Dual Optical Hyperbolicity of PdCoO2 and PdCrO2 Delafossite Single Crystals

open access: yesAdvanced Functional Materials, EarlyView.
In this work, the hyperbolic response of PdCoO₂ and PdCrO₂ delafossites is investigated for the first time. They exhibit dual hyperbolic regimes, one localized around a phonon absorption in the mid‐infrared spectral region, and the other extending into the visible range.

Defects Dynamic in Photo‐Excited CeO2 and their Influence on CO2 Photoreduction

open access: yesAdvanced Functional Materials, EarlyView.
X‐ray photoelectron spectroscopy study under light excitation is presented to track the defect dynamic (Ce4+ to Ce3+) in CeO2. Surface enhanced Raman spectroscopy confirmed the key role of Ce3+ states in controlling charge and energy transfer across the CeO2‐dye molecule interface.

Toward Noninvasively Imaging pH at the Surface of Implanted Orthopedic Devices in Live Rabbits Using X‐ray Excited Luminescence Chemical Imaging

open access: yesAdvanced Healthcare Materials, EarlyView.
Imaging pH in a live rabbit at the surface of a sensor‐coated titanium plate using X‐ray excited luminescent chemical imaging (XELCI). A raster scanning X‐ray beam generates radioluminescence from a spot on the sensor, and the luminescence passes through the tissue and is collected at two wavelengths to determine local pH.

Multi-messenger astrophysics of black holes and neutron stars as probed by ground-based gravitational wave detectors: from present to future

open access: yesFrontiers in Astronomy and Space Sciences
The ground-based gravitational wave (GW) detectors LIGO and Virgo have enabled the birth of multi-messenger GW astronomy via the detection of GWs from merging stellar-mass black holes (BHs) and neutron stars (NSs).

Near-Earth Supernova Explosions: Evidence, Implications, and Opportunities [PDF]

open access: yes, 2019
There is now solid experimental evidence of at least one supernova explosion within 100 pc of Earth within the last few million years, from measurements of the short-lived isotope ⁶⁰Fe in widespread deep-ocean samples, as well as in the lunar regolith ...
