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.

Electrochemical characterization of YSZ thick films deposited by dip-coating process [PDF]
Yttria stabilized zirconia (YSZ, 8% Y2O3) thick films were coated on dense alumina substrates by a dip-coating process. The suspension was obtained by addition of a polymeric matrix in a stable suspension of commercial YSZ (Tosoh) powders dispersed in an

Environmental-friendly yellow pigment based on Tb and M (M = Ca or Ba) co-doped Y2O3 [PDF]
A yellow inorganic ceramic pigment with general formula Y1.86−xMxTb0.14O3−x/2 (M = Ca and/or Zn) with x = 0.06, 0.32 and 0.64 were synthesized by a modified Pechini method. XRD, SEM and HRTEM/EDX analysis showed the formation of solid solution at 1300 °C

Nano‐ and Micro‐Sized Solid Materials Used as Antiviral Agents
Due to the rise of viral infections in humans and possible viral outbreaks, the use of nano‐ or micro‐sized materials as antiviral agents is rapidly increasing. This review explores their antiviral properties against RNA and DNA viruses, either as a prevention or a treatment tool, by delving into their mechanisms of action and how to properly assess ...

In this research we demonstrated that the energy density of supercapacitors can be enhanced at about 50% by generating extra charge through the use of a photosensitive cell coupled to the supercapacitor estructure. ABSTRACT This research reports a supercapacitor (SC) made with a photosensitive electrode (composed of LaFe0.94V0.01Mn0.05O3 (V‐LFO ...
