PiFM and PiF-IR are the next generation of infrared spectroscopy techniques. PiFM brought a major shift to atomic force microscopy by adding chemical mapping capabilities. PiF-IR, its sister technique ...

Photothermal AFM-IR, commonly referred to as AFM-IR, is an analytical technique used to understand the chemistry of a material at the nanoscale. It combines the nanoscale spatial resolution of atomic ...

NIR spectroscopy concerns the analysis of how NIR light and matter interact. In spectroscopic analysis, light is determined by the wavelength, not by the applied energy. The wavelength of light is ...

Terahertz time-domain spectroscopy (THz-TDS) provides new insights into oxygen vacancy oscillation modes in amorphous zirconia films. Researchers ...

How it works: the top frequency comb is passed through a sample of interest and then into a beamsplitter. The bottom frequency comb operates at a slightly different pulse repetition frequency and is ...

Researchers from the Molecular Physics and Physical Chemistry departments of the Fritz Haber Institute have shown how two ...
