Monitoring of multi-frequency polarization of gamma-ray bright AGNs

EPJ Web of Conferences, 2013
We started two observing programs with the Korean VLBI Network (KVN) monitoring changes in the flux density and polarization of relativistic jets in gamma-ray bright AGNs simultaneously at 22, 43, 86, 129 GHz.

A Comparative Analysis of Plasmonic and Dielectric Metasurface Sensing Platforms Powered by Bound States in the Continuum

Advanced Functional Materials, EarlyView.
This work reveals a fundamental trade‐off between plasmonic and dielectric metasurfaces for molecular sensing. A clear performance crossover is identified: dielectric metasurfaces excel in air, while plasmonic metasurfaces dominate in lossy solvents. These results establish design rules for infrared metasurface sensors and enable optimized performance ...

A Case Study of Gas Impacted by Black-hole Jets with the JWST: Outflows, Bow Shocks, and High Excitation of the Gas in the Galaxy IC 5063

The Astrophysical Journal
We present James Webb Space Telescope MIRI data of the inner ∼3 × 2 kpc ^2 of the galaxy IC 5063, in which the jets of a supermassive black hole interact with the gaseous disk they are crossing.

Bistable Photochromic Guest–Host Liquid Crystals for Rewritable and Switchable Photonic Devices

Advanced Functional Materials, EarlyView.
A photochromic DTCP‐based liquid crystal dye is incorporated into cholesteric liquid crystals (CLCs) to achieve optically and electrically tunable multistable states. In the open‐ring form, the system exhibits three electrically stable textures—planar, focal conic, and uniformly lying helix (ULH)—corresponding to reflective, scattering, and transparent

Impact of Radio-mode Feedback on the Covering Fraction of the Circumgalactic Medium of Quasars

The Astrophysical Journal
Utilizing data from the Low-Frequency Array Two-meter Sky Survey and the Sloan Digital Sky Survey, we assemble a sample of 1469 projected quasar pairs with detected radio emissions from foreground quasars, as well as a control sample of 5846 pairs ...

Generating Cell Surface Nucleated Hydrogels with an Artificial Membrane‐Binding Transglutaminase

Advanced Functional Materials, EarlyView.
Cell‐based therapies require advanced strategies to enhance cell delivery and bioactivity. Cell membrane engineering offers an avenue to impart new functions to delivered cells to boost their viability and function. Here, an artificial membrane‐binding transglutaminase is generated and biophysically characterized.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.
