Dust traps and gas kinematic signatures in a crescent structure of a planet-forming disk
Frontiers in Astronomy and Space SciencesIn the past few years, ALMA unveiled a variety of substructures (rings, spirals, crescents) in the continuum emission of most protoplanetary disks imaged at high spatial resolution.

Advanced Functional Materials, EarlyView.Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Imaging of 2-mm dust continuum emission towards S106 FIR and its spectral energy distribution [PDF]
Symposium - International Astronomical Union, 2002 The class 0 source S106 FIR is a good candidate to investigate a very early phase of star formation because of the presence of an AU-scale Microjet, discovered by our VLBA H2O maser observations and the absence of an extensive CO outflow. In order to reveal the properties of S106 FIR, we conducted observations of 2-mm continuum emission with the ...

The Astrophysical JournalThe recent discovery of a galaxy at z = 7.3 with undetected optical emission lines and a blue UV-to-optical continuum ratio in JWST spectroscopy is surprising and needs to be explained physically.

Advanced Functional Materials, EarlyView.Establishment of bidirectional communication behavior between natural and artificial cells. The first type of communication from natural dendritic cells to artificial polymeric cells was achieved via ATP release after cell lysis. The released ATP was taken up via gated UV‐controlled permeability increase of the polymeric membrane for performing ...

The Astrophysical JournalMeasuring the strength of a three-dimensional (3D) magnetic field vector is challenging as it is not easy to recognize whether its line-of-sight (LOS) and plane-of-sky (POS) components are obtained from the same region.

Comparison of ¹³CO line and far-infrared continuum emission as a diagnostic of dust and molecular gas physical conditions: III. systematic effects and scientific implications [PDF]
, 2007 Far-infrared continuum data from the COBE/DIRBE instrument were combined with Nagoya 4-m ¹³CO J = 1 → 0 spectral line data to infer the multiparsec-scale physical conditions in the OrionA and B molecular clouds, using 140 μm/240 μm dust color ...

Advanced Functional Materials, EarlyView.A removable sacrificial polymer layer engineers the thermal boundary condition during nanosecond laser ablation of PET, suppressing heat‐affected‐zone formation without relying on costly ultrafast lasers. This strategy enables deep, high‐aspect‐ratio trenches with no detectable heat‐affected zone, templating silver‐filled mesh electrodes with record ...

Resolved Dust Emission and CO Isotopologues in Giant Molecular Clouds of the Andromeda Galaxy
The Astrophysical JournalDust emission at submillimeter wavelengths can be used to reliably trace the basic properties of molecular clouds. Early results from a recent Submillimeter Array (SMA) survey of the Andromeda galaxy (M31) include the first detections of resolved dust ...
