Disk-locking Regulates Stellar Rotation in Young Clusters: Insights from NGC 2264

open access: yesThe Astrophysical Journal
Many young clusters possess extended main sequences, a phenomenon commonly ascribed to stellar rotation. However, the mechanism behind their very wide stellar rotation distributions remains unclear.

Sustainable Electrochemical Synthesis of High‐Quality MXenes: Mechanistic Insights, Applications, Challenges, and Technological Prospects

open access: yesAdvanced Functional Materials, EarlyView.
Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale

The star formation history of early-type galaxies in the fornax cluster [PDF]

open access: yes, 1998
We have measured central line strengths and line-strength gradients for a complete sample of early-type galaxies in the Fornax cluster, comprising 11 elliptical and 11 lenticular galaxies, more luminous than M(_B) = -17.

Using Detailed Single-star and Binary-evolution Models to Probe the Large Observed Luminosity Spread of Red Supergiants in Young Open Star Clusters

open access: yesThe Astrophysical Journal Letters
Red supergiants (RSGs) represent a late evolutionary stage of massive stars. Recent observations reveal that the observed luminosity range of RSGs in young open clusters is wider than expected from single-star evolution models.

Low‐Fraction Irregular Inclusions Trigger Large Compression Stiffening in Biopolymer Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
Irregular inclusions at low filler fractions trigger large compression stiffening in biopolymer hydrogels. By promoting contact‐network formation under compression, these inclusions induce non‐affine rearrangements, stretch surrounding fibers, and provide parallel load‐bearing pathways.

The Dynamical Ejections of Massive Stars from Young Star Clusters [PDF]

open access: yes, 2017
Massive stars form in star clusters or OB associations which may be expanded clusters. Such stars can be expelled with a high velocity from their birth cluster through a strong close encounter with other cluster members.

Coaxially Electrospun Myocardial dECM‐ Based Nanofibrous Scaffolds Demonstrate Enhanced Cardiomyocyte Biocompatibility

open access: yesAdvanced Healthcare Materials, EarlyView.
Our coaxial electrospinning system is capable of incorporating decellularized myocardial extracellular matrix in a core‐sheath configuration, creating nanofibrous scaffolds. These scaffolds, in turn, support the maintenance of functional cardiomyocytes adhered to the surface of these bioactive scaffolds.
