Temperature-Controlled Synthesis of High-Voltage Spinel LiNi0.5Mn1.5O4 Films via Metal–Organic Decomposition: Structure and Electrochemical Study for Application in Lithium-Ion Batteries

Francisca Luco, Benjamín Silva, Andrés Ibáñez, Arianne Maine et autres

The high-voltage spinel LiNi0.5Mn1.5O4 (LNMO) is a promising cobalt-free cathode material for lithium-ion batteries, yet its integration as a binder-free thin film on metallic current collectors via simple solution routes remains underexplored. Here, LNMO films were synthesized on 304 stainless steel (SS304) …

Solvent-Free Mechanochemical Synthesis of Cyclodextrin Nanosponges via Mechanical Milling for Removal of Dinotefuran from Water

Sebastián Salazar Sandoval, Arianne Maine, Freddy Célis, Diego Cortés‐Arriagada et autres

Cyclodextrin-based nanosponges (NSs) have gained attention as sustainable adsorbents for emerging pollutants. However, conventional cyclodextrin cross-linking typically involves toxic solvents and prolonged reaction times, which complicate synthesis and purification. In this work, NSs were synthesized using a solvent-free mechanochemical process via mechanical …

Photoluminescence modification of europium( iii )-doped MAl 2 O 4 (M = Zn, Mg) spinels induced by Ag@SiO 2 core–shell nanoparticles

Rodrigo A. Valenzuela-Fernández, Arianne Maine, Julien Cardin, Xavier Portier et autres

modified-surface led to a significant increase in photoluminescence. The study also analyzed the photoluminescence excitation and lifetimes of the oxides, leading to a 7.3-fold increase in photoluminescence. The improvements observed in the luminescence of these tailor-made materials show their potential interest in …
