Study on Corrosion and Thermal Alteration of Low‐Cost Storage Materials for Use in High‐Temperature Thermal Energy Storage Systems With Lead as the Heat Transfer Fluid

Energy Storage, Volume 7, Issue 8, December 2025.
ABSTRACT Liquid metal packed‐bed thermal energy storage (TES) can improve industrial waste heat recovery due to its wide operating temperature range and high thermal conductivity. However, reducing costs, especially for storage media, is essential for broader adoption.

Order, Disorder, and Dynamics in Brownmillerite Sr₂Fe₂O₅ [PDF]

Inorganic Chemistry, 2019
The room-temperature structure of brownmillerite-type Sr2Fe2O5 remains controversial, despite numerous published crystallographic studies utilizing X-ray, neutron, and electron diffraction data collected on single-crystalline and powder samples. The main disagreements concern the ordering of twisted FeO4 tetrahedral chains within and between the layers

Local p‐ and n‐Type Doping of an Oxide Semiconductor via Electric‐Field‐Driven Defect Migration

Advanced Science, Volume 12, Issue 43, November 20, 2025.
Local acceptor and donor doping is achieved in a semiconducting oxide by controlled splitting of oxygen interstitial‐vacancy pairs under applied d.c. voltage. The separated oxygen defects are demonstrated to form interstitial‐rich (p‐type) and vacancy‐rich (n‐type) regions, comparable to dipolar npn‐junctions, enabling transient functionalization ...

Reversible Phase Transitions Enable Cyclic Isothermal CO2 Capture in Redox‐Activated Perovskite‐Structured Sorbents

Advanced Functional Materials, Volume 35, Issue 40, October 1, 2025.
Perovskite‐structured SrMnO3 can cyclically and reversibly capture and release CO2 via redox‐enabled phase transitions at constant temperature. The efficacy of this novel redox‐activated CO2 sorbent is demonstrated via sorption‐enhanced steam methane reforming.

Modulating Oxide‐Based Quantum Materials by Ion Implantation

Advanced Functional Materials, Volume 35, Issue 43, October 22, 2025.
This review highlights how ion implantation, a well developed chip‐technology, enables targeted modulation of oxide‐based quantum materials. This includes tuning of metal‐insulator transitions, magnetism, and superconductivity through selective doping, defect creation, and induced lattice strain. Abstract Ion implantation has emerged as a powerful tool

Topotactic synthesis of strontium cobalt oxyhydride thin film with perovskite structure

AIP Advances, 2015
The substitution of hydride anions (H−) into transition metal oxides has recently become possible through topotactic reactions or high-pressure synthesis methods. However, the fabrication of oxyhydrides is still difficult because of their inherently less-
