Interference Measurements Across Vacuum and Atmospheric Environments for Characterization of Space-Borne Telescope

Photonics
A space-borne telescope is used for Earth observation at about 500 km above sea level in the thermosphere where the air density is very low and the temperature increases significantly during daytime. If the telescopes are aligned and characterized on the

SURE-Fuse WFF: A Multi-Resolution Windowed Fourier Analysis for Interferometric Phase Denoising

IEEE Access, 2019
Interferometric phase (InPhase) images, acquired by phase imaging systems, often suffer from two major degradations: 1) phase wrapping, caused by the sinusoidal 2π-periodic sensing mechanism, and 2) noise, introduced by the acquisition process or ...

2D copper nanozyme patches facilitate bone regeneration via interfacial modulation of osteoclast‐osteoblast dynamics

BMEMat, EarlyView.
This study develops a nano‐enzyme patch (ezPatch) targeting bone interfaces. Utilizing ligand‐to‐metal charge transfer (LMCT) catalysis and bone‐targeting ligands on copper nanosheets, ezPatch simultaneously scavenges reactive oxygen species (ROS) and generates oxygen in situ at bone‐losing sites.

Interferometry of ionospheric E-region irregularities based on Kunming VHF radars

Frontiers in Astronomy and Space Sciences
There is a long history of using VHF radar systems to detect ionospheric irregularities based on the theory of coherent scattering. According to previous work, there is a high occurrence of field-aligned irregularities (FAIs) in the ionospheric E-region ...

Pt‐TiO2 mesoporous nanosystem co‐delivering phlorezin enables synergistic sonodynamic‐chemoimmunotherapy for hepatocellular carcinoma via directly targeting DDX5 and metabolic reprogramming modulation

BMEMat, EarlyView.
Abstract Hepatocellular carcinoma (HCC), ranking as the third leading cause of cancer‐related mortality globally, continues to pose significant therapeutic challenges. Here, we developed an innovative nanosystem, Phl@PT, based on Pt‐TiO2 nanoparticles for the co‐delivery of Phlorezin, presenting a novel approach for HCC treatment through sonodynamic ...

Click Capture SELEX for the Identification of Click‐Modified Aptamers Targeting Small Molecules in Solution

Chemistry – A European Journal, EarlyView.
Using kanamycin A as a model target, we developed click‐capture SELEX to identify nucleobase‐modified aptamers capable of binding small molecules in solution. This approach enables flexible incorporation of nucleobase modifications via CuAAC, allowing the chemical properties of the aptamer to be tailored to the target molecule.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.
