A Different Perspective on the Solid Lubrication Performance of Black Phosphorous: Friend or Foe?
Advanced Engineering Materials, EarlyView.Researchers investigate black phosphorous (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.

Mapping the Chemodynamics of the Galactic Disk Using the LAMOST and APOGEE Red Clump Stars
The Astrophysical Journal Supplement SeriesA detailed measurement is made of the metallicity distributions, kinematics, and dynamics of the thin and thick disks across a large disk volume (5.0 ≤ R ≤ 15.0 kpc and ∣ Z ∣ ≤ 3.0 kpc) by using the LAMOST–APOGEE red clump stars.

Advanced Engineering Materials, EarlyView.Additive manufacturing is a promising route for the production of Ni‐base superalloys for turbine applications, such as Inconel 718. Nonetheless, it induces various changes in the microstructure and performance of these materials. One such change is the incidence of the δ‐Ni3Nb phase, whose impact on microstructure, aging precipitate fractions, and ...

Thick disk and pseudobulge formation in a clump cluster
EPJ Web of Conferences, 2012 Bulges in spiral galaxies have been supposed to be classified into two types: classical bulges or pseudobulges. Classical bulges are thought to form by galactic merger with bursty star formation, whereas pseudobulges are suggested to form by secular ...

Enhanced Electrochemical Properties of Biobased Activated Carbon for Supercapacitors
Advanced Engineering Materials, EarlyView.Biobased activated carbons with diverse properties (pore size distribution, electrical conductivity, capacitance) for supercapacitors applications are synthesized and tested, using renewable biomass as versatile raw materials with disparate inherent heteroatom and molecular building blocks.

Thick disk kinematics from RAVE and the solar motion
EPJ Web of Conferences, 2012 We present a method to derive kinematic parameters for the Galactic thick disk based on stellar radial velocity data alone, without previous knowledge of distances.

Extragalactic Thick Disks: Implications for Early Galaxy Evolution [PDF]
arXiv, 2005 I briefly review the growing evidence that thick stellar disks surround most edge-on disk galaxies. Recent studies show that these extragalactic thick disks have old ages, low metallicities, long scale lengths, and moderately flattened axial ratios, much like the thick disk of the Milky Way.

Advanced Engineering Materials, EarlyView.Hybrid materials enable high‐performance components but are challenging to process. This study explores an inductive heating concept with spray cooling for steel–aluminum specimens in a two‐step process including friction welding and cup backward extrusion.
