Thermochromic Gires‐Tournois Resonators with Tellurium for Battery Thermal Runaway Warning

Advanced Materials, EarlyView.
A thermochromic Gires‐Tournois (GT) resonator with a thin tellurium layer enables rapid, reversible, and untethered detection of battery surface temperature <80 °C. Exploiting tellurium's refractive index change driven by a thermally induced phase transition between solid and quasi‐liquid states, the GT resonator visualizes heat propagation, providing ...

Multiple Emission Regions in Jets of the Low-Luminosity Active Galactic Nucleus in NGC 4278

The Astrophysical Journal
The Large High Altitude Air Shower Observatory (LHAASO) has detected very-high-energy gamma rays from the low-ionization nuclear emission-line region galaxy NGC 4278, which has a low-luminosity active galactic nucleus (LLAGN) and symmetric, mildly ...

Discovery of the first giant double radio relic in a galaxy cluster found in the PLANCK Sunyaev-Zel'dovich cluster survey: PLCK G287.0+32.9

, 2011
We report the discovery of large scale diffuse non-thermal radio emission in PLCK G287.0+32.9, an exceptionally hot (T ~ 13 keV), massive and luminous galaxy cluster, strongly detected by the PLANCK satellite in a recent, all-sky blind search for new ...

Plasma and Warm Dust in the Collisional Ring Galaxy VIIZw466 from VLA and ISO Observations [PDF]

, 1999
We present the first mid-infrared (Mid-IR) ($\lambda5-15\mu$m) and radio continuum ($\lambda\lambda$20,~6 and 3.6 cm) observations of the star-forming collisional ring galaxy VII Zw 466 and its host group made with the Infrared Space Observatory and the ...

Developmental Hypoxia Enhances Kidney Organoid Complexity and Maturity

Advanced Science, EarlyView.
The current bottleneck in metanephric mesenchyme (MM)‐derived nephron organoid development is the absence of a connected network of collecting ducts (CD) derived from the ureteric bud (UB). To address this limitation, this study proposes a hypoxia‐based differentiation method that mimics the natural renal developmental environment, enabling the ...

Jet Interaction with Galaxy Cluster Mergers

The Astrophysical Journal
Active galactic nucleus (AGN) bubbles in cool-core galaxy clusters are believed to facilitate the transport of cosmic-ray electrons (CRe) throughout the cluster.

The innermost region of the water megamaser radio galaxy 3C403

, 2007
The standard unified scheme of active galactic nuclei requires the presence of high column densities of gas and dust potentially obscuring the central engine.

Low-frequency radio emission in the massive galaxy cluster MACS J0717.5 + 3745 [PDF]

, 2013
International audienceTo investigate the nonthermal emission mechanism and their interaction during cluster mergers, we analyze multiple low-frequency radio data for the X-ray luminous massive galaxy cluster MACS J0717.5 + 3745, located at z = 0.5548 ...

A Degradable Bioinspired Flier with Aerogel‐Based Colorimetric Sensors for Environmental Monitoring

Advanced Science, EarlyView.
Biodegradable fliers are developed inspired by Tipuana tipu samaras, integrating cellulose nanocrystal aerogel (CNCa) sensors loaded with natural dyes for pH and ammonia detection. The lightweight, degradable fliers mimic natural morphology and aerodynamics, offering an eco‐friendly, scalable solution for in situ environmental monitoring after passive ...
