A Different Perspective on the Solid Lubrication Performance of Black Phosphorus: Friend or Foe?
Advanced Engineering Materials, EarlyView.Researchers investigate black phosphorus (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.

Conductance quantization suppression in the quantum Hall regime
Nature Communications, 2018 Conductance quantization is the hallmark of non-interacting confined systems. The authors show that the quantization in graphene nanoconstrictions with low edge disorder is suppressed in the quantum Hall regime.
