Oxygen Evolution Reaction Catalysts for Acidic‐Media CO2 Electrolyzers

Advanced Materials, Volume 38, Issue 19, 1 April 2026.
Acidic‐media CO2 electroreduction (CO2R) could decarbonize chemical production, despite relying on rare‐earth elements for anodic oxygen evolution reaction (OER). Transferring the learnings from mature sister technologies (water electrolysis) could accelerate technological development.

Synthesis of superconducting pyrochlore RbOs2O6

, 2004
RbOs2O6, the third superconducting pyrochlore oxide (known so far), has been synthesized by encapsulation and by high pressure techniques. Suitable post chemical treatment of the as-prepared sample allowed us to eliminate the impurity phases.

Vacancy‐Suppressed Garnet Electrolytes for Durable Solid‐State Batteries

Advanced Science, Volume 13, Issue 21, 13 April 2026.
A Li/O‐rich sintering strategy effectively suppresses intrinsic lithium and oxygen vacancies in cubic garnet electrolytes, yielding a dense and stable microstructure. The vacancy‐controlled electrolyte exhibits enhanced interfacial and air stability, enabling long‐term solid‐state battery cycling and providing a general design principle for defect ...

Quantum generalized constant coupling model for geometrically frustrated antiferromagnets

, 2000
A generalized constant coupling approximation for quantum geometrically frustrated antiferromagnets is presented. Starting from a frustrated unit, we introduce the interactions with the surrounding units in terms of an internal effective field which is ...

Electronic and Structural Determinants of Activity and Stability in Noble Metal OER Catalysis

ChemCatChem, Volume 18, Issue 7, 14 April 2026.
Activity and stability in noble metal oxygen evolution reaction (OER) catalysts arise from coupled electronic and structural effects at the catalyst surface. Electronic engineering, crystallographic control, lattice modulation, and surface engineering tune the d‐band structure, oxidation state, strain, and coordination environment of noble metal based ...

Fractionalized charge excitations in a spin liquid on partially-filled pyrochlore lattice

, 2014
We study the Mott transition from a metal to cluster Mott insulators in the 1/4- and 1/8-filled pyrochlore lattice systems. It is shown that such Mott transitions can arise due to charge localization in clusters or in tetrahedron units, driven by the ...

High Efficiencies in Gd2Ru2O7 Pyrochlore Oxide Photoanode‐Based Dye‐Sensitized Solar Cells Using Natural Dyes From Anacardium, Baphia nitida, and Lannea kerstingii Barks

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 4, Page 453-464, April 2026.
High performance of Gd2Ru2O7‐based natural dye‐sensitized solar cell using three different dyes (Anacardium, B. nitida, and Lannea kerstingii barks) has been developed. Enhanced energy conversion efficiency values were obtained compared to classical TiO2 P25‐based DSSC. ABSTRACT Natural dye‐sensitized solar cells (DSSC‐N), inspired by the principles of
