Testing the consistency of early and late cosmological parameters with BAO and CMB data

Physics Letters B
The recent local measurements of the Hubble constant H0, indicate a significant discrepancy of over 5σ compared to the value inferred from Planck observations of the cosmic microwave background (CMB).

Probing and Tuning Strain‐Localized Exciton Emission in 2D Material Bubbles at Room Temperature

Advanced Materials, EarlyView.
This work provides an approach: 1) to directly visualize the associated exciton properties, revealing an intrinsic emission wavelength shift, and 2) actively modify local strain, enabling further exciton emission tuning. These findings provide direct insights into the strain‐localized emission dynamics in bubbles and establish a robust framework for ...

On the Feasibility of Deriving Pseudo-redshifts of Gamma-Ray Bursts from Two Phenomenological Correlations

The Astrophysical Journal
Accurate knowledge of gamma-ray burst (GRB) redshifts is essential for studying their intrinsic properties and exploring their potential applications in cosmology. Currently, only a small fraction of GRBs have independent redshift measurements, primarily

Micro‐Strain Responsive Near‐Infrared Mechanoluminescence for Potential Nondestructive Artificial Joint Stress Imaging

Advanced Materials, EarlyView.
In situ and real‐time stress sensing during total knee replacement procedure is expected to be realized based on near‐infrared mechanoluminescent phosphor of Sr3Sn1.98Sb0.02O6.99, which has the lowest strain sensitivity as low as 50 µst. Abstract Recently, joint replacement surgery is facing significant challenges of patient dissatisfaction and the ...

Li‐Well ZnO Memtransistors: High Reliability for Neuromorphic Applications

Advanced Materials, EarlyView.
A novel lithium (Li)‐well ZnO memtransistor integrates transistor switching and nonvolatile memory, akin to ferroelectric field‐effect transistors (FeFETs) and floating gates, while enabling low‐power operation via Li⁺ ion migration. Li⁺ ion migration and switching mechanisms were confirmed by 3D secondary ion mass spectrometry (SIMS).

Photometric Redshift Estimation of Quasars by a Cross-modal Contrast Learning Method

The Astronomical Journal
Estimating photometric redshifts (photo- z ) of quasars is crucial for measuring cosmic distances and monitoring cosmic evolution. While numerous point estimation methods have successfully determined photo- z , they often struggle with the inherently ill-

Spatially‐Controlled Planar Guided Crystallization of Low‐Loss Phase Change Materials for Programmable Photonics

Advanced Materials, EarlyView.
The concept of spatially‐controlled planar guided crystallization is a novel method for programming the growth of optically homogeneous low‐loss Sb2S3 phase‐change material (PCM), leveraging the directional crystallization within confined channels.
