Fourier-transform near-infrared (FT-NIR) spectroscopy continues to be a rapidly growing process analytical technique, particularly in the pharmaceutical and biopharmaceutical industry. The technique offers a number of advantages for online applications, and most of the major NIR instrument vendors now compete in this segment of the market.

Short Courses

In the realm of classical physics, Maxwell's equations still rule, just as Newton's equations of motion rule under normal conditions.

Surface plasmon resonance, charge-transfer resonance, and their combination determine the enhancement of surface-enhanced Raman scattering signals, and the varying intensities of the signal at different pH levels may result from the change in contributions of the combined system.

The detailed examination of the spectral behavior of three-component mixtures continues.

Algae and other aquatic species are promising sources for biomass that can be economically converted into fuel, and several infrared sampling techniques can be used to analyze these samples.
