Radio follow-up observations of stellar tidal disruption flares: Constraints on off-axis jets
EPJ Web of Conferences, 2012 Observations of active galactic nuclei (AGN) and X-ray binaries have shown that relativistic jets are ubiquitous when compact objects accrete. One could therefore anticipate the launch of a jet after a star is disrupted and accreted by a massive black ...

Advanced Materials, EarlyView.This review explores how in situ and operando spectroscopic techniques reveal the real‐time behavior of reticular materials, including MOFs and COFs. These methods track material formation and functionalization, structural changes, defect formation, dynamic responses to external triggers, and catalytic processes.

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.

Topology in Biological Piezoelectric Materials
Advanced Materials, EarlyView.This review summarizes the topological structures in biological piezoelectric materials, covering morphology evolution, spatial arrangement, and biomimetic strategies. These topologies modulate structure‐property relationships across multiple scales, enabling performance enhancement and multifunctional integration.

The Astrophysical JournalWe 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.

Designing Physical Unclonable Functions From Optically Active Materials
Advanced Materials, EarlyView.Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

JWST Reveals Powerful Feedback from Radio Jets in a Massive Galaxy at z = 4.1
The Astrophysical JournalWe report observations of a powerful ionized gas outflow in the z = 4.1 luminous radio galaxy TNJ1338-1942 hosting an obscured quasar using the Near Infrared Spectrograph (NIRSpec) on board JWST.

Advanced Materials, EarlyView.A unique tri‐system interlocking top‐encased structure is formed for tin‐lead perovskites by the introduction of novel CGA additive. The fabricated tin‐lead perovskite NIR photodetector shows an outstanding specific detectivity of 2 × 1013 Jones at 940 nm, and the integrated 64 × 64 array demonstrates clear and accurate imaging abilities.
