| Using LIBS to Track Uranium Materials |
|
Laser induced breakdown spectroscopy has been applied as quantitative and qualitative analytical method for a variety of matrices. A paper published in Applied Spectroscopy in 2018 was chosen by from the North American Society for LIBS and the Society for Applied Spectroscopy as the best paper on the topic of LIBS. In this paper, a molten salt aerosol–LIBS instrument was used to measure the uranium content in a ternary UCl3–LiCl–KCl salt matrix to investigate the development of a near real-time analytical method. We spoke with Ammon Williams, the primary author, who is currently with the Idaho National Laboratory about this work.

| Measurement of the Temperature Dependence of Water Using a Near-Infrared Raman Spectrograph |
|
The spectral behavior of water is studied using Raman with an NIR spectrograph and dual wavelength lasers for measurements of both the fingerprint and the OH stretching regions. Raman spectra are recorded between 5 ⁰C and 80 ⁰C, and treated with both band-fitting and the 2D-COS algorithm revealing improved insights into the spectral behavior of water.

| Criteria for High-Quality Raman Microscopy |
|
Five key qualitative factors–speed, sensitivity, resolution, modularity and upgradeability, and combinability–contribute to the quality of confocal Raman imaging microscopes. Using application examples, this article introduces modern Raman imaging and correlative imaging techniques, and presents state-of-the-art practice examples from polymer research, pharmaceutics, low-dimensional materials research, and life sciences.

| Rapid, Portable Pathogen Detection with Multiplexed SERS-based Nanosensors |
|
A new application of surface-enhanced Raman spectroscopy (SERS) is described for quantifying low concentrations of pathogens with high reproducibility. In this novel assay, bacteria are captured and isolated using functionalized metal nanoparticles for rapid optical identification via SERS. Initial tests with a portable SERS system validated the ability to identify the presence of Escherichia coli and methicillin-resistant Staphylococcus aureus bacteria.
