Sticking of Fine Particles in High-velocity Impact: Application to Size Distribution of Dust Grains in a Debris Disk

The Astrophysical Journal, 2023
Impact experiments were conducted at a velocity of ∼0.2–1.0 km s ^−1 using fine particles with several microns or submicrons in size. For metal (Cu) plate targets, as observed in previous impact experiments using projectiles with sizes larger than tens ...

Biologically Active Implants Prevent Mortality in a Mouse Sepsis Model

Advanced Healthcare Materials, EarlyView.
A modular, triple‐action titanium implant is developed to prevent implant‐associated infections by repelling bacteria, killing pathogens, and enhancing tissue integration. Coatings with phage cocktails targeting P. aeruginosa and S. aureus show significant bacterial reduction and improved survival in a mouse sepsis model.

JWST/NIRCam Detection of the Fomalhaut C Debris Disk in Scattered Light

The Astrophysical Journal Letters
Observations of debris disks offer important insights into the formation and evolution of planetary systems. Though M dwarfs make up approximately 80% of nearby stars, very few M dwarf debris disks have been studied in detail—making it unclear how or if ...
