Unlocking the Power of Hyperspectral Imaging: A Game-Changer for Agriculture, Medicine, and More
October 15th 2024Hyperspectral imaging (HSI) is revolutionizing fields such as agriculture, food safety, and medical analysis by providing high-resolution spectral data. This emerging technology is proving invaluable in diverse applications, including plant stress detection, weed discrimination, and flood management. A new review explores HSI’s fundamental principles, applications, and future research directions.
Simultaneous Determination of 50 Elements in Geological Samples by ICP-MS Combined with ICP-OES
October 15th 2024A method combining inductively coupled plasma–mass spectrometry (ICP-MS) with inductively coupled plasma–optical emission spectrometry (ICP-OES) was developed for multielement determination of 50 species of major, minor, micro, and trace, rare earth, and rare elements in geological samples.
New Hyperspectral Imaging Database Enhances Human Skin Research
October 14th 2024Researchers from the University of Minho (Portugal) have developed a hyperspectral imaging database of human facial skin, aimed at improving various scientific applications such as psychophysics-based research and material modeling. The database includes 29 participants with diverse skin tones, providing detailed spectral reflectance data under controlled conditions.
Spectroscopy Magazine sits down with Benjamin T. Manard of the Chemical Sciences Division at Oak Ridge National Laboratory (Oak Ridge, Tennessee), who will be receiving the Lester W. Strock Award, given by the New England Section of the Society for Applied Spectroscopy, this October.

The Big Review II: The Physical Mechanism of Infrared Absorbance and Peak Types
October 10th 2024In the second installment of “The Big Review,” we discuss the physical mechanism behind how molecules absorb infrared (IR) radiation. Because light can be thought of as a wave or a particle, we have two equivalent pictures of IR absorbance. We also discuss the quantum mechanics behind IR absorbance, and how this leads to the different peak types observed in IR spectrum.
