Microstructural Engineering of Sodium Potassium Niobate for Enhanced and Temperature‐Stable Electromechanical Response

International Journal of Applied Ceramic Technology, Volume 23, Issue 3, June 2026.
This study investigates the synergistic effects of Ti‐doping and K5.4Cu1.3Ta10O29 (KCT) co‐modification on KNN ceramics to develop sustainable, lead‐free piezoelectrics. Co‐modification significantly enhances electromechanical coupling and the mechanical quality factor. The optimized KNN‐Ti‐KCT system achieves thermal stability comparable to commercial

Spin Transition of Fe3+ in δ‐(Al,Fe)OOH and Implication for Mid‐Lower Mantle Seismic Heterogeneities

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract δ‐(Al,Fe)OOH is an important water carrier and plays a critical role on Earth's deep water cycle. Lattice parameters of δ‐(Al0.89Fe0.11)OOH were measured by synchrotron single‐crystal X‐ray diffraction at simultaneously high temperature and pressure up to 65 GPa and 800 K in diamond anvil cells.

Raman Spectroscopic Identification of Oxide Phases in a Corroded MgO–Steel Composite Anode Used in Aluminum Molten Salt Electrolysis

Advanced Engineering Materials, Volume 28, Issue 10, 20 May 2026.
Micro‐Raman spectroscopy is applied to characterize corrosion products in a recycled‐based MgO–316L steel composite anode after molten salt electrolysis. A depth‐dependent Fe–O/Fe–Al–O layer sequence of magnetite, hercynite, and an Al‐doped magnetite transition zone is identified.

Impact of Pre‐Oxidation Treatments on a Recycled MgO/Steel‐Composite as Carbon Free Anode in Aluminum‐Electrolysis Environments

Advanced Engineering Materials, Volume 28, Issue 10, 20 May 2026.
Cermets (60 vol.% AISI 316L stainless steel, 40 vol.% recycled MgO), intended for use in aluminum electrolysis, were pre‐oxidized in three furnaces with different heating technologies and subjected to a cryolite corrosion test. The different atmospheres influenced the formation of oxide layers, which in turn affected corrosion resistance and ...

Microwave Synthesis of CuNi/TiO2 Nanotubes for Enhanced Photocatalytic H2 Generation

ChemPhysChem, Volume 27, Issue 9, 14 May 2026.
A simple microwave synthesis technique to decorate spaced TiO2 nanotubes (NTs) with CuNi species that show significantly enhanced photocatalytic hydrogen generation. Microwave‐assisted synthesis offers several advantages over conventional methods, including shorter reaction times and more efficient heating in systems containing polar solvents such as ...
