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.

Effect of Mo-doping on the structure, magnetic and optical characteristics of nano CuCo2O4

Journal of Materials Research and Technology, 2021
The changes in the properties of the supercapacitor electrode material copper cobaltite, prepared by a simple hydrothermal procedure, were investigated upon doping with Mo with different ratios (CuCo1-xMoxO4, x = 0.0, 0.1, 0.2).

Application of relativistic scattering theory of x rays to diffraction anomalous fine structure in Cu [PDF]

, 1998
We apply our recent first-principles formalism of magnetic scattering of circularly polarized x rays to a single Cu crystal. We demonstrate the ability of our formalism to interpret the crystalline environment related near-edge fine structure features in

X-ray magnetic diffraction under high pressure

IUCrJ, 2019
Advances in both non-resonant and resonant X-ray magnetic diffraction since the 1980s have provided researchers with a powerful tool for exploring the spin, orbital and ion degrees of freedom in magnetic solids, as well as parsing their interplay.

On the diffraction pattern of C60 peapods

, 2004
We present detailed calculations of the diffraction pattern of a powder of bundles of C$_{60}$ peapods. The influence of all pertinent structural parameters of the bundles on the diffraction diagram is discussed, which should lead to a better ...
