Subsystems of the Galactic halo, their structures and compositions
Odessa Astronomical Publications, 2017 It is shown that general populations of globular clusters and metal-poor field stars are components at least of three subsystems occupying different volumes in the Galaxy.

Osteogenic Effects of Ion Released from Biodegradable Metallic Magnesium and Calcium Coating
Advanced Biology, EarlyView.This study explores how magnesium–calcium coatings on titanium promote osteogenesis by releasing ions and elevating pH during degradation. Using osteoblast‐like cells, the research demonstrates that both ion release and pH changes contribute to cell proliferation, differentiation, and mineralization, offering new insights into the design of bioactive ...

The Ages of the Thin Disk, Thick Disk, and the Halo from Nearby White Dwarfs
, 2017 We present a detailed analysis of the white dwarf luminosity functions derived from the local 40 pc sample and the deep proper motion catalog of Munn et al (2014, 2017).

Advanced Engineering Materials, EarlyView.A robot‐assisted laser processing method is proposed that enables the formation of surface‐tilted microanchors on metal substrates to improve metal–polymer joining. Using a six‐axis robotic platform, the laser beam's incidence angle, scanning path, and interline pitch can be precisely controlled, allowing the deliberate overlap of heat‐affected zones ...

The Thickness of Galaxy Disks from z = 5 to 0 Probed by JWST
The Astrophysical Journal LettersAlthough a thick disk is a structure prevalent in local disk galaxies and also present in our home Galaxy, its formation and evolution are still unclear.

Graphene overcoats for ultra-high storage density magnetic media
Nature Communications, 2021 The main limitation to the areal storage density of hard disk drives (HDDs) is the thickness of carbon overcoats protecting the disk media. Here,
