Charge‐Transfer‐Mediated Boron Magneto‐Ionics: Towards Voltage‐Driven Multi‐Ion Transport

open access: yesAdvanced Science, Volume 13, Issue 55, 5 October 2026.
This study demonstrates voltage‐driven multi‐ion transport in FeBO systems, revealing simultaneous motion of B, Fe, and O ions enabled by charge‐transfer effects. By tuning oxidation states through oxygen incorporation, we achieve a transition from electrostatic‐like to electrochemical magneto‐ionic behavior. The findings establish boron magneto‐ionics,

Glass Properties in the Yttria-Alumina-Silica System

open access: yes, 1987
The glass formation region in the yttria-alumina-silica system was investigated. Properties of glasses containing 25 to 55 wt% yttria were measured and the effect of the composition was determined.

Resolving Redox Anion Exchange and Phase Widths in Yttrium Hydrides by In Situ Neutron Diffraction

open access: yesChemistry–Methods, Volume 6, Issue 10, October 2026.
In situ neutron diffraction reveals that YHO dissolves up to 10 at% O atoms at the H position when heated in air, before transforming to the line phase Y2H0.50O2.75 (or Y2H0.66O2.67 at reduced oxygen availability), and finally to Y2O3; YH3, however, transforms to YH2 and YN when heated in air.

Screening of Ceramic Filler Materials for a Packed‐Bed Thermal Energy Storage System With Lead as Heat Transfer Fluid

open access: yesEnergy Storage, Volume 8, Issue 7, October 2026.
ABSTRACT Liquid lead (Pb) is an attractive heat transfer fluid (HTF) for packed‐bed thermal energy storage (TES) systems aimed for high temperatures. However, liquid Pb is corrosive and its corrosivity increases with rising temperature. Therefore, compatibility tests of possible filler materials with Pb are mandatory.

Improving fatigue resistance of translucent 4Y‐PSZ zirconia through glass gradation

open access: yesEuropean Journal of Oral Sciences, Volume 134, Issue 5, October 2026.
Abstract To evaluate the effect of graded glass infiltration on the fatigue behavior and mechanical reliability of translucent 4Y‐PSZ zirconia before and after hydrothermal aging, disc‐shaped specimens were fabricated by uniaxial pressing and divided into control and glass‐graded groups (n = 36/group).

Synthesis of Dual Phase High Entropy Ultra‐High Temperature Ceramics From Different Carbon Sources

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 5, October 2026.
ABSTRACT Dual phase (Hf,Nb,Ta,Ti,Zr)C‐(Hf,Nb,Ta,Ti,Zr)B2 ceramics were synthesized by boro‐carbothermal reduction of oxides with different carbon black powders. The starting materials reacted differently based on the particle size, surface area, and additives in the carbon powder.
