Plasma irradiation removes graphite from the pencil lead, exposing a thin layer of clay. By controlling the exposure time, the thickness of this layer can be varied to modulate the infrared (IR) ...

An established tool for the authentication and conservation of fine art paintings, Fourier-transform infrared spectroscopy (FTIR) typically requires the removal of small sample sections for analysis.

DRIFTS is routinely used in quality control applications, materials characterization, and catalytic studies in industrial and research settings. However, optimal instrument setup and sample ...
