials for a Sustainable Northern Region of Portugal 2020" with the reference NORTE-01-0145-FEDER-000006 and the project BioTecNorte (operation NORTE -01-145-FCF-000004), supported by Norte Portugal Regional Operational Programme (NORTE 2020), under the Portugal 2020 Partnership Agreement, through the

TL;DR: In this article, different rare earth element (Dy, Gd, Tb and Yb) doped LiMn2O4 spinel active materials were prepared by a sol-gel method and two pairs of separated redox peaks were observed, regardless of the dopant.

TL;DR: In this article, a preferential substitution of Ln3+ by Na+ ions in 4f position for both materials was suggested, which impacts their local symmetry, optical properties, and quantum efficiency, and evidence of concentration quenching effects was discussed based on the 5D0 lifetime and the emission quantum yield dependence on the Eu3+ concentration.
