Cross‐Correlation Between Crystallinity and Optoelectronic Properties of Mixed‐Perovskite Thin Films Through Multiple Time‐Resolved Spectroscopy

Advanced Energy Materials, Volume 15, Issue 2, January 14, 2025.
This study comprehensively clarified the crucial correlation between crystalline disorder, charge‐carrier dynamics in mixed perovskite, and solar cell performance. Incorporating a trace amount of MAPbBr3 additive effectively mitigates and reduces the structural disorder of FAPbI3, resulting in excellent charge‐carrier dynamics and improved ...

Garnet Reference Materials for In Situ Lu‐Hf Geochronology

Geostandards and Geoanalytical Research, Volume 48, Issue 4, Page 887-908, December 2024.
Key Points First well‐characterised garnet reference materials for in situ Lu‐Hf geochronology via LA‐ICP‐MS/MS. The GWA reference materials yield robust and precise Lu‐Hf isochron ages. The ICP‐MS/MS sensitivity in gas‐mode increases substantially after flushing the reaction cell with NH3/He at a high flow rate (> 2 h prior to commencing analysis). In

Petrography, Crystallography, and Geochronology of Baddeleyite With Two Morphologies in a Chang'e‐5 Lunar Basalt

Journal of Geophysical Research: Planets, Volume 129, Issue 11, November 2024.
Abstract Baddeleyite (ZrO2) is widespread in lunar basalts and frequently used for U‐Pb geochronology of magmatic and impact events. The formation of baddeleyite involves two primary mechanisms: (a) crystallization from late‐stage magma, and (b) decomposition of zircon under high‐temperature (high‐T) conditions.

Bias‐Eliminating Techniques in the Computation of Power Spectra for Characterizing Gravity Waves: Interleaved Methods and Error Analyses

Earth and Space Science, Volume 11, Issue 10, October 2024.
Abstract Observational data inherently contain noise which manifests as uncertainties in the measured parameters and creates positive biases or noise floors in second‐order products like variances, fluxes, and spectra. Historical methods estimate and subsequently subtract noise floors, but struggle with accuracy.

Monitoring Water Level of a Surficial Aquifer Using Distributed Acoustic Sensing and Ballistic Surface Waves

Water Resources Research, Volume 60, Issue 8, August 2024.
Abstract Groundwater resources play an increasingly crucial role in providing the water required to sustain the environment. However, our understanding of the state of surficial aquifers and their spatiotemporal dynamics remains poor. In this study, we demonstrate how Rayleigh wave velocity variation can be used as a direct indicator of changes in the ...

Oxygen isotopic compositions of fresh rooftop micrometeorites from the Budel collection—Insights into the contemporary cosmic dust flux

Meteoritics &Planetary Science, Volume 59, Issue 6, Page 1236-1257, June 2024.
Abstract Cosmic dust particles originate from a wide variety of solar system and interstellar objects, including sources not identified among meteorite collections. Particles that survive atmospheric entry are retrieved on the Earth's surface as micrometeorites. The recovery of these micrometeorites has recently advanced to rooftop sites.
