ALMA-LEGUS. I. The Influence of Galaxy Morphology on Molecular Cloud Properties

open access: yesThe Astrophysical Journal
We present a comparative study of the molecular gas in two galaxies from the Legacy ExtraGalactic UV Survey (LEGUS) sample: barred spiral NGC 1313 and flocculent spiral NGC 7793.

Stellar-mass black holes in young massive and open stellar clusters and their role in gravitational-wave generation [PDF]

open access: yes, 2016
The study of stellar-remnant black holes (BH) in dense stellar clusters is now in the spotlight, especially due to their intrinsic ability to form binary black holes (BBH) through dynamical encounters, that potentially coalesce via gravitational-wave (GW)

A Roadmap for Plasma‐Enabled Electrocatalysis in Urea Production

open access: yesAdvanced Materials, EarlyView.
A modular plasma—electrochemical platform enables fully electrified urea synthesis from air and CO2 under ambient conditions. This Review integrates plasma oxidation, C─N coupling electrolysis, mechanistic insights, and techno‐economic metrics into a roadmap for scalable, distributed, and renewable fertilizer production.

Star cluster disruption in the starburst galaxy Messier 82

open access: yes, 2014
Using high-resolution, multiple-passband Hubble Space Telescope images spanning the entire optical/near-infrared wavelength range, we obtained a statistically complete sample, $U$-band selected sample of 846 extended star clusters across the disk of the ...

Electrolyte‐Jet 3D Printing of Copper‐Based Strain Sensors for Physiological Signal Monitoring and Robotic Manipulation

open access: yesAdvanced Materials Technologies, EarlyView.
Electrolyte‐jet (EJ) 3D printing turns copper ions into precisely arranged copper microspheres, which combine with flexible polymers and carbon nanomaterials to create durable, high‐sensitivity sensors. These sensors accurately monitor human motion and physiological signals. Real‐time robotic hand control via gesture mirroring demonstrates an intuitive

On the Correlation between Young Massive Star Clusters and Gamma-Ray Unassociated Sources

open access: yesThe Astrophysical Journal Letters
Star clusters (SCs) are potential cosmic-ray accelerators and therefore are expected to emit high-energy radiation. However, a clear detection of gamma-ray emission from this source class has only been possible for a handful of cases.

Wrinkle‐Template Confinement of Kinetically Arrested Cellulose Nanocrystals for Sustainable Large Scale Reflection Gratings

open access: yesAdvanced Optical Materials, EarlyView.
Self‐supported all‐cellulose reflective gratings are fabricated from cellulose nanocrystal dispersions via a confinement printing process. Taking advantage of the reduced fluidity of concentrated, kinetically arrested cellulose nanocrystal dispersions, line arrays can be successfully transferred to dried CNC films.

Massive Interacting Binaries Enhance Feedback in Star-forming Regions

open access: yesThe Astrophysical Journal
We present a new framework to incorporate feedback from massive interacting binaries in simulations of star cluster formation. Our new feedback model adds binary stellar evolution to the cluster formation code Torch , and couples it in Amuse to the ...

The Star Cluster Population in the Tidal Tails of NGC 6872

open access: yes, 2005
We present a photometric analysis of the rich star cluster population in the tidal tails of NGC 6872. We find star clusters with ages between 1 - 100 Myr distributed in the tidal tails, while the tails themselves have an age of less than 150 Myr. Most of

A Study on the Cell Layer Patterns of a Citrus Periclinal Chimera Reveals β‐Cryptoxanthin Regulation in Citrus Fruits

open access: yesAdvanced Science, EarlyView.
Researchers have identified a citrus chimera with distinctive tissue origins and carotenoid profiles. It is discovered that fruit tissues develop from all three cell layers but in different proportions. A key transcription factor, MYB107, regulates β‐cryptoxanthin production by directly activating carotenoid biosynthesis genes, explaining why some ...
