Mid-infrared feed-forward dual-comb spectroscopy at 3 $μ$m [PDF]
Proceedings of the National Academy of Sciences of the United
States of America 116, 3454-3459 (2019), 2018 Mid-infrared high-resolution spectroscopy has proven an invaluable tool for the study of the structure and dynamics of molecules in the gas phase. The advent of frequency combs advances the frontiers of precise molecular spectroscopy. Here we demonstrate, in the important 3-{\mu}m spectral region of the fundamental CH stretch in molecules, dual-comb ...

Thermal-emission measurements near room temperature using Fourier-transform infrared spectroscopy [PDF]
Phys. Rev. Applied 11, 014026 (2019), 2018 Accurate characterization of thermal emitters can be challenging due to the presence of background thermal emission from components of the experimental setup and the surrounding environment. This is especially true for an emitter operating close to room temperature.

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.
