A Biologically‐Architected Wear and Damage‐Resistant Nanoparticle Coating From the Radular Teeth of Cryptochiton stelleri

Advanced Functional Materials, EarlyView.
The ultrahard teeth of mollusks that feed on rocky substrates contain a wear‐resistant coating on their surfaces consisting of densely packed mesocrystalline magnetic nanoparticles within an organic matrix. These coatings display significant hardness and toughness through their highly controlled mesocrystalline architectures.

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

Monthly notices of the Royal Astronomical Society, 2018
Stellar-remnant black holes (BH) in dense stellar clusters comprise a natural setup to trigger general-relativistic (GR) inspiral and merger of binary black holes (BBH), detectable by the LISA and the LIGO-Virgo, through dynamical encounters inside such ...

Clustering Properties of Intermediate and High-mass Young Stellar Objects

The Astronomical Journal, 2023
We have selected 337 intermediate- and high-mass young stellar objects (YSOs; 1.5–20 M _⊙ ) well-characterized with spectroscopy. By means of the clustering algorithm HDBSCAN, we study their clustering and association properties in the Gaia DR3 catalog ...

Between the Cosmic-Ray “Knee” and the “Ankle”: Contribution from Star Clusters

The Astrophysical Journal
We show that massive, young star clusters may be possible candidates that can accelerate Galactic cosmic rays (CRs) in the range of 10 ^7 –10 ^9 GeV (between the “knee” and “ankle”).

Dynamics of massive stellar black holes in young star clusters and the displacement of ultra-luminous X-ray sources

, 2011
In low-metallicity environments, massive stars might avoid supernova explosion and directly collapse, forming massive (~25-80 solar masses) stellar black holes (MSBHs), at the end of their life.

Advancing from MOFs and COFs to Functional Macroscopic Porous Constructs

Advanced Materials, EarlyView.
This review study investigates the recent progress and methodologies for manufacturing metal–organic framework (MOF) or covalent–organic framework (COF)‐based 3D structured macroscopic porous constructs with high structural integrity, providing the possibility to control their porosity across dimensions.

Nebular C iv λ1550 Imaging of the Metal-poor Starburst Mrk 71: Direct Evidence of Catastrophic Cooling

The Astrophysical Journal Letters, 2023
We use the Hubble Space Telescope Advanced Camera for Surveys to obtain the first spatially resolved, nebular imaging in the light of C iv λ λ 1548, 1551 by using the F150LP and F165LP filters. These observations of the local starburst Mrk 71 in NGC 2366
