LiCrxFeyMn2−x−y−zTizO4 Spinels as Cathodes for Li‐Ion Batteries: A Multidoping Approach to Suppress Jahn–Teller Distortion

ChemElectroChem, Volume 13, Issue 6, 17 March 2026.
Multidoping of spinel LiMn2O4 with Cr, Fe, and Ti effectively suppresses Jahn–Teller distortion, enhancing structural stability and cycling performance in Li‐ion batteries. Operando X‐ray absorption spectroscopy and ex situ X‐ray diffraction confirm a stable spinel framework and indicate Mn as the only electrochemically active element.

Decoupling Size and Electronic Effects in Doped SrTiO3 Photocatalysts Through Surface Area–Normalized CO2 Hydrogenation Rates

Advanced Functional Materials, Volume 36, Issue 25, 26 March 2026.
Exploring the photocatalytic reverse water–gas shift (RWGS) reaction on doped SrTiO3 nanoparticle films, reveals that normalizing catalytic rates by the catalyst's specific surface area (SSA) disentangled surface area effects from the catalyst's intrinsic material properties.

The characterization of the barium titanate ceramic powders prepared by the Pechini type reaction route and mechanically assisted synthesis

, 2010
BaTiO3 ceramic powders were prepared by a complex method based on the Pechini type reaction route and mechanically assisted synthesis. In both ways BaTiO3 ceramics were sintered after 120 min on 1300 degrees C without pre-calcination steps.

Synthesis of (Bi,Pb)-2223 superconductor powder by pechini method

Revista Brasileira de Física Tecnológica Aplicada, 2018
In this paper, we present a detailed route of synthesis to produce ceramic superconductor Bi1,6Pb0,4Sr2Ca2Cu3Ox (Bi,Pb)-2223 powder by Pechini method. The obtained polymeric precursor solution was produced by using inexpensive chemical reagents, which showed a great stability for three weeks with high concentration of BPSCCO inorganic ions.
