Applications of Fourier transform infrared spectroscopy, Fourier transform infrared microscopy and near‐infrared spectroscopy to cancer research [PDF]

Journal of Spectroscopy, 2003
Glycogen levels in human lung and colorectal cancerous tissues were measured by the Fourier transform (FT‐IR) spectroscopic method. Reliability of this method was confirmed by chemical analyses of the same tissues used for the FT‐IR spectroscopic measurements, suggesting that this spectroscopic method has a high specificity and sensitivity in ...

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.
