Diminished Chandler Wobble After 2015: Link to Mass Anomalies in 2011

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract Observed polar motion after 2015 is dominated by the annual wobble, due to unprecedented amplitude reduction of the Chandler Wobble component. This change is likely due to suppression of the 433‐day‐period free wobble by geophysical excitation sources.

GRACE Detection of Transient Mass Redistributions During a Mineral Phase Transition in the Deep Mantle

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract The temporal evolution of the core‐mantle boundary (CMB) is of critical importance in elucidating the dynamic interactions between the fluid core and the solid mantle, but remains largely unknown. To investigate corresponding mass redistributions, we analyze GRACE satellite and Satellite Laser Ranging (SLR) measurements of the 2003–2015 space ...

Tailoring an Fe–Ov–Ce–Triggered Phase‐Reversible Oxygen Carrier for Intensified Chemical Looping CO2 Splitting

Carbon Energy, Volume 7, Issue 9, September 2025.
A phase‐reversible CeO2‐x·Fe·CaO↔CeO2·Ca2Fe2O5 oxygen carrier is designed and synthesized with enhanced CO2‐splitting capability and robust redox durability. The engineered Fe–Ov–Ce structure acts as an initiator to induce CO₂ activation and dissociation, Fe acts as an active phase to accommodate oxygen ions from CO₂ dissociation, and CaO functions as ...

Estimation and Attribution of Horizontal Land Motion Measured by the Greenland GNSS Network

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract Horizontal land motion, as observed by geodetic techniques such as Global Navigation Satellite Systems (GNSS), is generally dominated by tectonic plate movement. However, in regions that are currently or formerly glaciated, such as Greenland, the deformation of the solid Earth due to surface loading complicates the separation of tectonic and ...

Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.

Advanced Photonics Research, Volume 6, Issue 8, August 2025.
Photophysical properties of TADF molecules are determined by characteristic parameters that are discussed in detail(. Moreover, using femtosecond time‐resolved spectroscopy, quantum mechanical considerations, and state‐of‐art calculations, deeper understanding allows us to design breakthrough Cu(I) and organic TADF‐ OLED materials. For the latter ones,
