Advanced Engineering Materials, EarlyView.The share of technical thermoplastics is expected to grow further in the e‐mobility segment. In this study, a detailed temperature‐based tribological characterization of technical thermoplastics is performed. The tribological properties are discussed in terms of the dynamic mechanical properties of polymers at different ambient temperatures. A proof of

Counterculture Stars: Slow and Retrograde Stars with Low-alpha Disk Abundances
The Astrophysical JournalThe Milky Way is home to a thin disk that can be defined via kinematics and/or elemental abundances. The elemental abundance-defined thin disk, also called the low-alpha disk, is generally thought to comprise stars on planar, circular orbits that ...

Magnetohydrodynamic simulations of black hole accretion [PDF]
, 2001 We discuss the results of three-dimensional magnetohydrodynamic simulations, using a pseudo-Newtonian potential, of thin disk (h/r ~ 0.1) accretion onto black holes.

Advanced Engineering Materials, EarlyView.In this research, ZrC coatings are evaluated against various counterprobes at the microscale using novel super‐stiff atomic force microscopy cantilevers. The chemical composition of the coating is shown to be an important factor influencing coating hardness and Young's modulus, while surface roughness, counterprobe hardness, and surface energy are the ...

The Kinematic Signature of the Warp and Waves in the Milky Way Disk
The Astrophysical JournalUsing over 170,000 red clump (RC) stars selected from LAMOST and APOGEE, we conduct a detailed analysis of the stellar V _Z as a function of L _Z (or R _g ) across different ϕ bins for various disk populations.

Vertical Structure of the Milky Way Disk with Gaia DR3
Galaxies, 2023 Using a complete sample of about 330,000 dwarf stars, well measured by Gaia DR3, limited to the galactic north and south solid angles |b|700 pc and points to the presence of more stars beyond the thin disk that cannot be accounted for by the two-disk ...

High‐Temperature Oxidation of the CrFeNi Medium‐Entropy Alloy
Advanced Engineering Materials, EarlyView.The oxidation behavior of equiatomic CrFeNi MEA is a key issue that determines this material's suitability for high‐temperature application. The understanding of long‐term behavior is even more crucial than short‐term corrosion effects. The alloy is exposed to synthetic air at 1000, 1050, and 1100 °C for 24, 100, and 1000 h and systematically compared ...
